Solbian SP-52L / MPPT 75/15

Hi All,

Apologies for the newbie question: I'm thinking of mounting one or two Solbian SP-52L panels on my sailboat. The specs for these panels are:

52W

Voc: 10.9V

Vmp: 9.1V

Isc: 6A

Ipm: 5.7A

If I've understood correctly, I would indeed need to wire at least two of these panels in series in order to use my MPPT 75/15 (i.e. to achieve the required minimum voltage). One panel alone would not work in this configuration. Is this correct?

Thanks!

@metamark

presuming you have a 12 volt battery.

Yes that is correct, as the required minimum voltage to start the mppt 75/15 is battery voltage + 5 volt.

As you are still “thinking“ about these panels, I suggest to look for other panel(s) with a higher Vmp.

so that you use the 75/15 to it’s max
