48V Hybrid Inverter · Split-Phase · On-Grid or Off-Grid
12,000W of Split-Phase Power From a Single Hybrid Inverter
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.
What the NOVA 12K Handles
High-Power Hybrid Output
- 10,000W continuous output for whole-home backup, cabins, and off-grid systems
- 120/208V and 120/240V split-phase output covers most residential and commercial setups
- Switches between grid-tie, off-grid, and hybrid operating modes
Solar & Battery Management
- 12,000W of PV input capacity for larger solar arrays
- Dual MPPT inputs (2×18A, 30A peak) for flexible panel configurations
- Integrates solar, battery, utility grid, and generator input in one system
Expansion & Smart Control
- Parallels with up to 6 units for larger system capacity
- Built-in WiFi monitoring through the Rich Solar mobile app
- RS485 communication for BMS integration with compatible lithium batteries
Protection & Compliance
- Integrated 300A DC and 60A AC circuit breakers built into the unit
- Arc-fault, rapid shutdown, and ground-fault detection meet NEC 690.11/690.12/690.5
- Certified to UL 1741SA/SB, CSA C22.2 No. 107.1, and IEEE 1547
One Inverter, Four Power Sources
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.

Where It Fits
Common Questions
Is this a grid-tie or off-grid 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.
Can I run this without a battery?
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.
How much solar can I connect?
Up to 12,000W across two MPPT inputs (18A each, 30A peak), with a working DC voltage range of 120–550V.
Can I combine multiple units for more power?
Yes — up to 6 NOVA 12K units can be paralleled together for installations that need more than 10,000W of continuous output.
Does it include circuit protection?
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.
Do I need a licensed electrician to install this?
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.
