![]() Refer to our guide for more info on wiring your solar installation. ![]() Then, an equal string needs to be created and paralleled. Wiring MC4 Equipped Modules in Series: If you have two or more solar modules to wire in series, the MC4 connectors make it very simple. ![]() For this connection, a string is created by 2 or more panels in series. That’s when series-parallel connections are used. Sometimes in larger systems we have to get creative to stay within certain amperages and voltages accepted by charge controllers while still producing enough energy. Series connections also yield less voltage drops during a charge cycle, which typically creates the most efficient solar panel charge time.

The benefit of series is that it is easy to transfer over long distances. Renogy MPPT controllers can accept 100 volts input. MPPT Controllers are able to accept a higher voltage input, and they will still be able to charge your batteries. Series connections are mostly utilized in smaller systems with a MPPT Controller. The downside to parallel systems is that high amperage is difficult to travel long distances without using very thick wires. Our dream was to pull into a site, pull out our portable solar cells, set them up in a sunny location, plug. A benefit of wiring in parallel is that if one solar panel experiences a failure, the other solar panels will continue to produce power. Adding a portable solar cell system is the solution. Parallel connections are mostly utilized in smaller, more basic systems, and usually with PWM Controllers. When wiring solar panels in a series, the voltage is additive, but the amperage remains the same. When wiring solar panels in parallel, the amperage is additive, but the voltage remains the same. When deciding how to wire your solar panels, there are a few factors to consider. Should I wire my solar panels in series, parallel, or series-parallel?.If your wire is rated at less amps than your system produces, your wire will most likely heat up and could even catch fire or cause damage to your solar system. It’s actually better to go a little higher just to make sure the wires can handle all the current. If your system produces 7 amps, you need 7 amp wire. The higher the amps of your system, the thicker your wire has to be. Wires used in solar installations are rated based on their amps. ![]() If you select wire that is too small, your battery bank may not charge fully or your system may not run well. Selecting the right sized wire is crucial to making sure your solar installation operates properly. ![]()
