Technical FAQs 4

What is a solar isolation transformer?

The isolation transformer protects your household appliances, precision instruments (medical or industrial grade), energy storage systems (batteries), and other electrical equipment. It is usually installed inside the inverter product in the entire solar system.

Do I need an isolation transformer for my solar system?

If there are frequent power outages (there are only 4-6 hours of mains power supply a day), it is very necessary to add an isolation transformer to your solar system. An isolation transformer is completely electrically isolated between the input end (mains – charging battery) and the output end (electrical equipment – load).

What is a solar inverter?

Solar inverter is a kind of equipment that converts direct current generated by solar panels into alternating current, which is an important part of photovoltaic system.

Why do you need an isolation transformer?

Improve the adaptability of the power grid: When the voltage fluctuation of the power grid is large or there is a large motor, welding machine and other loads, the isolation transformer can prevent the current mutation and improve the stability of the system.
