2.4 PV (solar) string
Selection of PV panel
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.
Please do not use PV panel which requires one terminal
connected to ground (e.g. thin-film panel).
Connect the PV strings
As the PV string generates power as long as illumination exists,
a circuit breaker shall be installed between the PV string and
inverter so that the power from PV string can be switched off
when needed (e.g. regular maintenance).
To ensure better contact and reliability, ring terminal shall
be fit on the cables from PV string before connecting to
the inverter. The recommended size of ring terminal is
