Connection to the PV Panel (DC input)

With reference to "Table 1" in appendix
1. Make sure the maximum open circuit voltage (Voc)
of PV generator is less than "Max. open DCV"
UNDER ANY CONDITION.
2. PV generator strings must be evenly built, thus
employing only one model of PV modules and
having the same length.
3. Use MC3 (Multi-contact) or compatible connectors for the PV array terminals.
4. Connect the positive from the PV panel to the (+) terminal and the negative to the
(-) terminals. Each DC terminal is rated to a maximum of 20A
models having one MPPT and multiple input pairs, it is suggested to share the
input current evenly.
5. On inverters with more than one MPPT, it is possible to handle independent PV
generators, each of them is subject to the considerations from point 1 to 4, but PV
generators can be different each other.
In case one PV generator is connected to the inverter, the best efficiency is
achieved by using only two of the three MPPT in parallel if short circuit current is
less than 2x "Max. input current per MPPT". If it is greater, it is possible to use
all of the three inputs in parallel.
6. Use curves depicted in "Table 4" in appendix to perform correct PV generator(s)
design.
