How Much Energy Do You Need
To understand the amount of energy you require, you will first have to figure out the source for which you will use the solar power generator. Most people use it for their homes, so you can look into your electricity bill to get a rough idea, or you can refer to the chart here to note the major ones
- Fridge 1200W to 1500W
- Toaster 1200W
- Fan 10W to 50W
- Cable box 35W
These are the equipment that requires the most energy. Using this list, you can now curate a rough idea of how much energy you want to draw from the grid and then create the requisite ingredient requirement.
Key Factors When Shopping For A Solar Generator
Solar generators come in different sizes and shapes, so picking one that will address your personal needs should be your priority. Choosing a solar generator can be challenging, especially when you are presented with different options, so we created this shopping list as a good starting point.
Since not all portable solar backup power generators are the same, people need to know what the generator can and cannot do. Knowing how you intend to use your generator should help guide you to the right solution.
Some of the top brands to compare include Jackery, Goal Zero Yeti, Bluetti, EcoFlow, Point Zero Energy, Renogy, and Tacklife. Each company makes its products unique, so a closer look at what each one offers can help you make a sound decision.
Diy Solar Generator Step : The Battery
First, as in any off-grid solar system, the battery is chosen to store the solar energy. The battery that is included in the EcoFlow Delta is rated to hold about 1300Wh of energy, so a comparable standalone battery would be the Lion Energy UT 1300. Although the Lion is a great solar battery, it retails for around $900, which means that there is only roughly $500 left to spend on other parts of the system before it is equal to the price of the Delta. With the Lion UT, users lose the Deltas rapid AC charging capability as well.

Things To Keep In Mind If You Use A Custom
If you have enough experience in DIY electronics, you can make a custom lithium battery to use with your system. There are several things to keep in mind:
Low-Temperature Cut-off or Heating System Lithium batteries cant be charged under 32°F without suffering permanent damage. If you use a lithium battery, find a solar charging controller with low-temperature cut-off.
MPPT Charge Controller Capable of Charge Profile Editing Each battery needs a different max voltage. Program the MPPT charge profile parameters for the exact type of battery you plan to use.
A DIY solar generator is a self-contained and portable mini-power plant that can allow you to be 100% independent from the grid.
Over-Discharge Protection System If you over-discharge a lithium battery, youll change its chemistry and damage it permanently.
High-Temperature Protection If you plan to use the battery in a high-temperature environment, youll need a battery cooling system.
Cell Balancing If you regularly charge and discharge from 100% to 0%, your cells will fall out of balance, so you need to use a manual RC battery cell balancer.
Potting batteries Lithium batteries contract and expand during discharge and charge. So unless you compensate this with a foam pad, you shouldn’t pot them.
Mounting The External Components
Mounting the external components of this DIY solar generator is more challenging than the internal parts. For the most part, they will require you to either cut large holes or make cut-outs in the case walls that can be tricky. This is where a comprehensive hole saw set, and the Dremel tool will be invaluable. Here is a quick tip for using a jigsaw to cut regularly shaped holes. You can also use a hand fretsaw or even a hacksaw blade to make cut-outs similarly.
Here are schematic layouts of the positions of all the external components for reference.
NOTE: With most flush surface mount components, the device has a flange footprint and a cut-out footprint. The cut-out footprint refers to the outline of the component that physically goes through the case wall. As a reference for all the external surface mount components in this build, here is an example.
NB: For each of the components we will mount going forward, youll be marking the case for the cut-out dimensions.
Mounting the Inverter Remote On/off Switch
This switch is labeled as B in the top side component diagram above and is located on the left-hand side of the handle side of the case. To mount the switch, measure the cut-out profile and mark it on the case in the position indicated. Using a jigsaw or hand saw, cut out the marked outline and check that the switch fits through the hole snuggly but freely.

Table Solar Panels Watts And Dimensions Compared
There are only two real options seperate flexible solar panels or a folding type of flexible such as those supplied by Dokio.
I use 100 watt flexibles for most applications, from pergola mounting to running a trolling motor on my inflatable canoe. The big thing is that they are about 5 times lighter than standard fixed solar panels.
On the downside, they tend not to last as long. I make a custom frame for them out of aluminium angle, which helps keep them rigid without adding too much extra weight.

Prep The Outside Of The Box
With your battery box or camera case in hand, you will want to figure out where you want the DC meter and outlets to be laid out. There are a few things you want to take into consideration when doing this part.
First, you will want to consider how you want the battery box to sit when it is being used. Layout your DC meter in an easy to read place so that you can access it at any time to get a quick reading.
When installing your outlets, take into account how your chargers, plugs, and other appliance accessories will layout next to each other. For example, if a commonly used appliance has a larger plug, it may be beneficial to separate it from other close outlets.
Second, you will need to take into account how everything will mount inside of your box. If the outlets have a large backing, you will need to make sure they will fit once you get your inverter and battery into the box.
Once you have determined all of the above and made sure everything will work without interfering with each other, you can start to carefully drill and install your outlets and DC meter.
How To Connect The Solar Power Generator
To start with, the solar panel ought to be associated with the charge regulator then this charge regulator ought to be associated with the battery preferably a profound cycle battery. This battery should be associated with the inverter, and the inverter should be associated with the appliances youre utilizing.
Its up to you where you acquire all these parts you could go to your local hardware store or discover somebody whos parting with them or selling them for cheap. Or then again, you could attempt to create your own solar panel it isnt so hard if you have all the parts, but it does require some time.
If you want to add significantly more to your arrangement, you can do that. The main thing youll want to put resources into is a battery box this will keep your batteries safe and shielded from an external perspective and is essential if you have pets or kids.
You may also want to get a system meter, which discloses to you how full your battery is and how much power is being drawn at any given second which can help distinguish and forestall issues.
The charge regulator restricts how much power is drawn from the battery and greatly broadens its life you dont absolutely require it, but it will save you a ton of cash over the long haul because your batteries last any longer.

Dirty Little Secret#: Leading Portable Solar Generator Vendors Use Sneaky Language
Buying a solar generator should be about facts you can express with numbers, not the kind of hyped sales language thats commonly offered these days. All you really need to know to make an informed buying decision about a particular unit comes down to the answers to five simple questions:
But the reality of solar generator marketing these days is long on emotions and short on clear technical details. One of the highest profile solar generator marketers right now is using a slippery,1500 word snake oil pitch that includes dishonest phrases such as:
Thats just silly. No matter how good a solar generator is, its dishonest to call it a true breakthrough. All the technology behind a solar generator has been around for decades. You could have built one in 1983 if you knew how.
Really? 1800 watts can hardly be described as maximum power. And minimum time? What does that mean when it takes most ready-made solar generators at 10x to 15x as long to recharge as it does to discharge?
