Rock on ??

I'm grounding my cabinet

Very true and I'm trying to make sure that they work as advertised.... I wasn't asking if they kept the batteries at 70F. If you read my post I say that I keep my batteries in my garage and I was just pointing out that I don't have to worry about that due to the 55F in my garage. The question...

I have an account with SS... send me a DM and lets roll

I'll DM you my email address and if you send an invoice I'll pay ASAP

EG4 just put out a new video and the configuration process seems to be the same as for the LL V2's... and you're right it will definitely be uncharted territory so I'll let you know when I know. Probably do a video on the results no matter if its positive or negative.

Not sure what this comment means?

Following, I would like to know as well

James I need your help with figuring out what is the specs on the Amphenol connectors used by the Power Pro batteries. I can't find answers in the manual and the parts have the manufacturers name Degson but no identafying numbers. Are they the 8mm or 8mm EMI amphenol connectors? I'm trying...

I'm definitely going to set my system up the same way. By the way I just submitted my diagram for my system for approval by Sol-Ark for warranty purposes and the tech guy said "I did forget to say this in the previous email, for EG4 batteries we don't support the communication. I know they say...

I’m trying to setup my Sol-Ark 15k with the APSmart RSD and I’d love to know what 12 volt external power supply people are using. I know the Sol-Ark can’t power it I contated APSmart and they admitted so but didn't offer an exact solution to the problem. I’m stuck… Attached are images of the...

I'm trying to setup my Apsmart RSD.... i got the outdoor kit with the transmitter and the power supply but I can't get the power supply to work with my two Sol-Ark 15k's in parallel. How did you setup the power supply on your system? Based on the power supply requirements in the manual and...

My bad I thought he was responding to my post that was just info that I thought should be shared. Carry on

If you're not supposed to ground the battery then whey does number six on page 4 of the manual say to make sure the battery and the rack are properly grounded. (see pic) Not to say you're wrong but if you are they should put better instructions in the manual. My batteries are LL V2's

When did you place your order and with what distributor? Signature Solar?

Definitely appreciate the offer for a quick phone conversation... I may take you up on that but I think I'm almost there. I understand that I would have to disconnect and re-connect to each USB connected source of information in the software, not a problem, I'm a nerd from way back. And I...

When did you place your order?

I'm about to have all of my equipment finally delivered to do my install and was wondering what current users are running grounds for 6 EG4 LL V2 batteries in a rack. In the videos I've seen so far I don't see ground wires connected to the grounding lug on each battery so I'm thinking they are...

Xackly ??

Your direct connection to your batteries (not the hub connecting to the splitter) from the Pi.... what are the settings you're using in SA to see the battery data? CAN Protocol in the battery tab?

That's the certification for UL9540A not UL9540 there is a difference. To pass inspection in some municipalities they may require UL9540 certification. https://www.altestore.com/blog/2022/09/what-to-know-about-ul-9540-and-energy-storage-systems/

Markus I’d love to believe there is no warranty issue using both PP and LL V2’s together but the manual says otherwise. And James also said that it’s an issue that needs to be worked out so coms will be functional between PP & LL batteries. See second bullet point under warning in PP manual...

I have a master bus bar in the trough under the two Sol-Arks and everything connect to the bus bar. Battery banks, two groups, the 3 Power Pro's, and the rack of 6 LLV2's. They are all in closed loop. The Chargeverter will soon be connected to the main bus bar as well. Currently its...

Thanks I had already watched that one.... great minds think alike

My electrician who is assisting in doing my grid and load connections for my 2 Sol-Ark 15k’s in parallel asked me how many amps will the two inverters draw from the grid if there is no PV coming in and charging batteries from the grid connections? For the question I will be charging a rack of 6...

So there are two cables required to do both updates? I have the cable that came with my batteries that I used with BMS tools. Is there another cable other than EG4 USB Read/Write Cable? https://signaturesolar.com/eg4-usb-read-write-cable/ I understand I need to do each one separate but...

Ok my fine forum folks I sent the same question to Signature Solar and they sent this reply “As long as the battery bank is connected to the inverter properly and the inverter is grounded properly, the batteries and the rack themselves do not need any grounding wires as it will all be grounded...

thats a great way to kill some grass 🤣

Easy solution found… connect the AC side of the power supply to L1 & L2 of the load terminal on my 15k and works perfect. Ran ground wire as well of course.

I have three EG4 Power Pro batteries and I always top balance my batteries prior to connecting. So I took a pair of battery cables from my PP batteries and added a 2/0 lug on the end without the Amphenol connector. I connected the Amphenol connector to a battery and then connected the 2/0 lug...

Here's a pic from Solar Assistant from todays activity. You can see the spikes in energy from the grid right after the BMS reported a drop in voltage. I have also posted the battery setting used in the inverter.

Thats what I figured

I've used 48v batteries to charge up my Delta Pro using these cables. https://www.amazon.com/gp/product/B0BB1X6991/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&th=1 https://us.ecoflow.com/collections/accessories/products/solar-charging-cable?variant=40337525375049 How do you plan to charge the...

So I use the same cable for both ports and based on the written docs it’s the same procedure for updating software as the Power Pro batteries as seen in the recent install and commission video recently released. FYI sometimes it may seem I’m asking a dumb question but most of the time I do it...

I’m about to update the firmware on my LL V2 batteries so they can communicate with the PowerPro batteries and I have a question. I’m following the instructions in the video from SS labeled EG4 PowerPro ESS EG4 18Kpv install and commissioning and they are connecting the RS485 cable to the CAN...

I've been curious about the Ruixu batteries and the 15k as far as coms... you're having no issues at all? Are you off grid or still tied to the grid? If you are tied to the grid are you selling back excess energy when available?

Zero, I’d like to see what weird output readings you’re getting on the load side? Are you splitting the battery com to use Solar Assistant? By the way I also have 6 LLV2 batteries connecting with the three Power Pros and they’re all talking to the Sol-Ark. it took updating the firmware on...

Theoretical question... I have 3 EG4 Power Pro batteries in parallel connected to two Sol-Ark 15k's in parallel and was wondering if in a emergency situation could I disconnect the batteries from my inverter, and connect the EG4 Chargeverter to the internal bus bar in one of the batteries to...

I like how it comes in a flight case. its portable. LOL

I've seen people talk about using the DB9 port on the sol-ark for SA and ditching the dongle but that make me wonder if a DB9 splitter could be used to connect both the dongle and SA via that port. I wonder if anyone has tried that before

My loads in my house will never reach 200amps even in a surge. I notices you posted a pic of you SA with battery info... didn't see the pack info like I've seen on SA videos see image. Heres a link to the video I got that screen shot from.

I’ve had 2 Delta Pros and 4 xtra batteries on rack for about a year to be my critical loads panel backup. I’ve decided to go to a whole home hybrid inverter system and would like to sell my ECOFLOW equipment Delta Pro’s $1800 plus actual shipping each Extra Batteries $800 plus actual...

Thanks James.... just looking for reassurance because the last thing I want to do is damage my investment. Keep up the good work brother.

I downloaded the firmware update for the LL-S firmware and I noticed that the read me text states that this firmware is only to be used on EG4 LL S (EG4 LL V4) batteries. Am I missing something? Also, I'd like to make sure I have the right firmware downloads. I'm assuming I have to do both...

So where is the other cable in Signatures website? I only see the RS232
