I am not off grid but am making preparations for if the grid goes down (Florida, nuff said). Rural area, I have room for a ground mount and no neighbors. I do have a good sized budget and have blown most of it. 11,000 watts of panels, four 5.12 kWh batteries, and two 6,500 watt inverters. Building my own ground mount and doing all my wiring. Had to get some toys to make it easier, three point post hole digger for my tractor, no way will 71 year old me be able to dig 24 4 ft deep holes to anchor the mount poles in. I will follow you and let you know how I am doing. Got my inverters and new breaker panel mounted. Just ordered $850 worth of wire, breakers, and fuses to connect the batteries and inverters. While i wait on those I will start digging holes and putting up poles.

Pretty good simple summary. Higher output system you need higher voltages. Good Rule of Thumb 0-2kW system use 12v 2-4kW system use 24v system over 4kW systems use 48volt. consider you don't want to go above 160A due to wire sizes. Most people will eventually add more loads. If you start with 48volt you don't have to change the whole set up to go bigger later.

The great thing about DIY solar is that you can build to your needs. Becoming your own power provider is becoming easier and there are many ways to do it. From what i have seen it is only the minimalists that are ok with small systems. For the rest of us there is no such thing as to many panels......lol. I started out with 4 100w panels and a 1k all in one inverter charger for my garage four years ago. This morning i count 18 250w panels that are powering essential my whole house. It is an off grid system and it runs every day to reduce my power bill and provide me with power if the grid is not working for whatever reason. Looking forward to watching your journey here.

You're pretty much right about component costs per watt hour being comparable but the difference in 12v vs 24v when it comes to wiring costs is dramatic. It takes much larger wiring doing a 12v system & wire is thru the roof these days so going 24v can save big bux just on that.

If you want to add on to your system down the road, you would be far better off with a hybrid inverter system that you can piggyback more hybrid inverter systems on to. I would recommend using Signature Solar out of Texas to purchase everything you need to put your system together. I would also recommend using a 48V system over a 12V or 24V system, due to the high efficiency of the system as well as your 12V or 24V systems will be worthless if you want to use electricity on as many things as possible to save money for buying propane fuel, which is quite expensive. I made the same mistakes you are making with solar when started 5 years ago and would have almost $16K in my pocket had I listened and taken that advice. Good video presentation though with the exception that you left out the fuses and breaker switches.

The cool thing about solar is it is easily expandable, so you can start tiny and get a feel for the results. It will be real clear what you need more of for your personal needs. Its kind of addicting, once you realize the stuff actually works the confidence to plow ahead grows and your electric bill shrinks. And there is great information online like this video and more to answer almost any question.

I agree 100% it is far more simple than people realize. I've been running an off grid mini split that I installed with a little help from a HVAC professional. It was probably more fear than anything that slowed me down. The actual process truly wasn't difficult. The Midea U Shaped window units have been great as well. They take 30 min to install and they are relatively efficient. Don't need any kind of HVAC help either. I've also liked signature solar's products. Their all in one 3kw inverter/5kw pv input is a pretty solid value, but it's a 48v setup. Great video!

The other good thing about adding complete small systems is that the gear is evolving so fast, you will want to use the more modern equipment, and some of it isn't going to interface with the old gear. I've been saying for decades, if one big unit was better than multiple smaller ones, your body would be one giant cell. And it is safer and more economical splitting up all that power among multiple smaller systems.

I totally agree on having a little independent system for equipment located away from the house. I don't entirely agree with you on maintaining discrete systems within the house. I do agree with the redundancy argument, but it is also important to reduce complexity and maintenance and in particular you don't want to have to monitor multiple independent battery systems. When conditions get tight it can be a struggle. You can have redundancies even with just one integrated system. For example, if you have two strings of solar panels put each string into its own charge controller (like a Victron SmartSolar 100/20). So now you have redundant charge controllers. And you can put two (or more) 48V batteries in parallel... so now you have battery redundancy. This also gives you a lower-impedance DC bus that can absorb bigger surges without damage. And the outputs can go to more than one inverter so you have redundancy there too. Plus a few spares on the shelf. But only one "battery level" that you need to monitor, and all of your storage is ganged so if conditions get tight you just shut-off some equipment and now the whole system can be directed to remaining loads. On 12V/24V/48V... these days you should definitely go with 48V LiFepO4. The reason is that all the equipment for 48V is now VERY common, all the amperages you have to deal with are 1/4th that of 12V, the wiring sizes are 1/4th that of 12V, and most importantly, the heat generated from the equipment at 48V is 1/16th that of a 12V system. 48V is low-stress on everything. The charge controllers will barely even get warm. One last suggestion... fuse the batteries properly, and be generous with the DC breakers and disconnects. Make it easy to turn parts of the system off. And use double-pole breakers for everything. Don't just put a breaker on the "positive" of the solar DC in, for example. Also put it on the negative. Not only does this make working on the system a whole lot easier, but in situations such as a lightning storm passing through you really want to isolate as much of the pieces of the system from each other as possible. And don't forget the lightning / surge protection devices. Just electrically isolating the system won't protect the bits and pieces from lightning if you wind up with electricity dancing over the entire place! -Matt

