Solar Power Wire Size Calculator
Simply stated the higher the voltage the smaller the wire size that is needed to carry the current.
Solar power wire size calculator. The cable should withstand maxumum current in a always choose cable type that satisfied both conditions. 12 24 or 48 volts. Cable wire size needed in mm2 cross sectional area wire diameter in inches. This solar wire size calculator calculates the wire size of copper wire taking into account electrical parameters of the solar array or another device power voltage and current and cable s temperature working conditions as well.
The wire between the solar panels and between the solar panels and charge controller are smaller in diameter than the wires between the batteries and the batteries. Calculated wire diameter in inches or cable wire size in mm2 and rated maximum ampers for power transmission if cables are wired in a bundle or maximum amps for chassis wiring if each wire is routed separately. Detailed instructions for using the wire size calculator. This online cable size calculator tool makes it easy to establish the correct size of cables for any dc power system.
We want to help you get the system that s right for you. This solar panel wiring size calculator lets you to work out the gauge of wire to safely take the solar dc power from a set of solar panels. The solar cable gauge calculator is designed to provide estimates for wire gauge size to determine your need for cables. Cable sizes are particularly important for low voltage battery cables solar panels wind turbines and load cables.
The solar sizing calculator will then be able to tell you the minimum and recommended system size as well as the recommended battery output. Solar calculator for rv or camper van conversions. You also explained that the wire size depends on the current and the distance. Quickly calculate what gauge wire or cable you should use for your solar or wind power system based upon dc voltage current and wire run length.
I have 2 175 watts solar panels and 2 100 amp batteries. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142. Diy wiring diagrams for 100w 200w 300w 400w 600w 800w kits. Other factors such as peak load shade location available panel space and seasonal use need to be taken into account.
Step 1 the first step is to decide on the voltage for your system. I wanted to make sure i got this right. To calculate wire size just enter. The main issue is the wire size needed for the usually fairly long run to the solar panels.
Use this to determine the right cable for your solar panels be safe and save money.
