I have just installed a 2 phase system with 2 Solar Edge inverters (3.7kW per phase) Each pv system is fed through a shared Elster A1100 3 phase meter and each one runs fine on its own. When connected at the same time the RCDs on both system trip. The only way I can make it work is to bypass the generation meter, so the problem appears to be at the meter. We have done many single phase installations, and could use 2 single phase meters, but that requires two FIT applications, which seems mad!! Anyone got any ideas?
