Installation Manual Ilumen PIDbox Mini v1.5
6.2 SOLAR ARRAY AND INVERTER (MPPT) CONNECTIONS
When installing the PIDbox mini between the PV array and inverter always switch
off the DC switch of the inverter
When doing any kind of work on the PIDbox mini, always disconnect the DC
power plug from the device before unplugging any PV-cables.
Always connect the PV arrays to the PIDbox mini. On the Ilumen PIDbox mini the “A pv in +” plug
should be connected to the positive side of the strings of the 1
st
MPPT and the “A pv in –“ plug
should be connected to the negative side of the strings of the 1
st
MPPT. The strings of a 2
nd
MPPT
should be connected in the same manner to the “B pv in” plugs. Next connect the inverter.
Connect the “A inv. out +” plug of the Ilumen PIDbox mini to the positive input of the inverters 1
st
MPPT. Then connect the “A inv. out –“ plug to the negative input of the 1
st
MPPT of the inverter.
If “B pv in” is used connect the “B inv. out” plugs in the same manner to the inputs of the
inverters 2
nd
MPPT.
All unused inputs and outputs have to be terminated with a corresponding sealing plug.
If you work with inverters with multiple MPPT’s you cannot mix the PV arrays
from multiple MPPT’s.
The maximum current that can pass through the Ilumen PIDbox mini is 20A per
channel / MPPT. Make sure this is never exceeded.
Make sure the PV arrays are connected to the “A pv in” and “B pv in” side of the
Ilumen PIDbox mini, NEVER to the “A inv out” or “B inv out” side.
