How much short circuit current (Isc) do you actually get? It's easy measurment by multimeter, 10A range and put proves to panel's + &amp; -.

I checked the Isc when I first bought the panel and I don't remember the exact number but it exceeded the number that was printed on the label on the back of the panel.

I have five 100 watt panels now, wired together with MC4 split connectors and running 25 feet to my charge controller. My panels have a working voltage of 18.5V. That gives me 5.5 amp per panel in direct sun. In total I get 27 - 28 amps on a clear day. I have no problem with voltage drop but I am now max'd out on my 30 amp charge controller and the 10 guage wire. If you have a larger system than that you will need heavier wire, unless your panels operate at a higher voltage, wich would lower your amps. As long as you are under 30 amp this wire works great. I hope this helps.Dan

I have had this unit for almost a year now! Works flawless with my two 250 watt Kyrocera panels, ( mono crystalline ) 12volt. Hope this helps u

Cut off the MC4 connectors... strip the insulation, and connect the wires with appropriate connector. How many watts is the panel?

I used it as a DC test not AC. I tested it with an Oscope and found it peaked the circuit so it would work for what I bought it for. I was afraid of burning up the iunits next to what I was testing so I have very little time with it.

I have 2 units and have to issues with neither of them...I use it for basic AC and DC power reading takes. I do get some insignificant reading when power on but when connecting to the power source for measurement works well and power reading are correct.I hope this helps....

most cases no it does not. as long as your panels do not exeed the range listed on the input(if you cannot use or understand a multimeter do not purchase product) although the product i purchased did not work and had to fight tooth and nail after sending faulty product back for 4 months to get my money back. If it sounds to good to be true it probably is!!

There is no multimeter that isn't sensitive enough to determine this. However it is usually 24VAC, at least in the US but custom bundled transformer and bell sets may differ.

I have SIX panels and I can't break 30 amps. The ratings are PERFECT, not reality. Line losses, connection losses, etc all drop the actual down. Just wire with the maximum thickness copper wiring you can.

31.666 amps is where you are with your 4 panels. I agree with AT... You need a larger charge controller or research using multiple controllers.

Those are the old current ratings. Now, it is 120/240, and this is a 120 volt product (normal household current). It does call for its own 20 amp breaker protected circuit, but I did not install one. I ran it on the same circuit which has handled two bathrooms and their exhaust fans for 50+ years. I have had no problem with tripped breakers when using my heater function, exhaust function, light and other lights on that circuit simultaneously. If you go that route but start tripping the breaker on the circuit, you will have to run a new line with a dedicated breaker.

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

I concur with the other 7 answers you've received so far. The only worry might be the extra 10 amps, 25% more than what the original installer decided on. My breaker hasn't blown but hasn't had a reason to do so.

Trying to draw 100% of the rated load of a power supply is not a good idea. Especially with these cheap power supplies, I wouldn't go over 80%. According to Joseph's measurements, the terminals are off the same bus so depending on the design, shorting them wouldn't help anyway.

Glen 59: did you use an inline ammeter to measure the actual current passing through the cable? Or are you just saying you are pleased at how fasr these power banks charged?

I'm not 100% because we were triggering something very low current. I want to say it was somewhere in the 10-15a range?

This is not a good option, I'm sorry. I suggest looking for a 10watt 12v panel that discloses the actual specifications of the unit. The output voltage is undisclosed and I had very irregular performance.Hope this helps...good luck.
