TESTED: Offgrid Trek 215w Solar Blanket Bug Out Kit

I’ve been going back and forth trying to decide between adding a dual battery setup to the Jeep, or finding a better solar option for “unlimited power” when stationary.  Like most of you, I need peace of mind running the fridge in camp and easy access to power for charging USB devices. At Overland Expo East 2019 I ran across a veteran owned Canadian company that makes serious expeditionary grade kits that are ready for hard use in all weather, right out of the box.

Off Grid Trek makes solar blankets that feature durable panels with SunPower Gen 3 Maxeon EFTE coated solar cells. Imported from Japan, the EFTE coating (Ethylene tetrafluoroethylene, a thermoplastic copolymer) adds physical toughness to the cells which adds to their lifespan, and also enables better transparency than the normal PET coating used on many panels which increases output in the same light conditions, resulting in a whopping 23.8% efficiency. Many companies are using cells that only get about 15% efficiency under the same conditions so these panels are actually quite stellar in their performance.

Clearly, solar panel efficiency, power output, and durability has improved considerably over the years, and I’m simply amazed to be able to get 200+ watts from a 13-pound solar blanket that when unfolded measures 68 x 36 inches, and only 12.6 inches square when folded up. This is much smaller than our older 120 watt Power Film solar blanket. I was also pleased to see the use of Anderson connectors and heavy duty, 5-millimeter wiring used throughout the kit. This heavy duty wiring reduces voltage drop under peak charging conditions, and increases the lifespan of the harness overall.

The main wiring harness measures 16 feet long, so use on a roof rack, roof top tent, or even hanging it in an adjacent tree is no problem. The harness is also what I call “GI proof”, meaning the Anderson connectors only connect one way so if you can follow the simple instructions on the solar controller, and if you can tell the difference between positive and negative at your battery, wiring it up takes all of 2 minutes with a frosty beverage in one hand. So easy an Overlander can do it.

For me, all this information validates the fact that this Canadian company is making panels that work even in Canadian conditions – without direct sunlight and even on cloudy, rainy, overcast days. Most panels today stop working in these low light conditions, and it’s been my experience that when inclement weather hits I really need the capability to keep my batteries full. The heavy duty materials used in this solar blanket also impact it’s capability and durability in severe weather – I have zero concerns leaving this out in extreme conditions like I’ve seen in places like Death Valley or the upper peninsula of Michigan which is an important consideration for me when choosing equipment that I have to depend on.

The next two photos were taken at 4pm in November (sunset at 4:51 pm) with cloud cover and the sun dipping beneath the trees to the west… 

And there’s something we don’t always see, almost 1 amp still going to the battery right to the very end of sunlight in marginal lighting (fridge off in this picture so no power draw). Not bad at all.

Beyond the solar blanket itself, power needs to be controlled before connecting to your battery, and the 20 amp common positive Maximum Power Point Tracking (MPPT) solar controller is a critical part here in any solar kit, optimizing the voltage matching and current between the panels and your battery.  The unit provided by Offgrid Trek features a backlit, day and night readable LCD display, and both the solar blanket and solar charge controller have two high speed (2.2A!) USB charging ports each so you can charge up to four devices at a time right at the source. This well thought out feature works as advertised and saves your vehicle battery for starting the engine while negating the need for a portable battery pack if you choose to just use the kit for all your charging needs in camp like we do.

Our main power draw concern is our Engel MT-45 fridge, it needs 1-2 amps total in camp, so I’m confident that even under low light conditions this solar blanket is up to the task. Using this in our driveway for the first time, we saw this solar blanket produce 11 amps under the full Florida sun at noon, more than twice as much as our Renogy 120 watt panel makes under ideal conditions. These numbers mean this kit makes more than enough power for any SnoMaster, National Luna, Dometic or ARB fridge on the market while still topping off your battery too.

This kit requires no hard mounting of any kind so it can be moved between vehicles with ease, and it packs down small enough to be easily portable in the included, made in USA bag from Overland Gear Guy.

