What are CSI solar inverters?

CSI Solar‘s grid-tied, transformer-less string inverters help to accelerate the use of three-phase string architecture for industrial and commercial rooftop applications. These inverters are modular design building blocks that provide high yield and enable significant BoS cost savings.

What is a goodwe SMT 50-60 kW inverter?

GoodWe SMT 50-60kW Series inverter is ideal for medium and large-scale commercial installations. Harvest solar energy and generate environmental-friendly power for increased return on investment brought by high yields with your commercial PV system.

How to isolate a PV inverter from a reverse polarity meter?

Turn DC Switch OFF 2. Open Fuse holders to isolate PV strings 3. Use meter to find out which PV string is connected in reverse polarity 4. 2. Restart inverter by turning both AC and DC switches OFF. Wait for 1 minute for all energy to discharge and turn both switches ON 3.

How to set up a PV inverter?

Switch the Inverter’s DC Switch to the “ON” position. When the energy supplied by the PV array is sufficient, the LCD screen of inverter will light up. The inverter will then start up with the message “sys checking”. When the inverter completes “Initialization”, the LCD will show the screen as Figure 5-1 below. 4. Setting Language.

How many RS485 inverters can be connected?

When the inverters are monitored via the RS485 communication, a unique RS485 address for each inverter can be set up through the LCD interface. Up to 32 inverters can be connected in the RS485 communication network.

How do you test a PV inverter?

Open fuse holders to isolate PV strings. Test strings with string test set. Add one PV string at a time, and start up inverter to see if alarm occurs. If no alarm, turn OFF AC switches to disconnect from grid and add the next string. Turn AC switch on and start up inverter again Continue until you can find the string that triggers the alarm.
