Power limitation

When the battery voltage is lower than 50Vdc, the output power will be reduced. If the connected load is greater than this reduced power, the AC output voltage will decrease until the output power reduces to this reduced power. The minimum AC output voltage is the output voltage setting – 1 0V.
