Technical FAQs 4

What is a DC isolator switch?

In PV applications, DC isolator switches are used to manually disconnect the solar panels for maintenance, installation or repair purposes. In most solar PV installations, two DC isolator switches are connected to a single string. Normally, one switch is placed close to the PV array and the other close to the DC end of the inverter.

What is a true DC isolator?

Since its launch, the SI range of TRUE DC isolators has set the benchmark safety standard for disconnection and isolation of the DC panel load in solar applications world-wide.

What is a solar electrical DC isolation switch?

ETEK is committed to providing the best service for our customers! Solar Electrical DC Isolator Switch is an electrical safety device that manually disconnects itself from the modules in a solar PV system.

How does a DC isolator work?

In most solar PV installations, two DC isolator switches are connected to a single string. Normally, one switch is placed close to the PV array and the other close to the DC end of the inverter. This is to ensure that disconnection can be achieved at ground and roof level. DC isolators can come in polarized or non-polarized configurations.
