Illustration 2.21 Incorrect Parallel Connection
1
Parallel jumper
2
Parallel connection, 1 input. Current in first input is
exceeded, thus overloading cable and PV load switch.
3
Parallel connection missing. All PV power feeds into one
input, thus risking overload of PV connector, cable and PV
load switch.
4
Parallel jumper missing, thus risking overload of PV
connector, cable and PV load switch in the event of inverter
failure.
