Understanding Inverters
For a deeper dive on inverters check out our previous article: How to Size your Solar System Inverter. But for the purposes of this article, we’ll give you the highlights.
Inverters play a vital role in off-grid solar systems by converting direct current (DC) power generated from solar panels or stored in batteries into alternating current (AC) power, which is the standard form of electricity used in households and most electrical appliances. This conversion enables off-grid users to power their homes, cabins, vans or other dwellings with solar energy, even when they are disconnected from the traditional power grid.
Explanation of the Difference between Pure Sine Wave and Modified Sine Wave Inverters:
When it comes to choosing an inverter for your off-grid solar system, understanding the difference between pure sine wave and modified sine wave inverters is crucial.
Pure Sine Wave Inverters: Pure sine wave inverters produce an electrical output that replicates the smooth, undulating waveform of utility-grade AC power (see figure below). They deliver a clean and consistent flow of electricity, similar to what you would receive from a standard power outlet in your home. Pure sine wave inverters are designed to power a wide range of devices, including sensitive electronics such as laptops, televisions, medical equipment, and other appliances that require high-quality AC power. They are highly efficient and provide reliable performance, making them the preferred choice for most off-grid applications.
Modified Sine Wave Inverters: Modified sine wave inverters, on the other hand, generate an approximation of the AC waveform using a stepped waveform. The output of a modified sine wave inverter consists of a series of square waveforms, which are not as smooth and consistent as the pure sine wave (see figure below). While modified sine wave inverters are generally more affordable, they may not be suitable for certain types of devices. Some appliances, particularly those with sensitive electronics or motors, may experience reduced performance or produce audible buzzing or heating issues when operated with a modified sine wave inverter.
It is important to note that the choice between pure sine wave and modified sine wave inverters depends on the specific requirements of your off-grid system and the devices you intend to power. If you have sensitive electronics or appliances that require high-quality AC power, a pure sine wave inverter is recommended to ensure optimal performance and longevity of your equipment. In fact, there aren’t many situations I would really recommend a modified sine wave inverter. For that reason, we only offer pure sine wave inverters on our DIY Marketplace.
What Size Inverter do I Need?!
I would again point you to our previous article for a deeper dive on this: How to Size your Solar System Inverter, but once again, we’ll boil it down for you and try to make this simple.
Choosing the right size inverter for your off-grid solar system is crucial to ensure efficient and reliable power generation. Here are some key factors to consider when determining the appropriate size of the inverter:
- Load Calculations: Start by assessing the power requirements of the appliances and devices you intend to power with the inverter. Make a comprehensive list of all the loads you expect to operate simultaneously. Note down their power ratings in watts or kilowatts. Consider both the continuous power required to run the devices and any additional surge power needed during startup. This will give you an estimate of the total power (wattage) your inverter should be capable of handling. This is a critical exercise for inverter sizing. Think of the inverter as the component in your system that determines how much power you can use at one time. If you only need to power small electronics, such as TVs and tablets, a small 700 to 1000 Watt inverter will do. But if you want to cook or power your heating and cooling needs, a much larger inverter would be in order.
- Surge Power Requirements: Many appliances, especially those with motors or compressors, require an initial surge of power when they start up. Think refrigerators, air conditioners, large power tools, etc. This surge power can be several times higher than the appliance’s continuous power rating. Take into account these surge power requirements when selecting an inverter. Ensure that the inverter you choose can handle the peak power demands of your appliances during startup to avoid potential overload or inverter failure. When you look at an inverter power rating you will see two values, a lower value which tells you how much power it can continuously handle; and this higher rating, or surge power capacity, which tells you how much increased power the inverter can handle for short durations.
- Future Expansion Considerations: Consider your future power needs and any plans for system expansion. If you anticipate adding more appliances or expanding your off-grid system in the future, it’s advisable to choose an inverter with a higher power rating than your current requirements. This will provide flexibility and allow room for future growth without the need to replace the inverter. Considering the cost of inverters and the relatively low cost of upsizing, it often makes sense to give yourself extra “room” when it comes to selecting an inverter.
- Inverter Efficiency: Take into account the efficiency of the inverter. Inverters have varying efficiency levels, with some models being more efficient than others. Higher efficiency means more of the power you are generating is used for it’s intended purpose. Look for inverters with high efficiency ratings to maximize the utilization of your solar power.
- Safety Margins: It is recommended to incorporate safety margins when sizing your inverter. This involves selecting an inverter with a power rating slightly higher than your estimated load requirements. By providing a buffer, safety margins account for unforeseen power spikes or future additions to your load. It helps ensure that your inverter operates within its optimal range and avoids running near its maximum capacity, which can reduce its efficiency and longevity. I’ve frequently heard from folks wondering why their system keeps tripping off. Often, an undersized inverter can be the culprit.
By carefully considering load calculations, surge power requirements, future expansion plans, efficiency, and safety margins, you can determine the appropriate size of the inverter for your off-grid solar system. This ensures that your system operates smoothly, providing reliable and efficient power to meet your energy needs.
