Product DescriptionRooftop
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. Aswich

components, fast and convenient after-sale serviceFAQQ: 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
productQ: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 /* January 22, 2024
