How fitting it is that I’ve put this post off long enough to coincide with Earth Hour – when everyone is supposed to turn off their lights for one hour at 8:30 tonight in a showing of global showing of solidarity for energy conservation. But let me tell you, Earth Hour happens every night around the LiveWorkDream rig!

Shortly after we returned to Slab City, we got fed up with killing our batteries every evening. And coincidentally, I had just completed a design project that enabled us to afford an upgrade to our RV solar power system. But what to upgrade with the budget we had? That was the big question, so we went and saw Solar Mike.

Our original system included one Evergreen 120w solar panel rated up to 7.6 amps. Considering we draw about 10 amps when using our satellite internet connection and charging our laptops, it’s really no wonder our batteries would often be drained at the end of the day – even if the sun was shining bright. Simply put, we were just using more juice than we were making even on the best of days.

So back to the question at hand … what to upgrade? We had the opportunity to rebuild an Outback MX60 MPPT charge controller – and still do – which would give us the boost available from Maximum Power Point Tracking for about half the price of a new controller. But that would still only buy us another amp or so.

So, we took Mike’s advice and added another panel. While we were at it, we modified our existing mounting hardware to let us tilt both panels for maximum solar exposure, all day long. And now we’re making too much power!

Our new Kyocera 135w panel is rated up to 8.3 amps. During our entire stay over at Anza Borrego, I don’t recall running the generator once. But that changed yesterday. It was a beautiful day for making power. The sun was shining bright, a steady breeze kept our panels cool, and we drained our batteries by the afternoon. Huh? That’s what I said!

Upon investigation, I discovered the batteries were not only dead, but there was no status LED blinking on our C40 charge controller. Great, I thought, now we’d have to stay until next week and take the rig over to the Sun Works to find out what was happening. Then I discovered we had just blown a fuse!

The 15 amp Buss fuses we had protecting the controller were more than sufficient for the single Evergreen panel we originally installed. But with the recent upgrade, we had apparently peaked at more than 15 amps of power being generated at some point! Not bad, not bad at all. Now if only we had the battery bank capacity to hold the extra power allowing us to work a few more hours into the night. That upgrade will just have to wait until we return to the Slabs and go see Solar Mike again next year.

My only regret was not asking Mike about a trade-in of our first panel before we started remounting it. But with the price of panels coming down, he assured me we wouldn’t have gotten much for it.

Yes, solar panel mismatch is something to consider – it’s not just aesthetic – but in an RV system like ours, where squeezing out every bit of possible power in a limited space on a limited budget, it is as they say … what it is.

Besides, the two tilted panels still look pretty cool! And yes, we did consider the swing of the arm on our F2 Dish when re-installing the panel. To my surprise and delight, it clears the elevated panel with room to spare. Now whether or not it does so next time we are way up north is another story. Let’s hope by the time we get back to Maine, we remember to check the panel before stowing the dish.

If you’re seeing this post, then we have successfully migrated to our own dedicated server. You may not be since DNS changes can take some time to propagate throughout the world, but I digress.

We’re still working out some kinks so feel free to report any technical difficulties. Thank you for your patience and continued support!

Anyone who ever wants – or needs – to raise funds for anything online should definitely check out this ChipIn! widget.

We’re collecting contributions over at tripawds.com to help fund our first managed server hosting account. The community on Jerry’s site has grown beyond our current shared hosting plan’s capabilities. And it showed as poor performance in the Tripawd Discussion Forums and Chat Room.

So, Bob is provisioning our new dedicated server. Soon I get to learn cPanel and endure the WordPress migration thing for the tripawd blog and move the Simple:Press forums. That means this site will follow. Expect downtime over the upcoming week. Thank you for your continued support.

Ever since we got our rig, we’ve been fortunate to have a wealth of information at our displosal. I’m not talking about the obligatory gaggle of retired full-timers who gather any time you attempt to back up your rig. I’m referring to our rig’s solar power system.

My brother in law Rich O’Connell is a brilliant electrical engineer. He has grown a successful solar business with my sister, built his own off-grid home, designed multi-gigawatt systems, and patented a solar panel washing system. He also designed the RV power system we rely on for boondocking.

Recently, I got to meet another expert; Solar Mike. He operates The Sun Works from his solar powered rigs on the slabs. Mike knows the DC side of the business and how to get the absolute most out of what you got.

That’s why I was happy to be at Slab City when we considered upgrading our system. I had access to experts from extreme ends of the solar industry. Either one of them could have easily told me I had a bad battery. Which I would have known, and could have avoided, had I been servicing my batteries as they required.

It just didn’t seem like we were getting the run time out of our batteries that we expected. Loving to boondock as much as we do, we explained our issue to Mike and asked him for an estimate for upgrading the system. He immediately discovered one of our batteries was weak, and pointed out how dry it was. Bone dry.

Yes, for you long time readers out there, we did learn this lesson before.

I might have kicked my feet and mumbled a bit, but – don’t tell Rene – I still think it was worth the $95 we spent on two new batteries to have not been pulling them out and checking them every month for the past year. Truth is, we just forgot.

Yup, our upgrade cost us less than a hundred bucks. And it was so cheap because Mike took our good battery as a trade-in. The ones he carried were a bit better, and I wanted a matching pair. Not bad since we were considering spending over a grand on couple new panels.

Had we spent the $4000+ on the original system design Rich gave us, we might have never even had this discussion. But having worked this over with Mike, I now know where in our 24′ trailer we can fit six maintenance free 6 volt batteries – much better suited for our use than the two 12 volts we have.

And having done it a couple times now, I know it’s not such a big deal to pull our batteries and check on them. We even carry some distilled water now so we have it when needed.

I also know now that an MPPT charge controller is where we’ll invest our dollars the next time we complain about our system. That’s one thing Rich and Mike both agreed on – that any Maximum Point Power Tracking charge controller will boost performance performance of our PV array. Then we can start talking about boosting the battery bank and adding panels again.

When we will make that investment is the $3000 question. But that all depends on where we’re going to be purchasing property come Spring, and whether we will need to upgrade what we have or build a larger off-grid system in a shed or trailer. And we’re not even sure where we’ll be next month.

OK, so far so good with our upgrade to WordPress 2.7. No fatal PHP errors or major incompatibility catastrophes. This is a good thing.

But we haven’t yet upgraded the theme which is probably why your saying, “What’s the big difference?” But with so many hard-coded theme template modifications, I may not upgrade Mandigo anytime soon. The new version does have some pretty cool new features, but I think I’ll just quit while I’m ahead here and get to work on Jerry’s site to see what can of worms I can open with the Discussion Forums upgrade.

You can consider this post just a test drive of the new WordPress 2.7 interface, which I must admit is pretty sweet. And a test of our NextGen gallery and TrackPing plugins.

The only other change you may notice – if you ever used it – is the missing “Email this Post” feature. Well, the WP-Email plugin didn’t play nice after the upgrade so we’ve eliminated it. No worries though, the new Sociable plugin lets you email this post using the first “Share This Link” icon below.

Please let us know if you experience any new technical difficulties, or if your subscription feed no longer works. But then, I guess you’d never get this if it didn’t!
