I have installed 4kw (5kva) solar system at my home. I have 3 phase supply (3 single phase meters instead of one 3 phase connection, i.e 3 separate phases and 3 neutrals, These neutrals are combined at source end of utility company) from the utility company. when I shifted load of one kwh meter on the solar system, it worked nicely but when I connected load of other meter, the earth leakage CB installed at incoming from utility Co. was tripped. Please note that since utility company's supply is through single phase meters, only phase was shifted to the solar system, neutral was not shifted.
I want to know, how this issue can be fixed?
