I NEVER use the current scale on multi meters. I put some kind of shunt in the circuit, or use
a clamp on meter. No interrupting circuit operation, and no smoke. Bruce Roe

Parallel panel amperage problems?

I did what you suggested but received no reading.
Sorry if I'm fumbling this guy's.
You also probably need to manually set the meter to the 10A range instead of depending on autoranging.Last edited by inetdog; 02-12-2019, 04:02 AM.Leave a comment:

Sdold,
They are Panasonic 330w panels, VBHN330SA16
Thank you for your helpLeave a comment:

They only produce power during the day, primarily at mid day. You might see some voltage under low light conditions, but little or no current will be produced. Try it tomorrow around noon. In fact it would be educational to connect the ammeter early in the morning, and watch the value rise as the day progresses. You'll see how little current is produced in the early morning, and how you really get the majority of the current closer to noon. It's OK to parallel the panels for this as long as the sum doesn't exceed 10 amps.Last edited by sdold; 02-12-2019, 01:29 AM.Leave a comment:

Sdold,
No it's night time. The pictures I took above were at night. We have alot of light pollution here so I still get some readings.Leave a comment:

Inetdog,
Sorry I meant to specify that it was suggested to take a reading while the system, not circuit was completed with a charge controller and battery but I'm still wondering is if I'm going crazy or not if I m correct in saying that readings direct from the panel while in parallel should be a combination reading of the two?Leave a comment:

Plug your red test probe into the 10A jack, it looks like you have it in the V jack.Leave a comment:

I'm just currently testing the panels themselves. I was just curious if the no increase in amperage while connected in parallel was a result to me taking the readings as an open circuit and if completing the circuit would result in the correct amperage

If you are measuring voltage and current at the same time you do not have either an open circuit or a short circuit.Leave a comment:
