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.

When asked about the role of a charge controller, an expert associated with a leading company that fabricates servo stabilizer Pune described the device as an essential part of a solar power harnessing system.
It is instrumental in the proper charging and discharging of the batteries, thus assisting them to remain operational for more extended periods.
But how to choose one that is suitable for one’s needs?
Well, one would need to keep in mind a few things when they are choosing a charge controller.
It is time to take a look into some of them in the following sections:
Be careful while choosing the voltage configuration
In the opinion of experts associated with leading servo stabilizer manufacturers in India like Enertech UPS Pvt. Ltd., it is best to select a charge controller that is capable of handling the voltage output of the system.
Charge controllers are made available by leading manufacturers in the following configurations:
- 24V and
If one has a solar power harnessing system that generates 12 volts of peak power output, then they would need to invest in a solar charge controller that can handle 12 volts.
On a lighter note, one can always go for a charge controller that can handle the maximum power output i.e., 48V, in case they have plans to upgrade their solar power harnessing system in the near future.
An ideal solar charge controller Mumbai should have the following features:
- It should come with an advanced microprocessor control unit that can automatically detect voltage and act accordingly by adjusting its internal workings in real-time.
- It should come with a buck regulator that would allow it to be used in solar power harnessing systems with a full power output range.
- It should be able to protect the system in case the polarity is reversed due to a fault in the system.
- It should be able to protect the battery unit(s) from both overcharging as well as discharging prematurely.
Type of the solar charge controller
Charge controllers are primarily of two types:
- MPPT (Maximum Power Point Tracking)
- PWM (Pulse Width Modulation)
Among the two types mentioned above, it is best that one chooses the MPPT type charge controller since PWM type controllers don’t even come close to its counterpart in terms of efficiency.
Size of the solar charge controller
Choosing the right size of the servo stabilizer is very important and pretty comfortable at the same time! It is best to choose one that is
large enough to work with the amount of current and power a solar power harnessing system is producing at any given point in time.
If one is on the hunt for the best quality solar charge controller, then they should choose a solar charge controller from the house of Enertech UPS Pvt. Ltd. They are one of the leading servo stabilizer manufacturers in India.
They have been associated with the fabrication and research of products falling under the category of solar power engineering for the past 25 years. They are pioneers when it comes to offering efficient and active solar energy solutions.
