 ◆ 6-level power search - the output current of the solar cell is extremely small when it is cloudy, and the inverter automatically turns on the 6-level power search function to achieve continuous, stable and efficient power output at low power, and greatly improve the whole day power generation of the power generation system .

 ◆ Wide voltage input (22-50VDC) - realize wide voltage input. 1. DC voltage input: 22-50VDC; 2. Secondary power transformer conversion;

 ◆ High-frequency two-way grid connection, one-way grid connection function - 1. High frequency direct modulation, AC half-wave synthesis 2. Two-way grid connection method: direct load consumption, reverse AC current transmission;

 ◆ Multi-frequency output function - can be applied to AC alternating current of 50Hz/60Hz frequency, frequency range: 45 50 54/55 60 64 Hz.

 ◆ Directly connected to the solar panel (no need to connect the battery) - using the precise dynamic differential pressure MPPT function, APL function, automatically adjust the power of the solar panel to the maximum

 output, just connect the solar panel directly to the grid-tied inverter, no need to connect the battery.

 ◆ High-precision automatic detection of AC 0 angular phase - high-precision detection and analysis of the angular phase of AC, the phase shift rate is only <1%, thus realizing the high-precision in-phase modulation AC combined output function.

 1. AC phase shift: <1%; 2. Zero-cross protection: 0.2VAC; 3. AC switching: 50Hz/60Hz;

 ◆ Synchronous high-frequency modulation - This product first rectifies the alternating current into 100Hz half-cycle alternating current, and then combines the high-frequency current with the 100Hz half-cycle alternating current in the circuit to achieve high

 frequency modulation. 1. Modulation synthesis: half-wave full bridge modulation synthesis; 2. Synthesis method: MOSFET full bridge; 3. High frequency: 50KHz;

 ◆ Output pure sine wave - use SPWM to directly generate pure sine wave output.

 1. Output waveform: using complementary PWM push-pull, pure sine wave; 2. Generation method: enhanced high-speed SPWM;

 ◆ Automatic Power Lock (APL) - Under the fluctuation of different current intensity, the MPPT function will be used. When the MPPT function is adjusted to the maximum power point, the product will automatically adjust the power

 The rate is locked at the maximum power point to make the output power more stable. Power lock: the maximum value of MPPT.

 ◆ Automatically adapt to different load power factors - adapt to any power load.

 ◆ Constant current, constant power - This product is constant current, constant output power, and will not appear overload, overcurrent phenomenon.

 ◆ Automatically turn off the output when the power grid is faulty - when the mains power grid fails and the power grid fails, the inverter will automatically turn off the output.

 ◆ Current limit protection - This product is a constant current, constant output power, and will not appear overload, overcurrent phenomenon.

 ◆ High frequency and high conversion rate - high frequency conversion is adopted to make the output more efficient.

 ◆ Maximum Power Point Tracking (MPPT) - This product uses high-precision MPPT (Maximum Power Point Tracking) computing power to automatically and real-time adjust the output power of the solar panel within the

 At the maximum output point, the purpose of stable output is achieved, so that the system discharges the grid-connected inverter to the grid with the highest efficiency.

 ◆ Stacking use - In order to meet the requirements of higher power use, this product can be used in stacking, such as: 4 260W grid-connected inverters are used in stacking equal to 1040W, and the number of stacks is not limited.

 ◆ DC input limit - input voltage range: 22V to 50V, solar panel: recommended power greater than 30W; standard voltage 36V photovoltaic panel. Parallel solar cells are recommended

 If the board is connected in series, the input voltage will be too high and exceed the operating voltage range of the inverter.

 ◆ AC output - the grid voltage range that can be used by the inverter that outputs 220V AC: 180V～262V, 50/60 Hz, the grid voltage that can be used by the inverter that outputs 120V AC

 Range: 80V ~ 160V, 60/50 Hz.
