Before you connect up the solar panels you should check that the voltage specified by

the manufacturer corresponds to the actual measured voltage.

When you measure the voltage, you should bear in mind that when the temperature is

low and the insolation is constant, the open-circuit voltage generated will be higher.

If the outside temperature is -10°C, the open-circuit voltage for the solar panels should

never rise above 530 V. The relevant temperature coefficients for calculating the theore-

tical open-circuit voltage at -10°C can be found in the data sheet for the solar panels.

If the open-circuit voltage for the solar panels rises above 530 V, this will result in com-

plete destruction of the FRONIUS IG and all warranty rights shall be declared null and

void.
