5.4 PV Connection

There is a risk of inverter damage! The following requirements should
be met. Failure to do so will void guarantee and warranty claims.
 Make sure that the maximum short circuit current of each DC input is
less than inverter allowable limit.
 Make sure that the maximum open voltage of each string is less than
600 V. Voltage over 600 V can damage the inverter.
 Make sure that the impedances between the positive terminal of the
PV string and Earth, and the impedances between the negative
terminal of the PV string and Earth are larger than 200 kΩ in any
case.
