3kW 48V Hybrid Solar Inverter with Dual MPPT and IP66 Outdoor Design
This 3kW 48V hybrid solar inverter combines grid-connected solar operation, battery storage and a dedicated backup output in one compact system. It is designed for homes, apartments, small offices and other sites that want to use more rooftop solar energy while maintaining selected loads during a utility interruption.
The on-grid AC output is rated at 3kW, while the backup output also provides up to 3kW for compatible priority circuits. A transfer time of less than 20ms helps the system change to backup operation when the grid supply is unavailable.
Two independent MPPT trackers allow suitable photovoltaic strings to be arranged on different roof sections or orientations. This makes the inverter practical for residential roofs where panel direction, shading or available installation space may vary.
4.5kW Solar Array Support
The inverter accepts up to 4.5kW of photovoltaic input for daytime load supply and battery charging within the approved electrical limits.
Two Independent MPPT Trackers
Each MPPT input supports one suitable solar string with a listed input-current limit of 19A.
Dedicated Backup Output
Essential lighting, refrigeration, routers, security equipment and selected office devices can be placed on the backup circuit.
IP66 Enclosure
The enclosure supports protected outdoor installation when cable glands, clearances and mounting requirements are correctly followed.
The MPPT operating range is 80–520Vdc, with a 90Vdc startup voltage and a 550Vdc maximum photovoltaic open-circuit voltage. The full-power MPPT range for this 3kW version is listed as 117–500Vdc.
Each MPPT input is rated for up to 19A, with a listed short-circuit-current limit of 25A. Solar string design should therefore consider panel operating voltage, open-circuit voltage, current and cold-weather voltage rise.
The backup output should be connected to selected priority circuits rather than every electrical load in the building. Appliances with motors or compressors must be checked for startup demand and overload requirements.
Battery capacity determines the expected backup duration. The inverter’s 3kW output rating determines how much compatible equipment can operate at the same time.

This hybrid solar inverter can be configured for grid-connected self-consumption and backup operation. This page does not claim electricity selling or unrestricted power export to the utility grid.
Yes. The listed maximum photovoltaic input is 4.5kW, provided the voltage and current of both solar strings remain within the specified limits.
The two independent MPPT trackers can support suitable separate strings installed on different roof areas or orientations.
Selected circuits connected to the backup output can be supplied from the battery, subject to available battery energy and the 3kW output limit.
Yes, when it is mounted according to the installation manual with suitable cable sealing, ventilation clearance and protection from avoidable heat exposure.
Compatible CT or smart-meter control can support a self-consumption configuration. Final settings must follow the project design and local grid requirements.
This 3kW 48V hybrid solar inverter is suitable for distributors, residential solar installers and system integrators requiring dual MPPT input, battery backup and protected outdoor installation.
