For those interested, this is what I've installed my ASP inverter into... It's still a work in progress, but work is preceding nicely. !993 Chevy C3500HD with a 6.5 Turbo diesel engine. 112000 miles on the odometer. Onboard 7.5Kw split phase diesel generator. 400 liter fresh water tank...

Lol... you can never have too much power!!!! Unfortunate that means spending more then we want to sometimes... I know most of you out there don't want to use utility power at all BUT it is still nice to have it tested and wirking for those "what if" moments in life. On that note, I stress...

After doing a bit of research I've decided to bite the bullet myself and take a chance on buying an APS unit, with plans to buy a 2nd one later on, from here: SRNE 10KW Support Split/Single-phase 48V To 110/240VAC Hybrid Solar Inverter Dual MPPT Max 22A Charge Current Pv Max 500VOC Store: SRNE...

I try not to look back at current prices once I've bought something.... sticker shock can be extreme at times ( kicking myself in the ass, asking myself why didn't I wait for THAT sale....lol).

In my opinion, build your own pack, 16 x 280AH or bigger LiFePo4 batteries. In my setup I used an ANT BMS, 7-16s, 420amps continous, 1050 amps peak (I limited it to 280amps continous in the settings of the bms). ANT SMART BMS 7S to 16S This was the cheapest solution I was able to come up with...

My APS48100U200-H has just arived, manual shows UL1741 certification. It comes with only one parallel cable, see pics. When I get a chance, I'll do a pinout test on the connectors to see if it is a straight thru vga cable extension. I ordered the WIFI module as well. A couple large dents on the...

Ran into a frustrating issue with the 10KW ASP I just got. It refused to charge my batteries any higher then 1.5 amps... Only have it hooked up to the grid to rule out too many factors for now. I've been playing with the voltage settings in my ANT BMS and in the ASP over the last 2 days trying...

Hopefully it will be shipped soon. I'm curious to see how well the units work in parallel. I'm very tempted to order a second one later on when cash flow allows...

You are correct, my bad, I didn't notice the 0 degrees between phases part.... Page 28 of the manual is the correct way for North America. Thanks for the correction, greatly appreciated.

Yes I have the wifi module for it. I'm not impressed with the SolarMan Smart app at all. It only updates ever 5 minutes or longer, depending on their servers and some of the data it shows is not accurate. Here is a screenshot for todays load (red )and grid charging (green). BTW you can't zoom...

Install in progress....slow progress, but progress none the less. Hopefully, barring major interruptions I'll be able to wire it up tomorrow and do a quick test. Battery voltages as shipped: Lowest 3.283V, Highest 3.287V , most are at 3.285V More testing coming soon....as time allows.

Proper way to connect 2 SRNE ASP inverters in parallel, I hope this helps resolve the question on how to connect them:

I read thru the entire manual and it does not mention Supplements A nor B anywhere. Just plain old UL1741 According to a certificate I found for their HF series inverter it is listed as "UL1741:2010 Ed.2+R:16Sept2020" I haven't found a certificate for the ASF nor ASP series yet. A good...

About 3 or so weeks ago I swapped ot my dead/dying lead acid batteries. Replaced it with16 x 280Ah cells, new bms, new 10Kw SRNE inverter and new wiring. Took 2 weeks to learn and work the kinks out of the system, slow and steady without haste nor worry. This site has been a great source of...

That's what I was thinking as well, nothing else really makes sense. Be aware that the inverter is capable of 200% overload for very short periods of time. That means as an example: Worst case scenario (low batteries): 20000 watts / 46 volts = 434.78 amps !!! Best case (full...

Here's the link to the one I bought back in april: SRNE Power Store - AliExpress

@42OhmsPA I figured that you'd like those 4awg pin terminals. I hope they help you in current and future projects. BTW, they are rated for 125 amps max!

I agree wholeheartedly! Keep the fun times and info rolling till the magic smoke escapes??? .... meh... maybe a tad bit too far there on that test, lol.

