Introduction of 3MWh Energy Storage System With 1.5MW Solar Panels

3000 kwh = 3000 kilowatts/hours = 3000,000 watts/hours = 3MWh = 3Mega-watt/hours

This page is mainly about a 3MWh energy storage system combined with 1.5MW solar panel solutions for industrial and commercial (C&I) use.

PVMARS provide a full set BESS system with solar
What Solar Energy Types Will Be Popular in 2024?

PVMARS uses a 20-ft standard container high cabinet, equipped with a 3.35MWh capacity lithium iron phosphate battery. It also has a BMS system, PCS, fire protection system, air conditioning (HVAC) system, container and container auxiliary systems, etc.

The 3MWh energy storage system is very suitable for buildings, factories, towns, supermarkets, large homesteads, hotels, resorts, etc.

You can also power all daily or special electrical equipment: freezers, central air conditioners, testing instruments, medical machinery, lights, computers, and any equipment that requires electricity.

This system can help you achieve energy independence, getting off the diesel or utility grid and providing a free, green source of electricity for your life.

PVMARS’s 3MWh energy storage system will be assembled and tested in the production factory.

You only need to install solar panels and connect them to the electronic parts of the energy storage container to achieve off-grid living.

Features and advantages of a 3MWh energy storage system:

1) Multifunctional PCS (also known as hybrid inverters): can connect different power supplies – solar, wind turbines, diesel generators, and utility grids. Output port: Any type of power equipment.

2) Multiple working modes are available: battery priority, public utility grid power supply priority, solar power supply priority, etc.

3) Flexible expansion design: Each 3.35MWh energy storage system container can be connected in parallel to increase capacity.

4) Touch screen LCD: parameters can be adjusted according to actual conditions.

5) Quick conversion: If battery power is exhausted, the system switches to any power supply in 0.0001 seconds.

6) Remote monitoring: The PVMARS online platform can remotely monitor batteries, solar panels, and output and input parameters.

PVMARS’s 3MWh energy storage system (ESS) + 1.5MW solar energy is an off-grid microgrid solution.

Solar panels themselves cannot store a lot of electricity, so the system uses photovoltaic panels to generate electricity during the day.

It delivers power to your electrical equipment through the PCS and enables the ESS to store excess solar power.

At night, the ESS will release electricity and make the entire city shine.
