September 28, 20232 yr Hi There, I recently added solar assistant to my setup and it has raised some concerns, can I please get some help for the settings. The inverter switches of the solar when the batteries are at 97% state of charge and switches back to solar when dropped by 1%. How can I get the batteries to charge 100% and then have solar run the load until solar is unable to manage the load? The inverter keeps updating the settings to 140A, If i understand correctly, the batteries should never be charged higher than 20A per battery, so no more than 80A. Am I correct or what is the correct A for 4x US3000C 3.5KW Pylontech Batteries or is 140A safe for the longevity of the battery? My setup:- 1x Kodak King 5kw, 4x 3.5kw Pylontech Batteries, 6x 660w Canadian Solar Panels 125A Battery Fuse, 50A Solar Fuse Battery recharge from grid at 20% SOC, Inverter shutdown at 10% SOC Shut Down Battery 46v, To grid 48v, Back to Battery 49v, Battery float and absorption charge 53.2v Max charge 140A, Max grid charge 10A Any assistance is greatly appreciated and happy to supply additional information if needed. Thank you.

Thank you. Are you using 3 parallel strings and do you have fuses for each string or only the 50A fuses between panels and the inverter?
September 28, 20232 yr Author I believe we are using 2 parallel strings and the 50A fuse is between the panels and the inverter
September 28, 20232 yr Author I purchased Solar Assistant and through that interface I managed to find the right settings. After much playing around on Solar Assistant, I managed to resolve the issue. Solar Assistant which was such a huge help in correcting my issue. Basically i changed the following:- Battery from Inverter settings to Emulated BMS I had both the Micro USB from inverter to Solar Assistant and Voltronic RS232 from inverter to Solar Assistant. I removed the RS232. Current Connection:- Pylontech Cable from Master Battery to Inverter Micro USB from inverter to Solar Assistant Changes Experienced:- Battery now shows 100% charge and not 97% at full Solar remains on to manage the load after battery has fully charged No more fault 69 or error 61 with current set up show below Battery charges from the grid at 20%, and not at a voltage spike Max current max charge current of 50A from solar, 10A from grid Some screen grabs of my setting for Solar Assistant if needed, hope this helps others with similar issues