I bought 3 of the 420 Amp 7s to 16s boards and I'm very happy with them so far. Still waiting on another 32 x 280Ah cells to be delivered by slow boat so I can use the other 2 boards...sigh... Have one of them connected to a 16s 280Ah VariCore LiFePo4 diy pack, current limited the boards in...

How big and what kind of a load did you put on it? What is the size of your battery bank and what is the BMS set for max current draw before it shuts down the battery? I'm curious and would like to know this to see if this is an issue I'll run into with my ASP. So far I've had it ideling at...

Remember that these are only possible solutions for what could be done... doesn't always mean you should do it, even if it would work in the end, the question is for how long and how safe? Personally, if this was my setup, I'd sell the 15s battery and buy a matching 16s that works with your new...

Converted to USD I paid about $1,564 with shipping and taxes included. That was back in the middle of april.

Great info. Thank you for that. I agree with you that TIG was wrong process, but they were only ones willing to at least try something. You can clearly see in my picture that the weld did not have good penetration and thus didn' bond well. I now worry about and question the quality and strength...

This is what the post looks like after the welding attempt. not looking good at all.

Please note that unlike DC wiring where you want to have a breaker on the gound and positive wires, in an AC circuit the Neutral wires in house wiring do not require a breaker, only the hot wires ( L1, L2) require the breakers. This is acording to all the electrical codes I've ever read in...

Manual mentions the following for installation: " 3.1 Installation location ASP series is only for indoor use (protection level: IP20). Before selecting the installationlocation, users should consider the following factors:  A solid wall  Installation height: flush with the line of sight ...

Has to do with the Dry Contact Port of the inverter. When the inverter enables "remote generator start" then the generator icon will light up on the panel.

Last night I managed to catch the tail end of a nice sale on batteries and couldn't resist buying them... VariCore 32 x 280AH for $960.22 Canadian (cheaper by a third, compared to my current 16 cells...lol), includes shipping, duties and taxes. Only downside is that I now have to wait 60 days...

Thanks for the heads up, forgot to delete the non redacted photos...lol...fixed now.

Ordered from "SRNE Power Store" on AliExpress. https://www.aliexpress.com/item/1005006779462705.html Was ordered and paid for on April 19, after some back and forth with the company it was finally shipped April 30 and came in today, May 10. Took longer then expected due to fedex issue in Hong...

Certificates I was sent by my seller, these are all he had access to. Part 1 of 2

Certificates I was sent by my seller, these are all he had access to. Part 2 of 2 He didn't have access to anything for UL1741

Do you happen to know the size of the wires inside your batteries? From the batteries to the BMS, then to the battery post? One of the problems with prepackaged batteries I've found is that it's imposible to know the size of the wires they used inside the sealed units (unless you want to void...

Thank you for that info. I confirmed it working on mine as well as soon as I changed setting 14 to be 0.4 volts higher then the value i wanted in setting 4 it allowed the change....sigh. Like you, I'm amazed that this info is not available in the manual...

So far I enjoy being on this site a lot. Lots to learn but also lots to share... best way to learn I find it to sometimes fail. Since failures are what make us question the why, where and when of it all sometimes. Besides, It's good to have great people to bounce ideas off of once in a while...

Contact paypal directly regarding this transaction, may have been Identified as suspicious for one reason or another... I'd verify with them. Batteries were in good condition when they arrived.. Still testing them, but so far lowest capacity one is at 287Ah. No bloating on any cells and no...

Makes my cheap chinese 34watt 4 foot led light flicker when the ac kicks on...lol. Bad power factor on startup, cheap light doesn't help either

Only way I've found to be able to use 4 awg wire in our setup with the ASP inverter is to use the following: 4 AWG Non Insulated Pin Terminals, 13/16" Pin, UL Approved,

Cells are made by VariCore. Grade A 3.2V 280Ah LiFePo4

I remember having to take that bloody course in Collage... tricky but corrent wording and phrasing.... don't use unnecessary nor ambiguous words. Ahhh...those were the good ol days when you actually had to know something, not like nowadays, from the looks of it anyhow. And thus googlebabies were...

