7.3.6.5 Reactive Power Control for Slovenia (SONDO) for 15 / 20 / 30 TL Models
When selecting Slovenia from the Country setting list on initial start up, it is possible to adjust
reactive power parameters for Q(V) according to two curves, class B and class C. The Slovenian
requirements are known as SONDO or SOIEDN (System operation instructions for electricity
distribution network). Q(V) is the reactive power ratio Q/S
n
in dependency of the voltage V.
CAUTION
Machine and equipment damage may occur.
► Please only adjust these reactive power settings if you are a qualied
electrical technician with the knowledge to do so
► Adjustments may affect energy production
► Some values entered in the Reactive Power settings must come from
the local grid operator. Please check with them before making any
adjustments
NOTE
The inverter is only able to feed-in reactive power in Class B or Class C set-
tings when the Power output is greater than 5% of Pn.
