Solar Photovoltaic Power Inverter is Installed Outside the Bedroom Wall?

A.Photovoltaic inverters have radiation, but the photovoltaic inverter and  Solar Panel in Pakistan  itself is a bridge circuit composed of several switching tubes. The switching frequency is roughly in the order of kHz, which is far from enough to cause cancer. In fact, the electromagnetic radiation of photovoltaic inverters is similar to that of household appliances

Growatt photovoltaic inverters are similar to laptop computers. They are lower than electromagnetic cookers, hair dryers, and refrigerators. The impact on the human body can be ignored!

Solar Inverter Installation Diagram

Do not install the inverter in direct sunlight. Otherwise, it may cause additional internal temperature of the inverter, and the inverter will derate to protect the internal components. Even the temperature is too high to cause the inverter temperature fault.

The selected installation site should be strong enough to support the weight of the inverter for a long time.

The ambient temperature of the selected installation site is -25°c ~ 50°c, and the installation environment is clean.

The ambient humidity of the selected installation site does not exceed 95%, and there is no condensation.

There should be enough clearance in front of the inverter to make it easy to observe data and maintain.

Try to install it in a place far away from residents’ lives, and some noise will be generated during its operation.

Make sure that the installation place does not shake.

How to Install Photovoltaic Inverter

The inverter is a photovoltaic device, but also an electrical device. It consists of hundreds of components and is placed in the external environment all the year round. Pay attention to standard installation and operation, only when both are taken into account can the stable operation of the power station be guaranteed.

However, in actual photovoltaic projects, inverters are installed in various environments, and various irregularities abound.

So how to install a photovoltaic inverter is considered a standard? Here we consulted the technical service personnel of Souhang New Energy, a well-known domestic inverter company.

To sum up, the core keywords mainly include the following “wall surface, ventilation, sunlight, installation”.

First, the Wall Condition.

The power of the inverters used in the market ranges from 250W to 1MW, and most of the inverters installed at the household end in the distributed market are mainly in the range of 1-40kW. Take the 1-70kW parameters provided by Sofar New Energy as an example.

The weight of 1kW is 11kg, the weight of 40kW is 52kg, and the weight of 70kW is 70kg. When installing inverters of different weights on the wall, the first thing to consider is the condition of the wall, whether it can bear such a weight, so you need a Strong, load-bearing walls.

Second, Ventilation.

During the working process of the photovoltaic inverter, a certain amount of heat will be generated. If the heat cannot be dissipated, the life of the internal components of the inverter will be shortened and the power generation will be reduced.When installing the inverter, the user should try to choose a well-ventilated location, which can prolong the life of the inverter to a certain extent.

Third, Sunshine Conditions.

Most inverters have IP65 protection level, which does not mean that the inverter can really withstand the wind, sun, rain, and snow pressure, and the inverter also needs to be cared for. The inverter is made of Composed of many components, the life of components will be reduced under direct sunlight, so it is very important to avoid sunlight, wind, rain, and snow pressure.

Fourth, install.

There is a lot of knowledge when installing the inverter. For example, the machine should avoid direct sunlight, and enough heat dissipation space should be reserved on the top of the machine. There should be no accumulation of rain and snow on the top of the machine, and the machine should be kept at an appropriate distance from the ground.

Solar Inverter Installation Method

The beginning is the preparation work before wiring. Before the electrical connection of the photovoltaic inverter, it is necessary to ensure that the DC switch of the inverter is in the “OFF” state and disconnect the AC side circuit breaker. Otherwise, the high voltage of the inverter may cause the life danger of the operator.

Then each inverter has to be installed independently – an AC circuit breaker. Do not share multiple inverters. is forbidden to connect loads between the inverter and the circuit breaker.forbidden to use single-core wires at the output end of the inverter.

It should be noted that it is also necessary to connect the protective ground wire PE, one point must be connected to the protective ground wire PE, and the inverter is connected to the grounding bar through the protective ground wire PE to achieve the purpose of grounding protection.

It should also be noted that if the wire is relatively thick and heavy it is necessary to ensure that the output wire is well connected before turning on the inverter.
