500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine. Start Isolation (SI) can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics. Engine Isolation (EI) can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output. Manual override knob provides an added level of safety allowing control with or without power and offering LOCKED OFF capability for servicing.
