Total amateur here so go easy on me. I have a 500WH portable battery (ecoflow river 2 max). I also have a pair of solar panels (specifically these ones). The panels come with a charge controller.
My objective is to use the panels to charge the battery if possible.
The battery solar input spec states a range of [11-50V, 13A, 220W Max]. I understand the ecoflow battery has an integrated MPPT so is able to receive power directly from solar panels without the need for a separate charge controller.
The output spec for the panels is 300W / 18V each which exceeds the specified max input Wattage for the battery, so I am concerned the panels may be overpowered, but also recognise that they would likely operate at a lower output.
I need help firstly to understand if this kit can be used together at all, and if it can, what the appropriate setup configuration is. Example questions i have:
- Given the panels list a (max) 300W output, can they be used to feed the 220W max input of the ecoflow at all? Does this risk frying circuits or are these devices capable of managing excess power?
- If compatible, am I correct to assume the ecoflow's integrated charge controller means a separate charge controller is not needed?
- Could both panels be used or would i be restricted to just one?
- If both, I assume the appropriate config would be to wire in series?
- Anything else i need to consider?
Any advice gratefully received! T
