the network

inverters will
become quite
popular.
In these days when steps are being taken to get the Roof Market moving and the Solarex
Istanbul fair is approaching the correct inverter selection will provide you with advantages
in terms of investment costs and more importantly enable you to choose the best product
for your needs. What I will explain in this article will determine, more accordingly to your
needs, the working principle of a solar inverter, independent from brand and model.
No matter what the brand is, the most important thing is first to find the product that best
suits your objective. Then it is time to assess different criteria such as the solar inverter
quality, price performance rate, the satisfactoriness and fees of the tracking system and
the sufficiency of the after sales services. The solar devices you can buy on the market are
devices with or without main connection, hybrid products that have capability for both and
the micro solar inverter models that are gradually growing.
Let’s get an idea by using scenarios; you may be interested in solar energy as a hobby and
want to understand a system without losing too much money from your own pocket. In
this case you may start out with one panel or a micro inverter, and then you can integrate
a monitoring system and see how much revenue it will earn you. If you want storage to be
involved you can acquire 220 Volts in a place with no electricity with a panel battery charge
unit and a small inverter.
After the idea to sell electricity and earn money emerged and steps were taken to get the
market moving, the network connected inverters will become quite popular because by
using these devices you will be able to supply your own power and sell the surplus to the city
main. It will be beneficial to find out about these types of products and especially how the
after sales procedures play out according to your own personal scenario, whether there are
technical support lines or calling centers, what the warranty period is and what the warranty
covers. In addition to all these you may want to use the power you have stored throughout
the day at night and in this case there are models not connected to the main and hybrid
models that will make your task easier. Hybrid solutions draw attention as compact, easy to
install and goal directed products for a home. Especially when we consider the longer life
of lithium ion batteries compared to conventional or gel batteries, these devices stand out as
price performance products. Maybe the most important question (my favorite) concerning
hybrid inverters at the fair will be what happens when the power goes out as I am playing a
game on the game console? Does the product you have bought function as an interrupted
power source or is it cut off at certain intervals? No one wants to lose power during the most
exciting part of the game; on the other hand the technology of batteries is very important.
Lithium ion batteries, just like other batteries, are divided into sub types. It is very important
to find out what technology has been used.
In a different scenario you can operate a main connected system with a system not connected
to the main in integration, or in other words you will be creating your own hybrid system.
The best advantages to this are they can operate like ups and eliminate electrical outages in
such a short time we can’t even notice it (the game won’t be interrupted) and because they
supply your power primarily with the main connected inverter the rate of using batteries
is reduced thus extending battery life. Supplying or not supplying power to the main can
be opened and closed according to your preference here. Especially consumers, who are
trying to sell power without having a bi-directional meter installed (which is wrong), can
avoid the bad surprise of high bills by sending zero power to the main until they complete
the documentation process. Otherwise they may get extremely high bills to pay rather than
earn money.
Even if you are going to install a small system or have a small system installed, knowing the
properties of the materials being used and how the devices will behave on a basic level will
be to your advantage. Attending informative seminars and courses on this subject may give
you a different perspective before purchasing any products.
