Using wire that is of insufficient diameter between your solar panels and solar regulator can cause excess heat generation. This is not only wasted electricity (also known as line loss), but is a fire hazard. Undersized cable used between the deep cycle battery and your appliances can cause symptoms such as lights dimming and unexpected equipment shutdowns.
It's incredibly important not to skimp on your wiring in your solar energy system. If you buy undersized or poor quality wiring, you'll likely be replacing it very soon; so cheap wire can actually cost you more in the long run.
If you're not sure what wire size you need, try our DC cable sizing calculator - based on your input of how many amps will be running over what distance, the calculator will provide you with a guide in mm2, which is a cross-sectional measurement and the sizing we use for cabling available in our online store. Note that this is a very different measurement to standard millimetre diameter. If you need to convert from that standard to another standard such as AWG, inch or millimetre diameter, you can use the conversion chart below.
|MM2||MM diameter||AWG||Inch Diameter|
