aPower 2

AC-coupled battery

Store solar generated power while the sun is shining. Use the

stored energy when needed to lower electric bills. Run heavy

loads such as air conditioners and water heaters as usual even

during grid outages. Provide homeowner peace of mind by fully

charging before severe weather events.

The system is off-grid ready, designed to operate

independently from the main power grid to deliver reliable

energy in any situation.