Be careful about the max voltage of this item, 32 V max is not safe to use in a 16s LiFePo4 setup, sooner or later it may burn your place down. Flipping this switch under a heavier load at 48 or more volts will create a plasma arc between the contacts that will not extinguish, thus causing a...

In my opinion: Only safe thing to do for now to keep your costs down, would be to drain your new 16s pack to the same voltage as your 15s pack. Once that is done you can then connect the 16s pack in parallel to your 15s pack. Leave the settings on your inverter/charger as they were originally...

Well, on the bright side at least it's confirmed that the BMS is switching the batteries off due to overcurrent.... One of my reasons for upgrading to LiFePo4 batteries and new inverted was that my old lead acids were getting very old and on more then one occasion when the fridge/freezer/ac...

All above are great suggestions to try. Only other thing I would suggest, if you have a multimeter capable of showing the output frequency of the generators' AC output and see how close it is to 60 Hz. I have a 7.5 Kw diesel generator in my RV and my ASP 10Kw would not charge while connected to...

You shouldn't have an issue with dissimilar metals, unless you get the batteries wet (where they remain wet for an extended period of time) or they are constantly exposed to very high humidity... other then that I wouldn't worry about it. I called every welding shop in my city to see if anyone...

Found the info after a bit of looking, official documentation says that its less then 60dB of noise from the fan

I've had good overall results from multiple store on AliExpress over the last 3 years of buying stuff from China. One store did try to cheat me, they kept claiming that package was shipped for 2 weeks, yet the tracking number only showed "package not picked up from seller yet". Waited for 15...

That's the same store that I bought mine from, the price I paid for mine back at the beginning of april was : includes shipping, duties and taxes, converted to US dollars was $1,564 approximately. That was including the wifi module.

I'd be very wary of posted max limits.... sometimes you get lucky and nothing happens, but more othen then not the hardware will fail just below or close to those listed limits... usually there is a very short time limit of functionality at those limits. Milage will vary dependent on luck and...

On a side note, over 2 years ago I bought a used, pre-packaged 36 volt 65Ah LiFePo4 battery to power my computers UPS (uniterruptible power supply). Lithium Pros model M3265-36 with bluetooth connectivity. The thing that caught my attention was that the bms they were using was an ANT BMS. I've...

If it works, then it would be an easy way to convert your current ASF to an ASP and connected it to the 2 new ASPs you have yet to finish installing. I can just see your setup now with 30,000 watts of inverter AC power and 33,000 watts of solar controlled by the inverters, all at your...

We will know by the sudden and amazingly, excessivly large power increase spike you've ever seen going into your batteries and loads! Of course, by then we may not be alive to see and rejoyce about said increase in power, lol, but our panels may produce 200-600% more power before burning out.

When you get your ASPs up and running, please check if they are the same software version as mine... curious to see if they are. Mine is Software version: 8.17.12

Yes, I now own 3 of these. One is installed in my current pack and I'm still waiting for a shipment of an additional 32 x 280Ah cells to arrive. I do not have it setup due to lack of time at the moment for communications with my inverter but the settigs in the BMS do have comms available if you...

Based on the manual, if I'm understanding it properly, inverter one AC output supplies L1 power and inverter 2 AC output supplies L2 power. Thus setting 31 must be 2P2 and not 2P0 since you need the phase from L1 to L2 to be 180 degrees out of phase not 0 degrees as you currently have it setup...

Correction: After re-reading page 44 of the manual several dozen times and downloading a different manual to confirm, since it is a bit confusing... My interpretation is that setting 31 on inverter one should be 2P0 and inverter 2 should be 2P2 This should tell them to be 180 degrees out of...

