Clean Backup Power

GMDE energy storage system enables you to participate in utility demand response programs and control your electricity consumption during seasonal peak price periods. Using stored energy allows you to manage when and how to use your energy to reduce costs and environmental impact.


Conventionally the surplus electricity generated by home solar system is fed into the grid. However, most homes use a significant amount of electricity in the evening, after their solar panels stop producing. With GMDE energy storage system, excess power is stored in battery and clean energy can be used on-site even when the sun is not shining.


Backup power is a key benefit of GMDE energy storage system. Solar systems won’t work when the grid goes down. With our solution, you can use your solar power when there is an outage with backup power being recharged every day. With sustainable backup power, you rely less on the grid and have an eco-friendly alternative to a fossil fuel burning generator.


Say goodbye to peak energy rates

At daytime:

After supplying power to meet the loads demand, your system is charged by the sun. When your system is fully charged, excess power is fed into the grid.

At night: 

Your system works throughout the night. After your peak demand you can choose to replenish from the grid at off-peak rates for the morning.

When short of sunlight: 

Solar panels alone can’t meet the high evening demand. The system automatically supplies the shortfall by charging from grid.
