I have a Growatt SPF5k inverter with two Lifepo4 batteries, each controlled by it''s own BMS (JK 100A). I there a way to connect both BMS''s to Solar Assistant? Currently it''s only one connected via RS485 dongle and the details aren''t accurate (-50%).

Configuring your battery in SolarAssistant

We recommend using a battery BMS cable or the Emulated BMS. Emulated BMS: Let SolarAssistant perform it''s own state of charge (SoC) calculation by counting power flowing in and out of the battery. This is a good fallback option for anyone who can''t get a real BMS reading.
