The Rich Solar NOVA MAX 3K is a 24V off-grid hybrid solar inverter designed for compatible recreational vehicle, trailer, camper, van, overland, boat, and compact off-grid power systems. Identified by SKU RS-H3024 and technical model NOVA 3K24, it provides 3,000W / 3,000VA rated pure sine wave output for properly sized electrical loads. Its built-in maximum power point tracking solar charge controller supports a photovoltaic operating range of 90–230VDC, with a 250VDC maximum photovoltaic array open-circuit voltage. The inverter also supports a 24VDC battery system, compatible utility or generator input, configurable charging priorities, liquid crystal display controls, cold-start capability, and overload, over-temperature, and short-circuit protection. Photovoltaic array sizing, battery-bank selection, generator or utility input, circuit protection, grounding, and final wiring must be completed or confirmed by qualified personnel using current Rich Solar instructions.
The NOVA MAX 3K combines inverter, solar charger, and battery-charger functions in one unit for supported off-grid electrical systems. Rich Solar specifies 3,000W rated output, 120VAC ± 5% output regulation, pure sine wave output, and surge capability of twice rated power for five seconds.
The built-in solar charger is specified with one maximum power point tracker, an operating voltage range of 90–230VDC, 18A maximum photovoltaic input current, and 250VDC maximum photovoltaic array open-circuit voltage. These ratings provide the critical upper limits qualified designers need when planning compatible solar strings.
The inverter allows charging-current adjustment, alternating current or solar charging priority selection, and input-voltage configuration through its liquid crystal display controls. Rich Solar identifies sinusoidal utility or generator power as supported alternating current input sources for correctly configured systems.
The NOVA MAX 3K includes manufacturer-listed overload, over-temperature, and short-circuit protection along with automatic restart during alternating current recovery and cold-start functionality. The manual requires qualified-personnel wiring, a solid non-combustible mounting surface, direct current battery over-current protection, an alternating current breaker, and photovoltaic circuit protection and surge protection as appropriate to the installation.
The NOVA MAX 3K supplies 3,000W rated pure sine wave output for compatible 24V off-grid solar and battery systems.
Integrated MPPT solar charging, configurable LCD settings, and utility or generator input support practical system design for mobile and remote-power applications.
