The main rating of a solar charge controller that you should consider is its Output Current rating. The Output Current rating or the “size” of the solar charge controller that you need for your 300w solar panel, will mainly depend on 3 factors: The voltage of your battery…
The size of wire that you need to connect your solar components together will generally depend on 2 variables: The maximum amount of current (Amps) that will be flowing through the wire The length of the wire In this article, you’ll learn how these variables come into play,…
In this article, I explain how to correctly size the wires that you need to connect your solar panels to your charge controller. After reading this, you’ll learn about wire size and ampacity, wire insulation, electrical codes for sizing these wires, temperature correction factors, etc…To make this guide…
In this article, I explain the difference between wiring solar panels in series and wiring them in parallel. You’ll learn about voltage, current, and power in both configurations, and you’ll also learn how series, parallel, and series-parallel connections are achieved. Solar panel series vs parallel: What is the…
Fuse and other overcurrent protection devices are an essential part of any electrical circuit. In this article, I’ll explain why you need fuses between your solar panels and the solar charge controller, and I’ll show you how to correctly size these fuses. Do you need fuse between solar…
Assuming you want to charge the battery on a daily basis, there are a couple of factors that determine the amount of solar power needed to charge a 100Ah battery: The amount of energy (in Watt-hours) that you take out of the battery on a daily basis. The…
There are a few factors that determine how long it would take to charge a 100Ah battery with a 200W solar panel. In this article, I thoroughly explain these factors, and I provide a few steps that you can take to get as much of an accurate estimate…
A 7kW rating on a solar system means that the system is potentially capable of producing 7 kilowatts (7000 watts) of power at a given moment. But this amount of power production is not guaranteed and would require a certain amount of sunlight to happen. In other words,…
With the right weather and enough sunlight, at a given moment, a 10kW solar system is capable of producing 10 kilowatts, which is a substantial amount of power. However, what you pay for at the end of the month, and what really matters, is not Power (kW), but…
A 12kW solar system is a relatively large system and would produce a relatively high amount of energy. However, the exact amount of energy that a 12kW solar system produces would depend on the amount of sunlight that it receives. The amount of sunlight that a solar panel…
