The inverter is fully automatic. Starting at sunrise, as soon as the solar modules generate
enough power, the automatic control unit starts monitoring grid voltage and frequency. As
soon as there is a sufficient level of irradiance, your solar inverter starts feeding energy into
the grid.
The control system of the inverter ensures that the maximum possible power output is
drawn from the solar modules at all times.
This function is called MPPT (Maximum Power Point Tracking).
As dusk starts and there is no longer sufficient energy available to feed power into the grid,
the inverter shuts down the grid connection completely and stops operating. All settings
and recorded data are saved.
MIX
TM
technology MIX = Master Inverter X-change
Using MIX technology, several smaller power stage sets operate instead of one large pow-
er stage set:
- When irradiance is low, only 3 power stage sets turn on in the inverter.
- In this way, the power stage sets operate in a higher partial-load range than one large
power stage set.
- The energy can then be converted more efficiently, thus significantly increasing the ef-
ficiency.
- The control software alternately assigns the "master power stage set" function to all
the power stage sets.
- When irradiance is high, the other power stage sets switch on in sets of 3.
- A "master power stage set" coordinates and controls the operation of the other power
stage sets.
- Operating hours per power stage set are decreased, and the service life of power
stage sets is increased along with the yield for partial-load operation.
Reliability MIX technology ensures a high degree of reliability due to the number of independent pow-
er stage sets:
if there is a failure in one power stage set, the remaining power stage sets take over for it.
Thus energy losses are limited and only occur when irradiance is high.
