Hi
like to know the type of wire to connect between solar panels to inverter.

Do have 8pcs  500w each panels 12 pcs  250ah batteries and a 5.5kw rated hybrid  inverter.

The distance panel to inverter is about 135 feet using mc4 connects.

Awaiting your reply and thanks

    Bob,

    What are you using for the connection from the solar array to the battery bank (MPPT charge controller or GT Inverter or what)?

    Basically, need to know the Vmp-array / Imp-array configuration (x series * y parallel connections). What is the Vmp/Imp of the panel?

    For example, a 150 Vpanel max input MPPT controller, you can run Vmp-array ~ 100 VDC max, possibly more? (are you in Curaçao, Caribbean Sea?).

    For a Vpanel input of 600 volts, a Vmp-array of 400 volts or so is possible... Higher the voltage, lower the current, smaller diameter wire you have to use...
