i have been asked to install a 9.90kw system on a large roof, which has a 3 phase incoming supply, i have done single phase domestic systems, but never a 3 phase one:
please can explain:
do i need to split the 9.90kw over 3 strings and have a string a phase,
is there one inverter (model number please) or will i need 3 separate inverter,
what fits rate would this come under, would it be 9.90kw or because it is over 3 phases would it be 3.30kw so they would get 41.3p per kw
