How much short circuit current (Isc) do you actually get? It's easy measurment by multimeter, 10A range and put proves to panel's + & -.
1662734
Highest I have measured, is 0.89A short circuit through a double-glazed window with the sun 30 degrees away from perpendicular to the panel.
1662735
I've had values ​​up to 1.35 A with on good sunny days. Normal values ​​of 0.8 to 1.1.It's easy to measure current Isc, as you point out, with the multimeter in 10A range, and placing the test leads to the cable ends of the panel, + and -. It is desirable that the multimeter has a resolution of 10 mA.

It's going to vary a bit on the day, and as I don't have a standards measuring setup (A 1000W/m2 area) I can't measure that. However, on good sunny days I have measured 1.1-1.3A short circuit.

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.

Its 100A max input which would point toward 6gauge if you want to provide full current capacity. I however used 8guage as I'm only pulling maybe 60A max.

The voltage I measured is .55 volts per cell (open circuit) and I have measured short circuit current of at least 4 amps under less than ideal conditions. I expect more current when summer returns and the sun cooperates! Also note that I live in the Seattle area which is not exactly equal to Phoenix!

I don't have a current clamp for my multimeter to measure it, nor the schematics of the device to assess whether or not it it would draw any current. If I lost any electrons then I would be positive!

I think there is a typo in the title. It's a 125 watt solar panel. I added a second panel and wired directly into my rig where my generator had been hooked up. I think the 110 you might be seeing are volts?

Is this the only panel in the circuit? If yes you could use as little as 10 amp charge controller.if you plan on adding I'd total the amps your panels produce....

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?
383733
I don't know the exact amount, but not much. I have it plugged in to a 15 A circuit and it has never blown the breaker.

Well the best i can describe is...The meter needs 5 volt min to operate( small red and black on back of meter).Then your solar panels would go thru the Shunt or other 2 heaver wires. This meter has a internal Shunt(big heavy12 guage wire in a loop on back of meter)To measure currant up to 10 amps..Google the part # !

I measured the current of a 1 m. Section at .25 amp. So 5M. Should be 1.25 A.

How many amps of electricity the panel will produce depends on the amount of sunshine falling on the panel. With this panel on a bright sunny day I was getting between 2.3 and 3.0 amps with a multimeter. For me it has been a great panel for camping.

I'm surprised no one has pulled out a multimeter to test this, and if I purchase one of these I certainly will... From my experience with similarly-sized relays and looking at other isolators, 500 milliamps would probably be a good guess, but assume 1 amp to be on the safe side

Thanks Peter;I'm interested in your approach - but can't follow your text description. Could you provide a 'diagram'???I also have EE background - would like to try metering my clothes dryer(220VAC).BTW - do you have a recommendation for a 'whole house' WAM?? preferably with logging, USB capabilityRegards,WT

Yes, I am busy using it to indicate the charge coming from a bank of solar panels. I am going up to a max of 42A (using the 200A shunt) - it does not seem to give a reading at low currents e.g. 1A but once it goes over this it is pretty accurate. I am using the battery that I am charging as the supply and it works fine.

1040 watts at an 80% efficiency factor or about 800 watts at 100% efficiency factor. 800 watts = about 40-45 amps at 12 volts which gives you a safety cushion of 15 amps with the unit. if you are going to run the unit at 24 volts, your inputs would be higher since as voltage rises with solar, your amps are usually cut by a factor of about 30-35% at each voltage increase(12/24/36/48 etc) without knowing what your panels are rated at, i cannot answer the number of panels question. just multiply your panel wattage by number of panels= total wattage. hope this info helps you. i can tell you this tho- i was pumping over 40 amps continuous into the unit when first hooked up and it wasn't even getting warm!. very well made unit/even better that its made in America and buying it supports other fellow Americans.

this interested me so i grabbed my meter on my lights goes from max of 800 ma full on to 10ma lowest setting but im not running a whole roll of leds. so far I'm real happy with this thing.I'm running accent lighting with it controller is rf so do not need line of sight to module.
