Do I have a solar panel problem??

Hi All,

I'm new to this solar power stuff and I'm also a bit confused so I'll try to explain :-)

I've just bought a 120W bi-fold solar panel which comes with a Projecta 10A regulator. The regulator has a voltage readout and 3 L.E.D's

Red - voltage available from panels
Yellow - battery being charged
Green - battery is charged

Now I though I'd see how the panels work before I take them away over easter. I hooked them up to the auxillary battery which was fully charged and had no load on it. The display very quickly showed 14.4 volts which is the voltage where I believe it should go into float charge.

I now expected the green LED to stay on but it kept quickly cycling between Green and Yellow while the voltage went up and down between 14.4 and 13.4 (the cut out and cut in points).

While writing this I've been informed by someone from the company that this is how the regulator should work. Still, I'm a cynical sort of person and I'd love to hear that someone else has this setup and it behaves the same way.

Thanks for reading!
