If I were in a campground longterm and was paying for electric my solar would be carrying as much of the load as possible. Having the hybrid inverter would make extremely easy.

The panels magically move to take in the sun, but I'm not sure how.
Nothing in that picture gives any indication they can move by themselves.

There is a meter loop on the pedestal. Perhaps he has a deal where he pays for the 120V he uses. Or, he is just trying to save the park some money because he has the solar to help - a little.

Oooor, he uses the solar to power a small heat plate for the Ranger Bob Mobile Meth Lab.


Nope. Electric is included in the site price, except for annual users and his is not an annual site.

Now, saving the park some money, that's one that didn't occur to me.

Regarding the meth lab, I think I'll go up to the office and see if I can move, like far, far away!


Today is my personal best for most consecutive days alive.

That small of a solar setup wouldn't power much of anything, let alone a heat plate. But I'll recognize the humor!

The panel shown is maybe 200w rated, so if he is lucky, he might get 1kwh per day out of it. Assuming no losses (there will be losses), that's about $0.15 per day saved (feel free to update with your local rates but it's still nothing).

Even with your very large 1300w system, you are looking at something around 5-7kwh, so maybe $1/day. How much do those fancy hybrid inverters that can mesh with shore power run?

With charging wire from solar panel going through front access they are probably keeping a starting battery from completely discharging, when plugged to shorepower many rig's only charge house batteries.

The most likely guess is that he's charging the chassis battery (maybe he runs his stereo from the chassis battery). But based on the apparent age of that RV, my second guess would be that his power converter is broken and not charging, so he uses solar to keep the house batteries topped up so he can run 12V gear in the RV.

Perhaps the owner of the panels wishes to do his small part to lower consumption. I always leave my panels on when on shore power.

I unplugged my converter 8 years ago when I installed my solar. It has been a couple years since I have be in a RV park but if I was my batteries would be charging from solar not the power post. I most likely would be plugged into the power post to run a heater or air conditioning.
