In a blog post from Sona Solar Zimbabwe, find out how an best Off-grid Solar Inverter was created, what it is able to provide, and the benefits that it provides for people.

What is an Off Grid Solar Inverter?

When it comes to solar power, there are a few different types of inverters that can be used. The most common inverters are those that use DC Power to convert the incoming solar energy into usable AC voltage and current. These inverters come in two main types:

1. Grid-connected and 
2. Off-grid Inverters.

Grid-Connected inverters are designed to work with the electrical grid. They receive their power from the grid and then use that electricity to turn the sun’s energy into usable AC volts and current. This type of inverter is usually more expensive than an off-grid inverter, but it’s also more reliable because it uses established infrastructure. Off-grid inverters, on the other hand, don’t rely on any external power sources. 

They are designed for use in isolated or remote areas where access to clean electricity is uncertain or nonexistent.

How to Pick the Best Off-Grid Inverter:

Think About Size: 

The first thing to think about is how much power you need. Fortunately, sizing off-grid inverters is straightforward if you know what appliances you’re going to use. Add up the wattage of all your lights and appliances to calculate the number of watts you’d need if everything was used all at once. (No, you’re not likely going to use everything, but this is an easy way to be safe.) Don’t forget to consider the voltage—although most appliances run on 120Vac, some appliances, such as well pumps, require 240Vac. 

Example: Let’s say you need 1,000 watts for your fridge, 500 watts for lights, and 200 watts for your phone & TV. That adds up to 1,700 watts. In this case, we would suggest a minimum inverter size of at least 2,000 watts to give you a little extra headroom. (After all, you may add appliances in the future.)

What Is The Most Popular Size We Sell At Sona Solar Zimbabwe? The 3kVA followed by 5kVA. Different models and brands are available in various sizes and most of them can be stacked together for higher power output.

Consider Pure Sine Wave Instead of Modified Sine Wave:

You may hear some manufacturers talk about pure sine wave inverters. You don’t need to understand exactly how these work—it’s enough to know that the power that’s put out by a pure sine wave inverter is “cleaner” than what you’d get from a modified sine wave inverter.

Pure sine wave inverters deliver higher quality power output, similar to (or better than) our power grid. Modified sine wave inverters are cheaper, but they deliver lower-quality power output.

For this reason, modified sine wave inverters can cause issues with certain appliances. Motors, pumps and compressors run hotter and wear out more quickly. Certain sensitive appliances like computers can be damaged, or they may not work at all. These inverters also typically cause background noise on a stereo, and reduced video and audio quality for certain TVs.

That’s why we don’t recommend modified sine wave inverters for most applications; most of our off-grid customers are use pure sine wave inverters to avoid these potential issues.

Look at the Technical Specs

Here are some other technical specs to consider:

1. Efficiency. This is a measure of how much power from the batteries your inverter delivers to your home when it’s operating in perfect conditions. A good peak efficiency rating is around 94% to 96%.
2. Self-consumption, or no-load current draw. How much power will your inverter consume just sitting there? Obviously you want this to be as low as possible.
3. Surge capacity. How much short-term overload can the inverter handle before it “trips?” Some appliances, like pumps or fridges, need as much as 2x–3x their running power to start up.
4. Battery charger output. Many off-grid inverters include a battery charger, which is used to recharge your batteries during the winter months with a backup generator. The battery charger will have a rating, usually measured in amps. Most decent off-grid inverters will have a battery charger in the range of 50-100 amps DC.
5. Temperature range. Inverters are sensitive to extreme heat. Pay careful attention to the temperature range if you plan on installing your system in your garage or anywhere it could be exposed to temperature extremes.
6. Warranty. Warranties start at 1 year and typically range from 3-5 years, with a few manufacturers offering a 10 year warranty extension option.

You can normally find information on all these features on the product spec sheets. Check with your solar tech for help comparing and picking the right inverter.

Research Features

Your Inverter may need special features. Look into these ones:

1. Battery charger. A charger allows your system to be charged from a backup AC generator. Most bigger inverters include this; these are called “inverter/chargers.”
2. Grid-tied capability. Some off-grid inverters have the added capability of feeding power into the grid.  This capability is useful if the grid becomes available in the future, or if you are setting up a grid-tied system with battery backup.
3. Automatic generator start. Usually you will need an add-on accessory for this, although some inverters or charge controllers can take care of it.

Read Up on the Manufacturer

Knowing about the inverter manufacturer is also important. Check into their history and reputation. Off-grid inverters need to be on all day, 365 days a year, for several years at a time—so you’ll want to choose one from a manufacturer with a reputation for reliability.

In our experience, there are only a handful of companies making high quality inverters for this purpose:

Don’t Forget Price!

You also need to look at the price of the inverter system (including all required components)—as well as the features you get for that price. Make sure to compare the price of all required components, including the remote control, circuit breakers, mounting plate, and anything else required to install the system.
