The Rich Solar NOVA 6500S is a 48V off-grid hybrid solar inverter designed for compatible cabin, recreational vehicle, tiny home, accessory dwelling unit, and off-grid energy systems. It delivers 6,500W / 6,500VA rated inverter output, supports up to 8,000W photovoltaic array input, and uses maximum power point tracking solar charging for properly designed systems. A 5" color liquid crystal display, RGB status lighting, built-in Wi-Fi monitoring, USB functionality, and reserved battery management system communication ports support system visibility and configuration. The inverter is listed with 48VDC battery operation, utility or generator alternating current input compatibility, pure sine wave output, and battery-independent operation where system conditions support it. Photovoltaic array sizing, battery selection, generator integration, breakers, wiring, grounding, parallel setup, and final installation must be completed or confirmed by qualified personnel using current Rich Solar documentation.
The NOVA 6500S combines inverter, solar charger, and battery-charger functions in one unit for compatible off-grid power systems. Rich Solar specifies 6,500W rated output, 13,000VA surge power, and up to 8,000W of photovoltaic array input split across two 4,000W inputs.
This inverter operates with a documented 48VDC battery system and includes configurable charging-source and output-use priorities through the control interface. Supported operating choices include solar-first charging, solar-plus-utility charging, and solar-only charging, allowing a qualified system designer to match charging behavior to the installation plan.
Built-in Wi-Fi supports mobile monitoring through the compatible Rich Solar application, while stored event logs and RGB lighting help users review system status. Reserved RS485, CAN-BUS, and RS232 communication pathways are identified for supported battery management system integration when compatible equipment and correct settings are used.
Rich Solar lists parallel capability for up to six NOVA 6500S units, subject to the manufacturer’s parallel-installation requirements and system design limits. The manual requires qualified personnel for wiring, specifies a solid non-combustible mounting surface, and calls for appropriately sized battery, alternating current, and photovoltaic protection equipment.
The NOVA 6500S provides 6,500W rated output and 8,000W photovoltaic input capacity for compatible professionally planned off-grid solar power systems.
Wi-Fi monitoring, RGB status lighting, a 5" color display, and configurable charging priorities support practical operation and system visibility.
