Had a phone call this afternoon from a customer that we had installed a PV system for a few months ago. We had fitted an SMA inverter and he said that the red light keeps coming on and the inverter displays the message 'Grid Disturbance' .
He said that inverter then keeps restarting but keeps getting the error message and commented that there was no problem with the electrical supply to the house as the lights were still working so I said I would call round later and have a look.
Got a phone call 15 mins later to tell me not to bother coming out.
It seems that some contractors were using a mini digger in the garden of the house opposite and had damaged an underground cable and my customer said that you could see sparks coming out of the hole in the ground.
That's what I call grid disturbance !
