System functions:
◆ 6-level power search - the solar cell's output current is extremely small on a cloudy day, and the inverter automatically turns on the 6-level power search function to achieve stable and efficient power output at low power.
Greatly increase the power generation of the power generation system throughout the day.
◆ Wide voltage input (22-50VDC) - achieves wide voltage input. 1. DC voltage input: 22-50VDC; 2. Secondary power transformer conversion;
◆ High-frequency two-way grid connection, one-way grid-connected function——1. High-frequency direct modulation, AC half-wave synthesis 2. Two-way grid-connected mode: direct load consumption, reverse transmission of AC current;
◆ Multi-frequency output function - can be applied to AC AC at 50Hz/60Hz frequency, frequency range: 45 50 54/55 60 64 Hz.
◆ Direct connection to solar panels (no need to connect batteries) - Accurate dynamic differential pressure MPPT function, APL function, automatically adjust the solar panel power to the maximum
Output, just connect the solar panel directly to the grid-connected inverter, no need to connect the battery.
◆ AC high-angle phase high-precision automatic detection——High-precision detection and analysis of the angular phase of AC, phase shift rate is only <1%, thus achieving high-precision in-phase modulation AC power combined output function.
1. AC phase shift: <1%; 2. Zero-crossing protection: 0.2VAC; 3. AC switching: 50Hz/60Hz;
◆ Synchronous high-frequency modulation - This product first rectifies AC power to 100Hz half-cycle AC, and then combines high-frequency current with 100Hz half-cycle AC 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 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 mode: enhanced high-speed SPWM;
◆ Automatic power lock (APL) - MPPT function is used under different current intensity fluctuations. When the MPPT function is adjusted to the maximum power point, the product automatically performs work.
The rate is locked at the maximum power point to make the output power more stable, and the power is locked: the maximum point value of the 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 there will be no overload or overcurrent phenomenon.
◆ The output is automatically turned off when the grid is faulty. When the mains grid is out of power and the grid is faulty, the inverter will automatically turn off the output.
◆ Current Limit Protection - This product is constant current, constant output power without overload and overcurrent.
◆ High frequency and high conversion rate - high frequency conversion makes the output more efficient.
◆ Maximum Power Point Tracking (MPPT) – This product uses high-precision MPPT (Maximum Power Point Tracking) computing power to automatically and in real time adjust the output power of the solar panel.
At the largest output point, a stable output is achieved, allowing the system to discharge the grid-tied inverter to the grid with maximum efficiency.
◆ Stacking - In order to achieve higher power usage requirements, this product can be stacked. For example, four 260W grid-connected inverters are equal to 1040W, and the number of stacks is not limited.
◆ DC input limit - input voltage range: 22V to 50V, solar panel: recommended power is greater than 30W; standard voltage 36V photovoltaic panel. Parallel solar cells are recommended
Board, series connection will cause the input voltage to 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, 50/60Hz, the grid voltage that can be used by the inverter that outputs 120V AC
Range: 80V ~ 160V, 60 / 50 Hertz.
