3. The interface of this product is DC7909. If you need an adapter cable from MC4 to DC7909, please purchase it yourself.

Car charging

The power station can be charged using a car charging port. It should be charged after the car starts to avoid car battery loss and failure to start. At the same time, ensure a good connection between the car charging port and the cigarette lighter. We take no responsibility for any loss caused by improper operation.

Intelligent inversion

To avoid operation faults arising from charging overload, when the total output power exceeds the rated output power, the constant output power will be automatically enabled, allowing the power station to supply power to high-power devices at the rated output power.

Please take note of the following while using constant power:

1. The constant power output function is not enabled by default and can be turned on or off via the app.

2. The constant power output function is not enabled in the following cases:

3. When AC output is turned on during charging (bypass mode).

4. When constant power output is turned off.

5. The constant power output function is more suitable for heaters and motors instead of all electrical equipment. It is not suitable for some electrical appliances with voltage protection (such as precision instruments). The application of the constant power output function is subject to actual testing.

APP

EPS Function

This product supports the EPS (emergency backup power) function. Connect the power grid to the AC input port of this product using the AC charging cable; it operates in Bypass mode (AC power comes from the grid, not the battery). In the event of a sudden power loss from the grid, the product can automatically switch to battery power supply mode within 14 milliseconds. At this time, it functions in inverter mode. Please note that this function

does not support 0 milliseconds switching. Avoid connecting it to devices that require high uninterrupted power supply, such as data servers and workstations, unless compatibility is confirmed through multiple tests. It is recommended to use only one device at a time to avoid overload protection. If the device does not operate normally or data is lost due to failure to follow instructions, we will not be responsible.
