I’m using a 25.6 V 280 Ah LiFePO4 battery. To display the SOC as a percentage, do I just need to enter the battery capacity as 280 Ah, or is there something else I need to configure? There’s another option called CHARGER in VEConfig — does that need to be configured as well?
If you are using lithium batteries, you should have an external BMS configured for the batteries.
Then the multiplus battery monitor can be turned off. This does not affect the low voltage disconnect or the charger voltage settings.
The multiplus is not too accurate at monitoring battery SOC as it cannot take into account any external dc loads or charging.
