Solar Battery Systems

Big Island Backup or Off Grid Power

Now that NEM and CGS programs have been closed across the Hawaiian Electric service territories, the Customer Grid Supply Plus (CGS+) design is the most practical and cost-effective option for Big Island homeowners like you who want to go solar electric.

Solar battery systems plus battery storage allows CGS+ customers to store and use solar-generated power at night, automatically pulling power from the utility only when you need it. These systems merge seamlessly into your home’s electrical system to maximize the power of your PV system while giving you all the convenience of grid-supplied power. Plus, these battery systems can offer back-up power during utility outages. Imagine that worry-free feeling when the grid goes down.
