Well explained, I wasn't aware of the baud rate settings.

Hi Gary, I have a Solis hybrid 5KW inverter, 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!

Is there settings I may need to change if I add a second battery?

I have yet to add a second battery to my system. I will be doing this next month. Logic would tell me that the second battery would be set up just like the first battery in the BMS Studio, with the exception that the DIP switch setting would be different than the first battery. The total capacity should update on the inverter. In the event I find this to be inaccurate, I will update here. For now, this is what I have. Assuming you are adding batteries in parallel: On page 26 of the manual for the SEPLOS Vertical 280Ah Battery Pack, the DIP settings for a single battery will be all OFF. When adding a second battery, you need to set the first battery DIP to pin 5 ON. On the second battery, you need to set pin 1 ON. If adding a third battery, the setting for banks 1,2 and 3 are Pin 6 ON, Pin 1 On and Pin 2 ON with respect to each battery in that order. When adding a 4th battery bank, the DIP settings become slightly more complex. Up to 16 battery packs can be connected in parallel according to the manual. Please refer to the user manual for clarification, as the settings are only accurate at the time of this post and may also be misinterpreted.

We have a Solis 6kw hybrid inverter and a volt protection device before it. The device shows 2 amp import from grid but the inverter app shows that grid is not being used. What is the issue?

Small discrepancies seem to be commonplace between the inverter display and the APP. This is not just a Solis issue from what I have read. Like any electromechanical device, there will be a tolerance and this seems to be +/- 300W from my observations without detailed understanding or investigation. I hope that helps.

@@GaryMeatsLife the problem is that I haven't seen it 0 on the device even in peak sunlight hours. The device shows 2 to 3 amps. Could you please also mention what should be the CT direction and ratio and what is the criteria for setting this value?

@@wassaufkhalid8593I’ll pretext this by saying I’m a mechanical engineer and not an electrical engineer, so my understanding on this is limited and is gleaned from reading up on specialist contributions on online fora. The device will use a few amps and this may not be recorded in the APP output. Unless it is causing you to import/export unnecessarily, I would personally not worry about it. The inverter CT should point from the CU to the grid. I can’t advise on ratios. These settings are typically default values on the inverter and may only change when another relevant value is changed. The video is only intended for basic setup guidance. There are other channels which would cover settings on a deeper level. The solar DIY forum is also a great resource to troubleshoot. I’ve used it with good success.
