Connecting the Battery Room Fan
Qualified person
If the charging current leads to the emission of gases from the battery, the battery room fan is switched on by the Sunny Island for at least one hour.
Requirements:
The technical requirements of the multifunction relay must be met ( > Technical Data).
Cable requirements:
Conductor type: copper wire
Conductor cross-section: 0.2 mm² to 2.5 mm²
Procedure:
The battery management of the Sunny Island inverter is able to control one battery room fan for each battery. The following options result for the connection:
Control a separate battery room fan for each battery.
Control one battery room fan for all batteries. This is only an option with multicluster systems.
Controlling a separate battery room fan for each battery
- Ensure that the battery room is sufficiently ventilated in the case of a malfunction of the multifunction relay.
- When making the following connections, always insert a silicone tube ( > Connecting Relay 1 and Relay 2).
- With single systems or single-cluster systems, connect the battery room fan to a multifunction relay.
- With a multi-cluster system, in each cluster, connect one battery room fan on one Sunny Island to any multifunction relay.
- Enter the configuration Battery fan in the table of settings ( > Setting the Functions of the Multifunction Relays).
WARNING
Danger to life from electric shock due to incorrect insulation
In the case of faulty insulation, supposedly de-energized parts or cables may be live. Touching live components or cables can result in death or serious injury due to electric shock.
Controlling One Battery Room Fan For All Batteries
- Ensure that the battery room is sufficiently ventilated in the case of a malfunction of the multifunction relay.
- When making the following connections, always insert a silicone tube ( > Connecting Relay 1 and Relay 2).
- Connect the battery room fan to one multifunction relay on one Sunny Island of the main cluster.
- Enter the configuration Battery fan in Multicluster in the table of settings ( > Setting the Functions of the Multifunction Relays).
