What is a 3MWh solar energy storage system?

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.

Can a 3MWh energy storage system help you achieve energy independence?

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.
