4.1 Meter Box for Sunny Backup
The Meter Box for Sunny Backup is an optional component of the Sunny Backup system and is used
for transmitting data to increase the self-consumption of the PV power.
The reading heads on the PV production meter and grid feed-in and purchased electricity meter read
out data. The reading heads supply the Meter Box with this data. The Meter Box transmits this data
to the Sunny Backup. The Sunny Backup can regulate the charging and discharging of the battery for
increasing the self-consumption based on this data.
The Meter Box draws the electrical power required for the data transmission from a socket-outlet or
another alternative voltage source.
4.2 Type Label
The type label clearly identifies the Meter Box. The type label is on the right-hand side of the
