6.4.1 Connecting to load circuits via backup sub-board
The backup load circuits can be either wired directly from a dedicated backup sub-board supplied via the
sonnenProtect accessory. Alternatively, the circuits can be fed from the existing switch panel which in turn is
fed from the sonnenProtect accessory output cable in addition to the normal grid supply.
The supply to the circuits powered from the sonnenProtect need to be protected by the 30mA RCBO which
has been supplied with the sonnenProtect 1300-AU-IN-ATS kit set.
If the loads are to be fed directly from the existing switch panel, then it is important to clearly label and identify
those circuits being supplied as they will automatically be powered even when the grid has failed (when there is
sufficient battery supply to enable the sonnenProtect).
It is essential that under normal load condition the appliances and/or load circuits being supplied by the
sonnenProtect do not exceed 6A (1300W). All loads after the RCBO will need to be protected by the 6A MCB
supplied with the sonnenProtect accessory set.
In some circumstances the combined power draw of both full charge rate of the sonnenBatterie (3300W) as
well as the full power supply of the sonnenProtect (1300W) need to be considered. To enable this situation,
included within the sonnenProtect 1300-AU-IN-ATS kit set is a 25A main MCB which should be used as the
sonnenBatterie MCB (Main AC isolator). In addition to the higher rating of the protective device the supply
cable itself depending upon route length and location may also need to be replaced with a larger CSA cable.
The sub-board itself and any further protective devices for any sub-circuit after the 6A MCB will need to be
supplied by the installer.
6.5 Monitoring the backup loads
The backup loads to be monitored in normal grid operation must become part of the load measured circuits by
the sonnen system. To enable this the CT position and switchboard configuration must be installed in Setup 4
configuration.
