12kW Solar Inverter for 51.2V Batteries with 160A PV and AC Charging
This 12kW solar inverter is designed around a nominal 51.2V battery platform and supports compatible lithium and lead-acid batteries. It integrates photovoltaic charging, AC charging, pure sine wave output and multiple communication interfaces in one unit.
The maximum photovoltaic charge current is listed as 160A, while the maximum AC charge current is also 160A. When photovoltaic and AC charging are used together, the maximum combined charge current remains 160A rather than increasing to 320A.
This configuration is suitable for battery distributors, solar installers and system integrators requiring a higher-output inverter for compatible 51.2V battery banks and larger residential or small-business loads.
51.2V Battery Platform
The inverter operates with a nominal 51.2Vdc battery bank and requires correctly sized DC cables, protection devices and connection hardware.
Lithium and Lead-Acid Support
Compatible lithium or lead-acid batteries can be selected according to the required capacity, discharge rate and charging settings.
160A Photovoltaic Charging
The MPPT charger can provide up to the listed 160A limit when sufficient photovoltaic energy is available and the battery accepts the configured current.
160A AC Charging
Compatible AC input can supplement photovoltaic charging when solar production is insufficient or faster battery recovery is required.
The maximum inverter charging current should not automatically be applied to every battery bank. The selected value must remain within the battery manufacturer’s permitted charge rate, BMS limit, cable capacity and DC protection rating.
The formal parameter table lists a floating-charge voltage of 56V and an overcharge-protection voltage of 58.4V. Final settings must match the selected battery chemistry and the battery supplier’s technical instructions.
Battery energy capacity determines expected backup duration, while the inverter rating determines how much load can operate at one time. A larger battery bank can extend operating time but does not increase the 12kW continuous output.
The maximum combined photovoltaic and AC charging current is 160A. Charging priorities should be coordinated so that the total configured current does not exceed this value.

Battery type, capacity, charging voltage, current limit, cable size and protection devices must be confirmed before commissioning. This page does not replace the battery manufacturer’s installation instructions.
Yes. Both battery types are listed, but the charging voltage and current settings must match the selected battery system.
No. The maximum combined photovoltaic and AC charging current is listed as 160A.
No. Permitted charging current depends on battery capacity, chemistry, BMS rating, cable size and DC protection equipment.
The specification lists 56V for floating charge and 58.4V for overcharge protection. Final settings must follow the battery supplier’s requirements.
No. Photovoltaic and AC charging can be coordinated, but their combined maximum remains 160A.
This solar inverter is suitable for battery distributors, installers and system integrators requiring a high-output 51.2V platform with photovoltaic and AC charging.
