Understanding inverters - how to choose the right backup solution to power your home
In the last article, we learnt about solar installations and the foundations of energy solutions. In this piece, we will go a bit further and while it can get a bit technical, we will explore the different types of backup inverter solutions that can potentially power your home.
It's the news everywhere: South Africa is currently grappling with a power crisis that has left many homeowners searching for reliable alternatives to keep their lights on and their appliances running. Inverters, a vital component of backup power systems, offer a promising solution by converting energy stored in batteries or produced by solar panels into usable electricity.
Understanding inverters
Inverters come in various shapes and sizes, but their primary function remains the same: to convert direct current (DC) electricity into alternating current (AC) electricity that can power your home. They act as the heart of a backup power system, ensuring a steady and reliable energy supply.
There are many different types of inverters on the market, and it can be difficult to know which one is right for you. Here are a few things to consider when choosing an inverter:
- The size of your system: Your power consumption will determine the size of the inverter you need. A larger home with larger energy needs will require a larger inverter.
- The type of appliances you want to power: Some inverters are designed to power higher energy consuming appliances, such as kettles, refrigerators, air conditioners. If you want to power a variety of appliances, you will need an inverter that is designed to handle the load.
- The cost: It's important to choose an inverter that fits your budget.
- Your energy source: Will you be using energy stored in batteries, energy from the grid, or energy generated by solar panels.
Grid-tied inverters
Grid-tied inverters allow energy to flow from their solar or grid source into a home. However, they usually don't support the connection, charging, and the using of backup rechargeable batteries.
These inverters rely on the grid as their main source of power, which means they are unable to provide electricity when the grid goes down. As a result, they are not suitable for use during power outages or load shedding situations.
The primary purpose of these systems is to reduce reliance on the grid by directly using solar power for immediate consumption, without the need for battery storage.
Bi-directional inverters
A bi-directional inverter converts DC from a battery or solar source into AC for household use. It can also convert AC from the grid back into DC to recharge batteries.
The battery can be charged from different sources, including the grid, solar panels, or even a generator.
The bi-directional inverter effectively handles the power supply from different sources and ensures that the required power is provided without causing any harm to the batteries.
Hybrid inverters
A hybrid inverter establishes direct connections to a battery, a solar array, the grid, and the household DV board. Thanks to its integrated design, hybrid inverters efficiently and intelligently manage both solar power and backup electricity supply for households, on one solution.
When hybrid inverters are linked to household loads, they divide the power between essential loads (such as lights and plugs) and non-essential loads (such as the geyser or pool).
In the presence of solar power, the inverter prioritises supplying this energy to essential loads. If the solar panels generate an excess of power beyond the immediate requirements, the inverter begins charging the battery. Once the battery reaches full capacity, it can then direct the surplus energy towards non-essential devices and appliances.
Mobile inverters
Mobile inverters are compact and portable devices that convert DC power from a mobile power source, such as a car battery, lithium battery or a portable generator, into AC power that can be used to operate various electronic devices and appliances. These inverters are designed for on-the-go use and are commonly used in vehicles, camping trips, outdoor activities, or any situation where AC power is needed away from traditional electrical outlets.
Mobile inverters typically come with multiple AC outlets and sometimes include USB ports for charging smaller devices like smartphones or tablets. They often have built-in safety features such as overload protection, short-circuit protection, and over-temperature protection to ensure safe and reliable operation.
