Yup. I believe for people trying to survive a power outage on a budget that it's good to start with something small that can briefly power things as you need them, and then build more of them and/or bigger ones as you can afford to.
Cool. Hook that up to a solar panal. Connect a gravity battery to that rollig down a hill. Just run your truck for a few minutes every day.
Interesting. I might have to look into this. Thanks for the ideas.
I wish I could turn back the clock and build a cabin.... I have experimented with alternate power, heating and cooling and have built and tested quite a few systems over the years that work. Your cabin location has a huge impact on what's needed to power it, heat and cool it. You will find that electric heat, electric stove, even a small efficient heat pump, toaster oven, Instapot, air fryer, will run your batteries down very quickly. If you are in the trees, shaded area, snowy area, you won't be able to sufficiently solar charge batteries. Its even worse from November through March with low sun angle and short days. The trick to batteries is that you need to recharge them. I have a standby generator that is sometimes used to recharge batteries after days of cloudy stormy weather.
Heat....those $120 Chinese diesel heaters provide clean dry heat and use between 1 and 2 gallons of cheap red off road diesel fuel in 24 hours depending on the heat setting selected. They run on 12 and sometimes 24 volts, use around 35 watts, easy on the battery. Beats 1500 watts. I run one almost non stop from November to March. They have their quirks but are cheap, easy to repair. I buy 2 at a time as they are cheap. In January a fan bearing got noisy and I replaced the heat unit with the spare in 45 minutes.
A small wood stove also heats a cabin very well. I built a lithium battery backup unit for my friend's pellet stove to run during our power losses. I could see a pellet stove heating a cabin as well. For running water, a 12 volt motorhome water pump can be had as well as a propane fueled motorhome water heater. They make 15,000 btu 12 volt powered propane furnaces for motorhomes as well. Turn on the propane, set the thermostat, and forget it. Fully automatic.
LED light fixtures are a must. You can get 3 and 6 watt 12 volt standard lamp base screw in bulbs that can be installed in table and ceiling light fixtures and bypass the inverter losses. Or you can run standard 120 volt fixtures with LED bulbs and run a slide dimmer. We camp with a chandelier just for fun. We also stay in a primitive cabin on the ocean bluffs using a home built power box to run lights that we bring, a small microwave oven, and a dorm fridge with separate freezer compartment and cook with a Coleman white gas stove. Our van has 400 watts of solar panels, 300 amp hour lithium battery, 2000 watt inverter. I can recharge our battery pack up at the van and park it un the sunny area.
You are on the right track. But just like motorcycles, you can never have enough power! Your wallet is your limitation. And don't forget a smoke detector and carbon monoxide detector for the cabin, 10 year battery inside. I hope this helps!
This is amazing info! So appreciate you sharing your thoughts. We've walked through many of these ideas, but you've actually given me some additional ideas to run with, especially with the diesel heaters. Excited to see how our cabin comes along. We'll do our best to document the journey.
@@ScottsGarage I kept the lights on in 17 countries as an Engineer for GE in the 70's and 80's. I can't leave anything alone without tearing it apart and improving things! I'm retired and still build things. I like to have 3 or 4 backup plans to cook, get clean water, heat, cool, provide light, freeze food, etc.
Here is a diesel heater. It's main purpose is to keep Ma warm on the couch where she uses her computer. The duct to the left blows warm air on her. I added the LED fuel level light and installed a fuel filter inside. It runs off a lithium home built battery pack even after we lose the grid (3 times so far, 2 hours to 18 hours from January through March). Other neighbors went cold as central gas furnaces need 120 volt AC power to operate.

The Anker system IS an inverter. Why not just use some panels, a lithium battery charger, and the battery, then run the battery into the Anker using an XT60 connection? Just run directly off the battery lugs in parallel with the output from the battery charger. No offense, but this is what I'm setting up until I get a real inverter and more panels. I have a small Ecoflow river, and essentially I'm adding battery capacity and charging it with just a few panels. BTW, I'm a 30 yr electrician and was a solar installer years ago.
I 100% agree. We are going to run off of the Anker for as long as possible. Our big problem is our solar input. I can get a little trickle charge off of the two panels that we have right now, 250W each, but it's just not enough for a multiple day stay using just the Anker. We received these batteries for review purposes, and we're hoping they might add some extra back up until we can upgrade our solar input. What I found was that the inverter set up was not able to offer back up power to the Anker. Not sure why. Still researching the limitations. Thanks for your ideas.
Why do we use AC? transmission. A motorhome is all DC. a Cabin is not much bigger than a motorhome. Same for tiny homes.
Good question! Seems like DC is much more efficient. I'm obviously not an electrician so I'm sure there are some good reasons out there. It's so much more fun working with small efficient spaces and figuring out how to power them.
