Overview
This Grid Tie Inverter is a SolarEpic waterproof MPPT unit rated at 300W (RMS 300W), designed to connect directly to 24V/36V solar panels (battery connection not required). It accepts 22–50VDC PV input and outputs AC 110V or 220V with automatic 50Hz/60Hz operation. The enclosure is rated IP65 and the inverter is CE certified. Note: this inverter does not have a monitoring function.
Key Features
- MPPT (Maximum Power Point Tracking) with Power Automatically Locked (APL) at the maximum power point
- Pure sine wave output (SPWM)
- Wide DC input range: 22–50VDC
- IP65 waterproof design for outdoor-capable installation
- 50Hz/60Hz compatible: frequency range 45Hz–64Hz
- 6-grade power search for low-power conditions (e.g., overcast weather)
- Stacking supported (example provided: 4 × 260W = 1040W; stacking quantity stated as unlimited)
- Protection functions indicated by LED status: islanding protection, over-temperature, over/low AC voltage, over/low DC voltage, fault
