Hopefully? Another 48vdc-240vac Toriod Inverter build.

This Hall Sensor also shuts the Inverter down if DC input is over current, much the same as the existing AC output over current trips. No waiting for a fuse to blow or a Circuit breaker to trip. Over current faults cause the big Contactor to the left of the Sensor to open the Battery feed to the inverter. [seen clearly on the last photo] That Contactor is part of the Automated Capacitor bank charge and inverter startup / shutdown functions. . Edited 2023-06-05 18:56 by KeepIS
