| High Light | 12kW Hybrid Solar Inverter ，48V Solar Inverter ，Dual MPPT Hybrid Inverter | ||
The 12kW 48V Single Phase Hybrid Solar Inverter with Dual MPPT IP65 is designed for single-phase solar systems that require higher AC output while combining photovoltaic generation, battery storage and AC power within one inverter platform.
It provides 12000W rated output, supports up to 16200W of PV input and offers up to 250A maximum battery charging current. Grid-tied, off-grid and hybrid operating specifications provide flexibility for different solar and backup system designs.
The main reason to move to a 12kW inverter is greater AC output capacity. The inverter provides 12000W rated output with a nominal output current of 52.2A.
For system sizing, the inverter should be selected according to the loads that may operate at the same time. Daily electricity consumption alone does not determine the required inverter power.
Maximum PV input power is specified at 16200W. Maximum DC voltage is 520Vdc, while the MPPT operating voltage range is 50–450Vdc.
The 12kW model uses two MPPT trackers, with the parameter sheet listing maximum PV input current as 18A + 36A across the MPPT inputs.
Solar panel quantity should be calculated from module Voc, Vmp and current rather than PV wattage alone.
The battery section specifies a nominal DC voltage of 48Vdc and maximum charging current of 250A. Maximum charging power is listed at 12000W.
CAN and RS485 interfaces are available for compatible battery communication. When using a 51.2V LiFePO4 battery, the exact operating voltage range, charging parameters and BMS communication protocol should be confirmed before installation.
The technical specification provides operating parameters for grid-tied, off-grid and hybrid configurations.

Choosing between the 10kW and 12kW models should primarily depend on required AC output and battery charging requirements.
Rated output: 10000W
Maximum PV input: 16200W
Maximum charging current: 220A
Rated output: 12000W
Maximum PV input: 16200W
Maximum charging current: 250A
Both models have the same specified maximum PV input power of 16.2kW. The 12kW version therefore mainly provides additional AC output capacity and higher maximum charging current rather than a larger PV input limit.
If the planned PV array is similar but the site requires greater simultaneous AC load capacity, the 12kW version may be the more appropriate option. Final selection should still be based on the complete load and battery configuration.
The inverter series supports up to six units for single-phase parallel operation. The specification also lists three units for a three-phase supply configuration.
Parallel operation should be designed according to required total power, phase arrangement and the electrical architecture of the project.
It can be suitable for a single-phase system with relatively high simultaneous electrical demand, but inverter sizing should be based on the actual loads that may operate at the same time. The inverter provides 12000W rated output.
The technical specification allows up to 16.2kW of PV input. The final solar array must also remain within the 520V maximum DC voltage, 50–450V MPPT range and specified PV input current limits.
A 16kW PV array is below the specified 16.2kW maximum PV input power. However, the solar string voltage and current must also be checked before confirming the final panel configuration.
The 12kW model provides 2kW more rated AC output and a higher maximum charging current of 250A, while both models have the same specified maximum PV input of 16.2kW. The decision should therefore focus mainly on load demand and battery system requirements.
The inverter uses a nominal 48Vdc battery architecture. Battery capacity should be selected according to required backup duration, while the battery system must also have suitable charging, current and communication characteristics for the inverter.
51.2V LiFePO4 batteries are commonly used in 48V-class energy storage systems. The exact battery voltage range, charging settings and CAN or RS485 communication protocol should still be checked before confirming compatibility.
Yes. The supplied technical specification includes off-grid operation and pure sine wave battery-mode output. Actual off-grid capability depends on the connected PV array, battery system and electrical loads.
Yes. The inverter series supports up to six units for single-phase parallel operation and lists a three-unit configuration for three-phase supply. Final parallel system design should be confirmed before installation.