That's what it looks like to me since it's a 13Kw split phase generator. Bare minimum you will need a 10Kw inverter, preferably a 12Kw just to handle your current load with possible surges when the AC starts up... Idealy, to be on the safe side and have extra power availabe for extras you may...

If neither of those fixes your problem then try changing to the following settings: 03 APL 06 AC1ST

Check setting 9 - Battery boost charge voltage - default is 57.2. Set it 58.4 and see if that changes your charging current, it did on my SRNE inverter. Setting 11 - Battery floating charge voltage - default is 55.2 Raise this value up slowly and check charging current as well.

Dangit...there you go poppin my bubble...sigh... In the end, I guess, when the power being supplied by your panels exceeds their rated sticker max power would be the day you know that there is a problem with our sun, or the neighbours newly repainded house is reflecting WAY too much light at...

In my opinion, your estimates are close enough, except the ac, you will find that you will be using it more then your estimate. I have no experience with the EG4 stuff so I can't help you there. I custom built my RV from a 19' moving box truck with overhang, no windows except the small crescent...

Initial delay from April 19 to April 30 was partially my fault by asking for additonal clarification on a couple matters pertaining to my particular situation...

I sent off a request to SRNE for a copy of the UL1741 certificate, waiting on a reply...

Turning your DC wires into heaters really bites in the summer time but may be a great thing to do in the winter time, ROFL..........

Now I'm curious to see their guts as well!!! Let the surgery begin, with all the gory little details please and thank you...

Yup, we can almost be considered close neighbours...lol... you're not that far away from where I live. A single tank of diesel there and back in my Jetta TDI.

3 posibilities I can think of, if nothing else changed except for moving the panels around. 1 - your charge controller has developed a fault and is not supplying full power, unlikely but possible. 2 - more then one solar panel has become damaged during the move, very possible, disconnect all...

Another thing to note, most BMS boards will allow you disable/turn off charging only for a short time. After that they turn it back on automatically, timeouts vary on different bms boards, so please verify if that is also the case with your boards. Mine resets after 5 minutes. or so

Excerpt from home depot site for that wire: "This SER cable features compact-stranded, aluminum-alloy conductors. " Do not use aluminum wire in your setup, that's just asking for trouble... Stick with stranded copper wire only. Solid copper may work as well, but it is a b*tch to pull thrugh...

lol...isn't that why they sell blue spray paint in various shades??? :unsure:

I bought mine on AliExpress. Alibaba is also an option, so long as you don't mind waiting for the slow boat shipping (approx. 60 days or so)... but remember that the quality will vary greatly between different vendors on these platforms, so your milage will vary.

Thank you for the software version, I don't know how big a difference software wise it makes between the ASF you have there and the ASP. your ASF: 8.15 1.04 my ASP:8.17.12 1.04 Makes me wonder, if you were to add the parts the ASF is mising that the ASP has and reflash the ASF with the ASP...

If you do then please sell tickets to the show, Pay Per View style could make you enough cash to buy a new system :sneaky:

I got frustrated with Alibaba stores agressivly pushing mass volume purchases, so personally I avoid using Alibaba, just my preference... everyone gets different milage after all...

For those who may be interested in inverter settings, they are listed below. Inverter: SRNE ASP48100U200-H, Software version: 8.17.12, wifi module is connected and setup. Inverter settings that work for my setup (may be changed at a future date)...... heck, whom am I kidding, something will...

Thank you, that helps.

The drawing is direct from the SRNS Power Store on Aliexpress. When you run a single SRNE 10Kw ASP inverter in single phase mode you will get 120 Vac out at 10,000 watt (126 max amps gives you the 15Kw listed in the specs). In split phase mode, for a singe inverter you will only get 120Vac 5000...

Just like common sense.... gone but not forgotten and more of a super power then anything else.

No worries about changing topic, it's still related to the original problem you are having after all, imo. Have you tried to put a voltmeter across the battery input terminals on the inverters, then start the AC and take note of how low the voltage sags? I'd do this for both inverters, may...

