Error 027	The grid voltage is too high.
Grid overvoltage	The Solar Inverter monitors
3-phase	the lower and upper admis-
	sible grid voltage limits in
	3-phases. If the voltage
	exceeds the upper limit
	(Umax = 264 V), the Solar
	Inverter will automatically
	switch off and will only
	restart when the voltage
	value drops below the
	upper limit again. The shut-
	down can already be trig-
	gered if the voltage rises
	above the upper limit for
	a short time.

Ask your power supply company about the stability and design of the grid.
