The Voltmeter VMGI-4KW-SP is an industrial-grade 4kW single-phase on-grid solar PV inverter designed to convert direct current (DC) from solar arrays into synchronized alternating current (AC) for immediate load consumption and grid feedback. Operating as a pure grid-tied unit, it lowers reliance on grid power by injecting solar energy directly into your electrical network during daylight hours.
Ideal for medium-to-large residential buildings, duplexes, commercial offices, and institutional facilities in Bangladesh, the VMGI-4KW-SP optimizes solar harvesting with wide MPPT tracking range. As electricity tariffs continue to rise, this inverter offers a dependable solution to reduce monthly power expenses while supporting net-metering standards.
High conversion efficiency (98.3% maximum, 97.9% European efficiency).
Wide MPPT voltage range (80V – 560V DC) for flexible solar array configurations.
Integrated DC switch and multi-layer surge protection (DC/AC Type III).
Real-time remote telemetry supporting RS-485, Wi-Fi, and 4G communication options.
Compact transformer-less design with IP65-rated environmental sealing for long-term outdoor mounting.
High Efficiency: Transformer-less power electronics architecture minimizes power loss during DC-to-AC power conversion.
Durable Construction: Heavy-duty IP65 enclosure guards internal components against dust accumulation, rain, and ambient thermal expansion.
Safety Protection: Built-in protection suite includes anti-islanding, insulation detection, overcurrent, overvoltage, and short-circuit shutdown mechanisms.
Energy Saving: Directly reduces daytime electricity grid consumption, accelerating the payback period of your solar investment.
Easy Maintenance: Solid-state circuitry with natural convection fan-less cooling ensures low maintenance and quiet operation.
Residential: Duplex houses, multi-story family homes, and residential rooftops.
Commercial: Retail storefronts, corporate offices, clinics, and customer service centers.
Industrial & Factories: Light industrial facilities, assembly units, and control rooms.
Office: Private and commercial office facilities looking to lower daytime utility expenses.
Project Installation: Institutional, governmental, and commercial net-metering rooftop PV installations across Bangladesh.
Reliability: Built with industrial-grade solid-state components designed for continuous daily operations.
Performance: High power conversion delivers consistent energy harvesting even under cloudy or low-irradiance conditions.
Cost Effectiveness: Significantly reduces monthly utility bill charges and optimizes daytime electricity costs.
After-Sales Value: Supported by Loopshop’s local technical assistance, warranty fulfillment, and customer guidance in Bangladesh.

Reduces Electricity Cost: Offsets expensive daytime grid electricity, generating savings on commercial and residential power bills.
Improves Operational Reliability: Pure sine wave grid synchronization delivers clean power output, protecting delicate electronics from power quality issues.
Saves Maintenance Cost: Transformer-less design with natural cooling minimizes moving mechanical parts and servicing expenses.
Suitable for Bangladesh Environment: IP65 enclosure and high operating temperature range resist heat, dust, and high humidity.
Installation must be executed by a certified electrical engineer or qualified solar installer.
Wall-mount vertically on a solid, non-combustible surface in a shaded, well-ventilated location protected from direct driving weather.
Confirm AC grid line voltage (230V nominal) and DC PV array polarity prior to energizing.
Connect dedicated protective grounding (earthing) to prevent electric shock hazards and floating potentials.
Periodically check the external cooling fins for dust or debris build-up; clear using a dry, soft brush.
Inspect AC/DC wiring connections annually to ensure terminals remain tightly torqued and free of corrosion.
Review performance logs via the mobile app or monitoring portal regularly to detect grid anomalies early.
Never open the inverter casing when AC grid power or DC PV arrays are active; dangerous internal voltage persists.
Switch off both the external AC circuit breaker and internal DC switch before conducting any servicing work.
Do not operate the unit with damaged cables or bypassed protective fuses.
