It combines a solar inverter, MPPT charge controllers, a 48V battery charger\/inverter and an automatic transfer switch in one outdoor-rated enclosure, so you can back up your essential circuits, cut your utility bill with solar and time-of-use control, or run completely off-grid.\u003c\/p\u003e\u003cp\u003eBecause it connects on the load side, the 12K-2P typically avoids a costly main service panel upgrade and needs no external transfer switch.
