Step by Step Installation Process

Step 1

It turns out to be a straightforward installation process. Just cut two sections to the desired length to strip the wire and strip them on both ends. 

Make sure the fuse is in the holder. To determine the proper fuse size, please use our online calculator. 

Using a wire connector of your choosing, attach one of the fuse holder’s wire leads to the shorter battery cable you have chosen. Connectors should be shrink-wrapped using a hot air gun and heat shrink tubing. 

Step 2

Connect the charge controller to the battery as per the instructions in the documentation provided by your charge controller. 

Connecting the “+” battery terminal to the positive thinking requires a cable, which has a fuse. Using a Renogy charge controller, connect the battery wires to the voltage regulator first. Connect the negative cable to the battery first, then the positive cable. 

Your battery charger should signal that the battery is correctly connected by turning on or lighting up. For example, a light turns on in mine. The charge controller programming instructions in your handbook may direct you in this direction.

Step 3

A pre-attached MC4 connection is included with the majority of solar panel cables. Solar adapter cables may be used to connect solar panels to a charge controller. Attach the MC4 inline fuses, positive extension cable, and MC4 adapter cable to the panel’s positive cable.

If you use a negative extension cable, attach that first, followed by the MC4 adapter cable. Keep your fingers away from the exposed wires!

Step 4

Using my $11 Pvc solar array mount, you can easily place your solar array in direct sunshine at the optimal tilt angle in your region. Your battery charger should show that the batteries are charging after you have done so. 

During regular charging, a light on my device flashes. Let the solar panel do all the work for you. Once the battery is fully charged, the battery charger will turn off the charger.

Solar Panels Series Or Parallel Connection?

If you are a homeowner learning about solar energy alternatives for the first time, it’s easy to get lost in all the jargon. Solar panels may be connected in many different ways, which you may have seen before. Is this very important to you? After all, all you care about is how much power the solar panel series or parallel generate!

Your solar panels’ wiring is essential. It affects your system’s performance and the inverter you may utilize. You will want your solar panels to be correctly connected to get the most bangs for your buck.

What Would It Mean To Connect Solar Panels In A Chain?

Solar panels feature two positive and just one negative terminal, much like a battery.

Series connections may be made by connecting the positive and negative terminals of two separate panels. A Conveys circuit is formed when two or more panels are connected. 

If more than one solar panel is connected in series, the total voltage increases, but the total amperage does not change. The series voltage would be 80 volts, and the amperage would stay at five amps if two 40 volt solar cells with a 5 amp rated amperage were connected in series.

The voltage of an array may be increased by connecting panels in series. The inverter in a solar PV system must run at a specific voltage to be effective.

Your inverter’s operational voltage window requires series-connected solar panels, so you do just that.

What Does The Term “Parallel Wiring” Refer To?

It is common for solar panels to be wired in parallel, in which the positive end of one panel is linked to another’s, and their negative terminals are connected.

A combiner box has a positive connection for the positive wires and a negative connector for the negative wires. A PV generation circuit is called when many solar panels are connected in series. 

Parallel solar panel wiring increases current while voltage stays constant. Because the voltage would stay at 40 volts if you connected two panels in parallel, the amperage would climb to 10 amps.

Your inverter’s operational voltage restrictions may be exceeded by connecting multiple solar panels in parallel. There are amperage limits on inverters, which may be overcome by connecting your photovoltaic power in series.

The Series And Parallel Connection Of Solar Panels With Pros And Cons –

  • The cost of electricity is significantly reduced or perhaps eliminated when using solar power.
  • A house with solar panels has a higher resale value.
  • Reduce your carbon footprint by going solar.
  • Rising energy expenses are something that the solar system guards against.
  • You may recoup some of the money you invested in solar power.
  • Solar power may be used in a variety of ways.
  • The grid can recoup some of the cost of solar power.

Cons –

  • Not all types of roofs are suitable for solar power.
  • There are certain drawbacks to this if you plan on moving soon
  • Reduced savings due to lower electric bills
  • The initial outlay may be prohibitive.
  • It might be challenging to find a good installer.

Instead Of Choosing Between Series And Parallel, Why Not Do Both?

Generally, connecting in series raises voltage, whereas connecting in parallel increases current. An inverter right for you will depend on voltage and amperage, so keep that in mind while planning your system.

Series/parallel connections are the most common configurations used by solar installers. As a result, your solar panels can perform to their full potential since the system can handle larger voltages and amps without damaging the inverter.

How To Install The Renogy Solar Panels?

Scaffolding Should Be Erected

To begin, you will need to create scaffolding on the roof to secure your safety throughout the installation procedure.

Add Mounts For The Solar Panels

After that, it’s time to put together the solar array mounting system. This will support the solar panel base. To get the most sunlight, the whole construction. Today must be slanted at an angle ranging from 18 to 36 degrees.

To Begin, Set Up The Solar Array

After the mounts are in place, the solar panel must be attached to the mounting framework. All the bolts & nuts should be tightened to secure the structure.

The Solar Panels Should Be Wired Up

Putting in the electrical wiring is the next stage in getting the job done. All solar panels may be connected using MC4 connections. Hence, they are the most common solar panel connector. To prevent damage to the home’s electrical system, turn off the power before beginning the wiring project.

How To Connect The Renogy Solar Panels?

Build A Solar Power System

Putting together, a solar power system starts with acquiring the essentials. Solar panels, a charge controller, an inverter, as well as a battery bank are the four main components you will need. 

Additionally, you will need to purchase a breakaway switch and other electrical components such as an MC4 connection and fuses. Always remember to read the instructions that come with the solar panel module.

Make Sure That The Inverter Is Working Correctly

Power generated by solar panels (DC) is used by electrical equipment that needs AC power (AC). Using an inverter instead of an adapter may be a lifesaver while traveling. Inverters may be the square wave, modified sine-wave, or pure sine-wave inverters, depending on the wattage and inverter. 

The output of a modified sine wave is not acceptable for specific appliances, such as a refrigerator, whereas square waves are not. Your solar system will benefit significantly from a power inverter.

If your are looking to connect your solar panels to an existing solar inverter, then read this article for more information.

Use A Battery Bank To Charge The Solar Panels

Batteries and solar panels must be connected. If you have a PV system with these features, you don’t have to perform any more work. Make series and parallel links if you’re not provided a single unit. 

A series connection may be made by connecting a device’s positive and negative terminals. It would help if you connected one device’s negative terminal to another to make a parallel connection.
