Are you looking out for a solar grid-tie inverter, but don’t know how to choose the best one?
Well then, Enertech, the leading solar charge controller and battery charger suppliers, brings this blog to you, serving you as a step by step guide.
It will take you through all the elements you must consider before buying a solar grid-tie inverter.
The Criticality of Solar Grid-tie Inverters
A solar grid-tie inverter is connected to the local utility grid. It sends the power the solar array generates back to the local power grid.
A solar grid-tie inverter takes direct current generated out of the solar photovoltaic panels (PV) panels. It then transforms it into alternating current (AC), which is the usable form of energy. The inverter sends the AC to the local power grid, which then powers your home.
In the above mechanism, it is necessary to connect the solar energy system to the local power grid through the electricity meter. Doing so will earn you credit that the local electricity board will pay you for generating some energy.
A solar grid-tie inverter, therefore, is a critical device. Hence, you must be careful while buying it.
5 Factors to Consider while Buying a Solar Grid-tie Inverter
- IP Rating of the Inverter
The IP rating is the Ingress Protection Rating of the inverter.
Inverters are subject to harsh natural elements such as water, dirt, dust, high temperatures, low temperatures, fluctuating voltages, etc.
The IP rating of the inverter signifies how resistant your inverter is to all the above factors.
It is a two-digit number, wherein each increasing digit denotes the level of protection.
- Output Waveform
Based on the circuit design, inverters generate outputs with various waveforms like square wave, sine wave, modified sine wave, etc.
However, an inverter producing a true sine wave must form your choice.
Why? That’s because a true sine wave is more energy-efficient while powering inductive loads, as compared to other waveforms that use 20% more energy.
Excessive utilization of energy may result in, and it may affect the working of your appliances in the long run.
- Efficiency of the Inverter
An inverter’s efficiency is all about the power it takes from the solar panels, and converts into usable AC power. An efficient inverter reduces the loss of energy that usually happens while receiving DC from the solar panels.
An efficiency of 50% indicates that the inverter is using very less amount of power. On the other hand, an efficiency of 90% denotes maximum utilization of energy, and which is considered to be the inverter’s rated output.
Most of the solar grid-tie inverter manufacturers offer a peak efficiency value. Peak efficiency value is the highest efficiency that the inverter can achieve.
- Power Consumption
Power consumption constitutes an essential element of the solar inverter you buy.
The efficiency of the charging segment determines the power consumption of your solar inverter. An inefficient charging element will lead to wastage of electricity, even after fully charging the battery.
- Battery Backup Duration
Duration of the battery backup is an important consideration. It determines for how long the inverter will serve when you start using it. Ensure that you check the battery backup before making a choice.
- Choose the Best Vendor
There are many solar inverter, solar charge controller and battery charger suppliers out there in the market. Hence, choosing the best may turn a challenge.
So, while choosing the best vendor, ensure that the vendor services right from selling the product to installing, and further maintaining it.
Besides, it is necessary that the vendor offers after-sales service though a technical team to resolve routine concerns if any. Elements such as warranty as well matter a lot.
