Evolution F Series 1200W, 120V Pure Sine Inverter/Charger with 12V Input , 60 Amp Charger with Hard WiringPure sine wave inverter/charger with 6 programmable charging profiles - 2, 3 and 4 stages with Equalization. For use with Lead Acid or Lithium Batteries. Samlex Evolution Series inverter/chargers provide reliable AC power wherever it's needed. For use with boats, RVs, cabins and specialty vehicles, as well as alternative energy, back-up and emergency power applications.Adaptive Battery Charger Option for Lead Acid Batteries6 programmable charging profiles - 2, 3 and 4 stages with EqualizationAlgorithm monitoring in the Bulk Stage assesses the battery's condition. The remaining charging stages are based on the battery's condition rather than a pre-set charging time.Reduces excess charging time and extends life of batteryTransfer SwitchZero transfer time when switching from Inverter to AC input source. When AC input source comes on, the inverter synchronizes with the incoming wave form and then transfers instantly at zero crossing without interruption to the load.Surge Capacity (Active Power Boost)The inverter has a surge capability of 3X its continuous power rating, allowing it to turn on loads with high starting surge.Inverter loads can exceed the continuous power output by the Power Boost Allowances without triggering and overload fault.There is no need to upsize to a larger inverter/charger to handle a heavy surge load, resulting in reduced costs.Solar InputConnect a so
