Isolated Transfer Switches are designed to automatically open and close the circuit between the two power sources, without interrupting the flow of electricity. This ensures that there is no sudden loss of power during the transfer process, which could damage sensitive equipment or cause safety hazards.
What is Solar Energy Isolated Transfer Switch?
The Different Types of Solar Energy Isolated Transfer Switch
Is the difference between Isolated Transfer Switch and dual power transfer switch universal?
Solar energy Isolated Transfer Switch is a device used to safely and efficiently connect and disconnect a solar photovoltaic (PV) system to the main electrical grid. The transfer switch is an essential component of any grid-tied PV system, as it ensures that the PV system is disconnected from the grid during a power outage, preventing dangerous backfeeding of electricity.
There are three main types of solar energy Isolated Transfer Switch: string, central, and microinverter.
String Isolated Transfer Switch: A string type ITC is typically used in a residential PV system. It is the most common type of ITC and is less expensive than the other two types. A string ITC has one DC input and one or more AC outputs. The DC input is connected to the PV array, and the AC outputs are connected to the inverter(s) and/or loads.
Central Isolated Transfer Switch: A central type ITC is typically used in a commercial or utility-scale PV system. It is more expensive than a string ITC but offers several advantages, including higher reliability and lower maintenance costs. A central ITC has multiple DC inputs and multiple AC outputs. The DC inputs are connected to the PV array, and the AC outputs are connected to the inverter(s) and/or loads.
Microinverter Isolated Transfer Switch: A microinverter ITC is similar to a string ITC but with one important difference – each solar panel has its own microinverter, which means that each panel can operate independently from the others. This can be advantageous in certain situations, such as when shading occurs on part of the array (the unshaded panels will continue to produce electricity). Microinverter ITCs are more expensive than other types of ITCs but offer greater
Not universal. The Isolated Transfer Switch is unipolar. Generally speaking, for three-phase electricity, it has three inputs and three outputs, and there are a total of six wiring piles. For single-phase electricity, there are 2 in and 2 out, a total of 4 wiring pile heads.
The transfer switch is bipolar. Generally speaking, for three-phase electricity, there are 6 inputs and 3 outputs, with a total of nine wiring piles. For single-phase electricity, there are 4 in and 2 out, a total of 6 wiring pile heads.
