Technical Description
The Automatic Switch Box S then disconnects the loads from the grid, and subsequently connects the
PV system to the consumer grid. Thus, the loads are no longer powered by the public grid, but instead
by your backup system. You can also stop this test with the same function "530.02 BkupTst", and the
system returns to grid-parallel operation.
If you do not manually stop the test, once the battery charge level reaches 50 %, the system
automatically returns to grid-parallel operation, and recharges the battery.
19.5 Battery
19.6 Disposal
Dispose of the devices at the end of their service life in accordance with the disposal regulations for
electronic scrap which apply at the installation site at that time. Alternatively, send the devices back
to SMA Solar Technology AG with shipping paid by sender, and labeled "FOR DISPOSAL" (see
section 24 „Contact“ (169)).
Abnormalities during testing
During the functionality test, fluorescent tubes or bulbs may flicker. This only occurs when
testing.
During real operation, you will hardly notice when the Sunny Backup 2200 switches from
grid operation to stand-alone operation.
No remuneration during the test phase
Note that during the test, your PV system does not feed any power into the grid via the feed-
in counter, and therefore earns no remuneration.
If possible, conduct the test when radiation is low.
NOTICE!
The battery may be damaged if regular inspections and maintenance are not
conducted!
• In this regard, observe the battery manufacturer's specifications.
