G,day to all

My old faithful Sun-tech 80 watt solar set up let me down two weeks ago on a beach, after couple of days the engel stopped working (Beer went warm) and I worked out the panel was not putting out any amps.

Quick check showed it was the regulator, so straight onto ebay and a new regulator was bought.

The old regulator was simply a box with two wires coming out with two alligator clips for connecting straight to the battery, no lights or charge indicators etc.

Now this new regulator has the following warning "Damage will occur if the battery is not connected prior to the panel being activated" Does this mean I would have to unfold the panel in the dark connect up the battery clips and then hey presto put the panel in the sun (Okay over the top but you know what i mean)

It also has two connections for a power output from the regulator (Load) does this mean it can run low amp gadgets whilst it is on.

thanks

When I first got mine was told connect the batterey first and have done that since.
Think it was a Morningstar regulator.Now have a Stecca and still follow that rule.

Most of the early style regulators were simple discrete component designs......I designed a crude one back in the 80's......what you connected when realy didn't matter if the design was good and robust.

Ya might have got some excessvoltage here or there and maybe some sparks on connection so it was probably a good idea to connect the battery first or cover the pannel.

But now, even some of the cheaper units are quite sofisticated and contain a microprocessor.

I expect that the one you have the smarts draws its power from the battery, its important that the smarts are powered up before you connect the voltage from solar pannels.

this is what I would do...

unfold the solar pannel and lay it face down on the ground.....hook up the battery and turn over the solar pannel.

My understanding of the load connection on my regulator (though I've never used the function) is that the power still comes from the battery but there a preset low voltage disconnect which will cut power below a certain voltage to protect the battery. The manual says it is for low power applications such as night lighting and in fact it can be set via dip switches to turn lights on and off automatically for preset periods daily.
The only time I made a mistake was when I thought I was wrong, but I was mistaken.

You should connect the battery firstly, and then connect the solar panel. connect the battery means that the controller recognize the voltage of system.
