Hi there i now have 6x 220w ( 1320w)  connected to a MS MPPT60 running at 24v so the limit announced is 1600W.
I want to add another 2 panels so i will have a total of 1760W, even if this is a bit upper than the max allowed what will be the behavior will it blow up or not ?
i expect that in peak will not use more than the 1600w but that additional 160w will not damage the controller ?

in morningstar grid calculator this setup appear as valid, any one using a mppt60 with more pv watts than the max capacity ?

Hi there, Just to let you know the morningstar support answer :

" Hi Francisco,

Yes, you can use all 8 panels in this configuration for 1760W with the TSMPPT 60 controller.

The 1600W maximum you may have noticed in the controller datasheet (in a 24V system) is the effective limit to how much power the TSMPPT 60 will deliver to the batteries. Oversizing the array slightly (like you are doing) is not harmful to the TSMPPT and in practice will help you get more out of your system during non-peak sunlight conditions.

Regards"


thanks
