Solar Panel Dc Isolator

The pv disconnect allows the dc current between the modules source to be interrupted before reaching the inverter.

Solar panel dc isolator.

3 rated current voltage of string of panels. The solar safety shutoff is different in that it tackles the problem of dc isolation at the source i e. Cobaltblack dc has a robust uv stabilized aluminium polycarbonate enclosure and is recommended for all quality solar installations and repairs. Without these type of switches there is a real time risk of electrical shock.

The cobalt black dc isolator was first produced by us when it was apparent that the industry had a legitimate concern for the service life and safety of dc isolators. Solar isolators for photovoltaic. Photovoltaic installations have to be equipped with dc isolators according to iec 60364 7 712 iec 60947. The solar safety shutoff is capable of simultaneously isolating solar panels stopping the combining of panel voltages and limiting the system voltage to the safety of extra low voltage.

Solar isolators si are switch gears for interupting the dc ac inverter from the solar panels. Dc isolators should be selected according to the maximum voltage and current of the panel string. This dc isolation switch must be used for all pv circuits. Safe reliable and used by hundreds of companies australia wide.

The ac disconnect is used to separate the inverter from the electrical grid. Enzpower ip66 solar system solar combiner box 32a pv dc isolator switch with solar connector for solar power system rv boats and off on grid solar system 4 7 out of 5 stars 13 105 60 105. Before the panels combine to lethal d c voltages. The second disconnect is the ac disconnect.

It was intended as an additional safety mechanism as there are also isolator switches at ground level adjacent to the inverter or enclosed within the inverter itself. Roof top mounting bracket asm rtbrk 525. Research found most were too flimsy not suitable for on roof. 4 pole d c isolator asm xa100 16d4h h.

Dc pv isolating switches are necessary to turn the power off pv systems under load. Pgk solar dc isolators the best in australia. The first is the pv disconnect or array dc disconnect. For external dc isolators you can choose 4 pole 6 pole 8 pole for multi string solar panels or select 2 pole for one string of solar panel based on the different system design.

Pictured above a rooftop dc isolator is manually operated switch situated adjacent to a solar panel array that shuts off dc current between the array and the solar inverter.
