1. What grade of equipment do you specialize in manufacturing?

In terms of construction grade, there are three basic types of inverters: industrial, commercial, and residential. Choose an inverter manufacturer that specializes in producing inverters that have the construction grade you need.

2. Do you perform the manufacturing process in house?

It&#;s typically a good idea to buy inverters from a manufacturer that handles the production process in-house, as opposed to outsourcing it to a third party. A manufacturer that works in-house has greater quality control over manufacturing.

3. Do you produce custom models in addition to stock models?

You may not need a custom inverter now. However, it isn&#;t uncommon for power inversion needs to change, and require the implementation of custom equipment Having a business relationship with a custom inverter producer removes the need to look for one in the future.

4. Are your inverters available with NEBS certifications?

If you need an industrial inverter that can operate under adverse conditions, you may require a model that comes with a Network Equipment-Building System (NEBS) Level 3 certificate. If you need an inverter that offers the reliability of NEBS Level 3, be sure the certificate is available.

5. What is the warranty for the inverter I need?

Not every inverter manufacturer offers the same warranty terms and conditions. Naturally, you want the longest warranty possible. However, you also want a warranty that has as few terms and conditions that could prematurely invalidate the warranty period.

6. Do you provide OEM maintenance plan options?

If you won&#;t maintain your inverters in-house, receiving an original equipment manufacturer maintenance plan can be quite helpful. The plan is often free for a short period of time, and then tends to cost more than independent, third party maintenance plans. After using the plan for free, you can decide whether paying for it is a good option.

UL (Underwriters Laboratories) Certification: It is widely recognized in North America and is an essential certification for products entering the US market. UL is the specific standard for inverters and converters used in renewable energy systems.

IEC (International Electrotechnical Commission) Standards: Particularly IEC -1 & IEC -2 which are safety standards concerning the photovoltaic inverter&#;s design and operation.

CE Marking: This is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) and indicates compliance with EU standards.

VDE (Verband der Elektrotechnik): It is a German standard which is highly regarded in Europe. VDE-AR-N is a specific standard for connecting an inverter to the power grid in Germany.

CQC (China Quality Certification): It is essential if you are importing inverters from or selling in China. This certifies that the products meet Chinese safety and quality standards.

SAA (Standards Association of Australia):This is an important certification for products entering the Australian market, and it indicates that the inverters have been tested and comply with the Australian standards.

TUV (Technischer Überwachungsverein): It&#;s a globally recognized certification indicating safety and sustainability. TUV testing ensures that inverters meet defined criteria and standards.

RoHS (Restriction of Hazardous Substances): This certification is crucial in the EU and ensures that the manufacturing of products, including inverters, is environmentally friendly and restricts the use of specific hazardous materials.

FCC (Federal Communications Commission): This certification is important in the United States, ensuring that the electromagnetic interference from the inverter is under the limits approved by the federal government.
