Sol-Max's flagship hybrid inverter, formerly the MidNite MN15-12KW-AIO "The One", handles off-grid, backup and advanced grid-tie systems. It's a true 5-in-1 unit: inverter, charger, 3-MPPT solar controller, smart panel and sub panel in one outdoor-rated enclosure. It delivers 11.4kW continuous with PV and 10kW on battery alone, with a 20kW one-second surge and full 100% imbalanced-load support, so 120V motor loads start without drama.
Highlights
- High surge: 20kW (84A) for 1 s at 240V; 13kW (108A) on a 120V leg
- 5-in-1 design: inverter, charger, MPPT, Smart Panel and Sub Panel
- 3 MPPT trackers: 15kW PV, 600VDC max, integrated PV disconnect
- Three SmartLoad outputs (60A, 50A, 30A) for load shedding and opportunity loads
- CBI hydraulic-magnetic breakers on every input and output for easier code compliance
- Off-grid ready: built-in auto generator start (two-wire)
- Stackable: up to 9 units at 240V (90kW), or 3 units for 208V three-phase (30kW)
- Plug-and-play with Sol-Max PowerFlo batteries: no DIP switches or firmware fiddling
- Arc fault, ground fault and rapid shutdown built in, plus surge suppression
