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 utility per channel
/ MPPT is indicated on the DC circuit breaker and on the type plate on the side of
the PIDbox utility. Make sure this is never exceeded.
Make sure the PV arrays are connected to the "PV in A" and "PV in B" side of the
Ilumen PIDbox utility, NEVER to the "INV out A" or "INV out B" side.
