Portable Solar Smoking

Although that may occur to some solar controllers, the one that came with our Renogy solar suitcase does not have this issue. There is no way you can connect the portable solar panel to your battery without prior exposure to the sun, our unit comes in a padded black case and the second you unzip it both panels are fully exposed.

Just start with a new controller, water proof would be better as I lost one to a passing flash storm common here in the Mountain West. Since you inherited it double check wiring before connecting new controller in case it has been fiddled with. I find our portable panel can really keep up with what we already have on the roof being that we can reposition it a few times a day maximizing periods of peak output.

If the instructions didn’t mention the battery first thing, that controller would have to not care, as I’m sure many purchasers would open then connect. All the controllers I’ve seen do proclaim battery first, but obviously I haven’t seen ‘em all. Still, smoking wires are always a bad sign.

I used a 120 watt suitcase kit with the controller attached to the back of one panel for years and I connected the batteries to the controller after I had the panels set up. I never had a problem and never heard anyone mention having to hook up the batteries before the panels were exposed to sunlight.

Instructions don't mention this either, just says plug into port or connect to batteries. I'll buy a cheap controller and try again.

And here I thought this would be about how to smoke meat using a solar powered smoker........

Yup.

Must be fun setting that up each morning. Unless you go to town for lunch. Then you get to set it up after lunch too.

Probably is garbage now. Controller must be hooked to battery before any solar. Usually that’s taken care of by hooking controller to battery, THEN hooking panels to controller. Shut down by disconnecting panels THEN disconnecting battery. Since panels produce a small amount of power even in dim light, there’s no room for error. If there’s smoke, something is burnt up.

This is great info. I'm planning to get a 300w suitcase type unit with controller to supplement my 300w on the roof if we get in a shady place. Who knows what order I may have hooked it up in. Good info for sure.

Thanks,
