A Quick Guide to Buy Solar Inverter & What to Compare While Selecting One

    Whether you are looking for upgrading an existing solar system or buy a new system; the inverter is an essential device which turns power from panels into electricity for a home. The solar inverter is one of the complicated parts & also the first part to get failed, mostly. They are categories in 3: string, microinverters and hybrid. Each has its own merits and demerits. So, again the question would arise; which one is suitable for my solar system? To get the answer; read on.

    Let’s start this with a simple example or you can say an assumption.

    You have got quotes or price estimates from many solar panel systems and you have heard the same thing every time “we sell the quality solar inverters at an affordable rate”.

    Is it possible? No, not at all.

    In this buying guide, you can get quick information about solar invertors that help you get the right solar inverters.

    Before moving ahead, let me clear that an inverter is a critical and essential part of your system and without it; you can’t transform sun heat into usable electricity.

    Types of Solar Inverters:

    String Inverters: This is one of the most common inverters for residential use. You need to connect the strings of panels to them to get the usable electricity.

    Microinverters: These are tiny solar inverters, the size of a paperback book. You should have at least one per panel.

    Central Inverters: With a large capacity of hundreds of kilowatts, central inverters look similar to a big cabinet. These are widely used for commercial purpose, not for residential use.

    Hybrid: A name itself suggests a multi-mode inverter that allows you to plug multiple batteries into your system. It uses a DC coupling technique to generate power.

    Among the 4 types; you can choose as per your requirements. All have their uses and applications.

    Solar Inverter Price:

    To buy anything; you need to pay and that’s the universal fact. But whatever you pay for something; it must be worth. The same rule is applied here too.

    The cost of an inverter varies from ~$900 – $2,500, depending on the types, size, quality and efficiency of a solar inverter. Moreover, the cost of installation may be in between $200 to $300 additional. You can get some refund replacing the inverter. But it’s more important to buy a quality one that will last long.

    Once you decided your budget and brand; you should consider the following things while buying a new solar inverter. This will help you get a perfect one & won’t disappoint you.

    The Size of an Inverter:

    To understand it quickly, let’s see an example. If you have a kW system, you must have 8kW inverter to get the maximum output through your solar system. Quite simple, right? Some installation companies advise buying an undersized inverter because of solar degradation. If you wish to add more panels in your solar system in the future, you need to buy a larger inverter.

    Inverter Warranty:

    The manufacturing companies provide a standard warranty of 5 to 10 years. While some major brands offer you a warranty on the installation workmanship. Of course, you can pay extra for the extended warranty too.

    Solar Inverter Efficiency:

    The solar inverter efficiency is crucial for the performance of your solar system. Yes, it’s true. You can neglect solar panel efficiency while buying it but not here. You need to consider this first, instead. The higher the efficiency, the more power it will generate and so, the more money you can save.

    Remember, the power your solar system produces is depended on the efficiency f your inverter. Do I need to explain “why you should invest in quality inverter”? Different brands offer different inverters with varied efficiency. You can compare them based on efficiency.

    The efficiency measures on how much power an inverter converts from DC to AC. A 92% efficient solar inverter is good; only 8% of power would waste and that’s not a big deal. Some giant brands offer inverters with 96% to 98%, however, they sell at the highest price but it is worth to have one.

    A well-functioned and long-lasting solar inverter can save you thousands of bucks. It’s a kind of one-time investment. If you compare and consider the above factors before buying; there is a chance you may end with a wrong one.

    Follow the above guidelines, get the right solar inverter for your home system and reduce your electricity bill.
