The Solis S6-EH3P20K-H is a 20KW three-phase true hybrid solar inverter engineered to unify solar photovoltaic generation, energy storage, and AC utility interaction into a unified power system. It converts variable direct current (DC) harvested from solar arrays into clean, synchronized alternating current (AC) for local consumption, while directing surplus energy to high-voltage battery banks or exporting it back to the grid.
In Bangladesh, commercial operations and large residences face high grid electricity tariffs, voltage fluctuations, and recurring load shedding. The S6-EH3P20K-H solves these challenges through automatic energy dispatching: it prioritizes solar generation for active loads during peak sunlight, charges batteries with surplus power, and transitions to backup storage within 10 milliseconds during outages. This seamless operation prevents downtime for sensitive equipment, industrial machinery, and centralized air conditioning setups.
