FAQ

How to use a solar power generator?

Set Up the Solar Panels

Positioning: Place the solar panels in an area that receives maximum sunlight, usually facing south in the northern hemisphere and north in the southern hemisphere.
Angle: Adjust the angle of the panels according to your location and season to maximize sunlight capture.
Connect to charge controller: Use the cables provided to connect the solar panels to the charge controller.

Connect the Charge Controller to the Battery

Ensure compatibility: Make sure the charge controller is compatible with the battery type and size.
Wiring: Connect the charge controller to the battery using appropriate cables. Follow the positive-to-positive and negative-to-negative connections.

Connect the Battery to the Inverter

Wiring: Use cables to connect the battery to the inverter, ensuring correct polarity.
Turn on the inverter: The solar inverter will convert the DC power stored in the battery to AC power.

Use the Stored Energy

Plug devices in: Use the power outlets or USB ports on the inverter to connect your devices or appliances.
Monitor power usage: Keep an eye on the battery level through the charge controller or inverter display to avoid depleting the battery completely.

A reliable option for light use.

This 300W solar generator is a handy backup for my small devices and camping trips. The pure sine wave output works well with sensitive electronics, and it handles appliances with a bit of a power surge.
