HECO just announced that Oahu has reached its 25-megawatt capacity limit under the Customer Grid Supply (CGS) program, which means the new program now in place is Customer Self-Supply (CSS). Under this new program, solar customers will not be allowed to expor t energy to the utility grid. Let us introduce you to the Powerblocks™ PV home energy storage system, which the folks at KumuKit™ have been working on for several years.

So much more than just batteries, the Powerblocks™ connects to new and existing PV systems, and works together with your solar panels and household electrical devices that allows you to manage using an Energy Management Controller (EMC), creating a PV energy management system unlike any other in Hawaii or rather on the market today. In fact, all new KumuKit™ PV systems installed now come with this innovative Energy Management Controller.


Power outages from tropical stor ms and electrical grid failure are inevitable. Keep the power flowing and your family going with Power-blocks,™ and you won’t have to suffer through the magain . Power-blocks™ operates silently in the background, providing immediate backup power to lighting, medical equipment, refrigerator, television, radio, phone chargers, fish tank/pond or other critical items that are impor tant to your family in times of emergency.


Save the day and power the night by generating and storing power during the day when sunshine is abundant, and then get it back during the evening and night during high peak hours when electricity is the most expensive. Powerblocks™ maximizes the usage of that energy in your home.

Take charge of the solar power you generate. A Powerblocks™ storage system is right-sized to your family’s needs and, when purchased alongside a PV system, is eligible for the 65 percent tax incentives from the federal and state. KumuKit™ has great financing options available, too.


Every family is unique with their home electricity usage, so knowing the PV system size you will need is a big deal. Under the Customer Self Supply program, it is more important than ever. Purchasing an oversized system can cost you thousands more for extra panels and end up wasting valuable power you generate. Under sized systems aren’t a good deal either. The low cost is appealing, but the low solar production will disappoint you.

How can you find that perfect fit? Allow Hawaii Energy Connection right-size its KumuKit™ PV system for you with its exclusive PV SIZER™ tool to help you visualize the system size you’ll need, and better understand how to maximize its power. It’s an important part of their no-pressure solar analysis.
