I wish I had your electric bill !

At the least run 4 conductors so it's easy to upgrade voltage later. I would do 240 the first time.

I'm still trying to figure out to build a car with no wheels, the Jetsons did it in the 60's and here I sit staring at my rubber tires. And they, like a battery with no bms tend to explode occasionally.

Try the Overkill Solar app.

I am using this one, of the 3 I tried including a Renogy, this one is fantastic for a cheap china's finest. Right now it is $159 Limited-time deal for Prime Members: OLTEANP 2024 New Upgraded 2200 Watts Pure Sine Wave Inverter, 12V DC to 110V AC Power Inverter with 4 AC Outlets, USB Port...

That's 41 years at 1 a day !

I have had ebay FOREVER !! used to sell a lot, now just make a few random purchases. 3 words to protect yourself and get your money back when needed...PAY WITH PAYPAL

Excuse the R/L error on the left main.

The $33 one is 8ah $145 for the 100ah

I have this in my RV to power all outlets when needed, what I found with this which I never intended an inverter to be used for is that it starts the 12k roof top a/c and will run upwards of 1800 watts without issue. The other 2 would immediately fault when the a/c was switched on. This is...

They also bill for time spent looking at their phones.

Get the correct length bolts, add LW's and FW's and call it a day. Buy extra washers if loosing them is your fear.

All good points. Re: Will, I watched him dissect batteries with an oscillating cutter on youtube...

Thanks, I did this;

2 chargers or 1 with dual independent outputs and a disconnect switch in the series leg between the batteries.

.

This one states heating function in the initial product info on the top of page but nowhere is it mentioned in the specs. If I bought one I would fully charge it then put it in freezer....then see what it REALLY has in it. If full of promises and nothing more, return it.

Can you access the wires upstream of the controller ? If so, splice in the new leads there and not try to gang them into the terminals on the control. They likely won't fit.

Good luck with Ali, what I have confirmed with my 3 purchases from them is the old adage, when something appears to good to be true it probably is. Or something like that. My 1st purchase was half of what was described, refund and they actually wanted it shipped back. 2nd was supposed to be a...

What app are you using ?

This is deep in the product detail info;

Yes, install a thru-wall plug if desired and connect the wires from the panel to the input of your controller along with the ones that are already there. Zamp Solar SAE Sidewall Port - Waterproof 10AWG SAE Power Socket Sidewall Port Quick Connect - RV Solar Ready, Battery Maintainer Hardwire...

So zero on trigger and leave release at -5c ?

The converter is only powered by A.C., Shore power.

Update... I swapped out the breaker with a replacement exchange of same one from same source, more for shits and giggles as to variation in build quality. This one carries a load of 1800 inverter watts but trips at 185 amps. Goes to show quality is all over the map. I am going to go with a...

This is an accurate drawing of the way this panel is built. The generator input breakers (2 pole each) will be installed directly below each of the mains with slide type physical interlocks. 6/4 romex to be used for input with 40 amp breakers.

Is it a 100ah or a 32ah ? This is why aliexpress always looks like bs to me;

What delta value would you recommend ?

I did exactly as you layout in point #1, also added a relay powered by the inverter to break power to the charger when the inverter is on. https://a.co/d/iF4sjOG

So zero and +5c ?

I hope your install looks less stetchy than the transport.

No

Truck frame to trailer frame is fine. Are your using an Anderson connector ?

I did this on mine;

I have a 200ah 12 Lifep04 with Bluetooth, I connected with the overkill app and saw that the total capacity is 160ah. Is this normal, should I rewrite it to a higher value or ? 

Correct, each main powers both legs (240) on that pair of bus bars.

My main panel has 2 main breakers, 1 feeding left breakers and the other feeding the right breakers. Is it possible to use one side for loads connected to a back up generator ( non bonded neutral ) and leave the other side powered by the grid or will 2 power sources make the utility neutral leg...

In my rv for the same reason as you I did a single 200ah with 200A bms and a 2200 watt inverter. This particular inverter will even start my Coleman mach 3 A.C., I experimented with 2 others including the renowned Renology that wouldn't come close to starting it. This one hardly blinks. And has...

