Fuses and circuit breakers are what you call overcurrent protection devices (or OCPDs for short), and their job is to disconnect the circuit in case the current (in Amps) exceeds a certain threshold. This allows them to protect the wires and the equipment if – for any reason…
To find the proper wire and fuse (or circuit breaker) sizes for your 3000 Watt inverter, you’ll need to calculate the maximum amp draw of the inverter. This maximum amp draw will generally depend on 2 factors: The efficiency of your inverter. The lowest battery voltage at which…
The amount of current (Amps) that a 1500 Watt inverter draws will mainly depend on the voltage of the battery bank (12V, 24V, or 48V), and the power usage (Watts) of the AC load. However, the wires and over-current protection devices (fuses and circuit breakers) used for the…
The maximum amount of Current (Amps) that a 2000 watt inverter is capable of drawing from the battery will mainly depend on 2 factors: The conversion efficiency of the inverter The voltage rating of the battery bank And in order to size the wires and the fuse (or…
In this article, I discuss the amount of Current (Amps) that a 1000 Watt inverter is capable of pulling from the battery and explain how to use the voltage of your battery bank and the efficiency of your inverter to determine this amount of current. I also discuss…
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…
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…
Do I need a fuse between charge controller and battery? The answer is yes, you do need a fuse between your charge controller and battery bank. Should an overcurrent occur, you would want to have an overcurrent protection device (OCPD) placed between your charge controller and battery. An…
The size of the fuse that you use between your battery and inverter will depend on: The amount of current (Amps) that you’d like the inverter to be able to pull from the battery. The amount of current that the wire between your inverter and battery can safely…
