MPPT (Maximum Power Point Tracking) is the method of tracking the maximum power point. The output power of a photovoltaic module is related to the amount of sunlight that hits the solar panel and the electronic characteristics of the load. When the sunlight conditions change, the maximum power that can be provided also changes. By adjusting the load to operate at the highest power point, the system will achieve optimal efficiency.

The maximum power tracking voltage range for a micro-inverter with photovoltaic modules is 22-55V. Within this range, the micro-inverter can achieve the maximum power conversion from the DC voltage of the photovoltaic module. Below 22V, the micro-inverter will not work. If the voltage exceeds 55V but is below 60V, the micro-inverter will still operate. However, exceeding 60V may damage the micro-inverter.

Multiple micro inverters are connected in parallel, and the maximum current of the AC bus 12AWG (3X2.5mm²) is 20A, which determines the maximum number of micro inverters connected to each AC branch. The specific quantity can be found in the specifications of each model.
If the AC bus has different specifications, the maximum number of micro-inverters that can be connected to each AC branch will vary.

The rated output voltage of the micro inverter is 220V, 230V, 203V, 240V, and the frequency is 50Hz, 60Hz. Depending on the grid requirements of different countries or regions, the upper and lower limits will be set before leaving the factory. If the limits are exceeded, the microinverter will protect itself. Please contact us for modification.

 

The microinverter is a grid-tied inverter, and it will not work when there is no power in the grid or if the grid is not available. Therefore, it cannot be used off-grid.

Yes, it has UPS functionality. By connecting to the power grid via the AC power cable, devices can use the product’s AC output port for power (at this point, the AC power comes from the grid, not the battery). If the grid power suddenly goes out, the product will automatically switch to battery power within 20ms. Since this product does not support 0ms switching, do not connect it to devices that require continuous power, such as data servers and workstations, or please confirm compatibility through multiple tests before use.

Sure, the power supply supports simultaneous charging and discharging. During charging, AC power is prioritized to directly supply the load, and any excess power will be used to charge the battery.
 

No, because this product uses a lithium-ion battery. Acording to airline transportation standards, carrying lithium battery products cannot exceed 100Wh.
