Will has a video about "series" battery connections. Might want to watch it.

Looking at your picture, is the battery wired from inverter to battery to battery or inverter to common bus bars to batteries?

And EG4, at the least the ones I have, (7) are horrible at SOC. Here is the current readings of 2 batteries: I am using open loop and an F(x) function (also called a characterizer, FGEN or, look-up table), to get a better SOC "guess". Here is all the batteries, (4 brands) average state of SOC...

Which battery model?

I have been using voltage settings, only, in the inverter (MPP) and the EG4 SOC has been useless. As it reads right now: No rhyme or reason. Compared to RUiUX: All batteries have the same 4/0 cable (length, crimps, etc.), from the main buss bar to the buss bar in the battery rack. Sungold...

I would take a bit of that bet. It is a money flow thing. IF and that is a big IF, someone would need to complain to the Texas AG, an investigation and then IF the AG said stop, they would stop, perhaps a small fine in the overall scheme of things.

That can be done without charging the card, a temporary charge, can be done; think gas pumps. Plus a bit of double speak, IMHO. "Allows us to verify the payment before the item is shipped..." What? Charging the card months in advance or the day before shipping accomplishes the same goals of "a...

When I placed a "pre-order" for a "chargeverter", my credit card was charged the same day I placed the order and the charger did not ship for a couple of months. I was a bit miffed when I saw the charge on the next CC statement. I knew it would not ship for a few months and I expected to be...

That was four years ago, things might have changed. Is that the exact battery you were considering?

Not Evil.

I do not.

#1 OK, I did not move the goal post; the issue changed from no back feed to a bit is OK and I opine that is not OK and gave additional reasons. #2 The issue is back feed, the source is not relevant. >What is "the expected direction" of AC? What? You think because AC cycles it does not have a...

LOL, narrow scope. The lineman does not know what or where the source of the power is coming from when the power is not coming from the expected direction. Seems to me no back feed is the goal and because the inverter(s) is not achieving the goal...rationalizing enters. What's the harm of a...

The lineman, I am certain, ARE concerned about the lineman. You can hate the "power companies" all you desire. Real people are working the lines and back feed is dangerous.

Not sure if you had the job as lineman you would have that opinion.

HA, part of the story. >There is no evidence to accuse us of not sending someone to pick up the battery, LOL, not sure how I would have "evidence" of someone (a carrier) NOT coming here to pick up the battery, and no proof you sent someone, because you did not. If you did send someone, FedEx...

So sad, nothing to do with spelling. "Accomplice" might have been a better choice.

Now, just like your "collegue", you are writing falsehoods.

#1 You did not issue a refund. The credit card company reversed the charge. You fought tooth and nail for me to keep the damaged battery. #2 You said you would send someone to pick up the battery. You never did. #3 I contacted you after the, alleged, courier to pick up the battery, did not show...

For me, a 48 volt system, with 4 brands of batteries and all SOC values are mostly not usable. Right now, 0651: Look at the voltages and range of SOC.

When I traveled in a motorhome, for 6 years, I always had several options, depending on where I was at and what carrier had service. One of the best deals was Visible. It only runs on Verizon networks. I used a Samsung 7 or 8 as a hotspot. Cost, $25 per month, unlimited data. If you have actual...

If you live far out in the country and reliable grid power is a problem, it is easy to justify.

OP said nothing about storage.

Hello, I traveled and lived in a diesel pusher for six years and some of the systems, like overhead lighting, were 12 VDC and connected batteries were required. The inverter/battery charger (Xantrex 3KW PSW) keep the batteries charged while on shore power. Other items like exhaust fans, smoke...

Hello, Long story short, I have a Cerrnss 48V 100AH damaged before or during shipment. The left side rack mount is bent a bit and the cells were smashed against a metal separator and into the BMS board. The left is the damaged (I moved the cells off the metal plate) and the right is a capture...

I am using that one and so far no problems.

Or the WGen5300sc.

Charge batteries when too many overcast/rainy days in a row. Really a stop gap. https://hmisys.com/SolarMain.jpg

Thanks for all the responses. After much reading/comparing/ponder I will be getting a small gasoline generator and figure out the gasoline storage. The small diesel offerings are few. Warranties when not near a service center have little value. I would have to pay for shipping for any warranty...

I have not found one, Do you have a link to one?

I have 6 with the rack When I purchased all was in stock, in US I see they have a warehouse in Germany. Not about the pre-order issue. As to making your own rack, sure you can, I did for 6 other batteries, a mixture of brands and sizes. Another option for 6 with a rack, is EG4, if they are...

I thought about it and looked around but, decided a dedicated engine/generator would be a better solution, for me.

Yes, I had an Onan 7000 (diesel) in a motorhome at one time and it worked without issue for years.

I have dyed diesel storage for the tractor.
