I have been slowly building my backup/off grid sometimes system for the past year. Right now I have 30Kwh LiFePO4 storage with another 30 coming in the next year as I assemble that battery. I have two SI 6048’s and I will likely grab a couple more from a friend that has two he won’t be using...

Does anyone know if there is any difference between a SI 6048-10 produced in 2013 or 2014 vs one manufactured in 2020 besides the firmware it was shipped with?

I'm interested in utilizing the SMA Sunny Boy Storage inverter for a battery bank. I understand that for example the LG Resu HV battery is actually a 48v bank with a DC-DC boost converter that is outputting 400v. I'm assuming that this converter is a bidirectional converter, which would then...

I have a LiFePO4 house bank on my boat that I am setting up with a REC-Active BMS. The BMS is working as it should, except for the fact that I can't seem to get the NO discharge relay (or any relay for that matter) to latch and supply voltage to the Precharge module and thus my main contactor...

Long time lurker, first time poster. I am finally ready to pull the trigger on some CALB 180ah cells. I don't have time to wait for cells to be shipped from China, so I need to get them in the US. I see that BatteryWarehouse on Aliexpress has US distribution, and that is a tempting option...
