The inrush current when switching on the battery breaker onto the DC bus is huge. This can cause damage to the breaker over time. So it is a Freedom Won requirement that the DC bus is pre-charged before switching on the battery. This is achieved by switching on the AC input to the inverters – the inverters will use the AC power to pre-charge their capacitors. This will eliminate the huge inrush current. The MPPTs can also be used for pre-charging by switching on the solar panels supply to the MPPTs. | The inrush current when switching on the battery breaker onto the DC bus is huge.
