How do you turn on a PV inverter?

Switch the grid supply main Switch (AC) ON first. Switch the DC switch ON. If the voltages of PV arrays are higher than start up voltage, the inverter will turn on. The red LED power will be continuously lit. When both the DC and the AC sides supply to the inverter, it will be ready to generate power.

Do Canadian Solar inverters have OCPD ratings?

To protect the inverter's AC grid connection conductors, Canadian Solar recommends installing breakers that will protect against overcurrent. The following table defines OCPD ratings for the Canadian Solar Three phase inverters. There are 3 communication terminals for Canadian Solar inverter. COM1-COM3 are all for RS485 communication.

Can a PV inverter be electrically isolated?

DC input and AC output must be electrically isolated before operation. DO NOT connect PV array positive (+) or negative (-) to the ground. To do so may cause serious damage to the inverter. Electrical installations must be done in accordance with the local and national regulatory and electrical safety standards. 2. Safety Instructions 3.

What size wire should a Canadian Solar inverter use?

If the wire is longer than 20m, it's recommended to use 25-35mm cable. Refer to local electrical codes for wire sizing. Canadian Solar three phase inverters integrate neutral connectioin point. However, with or without neutral connected won’t affect the normal operation of inverter itself.

Do Canadian Solar three phase inverters integrate neutral connectioin point?

Canadian Solar three phase inverters integrate neutral connectioin point. However, with or without neutral connected won’t affect the normal operation of inverter itself. Please refer to the local grid requirement for if need neutral cable connected. The ground wire can be connected to the grounding hole on the right side of the inverter heat sink.

How to connect a DC inverter?

Screw up the cap nut to the connector housing. Torque to 2.5-3Nm (as shown in Figure 5.15). v) Connect the finished DC cables to the inverter. A small click will confirm connection as shown by the red area in Figure 5.16). 2 For all AC connections, 16- 35mm 105 °C cable is accept to be used.
