Product Description

Product Description

Rooftop type resident photovoltaic system has been widely used in China, the Australia, United States, Europe and Japan. However,Due to the loose contact of photovoltaic module joint, poor contact, wire damp, insulation rupture and other reasons, it is easy to cause the phenomenon of DC arc drawing, resulting in fire.  In addition, when a fire accident occurs due to arc pulling or external reasons, as far as the DC side is concerned, as long as there is a light component, it will generate electricity. High voltage always exists. Fire fighting work is very dangerous, and firefighters can not rescue the scene, but can only control the fire from a distance.

FAQ

Q: If I'm interested in your DC Isolator when I can receive your quotation and detail information after send the enquiry?
A:All your enquiry will be replied in 24hours.

Q:Your DC Isolator seems perfect but what's the difference between you and other suppliers?Because I find some cheaper price from others!
A: Our DC Isolator is IP66 degree and they are high quality customized.for solar system I think compare the quality first and then compare the price is the best way.

Q:Can I get a sample before the order because I really don't how is your DC Isolator quality?
A:Of course!We also think sample order is the best way to build the trust.

 Q:How's the delivery?Because I really need them is urgently?
A:For sample order 3~7days will be no problem.And for regular order we promise in 15days.

Q:How's the warranty  period for your DC Isolator?
A:We offer 2-5 year warranty for our customer depend on different product

Q:How Can I chose correct model of Rapid shutdown Switches for my solar system?
A:For example:
The open-circuit voltage of each PV Panel is 39V, Aswich rapid shut down switches rated voltage is 1000V, so each route of MPPT max can connect PV panel quantity is 1000/39/1.15=22 pcs.
Such as your Solar Project has 162 pcs PV panel, so
162/22=8 sets of rapid shut down switches with 2 poles (ERS-2)
Or 162/22/2=4 sets of rapid shut down switches with 4 poles (ERS-4)
Or 162/22/4=2 sets of rapid shut down switches with 8 poles (ERS-8)
The Aswich rapid shutdown Current must be higher than the current of each string of your panels
