I was able to resolve my issue by putting a soft-start on the AC unit. It was overcurrent.

I am on the high power hard wired port.

Unfortunately I am on a hard wired port and the GFCI is internal circuits

Bud, thank you. Due to family obligations it may be a couple days before I can take measurements. I am an EE so , yes, I do have a proper volt meter and do understand the difference between growing and neutral, etc. my gut says it might be overload as you mentioned and could put a soft...

Wondering if anyone has any ideas. I am installing a lifePo4 battery system ( 12v/600ah) with a 3000w renogy inverter in our 5th wheel camper. At this point I have everything mostly installed and am testing. No issues running microwave, coffee maker, etc. While not critical I was hoping I...

Yes. All wires equal length to the buss bars this way everything charges/drains equally. I just got done paralleling 4, 12V batteries just like this.

I have been through this and this subject is as bad as politics. People have said it is fine, people say absolutely no as the electrolyte will not cover all the plates if mounted any other way than up, some say the case is to thin and will deform, some say you are fine anyway but upside down...

Buy JBD bms’s from Aliexpress. I am building the exact same setup only with 16 150a cells. Bought 4 120a jbd bms’s for under $60us each. Run the 4 packs in parallel. That will give me 480 amps output with I hope I will NEVER need . This allows me the ability to pull a pack out easily if...

Yes I know. I was responding to your comment that you paralleled overnight to top balance . If just overnight with 200ah cells you probably didn’t do much unless you were already at 98% charge…

I will second @wholybee . I am using 150ah cells and am on about 24 hrs now of parallel charging 4 batteries together to top balance. I started at 3.291v +/- .001v. The cells are now at 3.360 +/- .001 so I a getting closer but not there yet. That is with a cv/cc ps set at 3.65v/ 10a...

Blame your dealer not GD. Batteries get added at the dealer as part of prep not at the factory. I have a 303rls (Absorption fridge) and GD specifies a minimum of 1 group 27 for reflections . I believe any units with residential (compressor) fridges they specify a min of 2. On the...

I will certainly agree a typical household compression fridge is a more consistent and easy to use beast any day of the week.

I apologize if my statement may have implied that to you. Purely on electric usage from a battery (AC with inverter or DC) an absorption fridge running on gas where the 12v is for circuit control only will utilize the lowest amount of electrical usage of most any fridge out there. Does it...

Well I guess I just don’t have the same connections you do. A cheap 100ah battery will run you $500. Buy a name brand and it will be more like $800+. Solar panels run $1/watt +/- . An mppt controller $100. An inverter $150-$200. Now add a whole bunch of copper wire, fuses, circuit...

I do. Who wants to spend thousands of dollars on oversizing solar panels and huge costly LIO battery banks in an RV when a propane tank works great. I want to be efficient not be purely solar friendly and $ foolish.... There is NO such thing as a free lunch. (or free solar system for that...

As others have stated . Something is wrong there from my experience. Running just the fridge I would last a month + on a 20lb tank (4.5gal) and you are saying you went through 120lbs (28 gal) of propane. Granted my fridge is smaller at 12cu not 18 but...

Ok all, I have read through this thread and am very confused. Several of you including the OP'er state how much an energy hog absorption fridges are and how much power they draw. You then say how much better a standard "household" compressor fridge is. Are you attempting to run your...

I bought solar panels from HQST (which is a sister company of Renogy). Honestly, I believe many of the products are the same just branded HQST or Renogy). I had a broken panel. Email response was typically 24 hrs but replacement product took 3+ months due to everything coming form China...

Hi all, I have some Lishen 150ah cels on order to make 12v batteries. No where in the spec chest does it mention positioning/ mounting of the batteries. I have done searches to understand if mounting prismatic cels on their side is an issue and some say yes, others say no problem, and most...

Good catch.! @RiverCity Looks like you might not need the LCD panel to set the battery type..

Ok, here is the manual from the manufacturer (not HQST) https://www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-MC2420.pdf First off the per page 10 (or page 6 as you view the PDF) the first LED is charge state. If solid it is in bulk charge mode. 2nd LED gives state...

ok, basic math, assuming a bit of overhead and not running a battery from 100% to 0%. A 300 ah 12v battery will get you about 2 hrs run time on one AC unit if indeed 1500w ish. You want 6 hrs evening time and running the other things you mention you are at 4+ batteries assuming fully charged...

And that is your opinion.... I will stay with propane when not on shore power. Most (but not all) typical RV-propane style fridges work better on gas than electric from my observation.

well if it is indeed a BMS you purchased from Overkill (and not a JBD from China) Overkill 100% stands behind the unit and has an unconditional warranty. The overkill is an OEM jbd bms BUT they are based in Florida with US stock.

Hi All: Looking to put in 2 banks of 280AH/12V batteries in parallel each with their own 120a JBD/Overkill BMS. I know the batteries have a continuous and peak (short term) discharge rate, and my inverter had both continuous and peak load ratings. I can not find similar specs for the BMS...

The cells have studs that makes them taller.

Send Michael a private message . That is the fastest way and that way he can keep track of your specific message string. Just ordered some earlier this weekend from him. Note due to Chinese New Year holidays nothing is going out of China right now...

The size of the inverter is the MAX continuous draw not the normal draw. Plan for up to 20% loss with the inverter for cheaply made modified sine wave inverters. 15% for better quality pure sine wave inverters. You will never be able to run a 3000 or 5000w inverter full load off of the...

I ran a same model but changed it last year. It is commonly felt that WFCO are the radio shack (am I showing my age?) of charges out there. They work, they are generic, They don’t work great (IMHO) they don’t sense battery levels well, etc. I analyzed multiple chargers, boondocker...

55 amps is the max dc charge/ supply. not the AC rating. It is designed (and not greatly I will add IMHO) for lead acid batteries NOT lithium.

Correct. Your BMS should be based on constant usage need (read discharge rate on BMS) with ability to handle peaks of usage, NOT total usage over time that is capacity of your batteries ( in your case 540ah). If you never draw more than 1500watts at one point in time your BMS continuous...

Ok 2000 watts is a lot of power in a camper for continual usage unless it includes Inverter items also. As a reference I am putting qty2 280ah 12v batteries in my 5th wheel and will run my Microwave, coffee maker, wife’s hair dryer, tv, etc. just about everything in there less electric heater...
