Any disadvantage from choosing Victron BlueSolar MPPT 75/15 instead of 75/10?

Hello,

from the data sheet it looks as if the Victron BlueSolar MPPT 75/15 is identical to the 75/10 except that it costs approximately 10 EUR more but is capable of charging with 15A rather than 10A.

Is there any reason (except of the 10 EUR) not to choose the 75/15? For my purpose it would be overdimensioned as of now but I may choose to connect larger solar panels sometime in the future.

Best regards,
Daniel

Hi Daniel,

It really depends on the size of your solar panels? What are you planning to connect to the charger? Do you need the ability to monitor the system? In that case it might be relevant for you to look into the SmartSolar version instead of the BlueSolar.

Hi Christoffer,

Thanks for your response. I will probably start with 100W panels to charge a LiFePo4 battery and then expand if I feel that the charging power is too small. For these panels the 10A version should be fine but since they have the same dimensions I thought that I could go straight for the 15A version.

Best regards,
Daniel

Hi Daniel,

Had not seen your reply - sorry for that. So the 75/10 will support up to 750w of panels depending on how well you match the voltage/amps. So unless you plan on adding significantly more panels in the future you might be great off with the 75/10. Look into the smart-version with bluetooth build in.
