500w Micro Grid Tie Inverter For Solar Wind Home System MPPT DC 22-60V AC 220V. Input DC10.5V28V Output AC180V260V. When the 125VAC LED lit up, it means the AC output is 125V. When the 230VAC LED lit up, it means the AC output is 230V. When the Fault LED lit up, is means there is no electricity or the output is fail, and the inverter restart. Power output LED: The 5 red LEDS take turns lighting, the quicker the lights move, the more power output. When the 50Hz LED lit up, it means the input frequency is 50Hz. When the 60Hz LED lit up, it means the input frequency is 60Hz. HIGH LED lit up, it means the DC input is over 62VDC. DC under- voltage display. When LOW LED lit up, it means the DC input is low 14VDC. When ST LED flashing, it means power is in adjusting condition. When ST LED long on time, is means the power is locked, and the inverter works. In overcast weather, the solar batterys output current is extremely tiny, then inverter will automatic open 6-grade power search function. The program can automatically open power adjustment for 6 times. The current direction can adjust from the maximum to the minimum. In automatic adjustment process, we will see the LOW light flashing. And the power will keep as a starting point, from 0 to the maximum output power, and it will restart at most for 6 times, then locked in the maximum power, the ST lamp long bright. It need 10 minutes for 6-grade power search. Wide voltage input(22-60VDC). Achieve wide voltage input. DC voltage input: 22-60VDC. Second level power variable voltage conversion. High-frequency two-way and one-way grid function. High frequency direct modulation, AC half wave synthesis. Two-way grid means: Load consume directly. And can reverse AC current transmission. One-way grid means: Load consume directly. And banned reverse AC current transmission. Kinds of frequency output function. It can apply to 50Hz and 60Hz frequency of AC. Frequency range: 45Hz 63Hz. Directly connected to the solar panels (do not need to connect the battery). Using precise Dynamic differential pressure type MPPT function, APL functions, the inverter automatically adjust the solar panels of maximum output power, simply connect the solar panel to the grid inverters. Do not need to connect the battery. Differential pressure type MPPT: 0.1 V accuracy. Power lock: 10W (AC output). AC 0 angle with high precision auto-detection. AC phase angle of 0 through isolation amplifier then input to the MCU for high-precision detection and analysis. The phase shift rate is less than 1%, thus achieve high-precision with phase modulation AC output together. AC phase shift: < 1%. Over-zero protection: 0.2 VAC. AC switching: 50Hz / 60Hz. In the process of the grid, usually adapt the same phase angle in parallel. Ie, When the two-phase alternating current total is equal to 0. Use switch to combination the two AC fusion and the product is rectified AC half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation. Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz). Synthetic way: MOSFET full-bridge. Pure Sine Wave Output. Use SPWM directly to make pure sine wave output. Output waveform: Adopt complementary PWM to push-pull pure sine wave. Generate means: enhancement-mode SPWM. Maximum Power Point Tracking (MPPT). 500w 22-60v DC 220v AC Grid Inverter. 1.8M AC power.
