What a Whole-Home System Can Power
Every system is engineered around your actual electrical loads.
Commonly Supported Loads:
-
Central air conditioning & mini-splits (properly sized)
-
Refrigerators & freezers
-
Lights & outlets
-
Internet, TVs, security systems
-
Well pumps (case-by-case)
-
Garages & EV chargers (case-by-case)
⚠️ Runtime depends on battery capacity, load size, and solar availability.
