Error 038	The back-up battery on the
Back-up battery	interface circuit board is
empty	empty.
Display is blank,	The display contrast is bad,
despite sufficient	because the temperature is
injection	high.
	The display circuit board is
	not supplied with electricity.
	The PV generator is (partly)
	covered with snow.

Have the battery (button cell) exchanged by a qualified person. The battery is on the LCD display circuit board.

That can happen if the ambient tempera- ture is high. As soon as the temperature drops, the display will work properly again. That does not affect the injection of electricity.

Make sure the ribbon cable between the display circuit board and the control circuit board is not loose. For this pur- pose, switch the Solar Inverter off, and disconnect the AC and DC supply. When doing so, please observe chapter 2.1 «Safety Instructions».

Clear the snow off the PV generator, or wait until it has melted.
