Applicable stand-
ards and guide-
lines
CE mark
The devices comply with all the requisite and relevant standards and guidelines that form
part of the relevant EU Directive, and are therefore permitted to display the CE mark.
Grid interface
-
ÖVE/ÖNORM E 8001-4-712
-
VDE 0126-1-1/A1
-
VDE-AR-N 4105
Parallel operation of generators
The inverter conforms to the
-
"Guidelines for connection and parallel operation of generators on the low-voltage
grid" published by the German Electricity Industry Association (VDEW)
-
"Technical guidelines for parallel operation of generators with distribution networks"
published by the Austrian Association of Electricity Companies
Circuit to prevent stand alone operation
The inverter has a circuit, approved by VDE in accordance with VDE-AR-N 4105, to pre-
vent stand alone operation.
Grid failure
The standard measurement and safety procedures integrated into the inverter ensure that
in the event of a grid failure, the feed-in of energy is immediately interrupted (e.g. switch-
off by the energy supplier or damage to lines).
