4 FAQs about Installation of inverter transformer for solar-powered communication cabinet

How do solar inverters work?

Inverters convert DC generated solar power into AC. They handle the wide swings in power supplied from the solar array. They also steady the voltage supplied to the step-up transformer. The inverters do all this with special switching that regulates their power output. This switching often creates power quality problems in the system.

Which part of a solar array connects to a step-up transformer?

Inverters are the part of the solar array that connects to the step-up transformer. Inverters convert DC generated solar power into AC. They handle the wide swings in power supplied from the solar array. They also steady the voltage supplied to the step-up transformer.

What voltage is used in a solar transformer?

You'll usually find 690V used with larger MW-scale solar sites or wind generation. 800V is usually used with European inverter manufacturers. Due to the remote nature of many renewable projects, solar transformers are often outfitted with alarm contacts on the gauges.

How do I connect multiple inverters to a PV system?

When there is only one inverter in the PV system, connect the additional grounding cable to a nearby grounding point. When there are multiple inverters in the PV system, connect grounding points of all inverters and the PV array frames to the equipotential cable (according to the onsite conditions) to implement an equipotential connection.
