Converts Commercial Inverters into Solar Systems: High-voltage PWM retrofit controller upgrades standard non-solar heavy-duty inverters and HKVA UPS systems into intelligent solar backup setups, maximizing solar energy utilization.
Smart Auto-Detect High-Voltage Sensing: Available in dedicated high-voltage platforms (36V, 72V, 96V, and 120V DC) with intelligent battery sensing to ensure safe, multi-stage charging across Flat Plate, Tall Tubular, and SMF batteries.
Intelligent Grid Control for Maximum Savings: Automatically switches between solar and utility grid power to prioritize solar energy utilization whenever available, reducing mains power consumption and cutting commercial electricity bills.
Customizable 4-Level Depth of Discharge (DOD): Features four user-selectable discharge thresholds (20%, 30%, 40%, 50%) to prevent excessive battery depletion and prolong large battery bank lifespan.
User-Friendly Digital LCD & Complete Protection: Integrated digital display clearly indicates charging status, charging source, and battery type, backed by comprehensive protection against reverse PV, low battery, deep discharge, and over-temperature.
