In a solar PV system, a solar inverter (or solar panel inverter) is essentially the gateway between your panels and your home. Any electricity that your panels generate must pass through this corridor before it can be used to power your premises. But what's the point of this middle man?

If you're getting a standard string inverter for residential solar panels, the cost will typically range from £500 to £1,000, depending on the size of your system. Meanwhile, microinverters.
