What size SmartSolar MPPT?

Good day guys,

I am about to install the following system at home:

2 x Victron Multiplus II 48 /5000

1 x Victron SmartSolar MPPT RS 450 /100

1 x 14.3kwh Solar MD battery (Maybe 2)

22 x 545W Solar panels

I somehow think the SmartSolar MPPT RS 450/100 might not be sufficient.....

Any advice will be most appreciated.


Regards,

JHP

Hopelessly too small.

Please have a professional assist you.

That is a lot of panel for those inverters and battery, no amount of over-subscription will compensate for the Cape's winter weather.

Thanks nickdb, how would you suggest I configure my system around 2 x 5kva MP II?
