bigger mppt?

I've got an installation where east side has 6900 peak and it's not possible to add a second cable.

-> any insights if there will be a bigger mppt sometime? e.g. 250/115

regards,
Andy

Hello @N-DEE …..I must confess the question is a little cryptic but have you considered paralleling two or more 250/100 MPPT units? Many can be paralleled to handle more power. They are networked so they share the load.

If he can't run more PV cabling, they can't share the panels, which is what I think he is asking for.

Do you mean divide 1 string over more MPPT's?

Yes. That can’t be done.

You can have multiple mppts each with their own pv array, coordinating charge.

Hi together,

Yes I know that we can't put two Trackers on one Solarcable.
Thats why I was asking if there might be a bigger one than the 250/100 in the future.

br,

Andy

There's already the Smart Solar MPPT RS, 450V, 100 and 200A models.

Yes but they have two or four trackers - but I've got only ONE cable.

Is it possible to bridge the 450/200 from four to one tracker?
