The Rich Solar NOVA 12K is a 48V split-phase hybrid inverter designed for compatible residential, agricultural, cabin, accessory dwelling unit, tiny home, and off-grid or grid-connected solar energy systems. This inverter accepts up to 12,000W of photovoltaic input and supplies up to 10,000W rated alternating current output in supported 120/240V or 120/208V split-phase configurations. It integrates photovoltaic power, battery storage, utility power, and supported generator input for professionally designed hybrid power systems. Built-in Wi-Fi monitoring, RS485 battery management system communication, an external current-transformer sensor function, pure sine wave output, and an IP65-rated enclosure support practical system control and installation planning. Because this is high-voltage power conversion equipment, array sizing, battery selection, grid interconnection, generator integration, rapid shutdown, permitting, and final installation must be completed or confirmed by qualified professionals.
The NOVA 12K is built for larger compatible solar and battery systems that require split-phase output. It accepts up to 12,000W of photovoltaic input across dual maximum power point tracking inputs and provides 10,000VA / 10,000W rated output for properly designed 120/240V or 120/208V applications.
This inverter is designed for grid-tie, off-grid, and hybrid operating modes, using compatible solar modules, a 48V-class battery system, utility input, and supported generator input where configured. Alternating current coupling support and external current-transformer sensing help qualified system designers plan self-consumption and energy-flow configurations appropriate to the property.
Wi-Fi and mobile app monitoring support real-time system visibility, while the RS485 interface supports battery management system communication with properly matched battery equipment. Rich Solar lists parallel capability for up to six NOVA 12K units, allowing larger system planning where electrical design, communication settings, protection equipment, and code requirements are confirmed.
The NOVA 12K is listed with an IP65 enclosure, a 300A direct current breaker, a 60A alternating current breaker, arc-fault detection and rapid shutdown functions, ground-fault detection, and photovoltaic input lightning protection. The installation manual identifies the inverter for indoor or outdoor use while requiring a suitable protected mounting location, ventilation clearance, non-combustible mounting surface, and installation by qualified personnel.
The NOVA 12K combines 12,000W photovoltaic input capacity with 10,000W rated split-phase output for compatible professionally designed solar and battery systems.
Hybrid operation, Wi-Fi monitoring, battery communication, generator input and integrated protection functions support flexible energy system planning for demanding properties.
