Description
The Voltmeter VMGI-25KW is a premium 25kW three-phase on-grid PV inverter built to convert high-voltage direct current (DC) generated by commercial solar arrays into clean, synchronized 400V alternating current (AC) for immediate facility usage and grid feedback. Operating as a pure grid-tied unit, it actively reduces dependence on main utility power during daylight hours.
Engineered for commercial buildings, manufacturing factories, textile mills, shopping complexes, and large-scale rooftop net-metering projects across Bangladesh, the VMGI-25KW optimizes energy yield through dual independent MPPT trackers. As commercial electricity tariffs rise, this 25kW inverter delivers a reliable, cost-reducing power solution while meeting local grid safety standards.

Installation & Maintenance Guide
Installation Requirements:
-
Must be installed by a certified electrical engineer or qualified commercial solar system installer.
-
Mount vertically on a solid, non-combustible wall surface in a well-ventilated location protected from direct driving rain.
-
Verify proper 400V three-phase AC line balance, neutral connection, and correct DC PV string polarity prior to energizing.
-
Establish a dedicated protective earthing ground connection to protect against electrical shock hazards and floating potential.
Maintenance Tips:
-
Periodically check external heatsinks and fan ventilation grilles for dust accumulation; clean using a dry, soft brush.
-
Inspect AC and DC wiring terminals annually to ensure connections remain securely torqued and free from corrosion.
-
Review diagnostic status via the LCD screen or mobile monitoring application regularly to detect grid anomalies early.
Safety Instructions:
-
Never open the unit casing while connected to active DC solar arrays or AC power lines; dangerous high voltage remains present internally.
-
Switch off both the external AC circuit breaker and internal DC isolator switch before carrying out any physical service work.
-
Do not bypass internal circuit protections or operate the inverter with damaged wiring.
