I've had this for a couple weeks now and it's been great. I've been averaging about 25kwh per day from ~7k in solar panels. This is mostly limited by the zero export (300w buffer). For the house loads, the AC and dryer seem to be the biggest loads. When AC is running I pull about 4kw and...

I'm building a 12v 4 cell 280ah battery. I got the cells and BMS from Jenny Wu. I have it all wired up but the BMS doesn't seem to be operating correctly(or at all). It's a JK-B2A8S20P. I've followed the wiring instructions but I can't connect to bluetooth and it isn't taking/giving...

I'd like to build a solar system to offset my grid usage. There is a company local to me that is selling a large number of JA Solar 315w panels for $50 each. I'd like to build out a system to offset my grid usage. Currently I have a 900w setup, using the same panels, at my farm stand that I...

I'm looking to offset my energy usage with solar. I'm looking at a diy system using a Fronius string inverter and then later adding a hybrid with a battery as funds allow. I'm trying to figure out my best option for where to tie into my electrical system. I have a 320A meter base that is...

I recently put together a 16s DIY battery using MB31 cells and a JK-PB2A16S20P BMS. I'm attempting to get it to communicate with my Midnite 12K AIO. It is connected to the CAN port on the inverter and to the CAN port on the BMS/Battery. Right now I have it connected using a standard ethernet...

I built two 12v battery packs using 280ah cells and a JK BMS (JK B2A8S20P). They were both working well then one would not charge/discharge. I assumed I had a bad BMS after I cycled the BMS and tried emergency mode and still no charge/discharge. I replaced the BMS and I'm still getting the...
