Amps being generated by solar panels

Collie

Initially the voltage of the solar panel will be well above the voltage you have stated.
However, when connected to a circuit the open circuit voltage is now reduced to a level which will be controlled by two things assuming all wiring/connections are good/correct.

The flow/amps ability of the panel which is delivering energy to the reg and battery.
The resistance presented to the panel by the regulator and the degree of discharge or resistance of the battery.

The fact the 17v of the active panel is creating 14v at the battery proves there is some current going into the battery. Only a voltage which is greater than the battery can raise its voltage level. Therefore there has to be a current flow happening.

The current flow will be above the low ranges on a multi meter and most/nearly all multimeters require the positive lead to be placed into a heavy internal shunt position. This is usually either marked 10A or 20A. If this selection is not made then the meter will read an over range if still plugged into the low sphere of operation.

The heavy section is internally fused, and it is common for an inadvertent connection to blow the internal fuse and until the meter "has the back off" and the fuse replaced it will not read the high amp range. The blown fuse situation can be checked with another meter set on low OHMS.
I think your problem lies in here somewhere.

Collie,
have a look here.

Remember you have to place a multimeter in series with the load as shown in the diagram.

A far simpler way is to get a cheap tong tester to measure the current. Make sure you have set any of the instruments on the correct settings before using them.

I think jaycar sell a cheapie for around $60

Collie,

I'm no expert - but from what I observe it can be hard to measure current because of Pulse Width Modulation from the controller. I have tried many ammeters. I have an old analogue (true) ammeter where the needle just vibrates away. And my DMM and Tong ammeter give a reading that's constantly changing. My EFlite digital meter gives a smooth reading - must average things out a bit more.

I'm guessing the problem is worse when the battery is fully charged and the current is heavily regulated.

I Purchased a Powertec solar controller, from the local Jacar Store, (the owner happens to be a mate of mine)

The difference was amazing, and he then gave me some tips as how to interpret the findings, and how to get it running more efficiently

Hi Colie,
We are currently sitting in the Cook Islands ans there is sun to burn here,
in response to your question we sell a battery monitoring system.
have a look at our home page.

I do not have any costings with me but if you are interested I am able to forward on my return to Aust early Jan.

The system consistes of a meter remotely mounted and acurrent shunt to measure current flow into or out of the battery, as well as voltage,
Beats getting the vlot meter out and setting up to measure current etc.

regards

Geoff
