Buying Guide Of Best Off-grid solar inverter – Infographics
Just assume that you are searching the web looking for different solar inverters and don’t know which one to choose then you would waste many hours of your day just browsing meaninglessly as you can’t make a quick decision on which solar inverter is worthy of purchase.
In the contrast, if you’ve spent a few moments reading our buyer’s guide, you would be in a better position to make up your mind about which solar inverter to look for and you can very quickly decide on the ideal product for you.
In case you’re curious, about how the buying guide will help you in making this decision, just go through the given paragraphs and it’s enough to know the significance of a worthy guide directing your purchase. For this reason, pay careful attention, to the given review.
We are talking about the comprehensive review where you can read the detailed description of all of these things that will count in making any solar inverter the best one.
So, let us now dive into those features and look at, the worthy specs to make sure to buy one of the most popular and worthy solar inverters.
1. Things To Consider Before Buying The Off-Grid Solar Inverter:
Below given are the essential features and specs that you need to look at before heading for the final purchase of a solar inverter.
1. Type Of The Solar Inverter:
When planning to buy a solar inverter the very first thing that you need to mind is to look for the type of solar inverter that you want to have.
There are three general types of solar inverters available in the market. These three types are:
- On-grid Solar Inverter
- Off-grid Solar Inverter
- Hybrid Solar Inverter
The type of solar inverter will determine the purpose for which you are going out for the purchase.
If you are looking for a home standby power backup source and have a power bank to help you with that then a grid-tied on-grid Solar Inverter will be the best option for you.
This is because grid-tied solar inverters can work with the AC source of your grid supply line and give you utility power when the grid power is not available for instance during power outages.
These grid-tied inverters are home standby options that automatically power on and shift the load from the grid supply to the generator supply line.
This automatic conversion between grid power and generator supply is done by using a universal transfer switch that mediates this shifting.
But if you are a frequent traveler who is constantly out on the roads the utility power supply from your local grid is not the ideal option for you.
This is because you would frequently have to move to places where grid supply is not accessible.
Therefore, having a primary power source that is portable and can be transferred wherever and whenever you need it is the best bet to be your traveling buddy.
Many off-grid solar inverters are available at cost-effective price tags to offer you a grid-like experience while being away from your home.
These solar inverters work with the solar panels and power banks to capture the solar rays and convert them into a DC power supply which is then converted into alternating current by the inverter.
This AC power supply is also different for different solar inverters and the better inverter will give you a nearly grid-like experience that is suitable for sensitive electric appliances.
The third type is solar inverter is the hybrid series that combines the grid-tied function with off-grid use and thus gives you a highly versatile and multifunctional solar inverter that can be used anywhere and anytime including in your home.
The hybrid solar inverters are a higher priced and a better option as you don’t have to buy two devices for two different applications but rather a single multifunctional unit that will give you the best of both worlds.
But the higher price is not affordable for all customers and therefore, many buyers tend to buy off-grid and grid-tied solar inverters separately for the required job.
If you are restricted by your budget then an off-grid solar inverter will be the solution for your traveling needs and an on-grid Solar Inverter for the home standby power backup.
2. Capacity Of The Solar Inverter:
After deciding on the type of solar inverter the most significant thing for you to ponder over is to think about the capacity of your upcoming solar inverter.
There are different types of solar power stations and to complement those power banks inverters of the same capacity are needed.
So, if you are using a 3kw solar power station then a 3 kW solar inverter will be needed to work efficiently. You can also use the higher-capacity inverters but not the lower-capacity ones.
For instance, many people tend to buy a single heavy-duty 12kw solar inverter that they use with all of their solar power banks under 12000 watts of surge power.
The higher the capacity of the solar inverter, the higher will be its price therefore, you should not be going with a high capacity inverter as you desire but rather an inverter within your budget that you can afford and that will give you a higher efficiency performance.
3. Sine Wave Technology:
As we have stated above that not all solar inverters are equal in their performance although the basic function to be performed by all is the same.
All solar inverters will convert the DC power to AC power supply but the quality of this alternating current output will be different for each solar inverter.
This is because different inverters have different technologies, particularly the sine wave technology.
There are three types of sine wave technologies that are widely used in solar inverters, power banks, panels, and power stations.
- The pure sine wave technology
- The modified sine wave technology
- The squared technology
The pure sine wave is the best of all and also the most frequently used one. Most solar inverters and power stations are featuring the power sine wave AC technology that gives highly stable, clean, and green power suitable for sensitive electric and electronic appliances that would otherwise be damaged by the generator or non-grid power supply.
The second technology for solar inverters is the modified sine wave technology which is also very abundant though second to its successor technology, the pure sine wave.
This AC output slightly modifies the squared output and makes it look like pure sine wave technology but is not fully similar to it and has many loopholes in its performance.
The modified sine wave is better than the other technologies in its output power and will not cause any serious damage to your electric appliances but is not the best available option for you.
Therefore, it is recommended to buy only those inverters that feature the pure sine wave technology but if you have some budget concerns, you can try the cheaper option which is the modified sine wave technology but it should not be a preferred choice for best results.
The third and the rarest type to be used these days is the squared waveform that is used in some very simple solar inverters available at the cheapest bucks.
They will get the job of converting DC to AC power but the output will not be suitable for sensitive electronics like microwaves, drill machines, smartphones, etc.
Therefore, the squared waveform solar inverters should be avoided and you should try to save some bucks and go for the modified sine wave solar inverter s also termed the quasi sine wave inverters.
4. Protections:
Another significant factor worthy of your consideration before buying the solar inverter is the type and number of protections coming along with it.
Solar inverters are meant to be safe and secure for use so that you can use them to run your electric appliances without any worries of damage or fault in their operations.
The most basic protection that your solar inverter should come up with is waterproofing as the solar inverter will be connected to your solar panels and have to be placed in sunlight in outdoor conditions, a waterproof body is a must-have feature for safe working.
After ensuring the waterproofing you should move toward the internal components and see what safety measures solar inverter manufacturers have to offer you.
You should look for the following types of protections that need to be present as the priority in the solar inverter.
- Overheat protection
- Overcharge protection
- Short circuit protection
- Over-voltage protection
- Under voltage protection
- Overload protection
These six protections are mandatory for any solar inverter and many great inverter units are featuring 8 or 12 protective layers to give the best bang for your buck.
But the higher number of safety features present in your device, the higher will be the weight of your price tag.
Therefore, it is safer to go with these basic protective features and have an affordable solar inverter that is the best bet for you at the moment.
FAQs (Frequently Asked Questions)
