I have a foxcloud F3600 inverter which requires a VOC per PV Line (it allows 2 lines) of 80 ~ 550V. One string I have is 8 panels giving plenty of voltage to operate, however my second string has a VOC of 40V per panel (80V in series), but in reality it gives just short of the 80V minimum to...

Really need some help... I am pretty worried about the safety of my system in its current state! I have an AIO inverter / charger from Epever (similar to Growatt), and am struggling to understand how to best connect the ground for the AC inputs and outputs of this system. Manual link There is...

Arrived today so wanted to share with you initial unboxing on this Battery Equalizer PLC-10 from Mazava Purchased from AliExpress for around $35, it looked to be exactly what I was looking for. I have 4x12V in a 2P 2S setup for 24v. I have matched batteries but purchased at a different time...

Is there a way I can use a VV PSU to charge a 12v LifePO4 battery, manually. Or should I steer away from this and only use a charge controller due to the different stages of charging? I was thinking could I replace the solar input of the CC with a PSU to emulate a solar panel and benefit from...

Can batteries (AGM) simply be connected in parallel and left to rest to balance themselves? I am awaiting a balancer to be delivered, and curretly have 4xAGM with mismatched voltages between 13-14Volts. Would like to be able to balance them just to ensure the charger does not over volt single...

I have recently installed a inverter / charger, which displays the SOC on the controller panel. What I have noticed, is when current is drawn from the inverter (in particular those with higher loads), the voltage at the battery drops significantly so my SOC can drop from 100% to 50% in a matter...

I have 2x 100Ah 12V in series for a 24v setup and have plugged into my Epever UP3000 AIO. The batteries are being charged in boost mode via the mains, which defaults to 14.4V (28.8V for my setup) I am however hearing faint bubbling / fizzing noises from both batteries when in this boost...

I am researching BMS's for an 8S x 304Ah EVE setup I am looking to build, and see that Jikong have a BMS / Balancer for 8S. I have seen the Off grid garage review, however was unaware they made one for 8S. Does anyone have experience with this for 8S? Only downside I can see is this charger...

Planning to order some LifePO4 cells from China but it will likely be months before they arrive. In the meantime looking to by some cheap lead acids just to get my solar setup up and running. Can I use any leisure battery, some of then are very cheap. Currently looking at 2 of these...

Sorry another Aili question, I am new to the scene and getting to grips with a portable solar setup before getting a full off grid, hence no inverter yet. I have a basic setup currently, solar panel > PWM charger -> battery -> USB-C adapter Have recently purchase the Aili shut, all working...

My inveter is rated for 2400W continuous and 3000W max via 230VAC / 50Hz (I am in the UK) I am looking for a breaker for the AC output, and the manual recommends a 20Amp, which makes sense although 16A maybe arguably better. Looking to buy this breaker...

Looking to connect a pair of Qcells 335W G9 Panels to my AIO Inverter / Charger. I will have 2x 335W in Series (Voc = 40.8V x2 = 81.6V / Current = 9.91A) I have some HQC4 Connectors for my panels , however would like a safe and easy termination of the panels at the charger side. What's the...

Looking to source some quality 3.2v cells for a DIY battery, but am based out of the UK do don't have access to local stores in the US, only direct ship from China. Doncan Technology looks to have good cells based on the forum thread however I cant access the US stores so have to rely on China...

Looking for a basic solar off grid setup, for a DIY project in the UK I have very limited space (2x2.4m) tiles roof (south facing) where I am planning to install. I am building my kit list and would welcome any feedback on what I plan to buy and any better options that may be out there...
