3kW 48V Solar Hybrid Inverter With Dual MPPT IP66 Outdoor Design

3kW 48V Hybrid Solar Inverter with Dual MPPT and IP66 Outdoor Design

Hybrid Solar Inverter for Self-Consumption and Home Backup

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.

Dual MPPT and Outdoor Project Advantages

PV String and Backup Load Planning

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.

3kW Hybrid Solar Inverter FAQ

Can a 4.5kW solar array be connected to this 3kW inverter?

Yes. The listed maximum photovoltaic input is 4.5kW, provided the voltage and current of both solar strings remain within the specified limits.

Can panels on two different roof orientations be connected?

The two independent MPPT trackers can support suitable separate strings installed on different roof areas or orientations.

Will the inverter provide power when the utility grid fails?

Selected circuits connected to the backup output can be supplied from the battery, subject to available battery energy and the 3kW output limit.

Can the IP66 inverter be installed outdoors?

Yes, when it is mounted according to the installation manual with suitable cable sealing, ventilation clearance and protection from avoidable heat exposure.

Can the system operate without exporting electricity?

Compatible CT or smart-meter control can support a self-consumption configuration. Final settings must follow the project design and local grid requirements.
