Commissioning
Parallel in Single Phase
CAUTION: Before continuing, ensure the wiring is correct according to the previous chapter, particularly that
all units are connected to the same neutral wire. Ensure that all AC input breakers and AC output breakers are
open on each individual Any-Grid unit and that each unit is turned off with its AC output on/off switch. Ensure
each unit is disconnected from PV, but connected to the battery via its battery breaker / fuse. The battery
breaker must be closed / inserted to ensure each unit can function for commissioning.
Follow the following steps once the wiring is completed.
1. Turn on one unit with its AC output on/off switch
2. In the Settings Menu (see chapter "Device Operation Settings") navigate to settings menu 28.
3. Turn the AC output on/off switch off to deactivate the AC output. The unit will remain in Stand-By mode for
under a minute and the display will stay on for this time.
4. Set the menu number 28 setting from the default value "Single" (SIG) to "Parallel" (PAL). This will not be
possible if the unit is not turned off as described in the previous step.
5. Once the setting is confirmed, wait for the unit to shut down automatically, the display will then turn off
completely.
6. Repeat steps 1 to 5 with each further unit connected in parallel.
7. Now turn on each unit. One unit will automatically and randomly be defined as the master unit and will
show the master screen, all other units will show the slave screen on their display:

8. Switch on the AC input breaker of each unit in quick succession, if an AC source is installed. If this takes too
long, then some units may show fault 82 on their screen, but they will restart automatically and upon
detecting a valid AC input, will function normally.
9. It's better to have all inverters connect to utility at the same time. If not, it will display fault 82 in following-
order inverters. However, these inverters will automatically restart. If detecting AC connection, they will work
normally.

10. If there are no further faults displayed, the parallel system installation is complete. The breakers on the AC
output of each unit can be switched on and then loads may be connected.
3-Phase, One or more Units per Phase
CAUTION: Before continuing, ensure the wiring is correct according to the previous chapter, particularly that
all units are connected to the same neutral wire. Ensure that all AC input breakers and AC output breakers are
open on each individual Any-Grid unit and that each unit is turned off with its AC output on/off switch. Ensure
each unit is disconnected from PV, but connected to the battery via its battery breaker / fuse. The battery
breaker must be closed / inserted to ensure each unit can function for commissioning.
