Hi every one , my system finished on 11/2019 , with the following : 375w x 9 solar panel ( 3 more panel added last year , now 375 x 12 = 4500w ) 10khw/48v Meritsun Lifepo4 battery pack ( bought from China ) Midnite classic 150 charge controller 7000w/48v/120v Reliable...

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...

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...

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...

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 every one, Just finished my 48V off grid system , so far so good, the only thing I'm not sure is that , the battery looks like still taking charge after it hit 100% full Anyone ever been thru this situation ? Thank you so much for all your help. Attached is the BMS screen shot

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...

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...
