48V Hybrid Inverter · Split-Phase · On-Grid or Off-Grid
The NOVA 12K handles solar, battery, utility, and generator input in one UL 1741-certified unit — 10,000W of continuous 120/240V split-phase output with 12,000W of PV input capacity, built for whole-home backup, cabins, and off-grid living.
Most off-grid setups end up juggling separate hardware for solar charging, battery management, and grid or generator backup. The NOVA 12K folds all of that into a single hybrid inverter — solar, battery, utility, and generator all route through the same unit, coordinated automatically rather than requiring a rack of separate boxes.
At 10,000W continuous with 12,000W of PV input headroom, it's sized for more than a backup role: whole-home systems, ADUs, and off-grid cabins with real daily loads. Split-phase 120/208V and 120/240V output covers standard residential wiring, and up to six units can be paralleled together for installations that outgrow a single inverter.

Both — the NOVA 12K supports grid-tie, off-grid, and hybrid operating modes, so it can run connected to utility power, fully off-grid, or switch between the two depending on how it's configured.
It's built as a hybrid inverter designed to work with a 48V battery bank alongside solar, grid, and generator input. Check with Rich Solar on specific battery-free operation if that's part of your setup.
Up to 12,000W across two MPPT inputs (18A each, 30A peak), with a working DC voltage range of 120–550V.
Yes — up to 6 NOVA 12K units can be paralleled together for installations that need more than 10,000W of continuous output.
Yes — a 300A DC breaker and 60A AC breaker are built into the unit, along with arc-fault, rapid-shutdown, and ground-fault detection meeting NEC 690.11, 690.12, and 690.5.
Given the voltages, currents, and grid-interconnection requirements involved, installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