Some improvements I’d like to see would be a traditional, automotive style replaceable 30 amp fuse at the battery connection as well as a more versatile mounting system. The included carabiners are high quality but don’t lend themselves well to use on or near vehicle paint or the variety of cargo racks or trees etc that the solar blanket needs to be affixed to securely. After a few set ups and tear downs of the panel we ended up setting the carabiners aside and started using some reusable Nite Ize rubber twist ties we had laying around – problem solved. 

The bottom line:

I think it’s pretty plug and play as is, and most importantly this kit just works. It provides more than enough power even under marginal conditions to keep our fridge going for days on end. And while it may not be the least expensive option, it actually does perform as advertised in a variety of lighting conditions and weather that may render those lesser panels ineffective. It also delivers value added when the power goes out at home during a hurricane, fire or earthquake. That peace of mind alone makes this an easy one to recommend to our members. Check out Off Grid Trek for more info on this and other power solutions.

FULL DISCLOSURE: Off Grid Trek provided this kit to the author at no cost for the purpose of this review on American Adventurist.

Utah Winter Adventure – Part I of III

In the past few years, we’ve taken to planning a small annual trip that lasts approximately a week long during the winter time. Destinations are unknowns (new to us) and planned throughout the year as rough locations and POI’s that we would like to hit. Routes in between are roughly formed and there are times where we improvise and have to call an audible.

Our previous trips: Death Valley Expedition 2015 (DVX15) and California Coastal Expedition 2016 (CCX16), and many other small trips to Anza Borrego, Trona, Thomas Mountain and other sites, have really helped us form a template as to how our trips are planned, what works and what doesn’t. Our plan for the winter of 2017 had us traveling from our home base in Southern California through Nevada, Utah, and Arizona. We wanted to utilize as many dirt roads as we could, while also hitting certain POI’s, so hardball wasn’t entirely out of the question. This is what we came up with for our Utah Winter Expedition 2017 (UWX17):

Day 01- A Late Start with a Late Entrance.

After a late start of last minute packing and getting ready, I hit the road about 4pm on my way to the meeting spot just north of Lake Mead. I linked up with Cris and family at the El Cajon Pass McDonald’s right around dinner time for a quick meal. We hit the pavement hard and arrived in the area just before midnight. It was pitch black dark and all we had to navigate by were maps and the GPS point. It took us a little bit to find the exact camp spot, but we eventually found it. Everyone had already called it a night and had gone to sleep, instead of waiting for us, so Cris and I quietly setup camp and called it a night ourselves.

Day 02- A Dusty Blast to a Wrong Whitmore

We awakened to a very chilly morning, but were instantly rewarded with an awesome view of the lake. We had camped in the dark just above the lake shoreline and it paid off now with a spectacular view of the entire area. We had a comfortable start to our day and enjoyed the area while eating breakfast before we set off. We had a driver’s meeting to go over the day’s route, which would be Whitmore Canyon just on the North side of Grand Canyon.

We set off just before noon and headed up to St George, Utah to restock and make last minute meet ups. We made a nice stop at Walmart and had lunch before we proceeded south and hit the dirt. The dirt road in was a good one, dusty but well maintained. We blazed in towards Mt. Trumbull and hit the school house to reconvene since we became so spread out along the way. The wind was nonexistent so our trail of dust was so thick that visibility was near zero in places.

Continuing south as the sun began to set, we took a wrong turn and started gaining elevation instead of dropping down to 1500-ft or so where the overlook is. We doubled back towards the trail split but opted for a nice, safe, open spot along the way since darkness had already arrived, the first of several unplanned audibles on this trip. We set up camp in the dark and started the campfire. A bright moon rose over the mountain as we had dinner, and it would continue illuminate our night skies for the rest of our trip.

Day 03 – New Years Eve at the Correct Whitmore Canyon

We woke up to another sweet view as we camped just a short stroll to a cliff side, which opened up to a beautiful view of the valley below, and the road we were supposed to be at last night. The sun had not yet crested the ridgeline, so the weather was chilly again. It was a calm morning as we had time to explore the immediate area on foot and view the spectacular valley below us. We gathered just after breakfast for a driver’s meeting to make a call on where to go next. The general consensus was to hit the spot that we totally missed the previous night and spend the rest of the day there. It ended up being a great call.

