HoluPower xP Energy Storage System

HoluPower xP Energy Storage System is the only 3rd Generation Energy Storage System available in Hawaii.


Safer lithium ion battery chemistry – with greater resiliency against overheating and overcharging than other major brands that use less stable, more flammable, and higher toxicity chemistries.

More system power – enough power to enable homes to operate their appliances during an outage, similar to that of utility power.

Greater system modularity – each system can support four strings of PV and up to four 8.2kWh battery modules. Multiple systems can be connected together in a sharing link for even greater capacity.

Higher power for each battery module – a very important attribute for locations where battery subsidies and bonus programs exist.

Energy control – through the Holu Hou Energy Modular Energy Control platform.

Integrated home load control – so both renewable energy supply and load/usage can be scheduled or optimized with one another in real time.

Standard wired internet connection – with optional WiFi or cellular communications.

Better system conversion efficiency – compared to “AC Battery” systems, like those from Tesla.

Making the Smart Home a Reality

HoluPower SmartPanel

The HoluPower SmartPanel is your key to making the Smart Energy Home a reality, with or without solar and energy storage. It allows you to customize your operation of high energy usage appliances in a way that will minimize your utility bill. When integrated with a HoluPower xP solar energy storage system, you can integrate control over both your energy supply and your energy demand. The SmartPanel also allows you to decide which appliances you want to prioritize in the event of a power failure, so your solar and battery can be used for your most vital activities.
