12kW 20kWh All In One Energy Storage System With 24kVA Surge Dual MPPT

12kW 20kWh All In One Energy Storage System with 24kVA Surge and Dual MPPT

Balanced Power and Storage for Solar Backup Projects

This 12kW 20kWh 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 20kWh of rated energy and approximately 18kWh of usable energy at 90% depth of discharge. It offers more backup reserve than the 15kWh configuration while remaining more compact than larger 30kWh or 60kWh systems.

With 12kW continuous output and 24kVA surge power, the system is suitable for villas, larger homes, home offices, small shops and generator-supported solar projects with compatible motor-driven loads.

Why Choose the 12kW and 20kWh Configuration

Dual MPPT Solar Charging and Generator Support

The solar charger supports up to 9kW of photovoltaic input with one MPPT or up to 15kW when both MPPT channels are used. Two tracking channels can support suitable solar strings installed on different roof sections or orientations.

Solar energy can supply compatible daytime loads and charge the battery. When solar production decreases, stored energy can support selected circuits according to the configured source and load priorities.

Compatible utility input or a generator can provide an additional charging source during poor weather or extended outages. Generator voltage, frequency and available power must be confirmed before commissioning.

Engineering and Installation Specifications

12kW 20kWh All In One ESS FAQ

Why choose 20kWh instead of a 15kWh battery system?

The 20kWh configuration provides additional operating time while retaining the same 12kW output platform. It suits customers who need more reserve without moving to a 30kWh system.

Does 24kVA surge mean the system can continuously supply 24kW?

No. Continuous output is 12kW. The 24kVA value represents short-duration starting headroom for compatible loads.

Can the two MPPT channels use different solar roof orientations?

Yes, suitable separate strings can be connected when each input remains within the specified voltage, current and power limits.

Does 18kWh of usable energy equal 18 hours of backup?

Not necessarily. Backup duration depends on the average active load, inverter efficiency, battery settings, temperature and available solar charging.

What preparation is required for the four battery modules?

The installation area should provide stable support, dry indoor placement, ventilation, cable access and suitable handling for four battery modules weighing approximately 45kg each.
