2500/month? how's huge is your home ? what're you running every sec ? where're you live ?

big and nice system how much total friend ?

Hello everyone, I have 17 solar panels, 9 of them running 3s and 3p, the other 8 are 4s and 2p total voltage is140v and 146v respectively real world measurement just around 115v - 125v since these # are less than 150v max that many cheap charger can support and safe to the touch if accident...

Hello all, I've been using homemade solar power since 2019 there're 8 people in the family, include 3 kids, 5 adults we're using/running all electric devices normally just like before, even more and more lately 4 fridges/freezers, 2 microwaves, 2 high power air fry/toaster oven, 2 hairdryers, 3...

seeing a baby on the cliff edge and turn a blind eye... seeing a poor set up and the lips are zipped.... is that you sir ? lol.....,

2k - 4k : 24v 4k and up : 48v

kindda load you got there when did you build your system ? good to hear it's still handle your needs well

that's exactly friend, 48 is way to go for the new build, unless impossible

way to go friend less demand. small system, make sense but others building a big, 5kw plus is another story

good to know it's time to up standard for RV's electrical system thx friend,

so why not 48 now, then to 72 or 96 if needed

So most RV folks got to stick with 12v with huge amp/cables to deal with ?

Greeting all, Noticing lots of people here still think about building a new/huge system @ 12 or 24v is it no debate that 48v is the only way to go ? it's everything better ! unless the new system is very small, sub 500w or upgrading from an even smaller one Am I missing anything ? happy...

that's pretty good

u not kidding, right ? meant 2219 ?

Hello every one, I've running off grid since 2019 bought 10kwh Batt from China for 3k, compare to 10 Grand here back then ( still running very strong ) keep expanding along the way..., now, the system are 17 panels x 390w = 6630 w and 3/48v Batt of total 20kwh today I observed the 2 charge...

48 is the only way to go when build a new system unless for a small, sub 500w

same thinking here need 1 more for 3x3

so you suggesting lower the charging voltage a bit more ?

Hello every one, My solar system is a bit overkill when Spring/summer coming the 3 batt of 20kwh total @ 48v will be full at around 1 Pm they're running in floating mode, at nearly 100% SOC, during the rest of the day, until 6 - 7 Pm it's 5 -6 hours long sitting at full every day nothing I can...

can we play around with BMS ? thought it's fixed by the manufacturer

thanks a lot for this info will closely keep that in mind, just in case good day

thx for the infos what's the damaged friend ? been running 4 years with no issues I thought it's good thx

extra room never hurt, right ? not so expensive too important, working good but it's ur choice friend

correct friend how to wire them 2 diff batt in parallel into the same inverter ? thx

agree and easy to do, for cheap but how to feed 2 diff batt into the same inverter friend ? best solution ? thx guys

MOES Dual Power Controller 50A 5500 Watt Automatic Transfer Switch for Off Grid Solar Wind System ATS DC 12V 24V 48V AC 110V 220V. been running for 4 years, no issues

add another charge controller into the system ? I think I can do that and not so expensive but letting the 2 different batt connecting to each other to the same inverter is the question how to make it happen friend ? thx

not an ideal to add another Inverter friend economically is no good better sacrifice the battery life

thank you so much for for input sir I will strongly reconsider my next move 1st step is down the charging voltage to 3.65 right away thanks again friend

15s vs 16s = 6.67% difference when I set the max charge voltage of the 16s at 3.5v or 56v per pack that 56v goes into the 15s, it become 56 : 15 = 3.73v 3.73v is a bit high than I would like, but as far as we know the max voltage for Lifepo4 batt to reach the dangerous level is 4.2 at 3.73, it...

wow, that job feel like an Engineer levels, can't imagine to try lol..., it's the Sungoldpower 48V 100AH SERVER RACK LIFEPO4 LITHIUM BATTERY SG48100P thanks

copy that not a good idea to mix them up been running 4 years on the 10kwh/15 cells but I got a super nice deal on the 16 cells and decided to add it up, then fix the issue later but it seem harder than I thought

Hello everyone, system with 2 battery ,one 10khw with 15 cells and the other 5kwh with 16 cells , 48v both sharing the same set up, in parallel. Problem is, the bigger one has lower voltage compare to the the smaller one, due to 1 cell less I be able to charge them up ok, but discharging cause...
