I have a 4kWp solar system with a Sunnyboy inverter on the roof facing almost directly south - this is on the house
I also have 30 or so kWh of batteries off two luxpower inverters installed in the very nearby but unattached garage each capable of about 3kW - so 6kW in total. These batteries are AC coupled. This is about a days worth of power given I have a high electricity use for a variety of reasons.
I have 16mm SWA between the house and the garage to charge and discharge the batteries
There is an EPS circuit in the garage to a twin socket for the freezer in the garage.
I recently had a powercut which essentially turns off the solar and the batteries - its a safety design that I understand why - so no issues there. I have a 100amp main fuse which popped when I was pulling about 40 amps (estimated). Apparently it was quite badly burnt and the fitting was a bit loose. Anyway all working now with new fitting
My question is how can I go about setting things up so that I have power (as delivered by solar and batteries) in the event of a powercut even if its a manual switchover.
AIUI I would need:
1. An Isolator to prevent me feeding anything back into the mains (although there exists a practical issue of fitting that to the equipment board - a lack of space, but that can be solved [somehow])
2. Something to generate the signal that the mains generates - I assume a 50Hz(?) signal so the equipment I have thinks its connected
Any ideas?