After some contact and questions to them, the bluetooth information includes; * overall voltage * charge remaining percent * individual cell voltage * temp * difference between cells * real time amps charge and discharge * ah used and remaining * charge cycles * history tracking The touch screen...

This is the first time (already) that all cells are perfectly balanced, cell #3 was always slightly lower than the others, I just thought it was a little lame. Now it is in step.

I picked up one of these for 1799.00 on a Sam's sale, so far it is a real nice unit...

I can't answer that question. This is the charger I have, it is set for Lithum, that's all I can say...

So to confirm what I believe is true, if the input main on the right side (yellow 50 amp) is turned off and the gray 40 amp generator input is turned on, the branch circuits on that side can share the grid neutral as long as the generator neutral is not ground bonded. The left side branch...

So if it drains a true 160ah will the output turn off ?

Make up 2 extensions leads, hook it up to test, if it passes then strip away. If it fails, return it unscathed.

This is a strange one to me ... Lifepo4 200ah battery connected to a 2200 watt true sine wave inverter via a #1 awg cable, total cable length out and back is @8' with a 250 amp breaker located about 1' from the inverter, I know, should be close to the battery not the load....but, here's the...

Ya, I get that it is crap but lack of voltage drop with load, or tripping seem odd.

If I want to stay with a breaker, what brand is recommended ? Or, fuse it ?

No.

That drawing I made is only showing the hots, I have a pic I will find. Yes, U.S. as in Covina, CA. Original install from 1957 construction in L.A. County. Zinsco breakers.

.....or anything else.

I have a total of 400 watts on my rv and the highest amperage it has put out is 18.7 Panels I have done a short circuit amp check on always have come up short of the label spec. YMMV

So far shunt shows 198 ah used yet the bms shows 0 charge left at 11.5 volts.

For long storage they typically say 50% charge is recommended to avoid damage.

I have that same app for my battery and my soc is very accurate as compared with a shunt monitor. I think OP 's battery crapped the bed.

From experience I can state that a nice size 12 VDC model pulls @7amps when running, of course it doesn't run full time. That load is easy to manage when some solar a Lifep04 battery.

I did buy this battery, here is the cell voltage after full charge and balance completed. Is this good balance or ??

I had problems with breakers on my 2200 watt inverter, changed to a fuse and no more issues.

Thanks all, I will shunt test it and see what is real.

Do you have any 240v appliances / equipment on board ?

I am taking the leap to Lifep04 for my RV house bank, been digging through Amazon for the best feature bang for my shallow pockets. I don't have a shunt monitor as of now and if I had a bluetooth feature in the battery I don't think I would need to sweat having a shunt. Here it is, I would love...

Should the balance setting typically be set to while charging only ? Also, are the start and delta values typ ? See pic

You should leave 2 la or agm's in place, add an ACR, always leave the battery switch set to #1, keep #2 (it sounds like you leave the MBSS set to BOTH, never do that) in reserve for starting when needed, and add a cheap 200ah Lifep04 for the noise maker, dc-dc charger and shore charge as needed...

My bad, after looking closer that is a 50ah

I have cycled my new battery a few times to 60-70% discharge, yesterday I let it go all the way down to test the bms shut off point, it disconnected at 10.1 volts so that passed the test. My question is after a full discharge like this should it be recharged immediately to avoid any damage to...

That generator has the multi connector ats socket so unless to can crack the code to make it 2 wire start stop it probably won't serve you.

When I went from lead to Lifepo4 in my rv the smart charger I have only has lead and agm settings, I selected agm as the voltage output is higher. The bms in the battery shuts off the input once it hits full charge and finishes the balance.

I have been looking at this 6024, can it be used on 120vac input to charge a 12 8v Lifep04 ?

My battery just completed a charge and balance cycle from my 250 watt panel. Do these cell values look reasonable?

This is after sitting unused 12 hours.

Thanks for the replies, I had charged it at 40 amps previously which is the max output from my rv charger on shore power, while driving it charges at 14 amps through a DC-DC charger which also has a mppt input which I don't use at this point in time. I will keep it at @50% while not in use.

Just curious, if the 160ah value (post #1) was changed to 200ah would that make the display more accurate ?
