January 30, 20251 yr Hi New to this forum but always have useful solar systems-related advice here. Hoping I will get the same in this particular issue. I am using a Solis S6-EH1P12K-L inverter connected to 2 HaiLei (or Solarpro) 300kWh 48V batteries in parallel. The Battery has a CAN Port with CANH H - Pin 4 & CAN L- PIN5. However, HaiLei batteries are not included in the Solis battery model selection. My specific question is regarding the correct DIP switch settings for both the Master and Slave batteries in this setup. With just one battery, the communication works fine using the DIP switch setting: ON OFF OFF OFF. I get Lithium Battery LV as Battery Type However, When I connect the second (slave) battery and set the DIP switch to OFF ON OFF OFF, the communication sometimes fails intermittently. The Battery Type in Battery Information Registers as 'NO Battery' Do you reckon I am getting the DIP Switches wrong on the slave battery? The battery manual has address 1 as on, off,off,off & address 2 as off on off off.
