March 23, 20215 yr Quote Slave battery not charging Hi Everyone. Here comes a totally new green one! We have an Axpert 8K48V installed with 2 Dyness 48V/75A LiFe batteries installed. The batteries are wired up in parallel. There are 4 solar panelsystem connected to the inverter to charge the batteries during daylight hours. Presently, the system works - the PV charges tte battery which run the load. At night the battery is on Bypass and Escom charges the battery The problem is - only ONE battery, the Master, is charged. The installer said that once the Master is fully charged, the Slave will start acceptin a charge. This is the 4th day since commissioning and the Slave still has not taken a charge. The in staller has been too busy to come by. Please Brainstrust, what needs to be done to get the Slave working? Awaiting anxiously for some guidance . Regards Sam the Ham
March 23, 20215 yr Hi Sam Does the batteries have a communication attached to them (a lan cable)for the BMS? If not the inverter has no control on each individual battery and should charge both of them at the same time. Edited March 23, 20215 yr by Peter Topp
