Hi i just installed 8x200a batteries with jk bms, but im having trouble to get it to work with solar assistant. i have the ftdi adapter, but i cant get it to work, the manual of solar assistant doesnt help much, anybody know the trick? i have the dip switch according to the manual but thats it. Please help.

Hi, can you point me in the right direction for firmware update?? I allready power cycle the inverters and the problem remains, as soon as i have any solar production the inverters charge from the grid until a force them to go to SBU

Still with the same problem, i have tried everything, any ideas?? Thanks!

I found another strange thing, this happend only when solar is in play, today was a very cloudy day so i stay only in utility mode, and now at night the inverters respect the rule of 2amp each for 1-2, 3-4 no charge

The only thing i could find about timer for charger was setting 100. But the 4 inverters are the same, CSO,SNU,OSO at 00:00

Thanks a lot i will check the per hour problem. when i press the arrows on the inverter Says: U18206 U22221 U30000 Solar assistant says firmware 82.06 All the inverters are the same

Everyday this happend at 7:31 am, i cant get a workaround this

Hi i have 4 axpert max 10kw and these days they started acting strange. I have for inverter 1 and 2 , solar and utility and inverter 3 and 4 solar only, but around 7:30 am the inverters 3 and 4 start charging from utility with 15amps each i try everything i can think of, power cycle all the inverters and nothing, this started to happend after 2 days of power outage. I can seem to block the utility charge from inverter 3-4, before 7:30am works fine only inverter 1-2 charge with 2amp each. I have 8 batteries Pace BMS all connected to a busbar. Solar assistant and home assistant. All the inverters connected to solar assistant. Any ideas???? Also i have the 90v problem but there is no support to update the firmware here in Chile.

3 x 10kw inverters in parallel. A lot of solar panels, 6x100amp bat, 4 houses. Just starting but getting better every month, im waiting for six more batteries. All manage with automation throw home assistant, one irradiance sensor, a lot lot lot of hours hahaahaah, but im happy. Here en Chile is quite expensive these days.

Yes they are lithium 100Ah - 4.8Kw they are 4.8 Kw, at 0.2 i charge them just fine within the day, i have 16 x 550w and 28 x 585 solar panels installed, and 3 inverters ( this setup is to mantain 4 houses im not cooking meth ahhahaha )

Thanks!!!

Hi, everywhere says recommended max charging, but the lower you can is better??? I have 6 x 100amps, and i have 20k solar panels, its almost summer here so i have a lot of sun, im currently charging at 0.3 C, i know its safe but my questio is to better charge at 0.5 C? Or the lower the better??

That good!! Btw i have 6 packs connected to busbar and SOC also is not always the same, sometimes one have more than the other ones and sometimes less

Hi there! What a journey hahaha. A litlle advice, batteries should be stuck together, when charge/discharge is high they could produce some heat, check the temp values reported by the BMS, also i see cable lenght are not the same. Maybe is 25mm2? Right? Your inverter shouldnt draw more than a 100Amps, otherwize it will produce a lot of heat, for more than 2 or 3 batteries i would go directly to busbars. Just some advice! Nice clean install btw

Great! 35mm2 for 185 amps i think is a little to short, you could produce a lot of heat there. If the 185 are constant. I use 70mm2 for max of 200amp and works like a charm. you could try connecting like this: inverter + to master battery + to slave battery + inverter - to slave battery - to master battery - like the picture attached…. if in the future you are planning adding more batteries, i would go with busbar right away, you would need 2 busbar ( + - ) rated for the max discharge current you would use. inverter in the middle of both batteries. And just like someone told me, the effects are not instant, i could take several days to work correctly. also i cant see exactly by the pictures but check for any washer beneath the terminals. Also everything has to be thight.
