8kW 48V Dual MPPT Hybrid Solar Inverter with IP65 for Residential Solar Systems

8kW 48V Single Phase Hybrid Solar Inverter with Dual MPPT IP65

The 8kW 48V Single Phase Hybrid Solar Inverter with Dual MPPT IP65 is designed for residential solar systems that require more power for household loads while integrating PV generation, battery storage and AC supply within one system.

With 8000W rated AC output, up to 13.5kW PV input and 190A maximum charging current, this model provides more headroom for larger solar arrays and higher household energy demand than lower-power residential inverter systems.

Is an 8kW Hybrid Inverter Right for Your Home?

An 8kW inverter is generally considered when the electrical loads expected to operate at the same time exceed the practical range of smaller residential inverter systems.

Instead of sizing the inverter only from total daily electricity consumption, the important factor is the maximum simultaneous load. Air conditioners, water pumps, kitchen appliances and other higher-power equipment can significantly increase peak demand.

13.5kW PV Input for Larger Residential Solar Arrays

Although the inverter has an 8kW rated AC output, the PV section supports up to 13,500W of solar input. This provides greater flexibility when designing a solar system where the PV array rating is higher than the inverter's nominal AC output.

PV array design must also respect the electrical input limits. Maximum DC voltage is 520Vdc and the MPPT operating voltage range is 50–450Vdc.

Dual MPPT for Different Solar String Conditions

The 8kW model is equipped with two MPPT trackers. The parameter sheet specifies maximum PV input current as 18A + 36A across the two MPPT inputs.

Separate MPPT tracking can help installers configure PV strings for different roof orientations, module groups or solar array conditions without relying on a single tracking input.

The final number of panels in each string should be calculated from module Voc, Vmp and current specifications together with expected site temperature.

Solar, Battery and Grid Power in One System

The inverter supports grid-tied, off-grid and hybrid operating configurations, allowing solar generation, battery storage and AC supply to be coordinated according to the installation requirements.

48V Battery Platform with 190A Charging

The inverter uses a nominal 48Vdc battery architecture and specifies a maximum charging current of 190A. CAN and RS485 interfaces are provided for communication with compatible battery systems.

For 51.2V LiFePO4 batteries commonly sold as 48V-class energy storage batteries, compatibility should be confirmed from the exact battery voltage range, charging parameters and BMS communication protocol.

When Should You Choose 8kW Instead of 6kW?

The main difference is not simply the inverter number. The 8kW model provides higher AC output capacity, supports a larger PV array and offers higher battery charging current.

Compared with the 6kW model, the 8kW version increases rated output from 6000W to 8000W, maximum PV input from 9000W to 13500W and maximum charging current from 135A to 190A.

For homes with higher simultaneous electrical loads or plans for a larger solar array, the additional capacity can provide more flexibility. Final selection should still be based on the actual household load, PV design and battery system.

Parallel Expansion for Higher Power Requirements

The inverter series supports parallel operation of up to six units for single-phase supply. A three-unit configuration is also listed for three-phase supply.

Parallel system design should be confirmed according to the required total output power, phase arrangement and project electrical design.
