D)
Before connecting PV panels to DC terminals, please make sure the polarity is correct . Incorrect polarity
could permanently damage the unit. Check short-circuit current of the PV string. The total short-circuit
current of the PV string should be less than the inverter's maximum DC current.
E)
Connect the positive and negative terminals from the PV panel to positive (+) terminals and negative (-)
terminals on the PV inverter.
F)
High voltages exist when the PV panel is exposed to the sun. To reduce risk of electric shock, avoid
touching live components and treat connection terminals carefully.

Commissioning checks
A)
When the PV panels are connected and their output voltage is greater than 100 VDC but the AC grid
is not yet connected, the LCD display shows the following messages in order: "RADIUS Home - APV
Inverter"-> "No AC connection" and the LED will be red.
B)
Close the AC breaker or fuse between the PV inverter and the grid. The normal operating sequence
begins (it take 30 seconds).
C)
Under normal operating conditions the LCD displays "Power: xxxx.xW". That is the power fed to the grid.
The LED turns green.
D)
This completes the check.
