4.7 Reverse Current Protection
Every input area of the inverter is equipped with a diode as reverse current protection. A reverse
current between the input areas is therefore not possible.
If only input area A is used and the reverse current resistance of the PV modules is complied with, the
reverse current protection at input area A can be bypassed (see Section 6.7 "Activating and
Deactivating the Reverse Current Protection at Input Area A" (page 52)). Bypassing the reverse
current protection slightly increases the inverter efficiency.
The reverse current protection at input area B cannot be deactivated.
