A grid-tied solar kit built to cut your electric bill. The FlexBOSS21 and GridBOSS MID run household loads such as AC, water heaters, well pumps and refrigerators directly from twelve 450W panels during the day. Any surplus can be exported for net metering or sell-back where your utility offers it. Add batteries later to turn it into a full backup system.
Highlights
- Turn excess solar into savings through net metering or sell-back programs
- Power more of your home, including HVAC, pool equipment and EV chargers
- Expandable: add more solar or storage as needs or rates change
- Monitor savings in real time from anywhere
- Solar first: intelligent energy management reduces purchased power
