DIY PV System Installation -- Wiring The Enphase wiring diagram is here.. I did the wiring in this order: 1- The junction box at the PV array, wiring from PV array to the disconnect switch on the house, the disconnect switch, the wiring from the disconnect switch to the circuit breaker panel. Wiring of a PV Array | Solar365 Step one in PV array wiring is determining the battery voltage in use. Typical PV modules use 12V or 24V. The steps for increasing PV array voltage are series or parallel connection of the wiring modules which will increase current flow. Four 12V modules connected in series will generate 48V output.
