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.

OR Winter Market 2017

I’m not sure that my pedometer is accurate, but I am sure it’s accurate to say that it takes many steps to see all of the awesome products that congregate twice a year in Salt Lake City, UT; where the outdoor industry hosts Outdoor Retailer. This is the event where exhibitors come from all over the world to reveal their new products, and showcase their existing products for retailers and industry media. The Winter Market obviously caters to skiing, snowboarding, and other snowsports—but there are hundreds of products on display that can be used year round.

I walked the miles of red carpet looking for gear that would be of interest to the American adventurist, so please let me know in the comments if there are things that you want me to focus on for the summer show. Now, without further adieu, here are the products that will be lightening your wallet in the coming months.

Adventure Medical Kits

Adventure Medical Kits (AMK) has reintroduced their Mountain Series of medical kits, which set the standard for backcountry medicine when they were originally introduced 20 years ago. Each kit is organized by type of injury, and AMK makes refill kits for each compartment, making the restocking process a snap.

Beyond Clothing

Beyond Clothing is the brainchild of some of the fine folks that played a key part in the development of the Protective Combat Uniform (PCU) program for the US Military. Utilizing top shelf American materials (yes, everything is USA made), Beyond offers a complete layering system that will keep you comfortable no matter what mother nature throws at you.

Big Agnes

How do you make an ultra-light sleeping bag even lighter without cutting down on insulation or compromising durability? Simple. You take the zipper out. Big Agnes has replaced the zipper with a clip system that allows you to close the bag up just like a zippered bag when you want it, and open it up when temps do not require full mummy mode. If you’ve ever caught or broken a lightweight zipper, you need to check out Big Agnes’ new zipper-less bags.

Black Diamond

Black Diamond’s latest update to their awesome LED headlamps packs even more lumens into many of their range of proven models.

Cascade Designs

MSR’s new four-season tents look great and I’m hoping that I’ll get to put one to the test this winter. The Advance Pro 2 is designed for aggressive alpine missions and can be easily setup be one person in technical terrain. The Access Series brings vestibules and other great features to the game and comes in a one, two, and three person version.

Darn Tough

Socks with a warranty—It’s a thing. If you manage to wear out a pair of Darn Toughs, simply send the worn out pair in and Darn Tough will send you a new pair. Their line covers everything from Ski socks to lightweight running socks.

Garmin

Garmin recently acquired Delorme, and they’ve been busy updating the InReach series of satellite communicators and many of their native products. New to the Explorer+ is a TOPO map, making the navigation functionality of the device much more useful. Maps are also making an appearance on the new Fenix 5 series of watches which pack an insane amount of capability into a lightweight watch.

Goal Zero

I’m really excited to get my hands on Goal Zero’s new generation of Yeti Solar Generators. Lead batteries are out, and higher-capacity Lithium Ion batteries feeding much more powerful AC inverters are in. There’s also the Fuel, a 2000-watt gasoline generator that I’m told is Honda-quiet. Other new goodies include the Boulder 100 and Boulder 50 rigid panels.

Groove Ring

Silicone wedding bands are a great option for folks who find themselves scratching and wearing their metal wedding bands down during abrasive activities, and they provide several safety advantages. Groove Ring takes these benefits a step further by allowing the skin under the ring to breathe, which drastically increases comfort.

Helinox

New from Helinox is the Chair Zero, a sub-one-pound collapsible chair that will hold folks up to 250 pounds.

Hydroflask

Hydroflask now offers their proven double-wall insulation in a bottle and cup designed specifically for folks who want to bring wine into the field. The new products feature insulated, food-safe lids that won’t impact the flavor or characteristics of your wine.

Leki

Known for their awesome trekking poles, Leki now makes the XS Lite Table that will allow you to set a beverage anywhere on the table’s surface without gambling on whether or not said beverage will tip over as soon as you look away (because: it’s not fabric).

Mountain Smith

Mountain Smith partnered up with renown lensman Chris Burkard to develop the T.A.N. (Tough As Nails) series of camera bags. Three sizes of camera cubes are great for packing your kit into a larger pack that you already own, and there are two complete packs if you want an all-in-one solution for carrying your gear.

Osprey

New from Osprey is a comprehensive line of products to help you organize your kit for travel, and a line of bomber luggage. According to the Osprey, the new luggage has passed the ‘bags keep their contents dry when placed on a roof rack and driven in the rain test.’

Sea to Summit

Sea to Summit makes everything from collapsible cookware to inflatable pillows, and about 5 million things in between. Their offerings are very well thought out and very innovative. They recently launched a hammock that weighs 4.9 ounces, yet holds 300 pounds. Their new luggage allows you to configure the carrying handles as a backpack, shoulder sling, or as traditional handles.

SOLE

Not only does cork do a great job of keeping bottles closed, but it turns out it is also a great material to recycle and make footbeds and shoes out of. SOLE’s new cork-based products offer several advantages over their EVA predecessors. According to all of their professional athlete testers, the cork footbeds work better than EVA footbeds.

UST

UST has created a lighter that doesn’t create a flame. Instead, the TekFire lighter arcs a current between two poles to set things on fire. The unit is powered by a Lithium-Ion battery and charges from a USB port. UST Survival offers a comprehensive line of survival products and kits.

Western Mountaineering

Western Mountaineering makes some of the most highly regarded down products on the market. Their offerings are known for their outstanding performance and very long lifespan. Western has started having the folks who build their products sign them—just like a hand built motor from AMG.
