Long - Duration 12kW 60kWh All In One Energy Storage System with Dual MPPT
High - Capacity Solar Storage for Extended Backup Projects
This 12kW 60kWh all in one energy storage system combines a pure sine wave inverter, four stackable battery modules, dual MPPT solar charging, dual AC output and WiFi monitoring in one coordinated platform.
The battery bank provides 61.44kWh of rated energy and approximately 55.3kWh of usable energy at 90% depth of discharge. It is designed for projects where backup duration is more important than simply increasing inverter power, including large villas, remote properties, farms, lodges and sites with home-office or communication loads.
The modular construction separates the 12kW inverter from the four battery modules, making transportation, site access and final positioning more manageable than handling one extremely heavy cabinet.
Key Benefits of the 12kW 60kWh Configuration
Longer Energy Reserve Approximately 55.3kWh of usable storage supports longer operation of selected circuits when solar or utility power is unavailable.
Four-Module Battery Layout Four 15.36kWh modules create the storage bank while keeping each battery section independently manageable during delivery and installation.
Dual AC Load Management Installers can separate priority loads from flexible circuits to protect stored energy during longer outages.
Multiple Charging Sources Solar panels, compatible utility input and a generator can support battery charging according to the selected operating strategy.
Dual MPPT Solar Recovery for a 60kWh Battery Bank
The solar charger supports up to 9kW with one MPPT configuration and up to 15kW with the dual MPPT configuration. Two tracking channels can be useful for separate roof areas or photovoltaic strings with different orientations.
A larger battery bank requires careful energy planning. The practical solar array should be selected according to daily consumption, local peak-sun hours, required battery-recovery time and whether utility or generator charging will also be available.
The two AC outputs can be used to keep refrigeration, lighting, security, communications and selected work equipment on a priority circuit. Pumps, air conditioners and other motor-driven loads require separate checks for running power and startup demand.
Capacity Planning Note: The 12kW inverter determines the maximum combined continuous output, while the 55.3kWh usable battery reserve determines operating duration. Both values should be assessed separately during system sizing.

12kW 60kWh All In One ESS FAQ
How is the 60kWh battery capacity configured?
The storage bank uses four 15.36kWh battery modules, providing 61.44kWh of rated energy and approximately 55.3kWh of usable energy at 90% depth of discharge.
Why pair a 60kWh battery with a 12kW inverter?
This configuration focuses on longer operating duration rather than unusually high instantaneous power. It suits projects with moderate loads that must operate for extended periods.
Can the full 15kW PV input be divided between two roof areas?
Dual MPPT supports separate photovoltaic strings, provided the final design follows the specified power, current, voltage and open-circuit-voltage limits.
Can a generator support loads while charging the battery?
This depends on generator capacity, active loads and the charging-current setting. The generator should be sized for the intended combined demand.
What installation preparation is required?
Prepare stable floor support, dry protected placement, ventilation, cable access and service clearance. Each battery module weighs approximately 119kg and requires suitable handling equipment.
