On-grid PV inverters

Grid-connected inverters convert the direct current produced by your solar panels into sinusoidal alternating current. The inverter synchronises its output current to the 50 Hz frequency of the public grid and adapts its output to voltage variations (ideally 230V). In the event of a grid failure or power surge, the grid inverter disconnects.

Choose in 30 seconds

  • Your objective: self-consumption/feed-in without a battery → grid-connected inverter.
  • Single-phase or three-phase: check your electrical installation before choosing.
  • MPPT: the more orientations/constraints you have, the more MPPT counts.
  • I confirm: estimate PV production and power using the Solar Simulator.

FAQ - Grid-tie inverters

1. What is a grid-tie PV inverter used for? +
It converts the panels’ direct current (DC) into usable sine-wave alternating current (AC), synchronized with the public grid.
2. How does the inverter synchronize with the grid? +
The page states that it synchronizes its output current to the public grid frequency of 50 Hz.
3. What happens if the grid voltage varies? +
The inverter adapts its output to grid voltage variations (ideally 230V, but variable).
4. Does a grid-tie inverter keep working during an outage or overvoltage? +
No: in the event of a grid outage or overvoltage, the grid-tie inverter disconnects.
5. What’s the difference between a grid-tie, hybrid and micro-inverter? +
A grid-tie inverter converts and injects/supplies without a battery. A hybrid inverter also manages a battery, and micro-inverters optimize panel by panel.
