uh a voltmeter?

Yea I don't know how anyone can recommend a product when its been replaced 3 times in a year.

I use a topdon, great quality(512x384). https://amzn.to/3FDg9c8 Works with phone, so you can send images or save images quickly, comes with a nice case as well

i think its overblown. I had a very very cheap generator that had one of the worse sine waves you ever saw. That ran a cheap air compressor for hundreds of hours. that air compressor never had a issue, had it for 15+ years. i also own a predator that has a very very nice waveform. I am not...

Just wanted to comment and say really appreciate the work being done here. would also like to see t fuse and mega. also some of the cheap anl fuses on amazon.

curious what other dumb settings are there if they are over the 3.65

"backfed" is charging, this shouldn't be a issue, check with a meter

we can all guess, unless you go buy a meter and give numbers, I'm going with tornadoes in texas causing your issue.

Pretty happy with this. I have had this PSU for years. This is a Server Grade PSU out of a HP Server its capable of 75 amps at 120v and 100 amps at 200/240v (not adjustable) it does require a modification to allow voltage up to 14.x stock it runs at around 12v these psu's use to be hundreds...

if its like my 7k, there is a screw under the fuel tank to adjust the speed/frequency, set it to 62 with no load on it.

why would you connect the neutral at all. connect l1 and l2, and the ground.

pretty sure most people using dc-dc chargers are because there is not an outlet nearby....

I'm confused victron makes a 48/12. what do you mean there are no good options? https://amzn.to/3zxi1k5

found them

wago 221 has a set of connectors that work with 10g. I have them literally in my hand. you can also get split bolts, but 10 gauge fits wire nuts as well, its not a big connection

I am not trying to get on you, but when you want a system to last 20 years, the cost of the labor to replace the units, even if you got new ones for free, will easily disappear this initial cost savings. The thought process is "they are close if it breaks" scares me. I buy things to work and...

you can wire shark the connection if you truly want to, but I have written apps for android, and this has been a thing for years, for bluetooth. its literally all over google, and the overkill bms app even talks about it.

batteries are not charged to full power due to shipping. although lower than normal, should be fine. put them on the charger, and catch some fish.

I buy a ton off ali. open a dispute with ALI, the sellers must get dinged pretty hard because they do everything in their power to have you remove it. Tell the seller you will open dispute if a significant reduction in price is not given.

yea your going to have to explain that a bit more, that wiring seems massively overkill. some large assumptions https://www.victronenergy.com/inverters-chargers/multiplus-ii-2x-120v this is what your using at max wattage 3000 watts thats 234 amps. divide that by 6 thats 40 amps, and your...

considering it looks like a small ups battery, they are clearly lying, based on the comments, your going to be disappointed.

give you the real health of the cell, and its discharge rate. compared to the others.

no offense But I see 4 bolts to flip the bms over to measure the voltage.not really a stretch to deal with this, unless your waiting for the warranty people

never saw someone trying to make something so "simple" so complicated.

Ups's typically charge to float voltages on cheap units. they use standby charge profiles. which means his unit would generally not get charged over 60%, I don't know if the larger units has stages, the cheap ones don't

on the Noco, did all the lights go out except for the green?, or were all of them on and the green blinking? On my noco 10 the green light has to be the only one lit, that means full charge. if all the lights are on its pumping full amperage. the icon's are kind of worthless. you need an amp...

if you can't see the wire, how do you know its 2gauge all the way? based on your voltage drop, I'm not sure this is the case you need to determine where this 6A load is, that's not normal, has nothing to do with old wiring (my rv is from 1999, and the wire is fine shape). you need your dc...

I used nord locks on a engine that kept loosing its crank case bolts even with red loctite, they are expensive and there are some limitations, so far though the engine hasn't let go again.

Top balancing is done by charging each individual cell, not all of them together. if your bms has balancing, make sure its active, it can take hours/days for it to get them equalized. by charging each cell individually, this will get you there considerably faster. you may cells of different...

people love the 80% rule that's a thing for commercial and critical loads., if you actually look up trip charts for breakers, almost all of them are rated at 100%. I have run circuits at close to 100% for several hours without issue.

that looks like a camera issue, its a pretty low res as well. none of my cables look like that, regardless of ac or dc

you can see the rupture of the cell in the second photo, the insulation in the photo is charred, not melted. I see nothing wrong with the lug itself, just got hot from the apparent fire.

pressure tanks are set, with no water in the tank. they also do nothing for the pump like stated. leave it alone till water is coming out. get an amp meter, that generator should grunt hard on the startup for that well.

or its because its a requirement for bluetooth and BLE, and is an android thing that has nothing to do with china.

