Configure battery

Step 1 - Select battery

On the configuration page, select your battery by consulting the table below.

SolarAssistant battery selection

Selection Description
Use inverter values The application will display battery values reported by the inverter.

If your inverter is connected to your battery via a BMS communication cable SolarAssistant will show metrics the inverter reads from your battery BMS. In this case you don't need a USB to battery cable unless you want more in depth metrics.

Voltronic inverters (Axpert, MPP Solar, Mecer, Kodak, etc.) that don't have a BMS communication cable will have a very inaccurate battery state of charge (SoC) with lithium batteries because they determine the SoC by voltage. 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. It's less accurate than a Victron BMS but much more accurate than the standard voltage based readings of an inverter.
