Designed for remote Emergency Parallel battery switching & dual battery charging, via the engine charging system. Switch can be remotely activated by using a momentary rocker, toggle or push button switch from the helm. Also automatically combines batteries by sensing voltage. When the start battery reaches 13.7V the switch turns on, paralleling the house battery for combined charge. When the engine is turned off, and the combined voltage drops to 12.8V, the switch turns off, isolating the batteries. Rated for charging systems up to 500A.