2 different devices shown, and your missing almost 8 hours of graphs

Turn off the PV Breaker Turn off the Loads Breaker Turn off the battery breaker Remove the communications cable between the battery and the inverter. Turn on the battery breaker. When inverter powers up go to advanced battery type lead acid lead capacity 280 press set go to charge charge control...

i own 6. I run them dry then fire them up when I need them. it can be years. Never had a issue. I had a rv generator sit 7 years due to a issue. once the issue was fixed. fired up and ran for 20 hours without issue.

need a manual transfer switch, inverter one side generator other side, although if you inverter is a charge based unit, you can just put the generator on the ac input side of the inverter if it has one, and you wouldn't need a transfer switch for the inverter, and if you have batteries it would...

people will need to know what model inverters he currently has.

turning batteries different directions can make the polarity in series look correct. the 48v charger shows they were wired in series, looking at a parsun 6k unit, it also indicates 48v. there is 99.9 chance i am right, and enough chance to blow the motor if I am wrong. i strongly recommend...

each battery should have equal length to distributer

yes if it uses a compatible bms like a JBD

To be honest your confusing me. you applied a load of 124 amps. that's a discharge, so why would you expect it to cut out at 3c? thats a charge cutout, not a discharge cutout, they are different settings. on the 3rd attempt you were at 11c, I believe(don't quote me) the default low cut off for...

interesting that ac charge is unchecked, and its charging.

yea, apparently i was reading the data sheet, it speaks to it in the manuals

I would keep a single 12v agm/lifep04 in the system, and use a dc to dc charger from the 48v bank to the 12v agm to keep it charged. I would buy a portable li ion jump starter to deal with a dead generator battery, or if your talking the coach battery, then a simple solenoid override or a ACR...

how DIY you want to go...

doesn't li time drop to a lower voltage if not in use? is this that bms issue where people get confused until a load is present and the voltage goes back up?

LOL those generators do not output high voltage dc to the parallel ports.

generators generally are either 30 amp or 50 amp. what does your generlink plug look like, just make a pigtail.

To calculate the maximum battery size you can fully charge with your 10kW solar setup, follow these steps: ### 1. **Daily Energy Production**: - Your 10kW system, assuming optimal conditions, can produce approximately 10 kWh per hour at peak sun. If you get around 5 hours of peak sunlight...

at 100 mile trips, I would consider it, and maybe a boat sinking alarm if you fall asleep

is there a reason why your not just using a portable lithium jump pack, so much easier, and can be used with other vehicles

so for the dumb people, if you have the autoformer which gives you more balance, why would you ever switch back to the quattro neutrals?

as long as its above the bms cutoff limit its not an issue.

seems to be the default area where the bms manufactures have set balancing to begin, around 3.4v

so whats the difference between battery priority and pv charge priority. they seem identical.

to each their own. I find cash and checks a royal pain, my ccs autopay, and i get a documented breakdown of everything i bought, and i get a decent amount of cash back a year.

The only people who will see cycle limits will probably be robot mower. I own several. they go from 100-25-30% 3 times a day, but they use liion, so 5 years is about the expected limit

that unit is never going to balance, your charge voltage is too low. the second it stops charging the balancing will end since the voltage will drop. i have a similar jbd, it balances anytime the deviation goes over the delta. in overkill you will see the color go yellow on the Bal icons for...

I would really like to see some examples of all these burnt out alternators. It's an issue on boats I get that, but that's a different environment. do people have links to these burnt alternators. Wire size will regulate the amperage flow as well. I have been alternator charging for 30 years...

breakers provide protection for the wire nothing else. has literally nothing to do with the appliances. appliances need their own protection

link the charger, do not buy batteries on aliexpress. buy from 18650store.com

he has a generator that needs over 100a to start. a single agm/ Lifep04 on a dc-dc charger is incredibly simple will prolly last 10 years and much cheaper in the long run.

thanks Mike, i think its pointless for me. I'm looking at an RV, I will never hit these cycle counts. will prolly run 95-5 to be honest. even if i get 500 cycle It will prolly take me years. Jenny is talking to me in PM now, thanks everyone

Thanks for the quick response, how do you determine if you get the higher cycle count and weld studs? just ask her as well?

