Installation Components

On this page, we’ve done our best to gather all of the components and tools you’ll need to build your own Solar Power System. We’ll be adding to this page over time, so if there is something you think should be on this list, please comment below and we’ll add it in.

Cables – Wiring – Accessories

Each type of wire serves a unique purpose in the overall functionality of a solar power system, the following wire selection should cover all of your needs.

Battery and Inverter Cables

These large gauge wires are suitable for Battery Banks, Power Inverters, and other large current loads. If you need help determining which size wire to use, visit our Wire Selection Guide.

Small Gauge Wire and Cables

These wires are for smaller amperage loads. Use these to distribute power to sockets, lights, fans, etc..

Solar Cables

Solar cables go from the solar array (solar panels) to the charge controller. They are specifically designed to stand up to harsh outdoor conditions.

Cable Lugs

Purchase only high quality lugs as the difference in price is minimal, but the difference in performance can be substantial. Crimping tools are further down on this page.

AC Wiring and Supplies

Triplex wiring for AC components, 120V outlets, and power strips.

Fuses and Breakers

Fuses and breakers prevent over current conditions that can lead to fires in electrical systems. Without them, the system can become hazardous. Proper selection and installation is crucial for maintaining the safety and reliability of a solar power system. Read our Guide to Fuse Sizing if you need help in this department.

ANL Fuses

ANL fuses have a see-through window to see if they’ve blown and they are ignition protected for safe use in sealed compartments that can contain flammable vapors.

Mega Fuses

Mega fuses do not have a see-through window so you’ll need to use a multimeter to verify if they’ve blown. Additionally, mega fuses are not ignition protected so they cannot be used in sealed compartments with flammable vapors.

Circuit Breakers

Circuit Breakers can be more convenient than fuses because you’re able to reset them if they trip.

Be careful however because DC Circuit breakers have been known to cause fires. Only use breakers from high-quality manufacturers like Blue Sea Systems and Bussmann.

Blue Sea Systems Breakers

Blade Fuses

For circuits under 30A, use a blade fuse holder and quality blade fuses.

Tools for Building Solar Systems

To properly install a solar power system, you’ll need more than just the components and wiring. An assortment of cutters, crimpers, strippers, and basic hand tools are essential for screwing things together and making the necessary connections.

Crimping Tools

Use cable and wire crimpers for attaching lugs and terminals to wires.

Wire Stripping Tools

Wire strippers safely remove the wire insulation without damaging the wire underneath.

Cable Cutters

Quality cable cutters use leverage to make cutting wire and cable easy.

Testing Tools

These tools are useful for verifying polarity, testing, and diagnosing potential problems. They’re not 100% necessary since you can technically build a system without them. However I believe that anyone working with electricity should own atleast a multimeter and know how to use it.

Terminals and Cable Management

Busbars, terminals and cable management supplies help keep your system tidy. By utilizing these tools, you can create a neat and efficient system that is easy to maintain and troubleshoot.


Busbars allow clean power distribution throughout your electrical system, without them your system will get messy very quickly.

Cable Management

Cable management is important not only for looks, but also for safety. Since you’re probably building your system in an RV or Boat, it’s best to secure your wires every 12 inches or so. Unsecured wires can come loose and become a short circuit/fire hazard.


Accessories like USB sockets and LED lights help complete your solar project. Below you’ll find some of the products we personally find most helpful.

12 Volt Outlets and Sockets

The following 12 Volt sockets should cover the majority of user needs.
