With no fumes, fuel or excess noise, it’s an excellent alternative to generator power.The DC-to-AC inverter features an automatic line-to-battery transfer switch and integrated charging system that allow it to work as a vehicle inverter, standalone AC power source or extended-run UPS. It delivers 3600W of continuous power, 5400W up to one hour or 7200W of peak power up to 10 seconds during equipment startup or cycling. An automatic overload detector, cooling fan and resettable AC circuit breakers protect the unit from damage.Designed for easy installation in RVs, commercial and fleet vehicles, emergency vehicles and construction equipment, the APSINT3636VR converts stored power from any 36V battery or automotive DC source to safe, stable, computer-grade AC power for unlimited runtime. When hardwired to an external 230V AC source, the unit keeps the user-supplied battery charged via a three-stage 7.5/30A selectable charging system while simultaneously delivering AC power to connected equipment.When used as a UPS, the APSINT3636VR’s automatic voltage regulation feature protects your equipment against blackouts, brownouts, surges and line noise. The APSRM4 module with “traffic light” LEDs is included to provide complete remote monitoring and control of the unit.
