If this is the first time that you’re buying an inverter then there are a few important questions that you need to ask a manufacturer before you decide on which manufacturer is the best fit for you and your needs? We’re going to list and answer some of these questions that should be asked of any inverter manufacturer that you contact so that you know if the manufacturer knows what they’re talking about and isn’t giving you a song and dance. You need to know that the parts that you’re looking for are going to work for you. These questions will help ensure that you’re getting the best parts and the best services.
1. What is the equipment grade that you specialize in?
There are 3 types of basic inverters. What you’re looking for is going to either be residential, commercial, or industrial. You should be choosing the manufacturer that specializes in making the types of inverters that you’re specifically looking for. If they specialize in all three? Fantastic.
2. Is the manufacturing process performed in-house?
Your best option is to cut out the manufacturers that outsource. Having the products made right there is a better way to ensure a more quality product. A manufacturer that outsources will, often times, be unable to be there to ensure quality control.
3. In addition to stock models, do you produce custom models?
It is not uncommon for your power inversion needs to suddenly change. So even if you don’t need a custom model now, it’s possible that you may need one in the future. If you choose a manufacturer that can produce custom models then you won’t have to look for one later should you have the need for one.
4. Are the inverters available with NEBS certifications?
A NEBS is a Network Equipment Building System level 3 certificate that comes with industrial inverters that may be operating under adverse conditions. It’s usually a great idea to know whether or not the manufacturer offers these certificates.
5. What is the warranty for the particular inverter that I need?
As you may be aware, each manufacturer may offer different warranties. The same can be said for the terms and conditions. It doesn’t matter what you’re buying; you’re going to want the item that comes with a great warranty. With the terms and conditions, you’re not going to want a million of them because at that point anything can invalidate the warranty. Understand what you’re being offered and what it is that you’re getting.
6. Is there an OEM maintenance plan option?
This is a plan that is a great option if you’re not going to be maintaining your inverters in-house. Usually, this particular plan is free for a small period of time and in many cases will tend to cost more than third-party maintenance plans. Once you’ve used the free portion of your plan you can choose whether or not it’s the best option for you.
