* Depending on the connected battery.
** Can be reached only if PV and battery power is sufficient.
*** Only when the DC switch is set to "ON", the DC Type II is able to provide effective protec-
tion against electrical surges.
Note:The output voltage of strings should all exceed the lower limit of the full load MPPT
voltage range. The difference in string voltage between different MPPTs should be less than
150V.
