What is Inverter Islanding?
This is better understood as a function of the electricity grid. If the grid fails or is turned off the inverter will automatically disconnect itself from the grid. If the grid fails and the inverter remains active attempting to feed electricity into the grid – it can be dangerous – This is known as Naturally, this must be prevented from happening for obvious reasons. Where there are multiple arrays, spread across buildings within the same area, for example, this could be a problem. Inverter electronics are very sophisticated and operate within very fine tolerances. Exceeding this tolerance ensures that the inverter will cease to operate. Grid Tie Inverters Grid connect inverters convert the DC produced by solar array into AC required by the electricity grid. The inverter can convert into single-phase or three-phase AC at the frequency and voltage required by the grid. Inverters for use in the UK are referred to as G83 compliant. There are few variations of grid connect inverters and c
