Inverter hanging plate installa�on 3.3 Ba�ery connec�on For safe opera�on and compliance, a separate DC over-current protector or disconnect device is required between the ba�ery and the inverter. In some applica�ons, switching devices may not be required but over-current protectors are s�ll required. Refer to the typical amperage in the table below for the required fuse or circuit breaker size.
