Power from Alternate Sources
You can use an alternate power source to supply the SMA Power Injector with Bluetooth
with power. Observe the following requirements for the power source:
DC Source Requirements
• Output voltage: normally 12 V … 24 V DC ± 20 %
• Output power: minimum 2 W
• Cable cross-section: > 0.1 mm
2
• Maximum cable length: 10 m
AC Source Requirements
• Output voltage Ueff: 12 V … 24 V AC eff ± 10 %
• Output power: min. 2 W (plug-in power supply: min. 2.5 W)
• Cable cross-section: > 0.1 mm
2
• Maximum cable length: 10 m
To connect the SMA Power Injector with Bluetooth to an alternate power source, proceed as follows:
1. Connect the cable of the alternate power source to the plug connector included in the delivery.
2. Insert the plug into the connection terminal of the alternate power supply for the SMA Power
Injector with Bluetooth.
☑ The SMA Power Injector with Bluetooth is connected to the power supply. The "RDY" LED glows
green continuously. It takes about one to two minutes for the Sunny SensorBox to start up once
it is connected to the power supply. The blue Bluetooth LED on the SMA Power Injector with
Bluetooth glows continuously. Following initial startup, it can take three to four minutes before
the Sunny SensorBox is ready for use.
– If the "RDY" LED on the SMA Power Injector with Bluetooth does not light up or flash, refer
to section 11 ”Troubleshooting” (page 68).
– If the blue Bluetooth LED on the SMA Power Injector with Bluetooth does not glow
continuously, refer to section 11 ”Troubleshooting” (page 68).
The startup procedure of the Sunny SensorBox is complete. You can now detect the Sunny SensorBox
with a communication product (e.g., the Sunny WebBox with Bluetooth or Sunny Explorer) and view
the data collected by the sensors.
NOTICE!
Damage to the SMA Power Injector with Bluetooth caused by excessive voltage.
Any power source that is technically unsuitable can damage the SMA Power Injector with
Bluetooth.
• Closely adhere to the requirements of the alternate power source or simply use either
the plug-in power supply accessory that comes with the SMA Power Injector with
Bluetooth or the power module from SMA Solar Technology AG.
