2.6 PV connection
PV panel selection
PV string is a connection of PV panels whose output voltage and current vary
under different illumination. And just like battery, the PV panel can be connected in
either series or parallel as per needed. Please consult the supplier of PV panel so
that the operational voltage and current fall within the allowed range of the inverter
as set out in the specification.
