4.1 Start Up
The inverter will start up when the following conditions are satisfied:
1. Grid voltage and frequency are within nominal setting.
o
240V settings: Grid voltage at start-up must be between 216V
and 254V
o
208V settings: Grid voltage at start-up must be between 187V
and 220V
o
Grid Frequency must be between 59.5Hz to 60.3Hz
2. PV array voltage is greater than 200V on any one of two MPPT channels.
4.2 First-Time Start Up
During first-time start up, the inverter will prompt installers to choose various
setting options to match grid conditions and to configure i
nverter’s communication
options.
The installer can go back to the configuration screens by pressing
all three keys
(Up, Down, and Enter) at the same time for 5 seconds
. After holding these
keys for 5 seconds, the inverter will stop exporting power to the grid and allow the
installer to choose the setup options as if it were the first-time start up.
INSTRUCTION:
After first-time start up, the inverter will not go through these
configuration steps in subsequence start-ups. Inverter will go directly
through start up sequence.