@@offgridsolitude Unfortuntely, this is an area where the choice of 12V can shoot you in the foot. At 24V or 48V, charge controllers (such as Victron) don't need much ventillation. Same with batteries. Charging or discharging a 24V or 48V battery usually generates almost no heat within the battery, making summer heat a non-issue. Also easy to remedy if it does, you just slap another battery on in parallel to reduce the C rate. Winter cold / below-freezing overnights and mornings, is also easily solvable by insulating the battery and then throwing in a little PTC heater or two. We're talking 5W or 10W PTC heaters... really tiny. It doesn't take much to keep the batteries warm if they are in an insulated container. A bit of automation is always good here to only turn on the PTC heater when it gets too cold, and to turn on a small ventilation fan when it gets too hot (if that winds up being an issue). Also avoid connecting the heaters directly to the batteries, you never want to be in a situation where a battery is drained all the way to BMS-shutdown. The simplest solution is to have two little heaters, one that runs directly off of one of the DC solar strings for morning recovery "just in case", and another that runs off of AC. 5W each. Inverter fan noise is often annoying no matter what one does. But cleaning up the noise everywhere else is easy. Most charge controllers... well, certainly Victron's, have a temperature sensor input that allows a temp sensor to be slapped onto the battery and can be programmed to not try to charge the battery if it is too cold. This is very important if cold conditions are possible and the battery does not have an internal low-temp charging shutdown feature (most don't), because it doesn't take much to destroy the battery if you try to charge it in very cold temps. Fully automating this stuff adds complexity but is incredibly convenient. -Matt

WATER should be 1st but you most likely need solar to get it where you need it!

the reason people say "size higher than you need" is deeper than that. for example, you can't just "add more" to an existing array. HOW you wire things needs to change, which means you may end up having to retool, completely disassemble, or rebuild the entire array if you don't start big. there is also a MAXIMUM voltage and amperage that a charge controller/inverter can handle. the other reason is, even if you get 800W of solar panels, you WON'T be pulling 800W, except when the sun is hitting them DIRECTLY, which it is maybe 10% of the day. if you plan for MORE than you need, it won't be a major concern on the rare days when it's cloudy, too.

Some good point. Thanks.

Usually12v = 1000w of max solar input, 24v = 2000w solar input, 48v = 4000-8000w solar input. 24v batteries w/BMS used are cheaper than 12v. 48V can usually support 3000-13000w pure sine out continuous. (25-106Amps) with 1-2 parallel units. A mini split can do heating and cooling very well. I no longer needed a propane heater or stove or tank after getting enough solar. The next big thing is to figure out how to create 2.5-20+ gallons of potable water, per day, during sunlight, without drilling a well (atmospheric water generation) in the 115F hot desert, without putting much load on battery at all. I'm thinking centrifugal compressor or dehumidifiers in parallel during day time.

@@offgridsolitude Not a bad setup for 12v, but you will want to run continuous loads at times in the future, like a minisplit with a fridge/freezer or combined with an electric cooker or air fryer or kettle. Might as well plan a second system to power at least a cabin or RV (24-48v). You can buy used but really good 250w monocrystalline panels, ideally SunPower at SanTan Solar (Gilbert/Mesa) for $70-$80 a piece. Cheaper 250w panels are about $50. I personally found 2kw solar can power laptop, 12k minisplit, air fryer, kettle, heat pump, fridge freezer, music, cell phone on **almost all days in Arizona / California desert. I want 3-4kw solar for the cloudy days or high-energy usage days. 100w = ~400w solar storage per day. ~800w = 800x4= ~3200w give or take on average days. If you are gonna off-grid full-time, plan to use 8-12kw+ unless you want to be very frugal with power (meaning turning it on and off, which sucks). Use Batteryhookup website for LifePO4 batteries too. Hope this helps you save a few hundred in the future.

At this time I’m gathering information and ideas, I want to be off the power grid. New Year’s Eve 2021, the power company shut off the power at 11 pm and didn’t turn it back on for a few days, because of a fire in Boulder Colorado, that burned 500 homes. It was -40 and people and water pipes in their homes & businesses froze. Hospitals used emergency generators. I have to stay busy or the situation would drive me crazy. 😂😂
