How to connect Chint photovoltaic inverter

What is a PV string inverter?

To avoid any other unforeseeable risk, contact your dealer immediately, if there is any issue found during operation. 2.1.1 Function This series is a single-phase grid-tied PV string inverter (transformer less) that converts the DC power generated by PV strings into AC power and feeds the power into power grid. The inverter is transformerless.

How does a DC inverter work?

The inverter converts the DC from PV modules to AC with the same frequency and phase as the AC grid. All or part of the AC power is supplied to local loads, and the surplus power is supplied to the electricity grid. DC power distribution equipments AC Grid B id rect onal electric meter AC power distribution equipments

How does a PV inverter work?

At the same time, it will also check whether the DC input of PV modules is sufficient. The inverter will turn into normal operation mode when both of AC and DC conditions are fulfilled. The inverter will disconnect from the power grid and switch to standby mode when the sunlight is weak and power generation is small.

How do I install a PV inverter?

Ensure there is no electronical connections around ports of the PV inverter before installing; Adequate ventilation must be provided for inverter installation location. Mount the inverter in vertical direction, and ensure that no object is put on the heat sink affecting the cooling. (For details, refer to Chapter 4 Installation)

How do I turn off a PV inverter?

Move the cursor to submenu “Turn ON/OFF”. Move the cursor to “Turn OFF” and ensure, then the inverter will be shut down. Automatic Turn ON/OFF: The inverter will start up automatically when the output voltage and power of PV arrays meet the set value, AC power grid is normal, and the ambient temperature is within allowable operating range.

How to connect a PV module to a DC inverter?

PV modules generate electric energy when exposed to sunlight and can create an electrical shock hazard. Therefore, when connecting the PV modules, shield them with opaque cloth. Before connecting DC input power cables, ensure that the voltage on the DC side is within the safe range and that the DC SWITCH on the inverter is OFF.
