Connecting a Signaler for Generators Without an Autostart Function


Qualified person

2049570060

Generators without an autostart function do not have electric starting devices. If you install a generator without an autostart function, you can connect a signal generator (e.g., signal lamp) to the multifunction relay of the Sunny Island inverter. As a result, the Sunny Island can signal when the generator is to be manually started and stopped.

Signal generator or generator control in a cluster

Slaves control the generator less reliably than masters do.

  1. Connect the generator control preferably to the master.
  2. In a multicluster system, always connect the signal generator to the master of the main cluster.

Connecting a Signal Generator to Signal a Generator Request (Example)

Requirements:

Cable requirements:

  • Copper wire
  • Conductor cross-section: 0.2 mm² to 2.5 mm²

Procedure:

  1. 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.

    1. When making the following connections, always insert a silicone tube Connecting Relay 1 and Relay 2).
  2. The default setting of the Sunny Island uses the multifunction relay Relay1 for generator requests. Therefore, connect the control cable to the multifunction relay Relay1 on the Sunny Island. Use the C and NO connections.
  3. If the multifunction relay Relay1 for generator requests is not available, connect the control cable to the multifunction relay Relay2 on the Sunny Island. Use the C and NO connections.
  4. If, with more than one Sunny Island, the multifunction relay Relay1 and Relay2 for generator requests are not available on the Master, connect the control cable to a free multifunction relay on slave 1 or slave 2. Use the C and NO connections.
  5. Enter the configuration Automatic generator request in the table of settings Setting the Functions of the Multifunction Relays).
