Evaluating Inverter Manufacturers: Questions to Ask Before You Make a Purchase

The performance and lifespan of a frequency inverter are largely attributable to the company that manufacturers it. However, with hundreds of inverter manufacturers flooding the market with their similar products, knowing which company to buy an inverter from can be difficult, especially if you aren’t an electrical engineer who knows exactly what you’re looking for. If you need to evaluate inverter manufacturers, asking the questions below is a good way to start.

Does the company specialize in manufacturing inverters?

Ideally, you should buy an inverter from a company that specializes in manufacturing the product. The more a manufacturer stakes its revenue and reputation on a product, the more reason it has invest in making the product an excellent one. Instead of buying an inverter from a company that sells a wide selection of electrical infrastructure equipment, buy it from a company whose core competency is designing and producing high-quality frequency inverters.

Does the company produce the grade of inverter you need?

Inverters are made for different grades of use. If you need an inverter for a residential application, don’t overpay for an inverter that’s designed for industrial applications. By the same token, using a residential grade inverter for industrial applications will likely cause the device to fail during service, if it works at all. Before you start shopping, identify the grade of inverter you need in terms of its construction, and the load size and load characteristics of your building.

Does an inverter have the necessary certifications?

If you need an inverter that operates under adverse conditions, you probably need a product that has Network Equipment-Building System (NEBS) Level 3 Certification. If your company has a green initiative, you may also need a product that has a Restriction of Hazardous Substances (RoHS) certificate. Before you buy an inverter, find out about the certifications it possesses and whether your company needs them in terms of inverter performance and policy compliance.

Does the company have a good business reputation?

Before you buy an inverter, be sure to assess the reputation of the seller. Does its record at the Better Business Bureau (BBB) have unresolved customer complaints? Do former customers give conflicting reports about the quality of its products and customer service? If so, you should probably choose a different seller. In particular, look for inverter manufacturers that provide strong post-sale technical support, as you may need advice on implementing the product.
