NOTICE
• Strictly follow the preceding sequence. Otherwise, the product may be damaged, and
the loss caused is not covered by the warranty.
•
If the DC side is powered up while the AC side is not, the inverter indicator may turn
red, and the inverter will report a fault named “Grid Power Outage” (the fault informa
tion can be viewed on the iSolarCloud App, see “Records” for details). The fault is
automatically cleared when the AC circuit breaker between the inverter and the grid
is closed.
•
Before closing the AC circuit breaker between the inverter and the power grid, use
a multimeter that is set to the AC gear to ensure that the AC voltage is within the
specified range. Otherwise, the inverter may be damaged.
step 3 Connect the DC switch (if there is) between the inverter and the PV string.
step 4 Set initial protection parameters via the iSolarCloud App. For details, please refer to 7.2 Installing
App,and 7.4.2 Login Procedure. If the irradiation and grid conditions meet requirements, the inverter
will normally operate.
step 5
Observe the LED indicator to ensure that the inverter operates normally. Refer to 2.4 LED Indicator
for details.
WARNING
It is strictly forbidden to close the DC switch (if there is) if the inverter is in grid-connected
status. Otherwise, the inverter may be damaged due to the lack of insulation impedance
detection, and the loss caused is not covered by the warranty.
