Solar Panel Dc Isolator

The solar safety shutoff is different in that it tackles the problem of dc isolation at the source i e.
Solar panel dc isolator. Pgk solar dc isolators the best in australia. This dc isolation switch must be used for all pv circuits. Solar isolators for photovoltaic. Cobaltblack dc has a robust uv stabilized aluminium polycarbonate enclosure and is recommended for all quality solar installations and repairs.
4 pole d c isolator asm xa100 16d4h h. Safe reliable and used by hundreds of companies australia wide. Independent third party testing to ensure the highest quality product. The second disconnect is the ac disconnect.
Suitable for pv installations. Without these type of switches there is a real time risk of electrical shock. Photovoltaic installations have to be equipped with dc isolators according to iec 60364 7 712 iec 60947. 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.
The ac disconnect is used to separate the inverter from the electrical grid. Before the panels combine to lethal d c voltages. The pv disconnect allows the dc current between the modules source to be interrupted before reaching the inverter. 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.
The first is the pv disconnect or array dc disconnect. Dc isolators should be selected according to the maximum voltage and current of the panel string. 3 rated current voltage of string of panels. 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.
Research found most were too flimsy not suitable for on roof. Solar isolators si are switch gears for interupting the dc ac inverter from the solar panels. 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. A solar pv system typically has two safety disconnects.
Dc pv isolating switches are necessary to turn the power off pv systems under load.
