This makes the inverter suitable for running refrigerators, freezers, power tools, office equipment, lighting systems, and certain inductive devices within its rated capacity.
MPPT Solar Charge Controller Performance
At the heart of the inverter’s solar capability is its built-in 120A MPPT (Maximum Power Point Tracking) charge controller. MPPT technology ensures that solar panels operate at their optimal voltage and current levels, maximizing energy harvest throughout the day.
Solar Charging Specifications
| Solar Feature | Specification |
|---|---|
| MPPT Type | Built-in |
| MPPT Current | 120A |
| Max PV Input Power | 4200W |
| PV Input Voltage Range | 60V – 500V DC |
| Max PV Input Current | 16A |
The wide PV voltage range allows flexible solar array design, supporting both series and parallel panel configurations. This adaptability simplifies installation and improves performance in varying sunlight conditions.
AC Battery Charging Capability
In addition to solar charging, the inverter includes a powerful 100A AC battery charger. This allows batteries to be charged from the utility grid or generator when solar energy is insufficient.
AC Charging Benefits
