Why Do You Need a Solar Inverter For Your Off-Grid System?
To answer this question, you have to understand the working mechanism of an off-grid solar energy system. Basically, an off-grid solar system is different from a grid-tied system. An off-grid system is not connected to any utilities and lets you become self-sufficient regarding electricity consumption.
In this type of solar system, you connect your solar panel to an inverter, then to one of several battery back-ups and finally to your electrical devices. Thus, if you have a surplus amount of energy then you can save it in your battery and use it during emergencies.
During this process, what your inverter does is that they convert the Direct Current (DC) version of generated power to Alternative Current (AC). Almost every electrical item you use on a day-to-day basis needs an AC version of electricity to operate. Thus it is crucial for you to convert your solar-generated current to AC version before use.
Moreover, solar inverters protect your system from ground faults and other threats. Most of the inverters also display stats regarding system performance. This will help you detect problems regarding any one of your solar panels or any other connection errors.
It also improves your solar system’s efficiency by minimizing power loss and providing more power to your battery.
Difference Between Pure Sine Wave and Modified Sine Wave Inverters
All the solar inverters that we have mentioned in this article are classified into two categories. The first one is a pure sine wave type and another is a modified sine wave type of inverter. We have provided a detailed description and difference between each of these inverters in this section.
Pure Sine Wave Inverter
If you are planning to power some of the most sensitive electrical appliances then you should consider this inverter. The pure sine wave inverters are more sophisticated than the other one and provide smooth arching waves as compared to the modified sine wave inverters.
You can power television, laptops, microwaves, digital printers, and all other types of home appliances with this inverter type. It prevents the device from getting damaged due to any kind of system failure. However, they are much more expensive than the other one.
Modified Sine Wave Inverter
This type of solar inverter is much more cost-effective than the pure sine wave inverters. But they do not produce enough power to operate sophisticated devices. They can power some of the simple devices such as charging your cell phone, some older version of televisions, heaters, etc.
In contrast to the pure sine wave inverters, they do not produce smooth arching waves. Therefore, you should consider this type of inverter only if you are planning to power some of the simple devices such as vacuum cleaners, water pump, etc.
Things to Consider Before Purchasing a Solar Inverter For Your Off-Grid System - Buyers’ guide
A solar inverter is a huge investment and thus you should not purchase a random product based on little knowledge. You have to conduct adequate research before selecting a perfect item for your needs. Therefore, we have described some of the important factors to consider before purchasing an off-grid solar inverter.
Power Efficiency
The function of the solar inverter is to convert the DC power obtained from the solar panels to its connected batteries. However, it cannot convert a perfect 100% of obtained DC power to the AC version. Some of the energy is wasted during the conversion process.
You have to look at the conversion rate of a solar inverter before making your purchase decision. If its conversion rate is 96% than 4% of the total DC power is being wasted. You should search for inverters with the conversion rate of at least 94%.
Power Consumption
Your solar inverter will consume a certain amount of power during operation. You have to know how much power is consumed during its operation. Also, when your inverter is not in operation, how much power is it consuming during the ideal stage? This information will make it easy to determine which product works best for you.
Inverter Type
As we have mentioned above, there are two distinct types of solar inverters. One is the pure sine wave and the other is a modified sine wave inverter. You have to determine which type of inverter works best for your devices based on their difference. If you are powering simple devices then a modified sine wave inverter works well.
However, if you have to power some sensitive devices such as your laptop or refrigerator then a pure sine wave inverter type is the one for you.
Technical and Customer Support
Solar inverters are sophisticated devices and you have to contact the technical team if something goes wrong. Therefore, if the manufacturer of your solar inverter provides good technical and customer support then you won’t feel a burden to take care of your device on your own.
Warranty Period
Your inverter’s manufacturer should provide at least one year of warranty for the product. Some of them provide as much as 20 years of warranty whereas others might provide from 1 to 10 years of the same. However, if an inverter has no warranty backed up by their manufacturer then you might face trouble later on.
Since solar inverters are sophisticated appliances, you should not try to fix any internal issues related to it. Therefore a long warranty period is crucial for such appliances.
Frequently Asked Questions (FAQ)
The solar inverter is an essential component of a solar energy system that converts the DC version of electricity into AC. Initially, it receives the Direct Current (DC) from one or more photovoltaic (PV) solar panels connected to the system. The DC electricity flows monotonously in a one-way direction, and this type of electricity cannot power common US household appliances.
Therefore, it has to convert the one-way current into an Alternating Current (AC) that periodically reverses its direction, making it perfect for such appliances.
Based on the quality of your solar inverter and the number of solar panels connected to the device, it may produce some humming noise during operation. However, at night time when the inverter is not in use, it will not produce any noise.
Some of the solar inverters turn themselves off when the PV panels are not working. Thus freeing you from manually turning it off after the sunset. They turn on immediately in the morning when the panels receive sunlight and send DC power to this device.
Yes. All solar inverters’ performance is dependent on the ambient temperature. Each inverter has a certain range of temperature within which it gives higher efficiency. Thus, you have to know the temperature range of a particular off-grid solar inverter before purchasing.
