Dealer/Installer from New Zealand.
We install a lot of systems with two MPPT's 100/30's and 100/50 SmartSolar are most common.
We have had 2 instalations in recent times where the MPPT's have stopped generating and stayed off until the customer became aware, in both cases as soon as the Virtual Network was disabled, the MPPT's fired up.
Both systems had been running faultlessly for weeks in one case months in the other.
Both were with Smart Shunt.
Interested to hear if others have had this issue?
