This is how to connect your battery to your Solis Hybrid inverter. Battery used in video is Seplos Vertical 280L with 305Ah LiFePo4 Cells (48V) 16kWh. For Settings, see my other video • Solis Inverter Battery...

Make sure your Torque thoes battery connections (see installation manual for correct settings). Great video, thanks.

Hi Gary, I have the same inverter as you, and I'm using it with 16 EVE 304 cells and a JK inverter BMS with an active balancer. I've been running this setup for the past five months. The JK BMS communicates the state of charge (SOC) to the inverter, but the SOC keeps drifting over time. Here's the issue: even when the BMS indicates a 100% SOC, the voltages drift slightly lower with each cycle. Over the weeks, the SOC gradually drifts, so while it shows 100%, each cell and the overall pack voltage are slightly lower than the previous cycle. If I adjust the battery capacity settings, the BMS resets to 70% SOC, and the inverter charges another 3 or 4 kWh. This SOC drift is frustrating because on cloudy days, my 16 kWh battery effectively only charges to 11 or 12 kWh. The remaining 4 kWh stays uncharged because the BMS incorrectly reports 100% SOC to the inverter. To fully charge the battery, I have to keep changing the capacity settings in the BMS back and forth. Is there a way to use this inverter without CAN communication or by setting it as a generic battery? If anyone else has the same issue or knows a solution, please comment and suggest how to fix this problem. Thanks!

I'm only somewhat familiar with my setup, so can't comment much on the JK BMS. I don't know what active balancer you have, or what triggers it. I intend to hit the balance button on my battery pack at least one per month to help keep the voltages more closely aligned. With your 16kWh capacity, you'll only have 13-13.5kWh really available if you have set the max charge and discharge voltages to 10 and 90%. My discharge is set to 85% with forced charging at 90% depleted. As far as I know, you need to use the CAN between the battery and the inverter. The generic battery setting on the Solis is "user defined". This is actually what I am using and I have an updated video on the settings I will be releasing in the next 48 hours. You can check out the first settings video I already have uploaded and that might help you out. You might also check you are using the correct settings on the BMS for whatever battery chemistry/type you are using. Again, i'm not familiar with JK, so you would have to look more into that yourself.
