The Problem Of Solar Voltage Rise/Drop And How To Fix It
You cable it in after the main switch, and the whole place will be fed with a steady 225 volts. Your solar power system will see the same voltage and function as intended, however the line side/network supply voltage will be driven up to whatever is required to make the energy flow back to the network. Im a bit confused here.
