Hundreds of show-goers stopped by the Hawaii Energy Con nection booth last weekend for the Building Industry Association of Hawaii (BIA) New Summer Home Building and Remodeling Show at Neal S. Blaisdell Exhibition Hall to check out the company’s innovative and field-proven battery storage system.

It is named “KumuKit Powerblocks™” because of its modular design and how it allows for easy upgrade and incremental expansion to match your needs and solar photovoltaic (PV) production. It is designed to be simple, monitored and controlled by you, with its proprietary Energy Management Controller (EMC) — a device unlike anything on the market today.

Hawaii Energy Connection, the local company known as “KumuKit™,” has surpassed the big mainland companies in battery storage and energy management technology and has been installing many of its KumuKit™ PV systems with battery storage here in the state.


As pioneers of the first utility-approved, A/C-coupled PV battery storage system in Hawaii, KumuKit’s™ PV systems with battery storage are available today; the company has the “fast-pass” to get your system approved and installed quickly.

Under the current utility Customer Self Supply (CSS) program, all solar electricity must be used or stored in batteries for later use, as you will no longer be allowed to export energy back into the utility grid.

The KumuKit Power-blocks™ makes sense for homeowners by providing the capacity to store the less-expensive electricity your PV system generates during the day for use during peak periods, when power demand and cost are the highest — typically in the evening when everyone comes home and begins cooking dinner, taking showers, washing clothes, etc.

Additionally, in the case of a power outage, the battery system can provide critical load emergency backup to the home. Critical loads, such as lighting, medical equipment, refrigerator, television and radio, are important to your family in times of emergency to keep them going without missing a beat, especially during our current hurricane season.


The already-proven KumuKit Powerblocks™ battery storage system is readily available and can start your savings on electricity bills right away. Remember to take advantage of the still available state and federal tax credits (up to 65 percent) and its financing options that make it easy to own.

A great feature of the innovative KumuKit Power-blocks™ is that it connects to new and existing PV systems, and it works together with your solar panels and household electrical devices to create a complete home energy management system.

Take charge of the solar power you generate. In light of all the changes imposed by utilities and regulatory agencies, this transformational storage technology gives consumers more choices and control in their efforts to save money while using renewable energy.

By combining solar and batteries with smart software, KumuKit’s™ energy management system can analyze your home’s energy consumption trends to develop efficiency recommendations that not only limit energy demand, but also define the exact combination of stored and renewable energy required to power the home.
