NOVA 6500S 6500W 48V Off-Grid Hybrid Solar Inverter

The NOVA 6500S is a 6500 Watt (6.5 kW) 48 Volt off-grid hybrid solar inverter engineered to deliver reliable, scalable power for remote dwellings, off-grid workshops, and backup systems. Its battery-independent design enables operation without a battery for lighter loads, while full compatibility with AGM, Pylontech, WECO, Soltaro, LIB-Protocol, and third-party lithium chemistries supports a wide range of energy storage configurations.

Continuous power 6500W with a peak of 13 kW. In parallel, up to six units can operate in single-phase, split-phase, or 3-phase configurations, delivering up to 39 kW total for demanding applications. MPPT control spans 90-230 VDC with a max efficiency of 91%, preserving battery life and maximizing solar harvest. The unit provides a wide AC input/output range (80-140 VAC) and high-power charging (10-120 A). The pure sine wave output ensures compatibility with sensitive electronics and quiet operation.

Smart features include built-in Wi‑Fi for real-time monitoring via Android/iOS apps, RGB status indicators, USB On-the-Go data transfer, internal event logging, and a reserved BMS communications port (RS485, CAN‑BUS, RS232). Optional DC output supports fans, LED bulbs, or routers. Three load-output modes and three charging modes enable flexible power prioritization and energy management aligned to solar generation and grid or generator inputs.

Safety and durability are addressed with UL certification, overload and short-circuit protection, over-temperature protection, and anti-dust kit integration. The replaceable fan design simplifies routine maintenance, while straightforward installation and smart control streamline commissioning and operation.
