Overview
This MPPT 700W waterproof grid tie inverter converts solar PV DC power to AC output with a pure sine wave. It is designed to connect directly to solar panels (no battery required) and supports automatic 50Hz/60Hz operation. Note: this inverter does not have a monitoring function.
Key Features
- MPPT (Maximum Power Point Tracking) with APL (Power Automatically Locked) for stable output at the maximum power point
- Waterproof rating: IP65
- Direct solar panel connection (no battery needed)
- 6-grade power search for low-irradiance conditions
- Pure sine wave output via SPWM (enhancement-mode SPWM); complementary PWM push-pull output waveform
- High-frequency modulation: MOSFET full-bridge; high frequency 50kHz; modulation synthesis 100Hz/120Hz (half wave and full-bridge)
- AC phase-angle auto-detection: AC phase shift < 1%; over-zero protection: 0.2 VAC; AC switching: 50Hz/60Hz
- Constant current / constant power operation
- Automatic islanding protection
- Stacking supported (example provided: 4 units of 260W can reach 1040W); stacking quantity stated as unlimited
