    Where are you doing the install? Malaysia?

    And what brand/model of GT Inverter and solar panels (quantity/Vmp/Imp ratings, etc.)?

    Do you have a local building code there--Or will following the US/North American National Electric Code (NEC) be OK?

    What is your utility power (230 VAC 50 Hz, single phase?)?

    Will you have a chance of lightning strikes in the area?

    And will you have to get approval/stamps from a civil engineer for mounting systems (and will you have heavy winds to contend with)?

    Is your wiring US (American Wire Gauge--AWG or will it be metric rating and European wire/insulation ratings)?

    yes, im about to install it in Malaysia.
    im using SMA Sunny Boy 5000TL inverter.
    the building is a house. terrace houce.
    the system is 240V, 50Hz single phase
    lightning strike is not that high but the chance are still there.
    the mounting system is yet to be conformed. the wind here is not that heavy, not as heavy as in US. sometimes the wind is heavy, more than 20mph.
    the wiring will be in metric rating

    The free Sunny Design tool could help you out with the electrical aspects, e.g. how many panels in a series string, how many parallel strings, wire length etc.

    We still don't know which solar PV panels you're using, what orientation they'll be at, if there's shading or how many panels they are, so it's difficult to provide any detailed advice.
