Unveiling the Hidden Secrets of DC Isolators

The solar panel installation market is experiencing rapid growth, making the task of fitting DC isolators a common one for electricians. However, the wiring may be unfamiliar to many. Thankfully, Garo's DC isolators can be arranged in various ways to accommodate different voltage and current limits, enabling easy switching and isolation.

did i miss something? what's the hidden

Was expecting this to actually be more of an explanation of how dc isolators differ from ac. No real secrets shown just an install..

Glands are different ! I so wish manufacturers would loose the knockouts, nobody actually knocks they out as you always crack the wrong ring. It would give you many more options

Nice to see you guys using flathead screws to mount the unit! As they weaking the plastic which leads premature collaps...

Next time use dome head with a flat bottom.

My former boss learned that lesson the hard way mounting Brightwell soap and paper towel dispensers in high risk areas.

Craig & Derricott 16A 1000v Isolator with padlocking handle - I thought. After trying trying trying to slide the lock so as to padlock I read the instructions with no.4 saying PV switch handle padlocking has been disabled. Thanks for that. It still goes on and off for £12.03 dated 2015. I did mention DIY.

thats why they are burning... crimped soft cabel that fades under tension of the screw and start heating up... and mounted on flamable osb panel 😂... use a wago spring loaded type instead... or regulary tight the screws

[therealdojj]

all i heard was joe telling us about no such thing as a torque calibrated arm...

[Xoreaf]

Thought the advice was not to fit dc isolators anymore?

[electrogestapo]

The secrets remained secret apparently.

How do you size a solar disconnect switch ?

[jonipalosaari]

Switch that turns 0/I.
In another news.. Water, wet.

[AndrewMetcalfe]

Can anyone tell me, what hidden secrets were unveiled here?

[authuruksake]

Why feed the first set of wires from the top, down underneath, then into a pole that is switched with a link back to the outgoing wires, (next to the incoming wire (running down & up)) & exit underneath the switch.
Some may claim you are sharing the DC current across 2 switched poles - even though the switch is rated on all 4 poles inside...
But you could have run the top wires into 1 pole - with it's link to pole next to it, then the incoming wire is sharing the load across two poles - which exits on a wire sharing two poles to the inverter - leaving the lower links intact that was removed.
Finally ALWAYS TRIPLE CHECK DC switches POLARITY as some like Stag/IMO have the switches poles arranged diagonally & not straight down like you might assume to be common to all switches.

[thomasramsay]

Those stuffing glands seem overpowered

[deang]

4 terminals..
Is that a 3 phase + N isolator?😭😭😭

[jackdubberley]

In another video you say we shouldn’t use them solar but here your using them for solar. Confusing

[smoothoperator]

Whats the clip-ons in the last second of the vid?? That was the only interesting thing

[jamieharland]

Well, that was a complete waste of time !!

[hussainaslam]

The fact that he is working with dc wire and using black color cable for positive wire
