User instructions
The Solar
+
Plus by default steps down the load on start-up. The green
status light displays to demonstrate this. On start-up the Solar
+
Plus will
assess the incoming voltage. If the incoming voltage is below 253V on start up
and remains below 253V for 5 minutes, the Solar+Plus will disengage and go
into standby mode. The red status light displays to demonstrate this.
NOTE: On installation of the Solar
+
Plus, it will go into start up mode.
On start up the System will step down the incoming voltage for
5 minutes.
The green status light will be illuminated to demonstrate this, if the
incoming voltage remains below 253V for the entire 5 minutes the
Solar
+
Plus will then enter standby mode, the red status light will then
illuminate. Check to ensure the Solar
+
Plus does enter standby mode.
In the event the Solar
+
Plus detects a supply voltage greater than 253V the
internal relay will de-energise and disconnect the PV inverter from the
supply. The relay will remain de-energised until the Solar
+
Plus detects the
supply voltage has dropped below the threshold voltage and remained there
for 5 minutes.
The Solar
+
Plus can be visually identified as being energised or
de-energised by the indicating status light.
When the Status light shows as red, the Solar
+
Plus is energised and in
standby mode.
When the status light shows as green, the Solar
+
Plus is de-energising the
incoming mains supply to the PV inverter.
