Eftakher Posted September 22 Share Posted September 22 I DIY a solar project at my home. I installed 14 320watt panels in two string. Where I am getting 280v per strings. And I have two lithium server rack batteries, both are 48v 100ah 5.1kwh batteries. Both batteries are connected with bms cable with inverter. the issue is my batteries are charging very slow. And I couldn’t figure it out why it’s charging slower. Can anyone help me maximise the charging current? please help, i am new to solar Quote Link to comment Share on other sites More sharing options...

zsde Posted September 23 Share Posted September 23 (edited) You don't say what Batteries you have and also whether the BMS is actually communicating with the Inverter. Which BMS Protocol did you select in Programme code 36? It seems that it's not communicating, as your Max charge current is set to 2A. At that rate a 100Ah battery would need at least 50 hours to charge. If you know that the BMS can communicate with the Inverter, then you should apply the correct protocol. If you don't have that info then you should rather use USE2 and set all your parameters as per the Battery label specs.
