Installation Instructions 23
5.4 Startup
After completing the mechanical and electrical installation, the inverter is put into
operation as follows:
1. Switch on the DC and AC breakers.
2. The inverter starts up automatically when DC-power from the PV generator is
sufficient. There are three normal states during its operation:
Waiting: When DC voltage of PV generator is greater than 125V (minimum startup
voltage) but lower than 150V (minimum working voltage). The inverter waits for
sufficient power.
Checking: When DC voltage of PV generator is greater than 150V, the inverter is
checking feeding conditions.
Normal: After checking, the inverter operates in the normal state, and the green LED
light up. Meanwhile, it feeds power into the grid, and shows present power in LCD
display.
As long as the inverter working, it tracks the maximum power from your PV modules
(MPPT) in any condition.
The inverter automatically stops when the PV power is not enough.
Notes：
If the inverter is in “Fault” state, look over the FAQ part in
operating manual.
5.5 Communication
A PV system with inverters can be monitored in different ways. Eversolar New
Energy provides you RS232 and RS485.
5.5.1 Communication through RS232
The current data of the PV inverter can be transmitted to PC through RS232 interface.
The maximum length of the cable for RS232 is 10 m. In addition, the firmware can be
