3.5KVA/3.5kW Off-Grid Hybrid Inverter

The Off-Grid Hybrid Inverter with a rated power of 3.5KVA/3.5kW and a system voltage of 24VDC, it efficiently manages solar, battery, and AC grid inputs.
Off-Grid Hybrid Inverter equipped with pure sine wave output, it delivers stable 220/230/240VAC power with a conversion efficiency of 93%. The switchover time is optimized at 10ms for PCs and 20ms for home appliances, ensuring seamless transitions.
The battery system operates at 24VDC, with a float voltage of 27VDC and overvoltage protection at 33VDC. The solar charger supports up to 4kW input power, with an MPPT voltage range of 12–450VDC and a maximum input voltage of 320VDC/500VDC. It efficiently handles 18A input current and 80A charging current.
For AC charging, the Off-Grid Hybrid Inverter accepts a 230VAC input, with a voltage range of 90–280VAC for home appliances and 170–280VAC for PCs. The adaptive frequency range of 50Hz/60Hz ensures compatibility with various grid conditions, while the maximum charge current of 40A/60A enhances battery performance.
With a compact 9kg design, an LCD display, and RS485 communication interface, this Off-Grid Hybrid Inverter offers user-friendly monitoring and control. Designed for harsh environments, it operates reliably between -25°C to +55°C, with IP20 protection and 5%–95% non-condensing humidity tolerance.
