Derating
A controlled reduction in performance, usually dependent on component temperatures
SMA Power Balancer
The SMA Power Balancer is a serial feature of the Sunny Mini Central. The SMA Power Balancer
prevents the formation of an excessive unbalanced load during three-phase feed-in. This is enabled
by connecting three Sunny Mini Centrals to a three-phase feed-in unit via a control cable.
Unbalanced Load
The unbalanced load is the difference between the power being fed into the grid by the individual
line conductors. This depends on the configured country data set and may be between
4.6 kVA and 6 kVA.
Varistor
The varistors protect the electronics in the inverter from atmospherically coupled energy peaks, such
as those which can occur e.g. when lightning strikes nearby.