We hit the road around 11am and began the short drive to Whitmore Canyon. The road in was smooth but turned to slow and rocky. It eventually led us to a breathtaking view of a portion of the Grand Canyon. There was a slow, rocky switchback descent into the campsite. Cris and Jon led the way and setup camp as we all made our way down. The camp site was just terrible (read sarcasm)…  It was right on the cliff’s edge above the Colorado River with a 180-degree view. This was a perfect day. We all got settled in, made lunch and relaxed the rest of the day.

After lunch, a few of us relaxed around the fire ring, while Andy and I made the hike down to the bottom and the Colorado River. It was about 45min, 917ft down, and about 1.2miles one way. It was a great little hike to see the river and experience how the views changed as you make your way down. The water was definitely chilly but refreshing. Oddly enough there was a cactus garden right before the water’s edge, so maneuvering to the water was a bit tricky without getting poked by the many needles.

The hike out is always tougher than the hike in, but we got back into camp just before sunset and joined the others relaxing around the fire ring, just in time for appetizers, cold beverages, and dinner.

As the night went on and we were enjoying the campfire, we saw a set of headlights coming down the hill that we rolled in from. We became very hesitant when they rolled straight up to our campfire in the middle of our camp. Two guys walked out, cups in hands and a decent slur in their talk. As they were introducing themselves, and us keeping our distance, a third guy came out as well.

Luckily they just came down to make themselves known and told us that they were going to setup camp not too far away from us. They thought we were someone they knew as they were meeting someone down there. They left our area and rolled about ¼ mile away and setup camp. Later that night as we were still around the campfire, we saw another pair of headlights coming down. We walked out to meet them in a somewhat defensive position so they wouldn’t roll into our camp. They found their friends and we continued our night a little less relaxed. We called it a day as one by one, we left the fire and went to bed.

Day 04 – Attempting to Beat the Setting Sun and Rising Moon

We awoke to a another splendid view with an epic sunrise, so we decided to take another easy morning. We soaked in the rising sun cresting over the canyon as we had breakfast. After a comfortable start, we decided to get our trip on the road again. But before we headed out, we decided to take a group photo of this epic campsite so we staged up on the cliff’s edge, and snapped a few for the books.

 

Once on the way out, we doubled back from where we drove in. We hit the 4-way intersection at the schoolhouse for a quick break around 11am. We reconvened a quick driver’s meeting to discuss the route and the rough area of where we would be heading to. We decided to head east after talking with a local as they said it is much more scenic than double backing the exact way we came in to get back on the highway.

Mt Trumbull Loop was extremely scenic with a steady incline in elevation. Once we hit the top, we drove along the ridgeline for a bit until it opened up into flatlands and a nice wide-open fire road. Once we hit Antelope Valley Rd, we hit the gas and zoomed our way back to Highway 389, a very smooth and great driving road. Definitely one of the better dirt roads of the trip thus far. We aired up before we hit the pavement and we hit it hard towards Kanab for our late lunch.

Once we entered Kanab, we decided to hit up a burger joint which was VERY good. After filling our bellies, we all split off for different errands to run and decided to rendezvous at the market before we hit the road again.

We hopped onto the road after a long but relaxing pitstop as the sun was beginning to set. Jon had a site set in his mind, so we followed him up Hwy 89 to Hancock Road towards the Pink Coral Sand Dunes. We drove around a bit through a very scenic fire service road with a full moon rising over on the east, and the sun setting in the west. He found a spot, but it was small and along a hillside. Not very spacious for all of us to camp in. I scouted around being tail-gunner on offshoot paths we had passed but couldn’t find a tangible spot for us all to camp in comfortably.

With night falling very quickly, we double backed to the main road and found a campsite along the road from which we came in. It was a large spot and about fifty yards off the road with good cover. We were happy with this spot so we setup camp and enjoyed the night while waiting for Brian to link up with us that night.

To be continued in Part II…