30 amps is 120v. 50 amp is a 240 connection just like the house (doesn't matter if there are no 240 loads in the actual trailer) the issue here is this was designed for a built in generator it is expecting to see 240v. 30-50 amp adapters do combine the l1 and l2 sides.The issue I have is if...

i have found aliexpress to be quicker then amazon some times i have no idea what connector they are using. something like this though...

can't you just charge it from the 7 pin and ignore it from the rest of the system?

a bench power supply is a 0% charger.

Will I will be back in Vegas next year, we are going to hike angel's landing out in Zion if your interested, hopefully we can win the lottery to get a permit. I will ping my girlfriend and see if she is doing another henderson offroad trip any time soon, you can catch a ride if your interested.

thats actually a good thing. high self discharge is a bad sign. not sure why you thought you would be able to pump a ton of ah into them. you need to cycle them like mentioned above.

i have a wood splitter on a very distant circuit, where my dual inverter generators could not start it, and this is on a 15 amp circuit. I threw a inrush meter on it, and this thing pulls 70 amps on startup and doesn't trip the breaker. Inverter generators weren't even close to getting it started.

lol buddy it took me 9 hours to make my first rectangle in cad. i will give you a youtube link if you want to learn

Does not do DC amperage, which is a big one here. Fluke is not needed for 99% of people, my calibrated unit, which work bought me, measure within 1% of every other meter I own. I like the UNI-T lines and Mastech for my inrush, with logging. most advanced I own is a 2 channel moosmeter, with...

this is a more thorough version. i started with this.

buy a dc PD charger and a 100w usbc to usbc cable

what kind of outlet? do not coil wire, it generates heat. bypass the dc panel, and see if you still have the same voltage drop by the way 12.2 is on the low side for lifep04, are your batteries charged?

Thanks GPT.

yes so did mine

get a thermal camera. I didn't realize how large your setup is. Its substantially easier to find problems. and you need a comparison point as well. if every connection everywhere is at this temperature. there is a good chance this is normal. I have been doing a ton of testing lately, and I am...

are you running a residential fridge? otherwise why not turn off overnight?

yea, your meter is hooked up wrong. black should be in COM. red should be in the port on the right. please retake the photo with the plugs in the right ports.

well considering the design guy doesn't know how to write the code. I'd say we are still dead in the water lol

flexibility for more than 1 device.

if you look 4 posts up i said check polarity. I am a bit shocked it read anything, also curious if the fuses are blown due to this.

there is generally another fuse for the other post as well. good call on the meter photo, I wouldn't have thought he would get a correct voltage (not polarity) in the totally wrong ports.

have you opened one? what makes it not "premium"?

shouldn't the inverters be throwing a low battery alarm if the wiring is insufficient?

FYI the difference between 14.4 and 14.6 in practical sense is almost negligible, and is right on the edge of over voltage. victron LI chargers from my understanding stop at 14.1. i guess the charger is working properly? you mentioned it couldn't get the bank up in another post

you have to solder resistors into 2 different area's

you need to just learn how to read it, I have boughten close to 200 items from them, which compared to amazon for the identical item generally results in a 70% savings.

you just need to upgrade the wiring like mentioned to the battery with a fuse, the rest of it is fine, the panel will still only pull what it originally was designed for. be careful though, if i remember in my 2000 rv, there were seperate posts for "clean" and "dirty power" i had to jump them...

ridiculous they are using red for negative.

if the inverter can't pull the amperage needed for the load, I would expect the alarm.

i'd buy the bms cable and charge them individually while cycling them a bit. i assume this doesn't have bluetooth so no idea if it will even balance. I think your going to have to get to the terminals and charge them individually. i think they are going to need a couple cycles to see if they...

yea i was just thinking a rotary switch to be honest, don't see the need for the mcu, turn a knob push a button etc.... but i get your example to control it, I am cheating with gpt to learn your i2c code for that chip referenced above.

shows he has no load yet a soc below 75%, I agree is the charger configured around 7A? if you put a load on the unit, does the wattage increase?