P1 and P2 refers to the phases. As in all inverters connected only to L1 output are marked as P1, and all inverter connected only to L2 output are marked as P2 for phase 2. They should be 180 degrees out of phase from each other. What is the exact model number of your inverter and which diagram...

Perfect example of voltage drop in my system right now: My positive wire from batteries to inverter is about 6 feet long (will be shortened later) 1/0 AWG, AC fridge, freezer, PC and one 4 foot light are all running right now. Approx 2200 watt average load. Running on batteries only, Voltage at...

FWI: I message SRNE service regarding a USB communications issue I had between the ASP and my PC, where once ever 30 to 60 minutes I would hear a relay click from the inverter and then my computer would ding indicating a disconnecting usb device... The disconnected device was the usb cable going...

Price includes shipping and one tax, btw...

Make sure to use rubber grommets on the new holes to make sure you don't short out the new cell and bms wire goint to it. The battery will weigh somwhere between 11 and 12 lbs so secure it properly or you may run into very dangerous situations if it falls or slips off. If you're unsure about...

I reread the manual and noticed that on page 19, point #5 it says: "communication cable for parallel operation is a DB15 standard computer cable with shielding function" That is to say, it's a standard shielded VGA extension cable for a computer, male on one end and female on the other.

My DIY 16s 280ah pack is currently setup with an ANT BMS that has active balancing built in and enabled. The balancing current is limmited to a maximum of 180 mA (0.18A). When I first connected all the cells together in series and started charging (no load connected), all was good until it...

I would assume that the employees are getting paid on a commission basis, thus some of them are greedy and others are less greedy, hence price differences for the same product in the same company.

It will work for our system in that mode as well. Inverter one is dedicated to L1 output at 10Kw and Inverter 2 is dedicated to L2 output at 10Kw. My only question regarding this mode is what happens when one inverter faults out but the other one doesn't? Do they both shutdown or does one keep...

I don't have a second ASP to test with and I'm sure 42OhmsPA wouldn't want to tear apart his setup and retest using the above setup....sigh...wish I was a multi-millionair some days, instead of struggling day to day...

That looks to be the correct conections for north america... Do you have an AC current clamp meter to see how much current is being output by the inverters? I could just be a software issue or wrong register being read for that value, possibly?? First, I'd try out the settings from 42OhmsPA...

That's a good habit to develop, turning off the loads before switching off main power source (but sometimes there is no choice in that). At 12 volts, that switch will be fine in your case then., good to know you're running a 12V system.

Only reason for me would be the ability to monitor, change settings and remote reset the systems no matter where in the world I happen to be. All from one device with secured remote login capability NOT written by nor designed by chinese and other companies that are prone to include special gift...

That looks more like severe overheating issue... now...biggest question is what caused those batteries to severely overheat???

List of only solar and inverter realated stuff I've bought from these companies that honor their warratnties (so far no problems): ANT BMS store - AliExpress Morden Store - ZK6522 DC-DC converter - AliExpress Snaterm Office Store - MC4 connectors and tools - AliExpress ATORCH Innovative...

Except for a couple of clear days, it's been nothing more then rain, thunderstorms and high winds for the last 3 weeks over here... sigh... makes it so hard to do anything outside when it's all mud and boggy everywhere I need to do some work. All I can say is stay safe out there while working...

Test the continuity of your db15 cables for parallel operation, one of them may be bad and the inverters can't talk properly to each other.

Yes, I remember those 2 posts well, but the above method would work as well since you are dedicating P1 to L1 and P2 to L2 outputs respectively. After that you have to change the settings as per pic below: Inverter one (P1): 31 2P0 38 120 68 IGNORE THIS SETTING Inverter two (P2): 31 2P2 38...

Also your settings video didn't show setting 56. setting 56 - leakage protection this possibly may cause surging in the genny as well

I have not tested this on my ASP (ASF should be the same) inverter yet, it's on my list of things yet to be done, hopefully within the next couple of weeks.
