Industrial 5500VA Pure Sine Wave Output: Supplies clean, undistorted 220V AC electricity to safely run water pumps, deep freezers, commercial refrigerators, and medical equipment without motor strain or noise.
Rapid 15A Charging Circuitry: Delivers a continuous 15 Amp current for accelerated battery bank replenishment during brief mains windows, maintaining active charging even under severe 90V low-voltage conditions.
Phase-to-Phase & Back-Feed Safety: Outfitted with robust isolation circuitry that guards the inverter against incoming phase-to-phase overvoltage accidental feeds and dangerous back-feeding.
High-Efficiency 48V Architecture: Handles 70A ± 2A full-load discharge currents with minimal thermal resistance, lowering cable power losses across connected four-battery series arrays.
Battery Health & Discharge Management: Incorporates 54.8V float charging regulation and a calibrated 43.2V low-battery warning threshold to extend the working life of tubular, flat-plate, and SMF batteries.
