Looking at the EG4 3000EHV-48 Am I reading this correctly, that I'll need an array with at least a 120v open circuit voltage?

I'm looking for a minimal inverter. I need 240v split phase w/ neutral inverter (think whole house generator input). I only need to run lights, fridge, and small electronics, but I need to feed a 240v split phase panel. I only need to feed 1200-1500 watts max. What's the smallest split-phase...

I've never purchased a commercial LifePo4 battery, so I'm curious about cell drift. I've built several DIY packs. Some VERY diy, and recently a Sun Fun Kit with quality eve 280ah cells. I notice that no matter what balancing method used (actual proper top balance with all cells in parallel...

Ordered my SFK kit a day ago. 280ah cells, with their BMS and new V3 lid/spacer system. Once I receive the kit and start building it I will update the thread.

Just saw @Will Prowse teardown the EnjoyBoy battery and it was missing the low temp sensor just like many other cheap units. Is it possible the sensor they're using is built into the BMS? The JBD systems we use for DIY projects do have an internal sensor... maybe these do to?

Does a high quality "portable" type inverter exist? By portable I mean, not the growatt type wall mount units, but the kind you'd bolt under your truck seat or van. Giandel 2200 watt inverters seem highly recommended and are ~300 bucks... AIMS makes an industrial unit that's twice the...

I have a brand new 15 foot camper. Came with 2 lead batteries. I build a lifepo4 pack and put it in the rear compartment of the camper. I ran 2GA welding wire from the front of the camper where the main 100amp breaker is located and all the positive leads tie together for batteries, inverters...

In the next year I'll be building a new (small) home and will be off grid. I wanted to get a budget 48v battery system going to test the loads I'd need to run a low frequency growatt inverter... Battery hookup then had these cells on sale...

I was going to get an SOK 206ah battery for a camper... But then I came across sunfun kits, and for about the same price, I can build a 260ah battery (I have a spare JBD bms in the shop) I'd kind of prefer the larger cells, and to put my BMS to good use... and have bluetooth monitoring... I...

Saw this thread: https://diysolarforum.com/threads/lifepo4-addition-to-a-sla-house-battery.29109/ And found the host to the an interesting guy, and went down the rabbit hole on his channel. Aside from now wanting to live on a boat like Captain Ron, I saw his air conditioning video. () As I was...

I DIY'd a 400AH 12v LifePo4 to go into "Stubby Bob". I'll keep the battery in the rear, and need to run cables to the front where the main wiring hookups are. The unit has a 1000 watt inverter onboard. All of the factory battery wiring is 2GA to the inverter. I don't plan on ever running...

Need to run a pair of wires from the front to back of my camper (20 feet) Where is the best source to buy 2/0 wire?

I just got a little camper and plan on upgrading to LifePo4. I would still like it to charge, even if it's a little bit from the 7-pin trailer harness. Anyone use one of these Victron DC-DC chargers? https://www.amazon.com/gp/product/B07L6H8VKL/ref=ox_sc_act_title_1?smid=AERMGYAT5R869&th=1

Just got my first camper. It has a 190watt 24v panel and a clumsy Go Power control panel that leaves a lot to be desired. I have a Victron 75/15 w/ BT in my shop that not being used. Would I benefit swapping in the Victron?

I have two 50 watt Rengogy mono panels + Victron 75/15 MPPT controller. A year or two ago, I wired the panels up in series, stuck them in the sun and was collecting 95-97 watts. I put the panels away for a while.. I moved, built a new shop, life, etc. I have them out on a clear and sunny day...

The section for "Battery under voltage" should be cell count x cell UNDER-voltage trigger and UNDER-voltage release... right?

Working on my 400ah 12v pack. Will be using a JBD 150amp BMS. What other protection devices should I have on the system? Fuse? Battery disconnect? What's best practice?

I have 16x 100AH packs. Connected in 4P4S config - So I'll need to connect the P strings. I was planning on using 4GA welding wire. For this short run (less than a foot) will I have any issues? The math checks out but I am curious if the hive mind that is much smarter than me has any advice to...

I'm working on my first "real" battery pack. 400ah 12v pack. All of my experience is with small 5-25ah packs that I have always used a hobby charger to re-charge as they see limited use for a very specific task. The pack is together after being top balanced. I've got a small Daly bms...

I got a little Daly 60A "R05J-GF12" (https://www.ebay.com/itm/234060907591?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2648) I got the USB and Bluetooth dongle options. It's fully programmable (With the PC software) but it came with no instructions other than some hand drawn photocopy...

Looking for some quality 10ga wire (red/black) flexible stranded wire to use for connecting packs and chargers and such. Anyone have a quality item on Amazon they trust?

I've got 16x 100ah cells. Initially tried to parallel all of them and get them up to 3.6. I only had a dinky 5amp CCCV gadget and at 3.3v it was pushing ~2 amps. I imagine it would have taken a year to top balance at that rate. It ran for 48 hours and the voltage didn't move at all. So I broke...

I got 16x 100ah cells from Battery Hookup. I've got all 16 in parallel on a bus bar. I only have a 10amp CCCV power supply to top balance them up to 3.6. Am I doing any damage by charging them this slowly above their nominal voltage? It might take a week or more at this point. I'm new to...
