VMHV1M3

500 kW / 1 MWh containerized hybrid energy storage system (VMHV1M3)

A containerized hybrid system combining solar PV, a 768 V LiFePO4 battery of up to 1 MWh and a 500 kW Perkins diesel generator, for mines, remote industrial sites, islands and large off-grid projects. With 1 MWh of stored energy and a 500 kW inverter, it starts and holds heavy motor loads - pumps, crushers, conveyors, workshop compressors - where a diesel genset alone would run at low load all night. With 1 MWh of stored energy and a 500 kW inverter it starts and holds heavy motor loads (pumps, crushers, conveyors, workshop compressors) where a diesel genset alone would run all night at low load.

Advantages

Why operators choose the VMHV1M3

Less fuel burned

Solar and battery supply the base load; diesel engages only when required.

Lower maintenance cost

Reduced diesel runtime extends service intervals.

On-demand diesel start

The EMS starts the generator only when needed.

Handles peak loads

Diesel and battery run in parallel for high peaks.

Works with your existing generator

Expansion mode for phased deployment.

4G monitoring as standard

Real-time data and alerts from anywhere.

Utility-scale hybrid power for remote sites

The VMHV1M3 is built for large off-grid and remote industrial projects that need reliable, scalable and fuel-efficient power. Solar and battery storage carry the load most of the day, and the Perkins generator is used only when needed. Delivered factory-direct from Chongqing, China.

FAQ

How much energy is stored in the VMHV1M3?

Up to 1 MWh of LiFePO4 storage at 768 V, built from a maximum of 20 modules. As an example, at a steady 250 kW load that is about 4 hours on battery alone before solar or the Perkins generator takes over.

Can it start heavy motor loads such as pumps, crushers or conveyors?

Yes. With a 500 kW inverter and 1 MWh of stored energy, it starts and holds heavy motor loads such as pumps, crushers, conveyors and compressors, and diesel and battery can run in parallel for high peaks instead of a genset running at low load all night.

How much solar can be connected?

The system has 4 MPPT channels with an MPPT range of 150 to 1,000 V, a maximum PV voltage of 1,100 V and up to 50 A per branch. The DC/DC stage reaches at least 99 % efficiency.

When does the diesel generator run?

Solar and the battery supply the base load, and the energy management system starts the 500 kW Perkins 1706J generator only when needed. Less diesel runtime means less fuel burned and longer service intervals; the genset has a 1,000 L tank and 75 dB(A) at 7 m.

How is it delivered and installed?

The system ships as one unit per 20 ft container, measuring 6,058 × 2,438 × 2,591 mm and weighing 15 t, FOB or CIF. AB-iPower provides installation assistance, and 4G monitoring and a router are included for remote follow-up.

What certifications and after-sales support do you offer?

Our products carry CE, IEC and UN38.3 certification. After delivery we provide installation assistance, and if a unit is defective AB-iPower covers transport and replaces the defective unit. You can also inspect the system at the factory or by live video before shipment.
