Product Introduction
A solar PV micro-inverter is a device that converts direct current from a single solar module to alternating current.
The microinverter converts DC power from a single solar module to AC, and each solar module is equipped with an inverter and converter function, so that each module can be converted to current individually, hence the name “microinverter”.
Microinverters have the advantage of being able to achieve maximum power point tracking (MPPT) at module level, which is an advantage over centralised inverters. This allows the overall output power to be maximised by optimising the output power of each module.
In addition, in combination with the communication function, it can be used to monitor the status of individual modules and detect faulty modules.
Correct installation location
Avoid sunlight – when installing an inverter, you need to avoid direct sunlight to cause excessive temperature
Avoid rain – the installation of the inverter needs to prevent rain or other liquid from getting wet or soaking
Keep ventilation – the inverter needs to be installed in a well ventilated environment to facilitate heat emission
How to install?
Step1：
install the inverter on the bottom of the solar panel. Note that it must be ventilated and dry. Cool environment.
Step2:
Connect the two DC terminal of the PV to the inverter,positive to positive, negative to negative MC4 connector
Step3:
Connect the AC output cable to the household outlet. The household outlet switch must be turned on.
Regarding the heating problem of the inverter
This is normal phenomenon. All electronic devices generate heat during operation.
The QR series inverter uses an aluminium alloy casing for better heat dissipation. The body of this inverter has been designed to be in contact with as much air as possible all around, physically cooling it by the fast flow of air.
The inverter also has over-temperature protection if the temperature is high. Then the inverter will automatically reduce the working output efficiency. Or stop working. After cooling down, restart. It is recommended to install the inverter in a ventilated, dry and cool place.
In order to keep the heat low, the inverter will stop generating power or reduce the amount of power it generates by “derating” as it passes programmed temperature milestones or you can state this as ramp down of power.
