@HalfAJob worth checking the DC bus voltage target in the Solis parameters. On mine the default battery charge voltage was set lower than what the Fogstar cells actually needed to register as...

@GemmaStewart raises a good point on the CT clamp, but worth also checking your ESS assistant configuration if you're running one — specifically whether the "grid setpoint" is set...

The Drift's BMS is genuinely solid—been monitoring mine in the garden office for two years now and the cell variance stays within 20mV across the pack.

The inverter's your limiting factor here, not the batteries. Most diesel heaters pull 8-15A on the glow plug startup — that's fine.
