(Warning) Your solar inverter is designed
for an ambient temperature of
up to +40°C. When a specified
temperature threshold of the
heat sink is reached, the output
power is reduced linearly.
Should the heat sink tempera-
ture nevertheless continue to
increase, feeding is stopped.
This warning appears when the
current heat sink temperature
is just below the switch-off
threshold. The maximum permissible
ambient temperature has been
exceeded.
