Hi,
I'm in a process of adding a battery and few more solar panwla to my existing grid tie house solar using Easysolar-II GX.
Due to lack of certificate for operation on the Irish grid I need to install an anti-islanding device between the grid and the inverter. Since that is the case, I've decided to build the anti-islanding device in such a way that it will disconnect the whole house in the event of grid failiure. When that happens, I will then use a manual transfer switch to connect the whole house to the EasySolar-II essentially going off-grid while it's down.
This way I don't have to rewire the whole house and still use all the appliances.
What I'm curently not sure about is whether I should put the ET112 meter before or after the anti-islanding device (before meaning between the grid and the anti-islanding device).
Any thoughts?
