The Parts and Components You’ll Need To Make Your Own Solar Generator

Solar generators are basic devices that just need six key components to work properly.

#1. Solar Panels on Wheels

Your DIY solar generator kit would be incomplete without a solar panel.

It will convert sunlight into DC power (Direct Current).

Choose solar panels that are foldable or portable.

They offer a unique, small, and robust design that is ideal for outdoor use.

Please take note:

Price changes affect the components needed to make a DIY solar generator.

#3. Battery

A battery is required to use the electricity generated by your DIY solar generator at any time.

It will store solar energy and discharge it as needed.

Lead-acid and lithium-ion batteries are the two types of batteries available.

GEL and AGM are two different names for lead-acid batteries.

They are inexpensive to purchase and do not need any upkeep.

As a result, we strongly advise you to acquire a lithium battery instead.

When it comes to storing solar energy, Lithium-Ion batteries (also known as LiFePO4) are considerably better than GEL or AGM batteries.

Their initial cost is greater, but they outlast lead-acid technology in terms of longevity, dependability, and energy density (weight).

You will not be disappointed with your decision.

#4. Inverter (AC/DC)

Only DC power is provided by your portable solar panel and battery storage equipment.

Our household appliances, on the other hand, run on AC electricity (Alternative Current).

As a result, the inverter will switch from DC to AC (110V/220V, 60Hz).

For effective power conversion and a clean electrical supply, we suggest a pure sine wave inverter.

Step-by-Step Instructions for Building a DIY Solar Generator

To assemble your solar generator kit quickly and simply, follow these five steps.

To make a DIY solar generator, you’ll need the following items:

  • A hole saw and a drill
  • Driver for screws
  • Knife for everyday use
  • Cutter for wires
  • Tape for electrical connections
  • Adhesive gun
  • Sealant made of silicon

Step 1: Gather Evidence For Your Case

Because the solar generator is plug-and-play, you should be able to reach all of the outlets without having to open the casing.

With a hole saw, gently cut through the casing and install the outlet plug.

To seal it, apply silicon all around it.

A second hole is required to connect the solar panel to the solar charger.

We suggest utilizing silicon-sealed waterproof electrical connections.

Rep for additional external components such as the inverter remote control panel, led lights, and master switch using the same procedure.

Step 2: Put The Battery In

Because the battery is the most important component of your DIY solar generator kit, it should be installed first.

Although LiFePo4 batteries may be used in any location, we suggest putting them in a case corner.

A battery strap should be used to secure them to the case’s wall.

Step 3: Put the Solar Charge Controller in Place

The solar charge controller must be permanently attached to your case.

Make sure you have adequate room for the batteries and solar panels’ wiring.

Step 4: Connect the Inverter

The inverter, which is the second-largest component, may be mounted near the outlet on the wall.

Straps are recommended since they are easy to remove for maintenance.

Make sure there’s adequate room around the inverter for proper ventilation.

Step 5: Fuse and Wiring Installation

It’s time to connect your system now that all of your components are securely fitted in your case.

Connect the inverter to the outlet plug.

To connect the inverter to the battery and the battery to the solar charge controller, use 12 gauge wire (12 AWG).

Connect your solar panel’s extension cord to the solar charger (12 AWG).

Three fuses are required: one for the solar panel and the charge controller, one for the charge controller and the battery, and one for the battery and the inverter.

For appropriate wiring, refer to the figure below:
