Installation
Table 2 DC Voltage Limitation
Figure 10 Multi-string input connection (Left) and common-string input connection (Right)
Ensure that the DC side is not charged before installation and maintenance. But
after DC side is disconnected, the capacitor is still charged, so need to wait for 5
minutes to ensure that the capacitor is fully discharged.
Before the electrical connection, make sure to use opaque material to cover the PV
battery or disconnected the breaker of DC side. Exposure to the sun, PV array will
produce a dangerous voltage after sun exposure.
Ensure that not connect each PV module to the DC/DC power optimizer, or the inverter
would not function normally.
5.7 Connections of the PV Power System
5.7.1 Announcements
5.7.2 PV array Connection Types
PV array connection types: There are 2 independent MPP trackers in inverter. You can choose common
-string input connection and multi-strings input connection. We recommend that choose multi-strings to
harvest max. PV power.
Please select excellent function and reliable quality PV arrays. Open-circuit voltage of PV arrays should
be<Max. input DC input voltage. Operating voltage should be conformed to MPPT voltage range.
