Product Information
The Micro Inverter is a smart inverter designed by Expert Green Energy, which comes with an IoT monitoring platform. It offers features like CO-2 induced environmental analysis, daily and total energy generation in kWh, actual DC input voltage, current and power, actual AC output voltage, current and power, inverter temperature, historical (daily, weekly, monthly) power curve, power losses due to weather-induced effects, optional limitation of power output, and online switch for the inverter start-stop. The model number of the Micro Inverter is WVC-700, and it is recommended to use panels of 2430Watt. The Micro Inverter has an output voltage mode of 120/230V Auto switch. It supports a PV open circuit voltage of 30-60VDC and has an operating voltage range of 22-60V with a starting voltage range of 22-60V. The Micro Inverter has a short-circuit current of 216A and a maximum working current of 2*14A. It offers output parameters @120V and @230V, with an output peak power of 700Watt at both voltages. The rated output power is 680Watt at both voltages, and the output current is 5.9A @120V and 3.05A @230V. The AC voltage range supported by the Micro Inverter is 80-160VAC @120V and 180-280VAC @230V. It supports AC frequency range of 48-51Hz/58-61Hz at both voltages, with a power factor greater than 95%. The Micro Inverter supports six or twelve branch connections depending on the model and has an output efficiency of 95% @120V and @230V. The static MPPT efficiency is 99.5% at both voltages.

System diagram
Note: You can purchase a professionally customized AC bus with a T-type connector. Use this AC bus as the AC bus for each branch. Connect it hand in hand to form a modular micro-inverter branch wiring system.
LED indicator function of micro-inverter
- Red light keeps on ——————————–The equipment enters the preparatory working state;
- Red light flashes ———————————- The device enters the delayed start-up state;
- Blue light flashes quickly ————————MPPT maximum power point search status;
- Blue light keeps on ——————————–MPPT maximum power point locked state;
- Blue light turns to red light for a long time
- a) Island protection;
- b) Frequency protection;
- c) Fault;
- d) Software shutdown;
- e) AC voltage over-voltage protection;
- f) DC voltage over-voltage protection;
Normal working indicator flashing process
Connect the micro-inverter correctly to the AC and DC terminals and then power
on: The red light keeps on for 3 seconds → the red light flashes for 30
seconds → the blue light flashes quickly (MPPT maximum power point search) →
the blue light keeps on, (MPPT lock).
