Hello, I need help to configure a Multiplus II 3000 with 2 Narada 48NPFC100 lithium batteries in a PV system with 2 SMA Sunny Boy 1.5 in an off-grid system. The system is working fine and charging the batteries until for some reason unknown to me, the Multiplus raise the frequency and shuts down the SMA inverters (also the electricity in the house) even when the batteries are not fully charged. My supplier in Chile for both Narada Batteries and Victron Multiplus doesn´t answer my queries and I don´t trust in the batteries and charger configuration (VEConfigure and ESS) that the supplier gave me earlier. If more info is needed please ask me for it. Any help will be very appreciated.
