This video will explain the concept of overpaneling your power station (using more solar panels [total watts] than the max input limit).
Most power stations and solar generators have a solar charge controller (MPPT) that will automatically limit the number of watts or amps going into the battery if you "overpanel" and hook up more solar panel watts than what the power station can input.
As long as the voltage going into the power station is in the correct range (Look at the VOC, open circuit voltage of the solar panels. Do NOT look at the VMP or max power voltage).
The VMP is only useful to calculate how many watts you will get once charging has begun. (VMP is always lower than VOC). If the VOC is too high, charging might not start!
Use VMP X amps to calculate the actual input watts. Some power stations have a low amp limit, and it might not be possible to get the maximum input watts!
If you can overpanel your power station (using the correct voltage by using the solar panels with the appropriate specs, using parallel or series connections where necessary, it is generally a good idea to not exceed the input rating by a large amount (when getting max solar, such as noon on a sunny day).
It's generally advisable to limit overpaneling to slightly above the input rating. Don't go too crazy, unless you have terrible weather and the ability to disconnect excess panels during good weather. (Yes you could leave them attached and rely on the power stations charge controller to limit or 'clip' the power coming in, but as we talk about in the video, that might not be a good idea.)
Lastly, as mentioned in the video, do overpaneling AT YOUR OWN RISK. Every power station, every charge controller is different. Check the input specs (voltage range, max input watts, max input amps), check to make sure it has over-voltage protection & over-current protection and use the appropriate solar panels. DO NOT input a higher voltage.
