Awesome, thank you. That worked.

Hi, Is there an inverter setting that can temporarily charge the batteries to max from the grid? I wish to prepare for load shedding by fully charging the battery.

Thanks guys for all your input. I am the end user and these settings were set by the installer. Agree, I have changed this to ShutDown = 43V, Low Bat = 45V, and Restart = 48V I will contact them. Apologies, I am on a learning path with this setup... I had a smaller system that was supplied with discrete cells and a BMS to make up the battery pack. I have just added to them for my bigger system. I will chat to my installer and show him this thread.

Thanks for responding. LBSA make intelligent BMS's with coms but I am not going to replace mine. I have done a lot of research of Lifepo4 SOC and you cannot base it on voltage alone as the voltage range from 40 to 100% is small (6 volts) on a 48V system. Even with a built in intelligent BMS it is only 20% accurate. I have sent a query to Sunsynk and will post their answer here. Thanks Mark.

Hi, I have just installed a 5kw unit that is connected to a custom (discrete LiFePO4 3.2V 120Ah cells) battery pack. The battery pack is 2 banks of 16 giving 240Ah, 51.2V and 12.3kWh. This is protected with two "LBSA BMS 120A 16S 48V" BMS's. This is a dumb battery with no RS485 or CAN coms. Question: What are the correct inverter battery settings to give more than just 0 or 100% for the SOC? I currently have the following configured as in attached images. The second image is my Solarman chart from yesterday with either 0 or 100% SOC. The first image is my battery voltage in Solarman. I also tried AGM % but this mode pulls power from the grid when it thinks the battery is 0%. Thanks Mark.
