Domestic panels produce 12 or 24 volts Phil, depending on how many individual cells are wired in series to make up the panel. The inverter bumps it up to 240 for domestic use.
Hey Geoff,
An inverter takes electricity that produces 'DC' electricity, such as solar panels or a battery system, and converts it into mains-equivalent 230 volt 'AC' electricity ready for use in your house or local usage.
You can back feed into a local transformer secondary winding for local usage but as I believe not into HV supply.
It’s like pissing in the Ocean.
The little voltage PV systems produce is highly effected by voltage loss over distance.
Cheers Phil.
