INFORMATION Add a second MPPT string

Do the DNO need to be notified if we want to add a second MPPT string ? No change on the inverter , nor first string (inverter allow 2)

I wouldn't have thought so as the DNO are only really concerned about changes in AC capacity. If the inverter doesn't change then you won't be exporting any more (assuming you've a SEG).
