Solar Power Wire Size Calculator

Cable sizes are particularly important for low voltage battery cables solar panels wind turbines and load cables.

Solar power wire size calculator. This online cable size calculator tool makes it easy to establish the correct size of cables for any dc power system. This is a very general system size estimation. The cable should withstand maxumum current in a always choose cable type that satisfied both conditions. Product list and cost of components.

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. Step 1 the first step is to decide on the voltage for your system. 12 24 or 48 volts. The solar cable gauge calculator is designed to provide estimates for wire gauge size to determine your need for cables.

I have 2 175 watts solar panels and 2 100 amp batteries. You also explained that the wire size depends on the current and the distance. The main issue is the wire size needed for the usually fairly long run to the solar panels. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142.

Other factors such as peak load shade location available panel space and seasonal use need to be taken into account. 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. Simply stated the higher the voltage the smaller the wire size that is needed to carry the current.

I wanted to make sure i got this right. Determine the size gauge of wire and cable to use in any part of your renewable energy system. To calculate wire size just enter. 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.

Use this to determine the right cable for your solar panels be safe and save money. 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. Diy wiring diagrams for 100w 200w 300w 400w 600w 800w kits. We want to help you get the system that s right for you.
