Solar Battery Systems

Big Island Backup or Off Grid Power

Now that NEM and CGS programs have been closed or limited across the Hawaiian Electric service territories, the Customer Self Supply (CSS) design is the most practical and cost-effective option for Big Island homeowners wishing to go solar electric. New solar battery systems are now available that allow CSS customers to store and use solar-generated power at night and automatically pull power from the utility when needed. These systems integrate 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.
