A Complete Guide How To Build A 5000 Watt Solar Generator

Nowadays, many more people want to use clean energy to fulfill their daily needs. Clean energy like solar energy is good for the environment. Because of that, you may want to build your own solar generator. But it can be hard if you don’t know how to start. We will show you the methods to build a 5000-watt solar generator via this article. Stay tuned and find out.

How to build a 5000-watt solar generator

  • Step 1: Gather your components and tools.

  • Step 2: Calculate the energy you need as well as test all the components.

  • Step 3: Build your case.

  • Step 4: Connect all the external parts.

  • Step 5: Test the solar generator.

  • Step 6: Use the solar generator.

You don't need a lot of specialized tools or supplies to make your own solar generator. These items are generally present in your workstation. They are also very available at your local hardware shop if you don't have them.

Once you've gathered your ingredients. There are only a few steps left to take to build your solar generator. Let’s take a closer look at these steps.

Step 1: Gather your components and tools

  • Rugged case

The first thing you need to have is a rugged case. If you have this, it can help to protect your solar generator. Also, it helps to bring and move your generator everywhere you want.

This rugged case should be highly robust and durable. You should test to see if it’s completely waterproof. Besides, it should be able to protect your generator in harsh weather. You won’t want the generator to be damaged from the outside.

  • Solar pan

Solar panel for generator

These are the most crucial components of any DIY solar generator. These solar panels are in charge of receiving sunlight. And these panels will turn them into heat and energy.

Because you'll be building a solar generator from scratch. Your solar panels must be the focal point of the entire setup. You must also verify that these solar panels are long-lasting and can sustain heavy use.

Because you'll be exposing them most of the time. You should look for solar panels that can withstand rigorous handling. Also, you should test it for harsh conditions.

  • Battery

Battery for generator

This is the second most crucial part of your DIY solar generator. These are important because solar panels absorb energy from many sources. And then store it in the battery.

The battery is in charge of you using this energy in many manners. Yet, selecting the right type of battery may be tricky. There is a good piece of advice is to consider what you intend to use your solar generator for.

Lighter and heavier usage may need different batteries, so bear this in mind! In general, lithium-ion batteries are best suited for use in solar generators.

  • Charge controller

The charge controller in your solar generator may have a significant impact on its performance. Charge controllers govern the number of energy levels coming from your solar panels to your battery. You should have a steady flow so that your battery is not under-or over-charged.

Either of these circumstances may state that your solar generator is not operating at peak efficiency. You may go without a charge controller - although we advised that you do so to be safe.

If you don't have a charge controller when you need it, your battery will deplete faster than you'd want.

  • Solar-powered inverter

This is a necessary component of building your own solar generator. Because the solar panels collect energy and store it in the battery. This energy cannot be used.

Invest in a solar-powered inverter that protects your system from overload. And it will have a larger conversion capacity.

  • 12V DC meter

This is a critical component in constructing your own solar generator. Because the solar panels gather and store energy in the battery.

Invest in a solar-powered inverter with a higher conversion capacity. It will protect your system from overload.

  • Battery maintainer

Consider investing in a battery maintainer to better care for your battery. And guarantee that it does not wear out in a short amount of time. As the name implies, the battery is in charge of looking after your battery while it is not in use.

When you don’t use your battery for an extended period of time. The battery maintainer transfers tiny quantities of energy to it. To keep it operating and functioning even when it is dormant.

Step 2: Calculate the energy you need as well as test all the components

It's time to start attempting to put your DIY solar generator together. It is critical to note that different appliances demand varying amounts of energy. Thus it is advisable to confer with whatever appliance you will be putting into the battery of your solar generator to power them up.

Most appliances must have low energy points. But others, such as toaster ovens, coffee makers, and refrigerators. They may demand higher energy sources (anywhere from 1000W to 1200W).

When it comes to solar generator testing. There are three key components that you must ensure. This includes your solar panels and charge controllers. As well as your inverter and battery maintainer.

To test your panels and charge controllers, try connecting each one to the battery. Connect them to the (+) and (-) sockets. And wait for the battery to light up green to say that it is truly powered.

Repeat the process with the solar panels. But this time position them in a sunny location where they can absorb energy. Keep testing the other components to see if they’re doing well.

Step 3: Build your case

How solar generator works

To begin, place the battery inside the case and arrange it such that the 12V DC meter you have is available to you. This will come in handy if you need to rapidly check the voltage.

At this stage, you should also double-check the outlets of the other components. You'll attach them to the solar generator. You must arrange your appliance outlets, plugs. And other similar items so that they do not interfere with one another.

You should give no extra consideration to outlets with big backings. If any of your appliances have big backings. You must see the spatial features of the inside of your tough case.

Once you've completed this. It's time to drill several holes and connect the DC meter and outlets.

Step 4: Connect all the external parts

The first thing you'll want to do is connect your 12V DC meter to your battery's terminals. Make sure you attach it in such a manner that you can clearly see the voltage at all times.

After that, connect your outlets to the batteries as well. Secure them carefully so that they are well attached.

Finally, you must attach the most essential component — the solar panels. You may either connect your solar panels with the aid of plugs. It can link your panels to your batteries.

Or you can select the more long-lasting option of connecting them as you did with your other components. When you have completed this step. Your solar generator will be ready to use.

Step 5: Test the solar generator

So, how can you know whether the solar generator you built for yourself works? There is only one way to find the output of your solar panels in the sun and test your solar generator.

If the cords connecting your panel and battery are too lengthy. You might try putting only your solar panels in an area that receives a lot of sunshine.

In this manner, you can determine whether your solar generator is completely operational.

When your solar panels have received enough electricity. You may check the voltage on your DC meter. Allow your solar panels to charge your battery entirely by leaving them out in the sun.

Step 6: Use the solar generator

You may now start using your solar power generator to its full potential. Now that you've tested it and ensured it's completely functional!

Essentially, at this point, you must connect any items you need to charge to the charged-up battery. Once the battery has charged. You can unplug it from the solar panels.

Connect your appliances to the outlet in your solar power generator. And you may start using it right away.

For the first few usages, you will need to check how long it takes to charge each item. So that you can have a general sense of the charging times.
