Rich Solar RS-H6548S NOVA 6500S 48V 6.5kW Off-Grid Hybrid Solar Inverter
The Rich Solar RS-H6548S NOVA 6500S is a 48V off-grid hybrid solar inverter built for serious solar, battery backup, and off-grid power systems. With pure sine wave output, built-in MPPT charging, Wi-Fi monitoring, flexible battery support, optional battery-free operation, and parallel expansion up to 6 units, it gives larger systems the power control and scalability needed for demanding applications.
Heavy Load Power
Delivers 6500W of continuous output with up to 13kW peak power for compatible high-demand appliances, tools, and off-grid loads.
MPPT Solar Charging
Built-in MPPT control helps maximize solar charging efficiency while supporting flexible solar and battery system design.
Smart Monitoring
Built-in Wi-Fi works with Android and iOS mobile monitoring through the Rich Solar app for real-time status, usage tracking, and data logging.
Battery Flexible Design
Supports battery-based systems and battery-independent operation for lighter loads when solar panel output is stable.
Product Overview
The Rich Solar RS-H6548S NOVA 6500S Hybrid Solar Inverter is designed for larger 48V off-grid solar systems, backup power installations, cabins, workshops, farms, remote buildings, and energy storage projects. It combines inverter output, MPPT solar charging, AC charging, generator or utility input, smart monitoring, and configurable power priorities in one advanced power platform.
With 6500W of continuous power and up to 13kW peak output, the NOVA 6500S is built for demanding loads while maintaining clean pure sine wave power for compatible appliances and electronics. For larger projects, up to 6 units can be operated in parallel for expanded output capacity in single-phase, split-phase, or 3-phase configurations.
The RS-H6548S also supports battery-independent operation for lighter loads when solar production is stable. When batteries are used, the inverter is compatible with multiple battery types and communication options, including AGM, Pylontech, WECO, Soltaro, LIB-Protocol, and third-party lithium batteries when properly configured.
