Solar Panel Electrical Wiring
Assemble The Solar Panels and run cable thru the cable glands on the bottom of the enclosure.
Do not connect PV cables to the controller yet, it is recommended to connect the battery first.

First connect PV1 Positive (Male) MC4 Connector to PV2 Negative (Female) MC4 Connector.
Repeat for PV3 and PV4 creating two sets of two in a parallel configuration.
Next, configure the two sets of two in a series.
Connect PV1 and PV3 Negative Connectors to the MMF MC4 Adaptor, you will need to use one of
the 8' MC4 Male to Female cable Extenders for either PV1 Negative or PV3 Negative connections.
Connect PV2 and PV4 Positive Connectors to the FFM MC4 Adaptor, you will need to use one of
the 8' MC4 Male to Female cable Extenders for either PV2 Positive or PV4 Positive connections.

The Kit will include a pair of 15' 600V PV Cable with a Male and Female MC4 Connector. Attach
them to the FFM and MMF MC4 Adaptors then run the other end of the cable into the enclosure.

half creating two 15' cables.
Please reapply the Twist Nut to the open end of the cables to prevent a short.
