General

Explanation of
safety notices
Indicates a potentially hazardous situation.
► If not avoided, death or serious injury may result.
Indicates a situation where damage or injury could occur.
► If not avoided, minor injury and/or damage to property may result.
NOTE!
Indicates a risk of flawed results and possible damage to the equipment.
IMPORTANT!
Indicates tips for correct operation and other particularly useful information.
This does not indicate a potentially hazardous situation.
If you see any of the symbols depicted in the "Safety rules" chapter, special care is re-
quired.

Device concept

The inverter has been developed exclusively for use in grid-connected photovoltaic sys-
tems; it is impossible to generate energy independently of the public grid.
The inverter automatically monitors the public grid. In the event of abnormal grid condi-
tions, the inverter ceases operating immediately and stops feeding power into the grid (e.g.
if the grid is switched off, if there is an interruption, etc.).
The grid is monitored by monitoring the voltage, monitoring the frequency and monitoring
islanding conditions.

The inverter converts the direct current cre-
ated in the solar modules into alternating
current. This alternating current is fed into
the public grid synchronously with the grid
voltage.
