Strengths and limitations
Strengths
- CSA certified to UL 3700 and meets UL 1741 SB (APsystems).
- Two independent inputs for panels from 315 W to 660 W and up (APsystems).
- IP67; Wi-Fi and Bluetooth monitoring in the AP EasyPower app (APsystems).
- 12-year warranty (APsystems).
Limitations
- Bright Saver's circuit math puts the safe plug-and-walk-away limit at 360 W on a shared 15 A circuit. Larger systems need a dedicated circuit or power control, and an electrician.
- The APmeter zero-export control is sold separately and is installed at the electrical panel.
What it does not do
- Keep making power in a blackout: certified plug-in inverters shut down when grid power fails.
- Stop export to the grid on its own: the zero-export meter is a separate purchase installed at the electrical panel.
- Fit in the 360 W of headroom a shared 15 A circuit has: at its full 900 W it needs a dedicated circuit or power control (Bright Saver).

Before you buy
- At full output this is more than a shared 15 A household circuit can safely add. Follow the maker's circuit requirements and your state's wattage cap.
