Wire Sizing Tool for 1. Volt DC Systems. Handy tool for sizing wires and cables for 1. Volt Systems. Also see the Easier to Use Wire Sizing Calculator. Properly sized wire can make the difference between inadequate and full charging of a battery system, between dim and bright lights, and between feeble and full performance of tools and appliances. Designers of low voltage power circuits are often unaware of the implications of voltage drop and wire size. In conventional home electrical systems 1. The overriding concern is fire safety. In low voltage systems 1. VDC the overriding concern is power loss. Wire must not be sized merely for the ampacity, because there is less tolerance for voltage drop except for very short runs. For example, a 1. V drop from 1. 2V causes 1. V drop from 1. 20. V. Universal Wire Sizing Chart.

A general rule is to size the wire for approximately 2 or 3 drop at typical load. When that turns out to be very expensive, consider some of the following advice. Different electrical circuits have different tolerances for voltage drop. LIGHTING CIRCUITS, INCANDESCENT AND QUARTZ HALOGEN QH Dont cheat on theseA 5 voltage drop causes an approximate 1. This is because the bulb not only receives less power, but the cooler filament drops from white hot towards red hot, emitting much less visible light. LIGHTING CIRCUITS, FLUORESCENT Voltage drop causes a nearly proportional drop in light output. Flourescents use 12 to 13 the current of incandescent or QH bulbs for the same light output, so they can use smaller wire. We advocate use of quality fluorescent lights. Buzz, flicker and poor color rendition are eliminated in most of todays compact fluorescents, electronic ballasts and warm or full spectrum tubes. DC MOTORS may be used in renewable energy systems, especially for water pumps. They operate at 1. AC motors, and eliminate the costs and losses associated with inverters. DC motors do NOT have excessive power surge demands when starting, unlike AC induction motors. Voltage drop during the starting surge simply results in a soft start. AC INDUCTION MOTORS are commonly found in large power tools, appliances and well pumps. They exhibit very high surge demands when starting. Significant voltage drop in these circuits may cause failure to start and possible motor damage. Follow the National Electrical Code. In the case of a well pump, follow the manufacturers instructions. PV DIRECT SOLAR WATER PUMP circuits should be sized not for the nominal voltage ie. V but for the actual working voltage in that case approximately 3. Dmss Software For Windows on this page. V. Without a battery to hold the voltage down, the working voltage will be around the peak power point voltage of the PV array. PV BATTERY CHARGING CIRCUITS are critical because voltage drop can cause a disproportionate loss of charge current. To charge a battery, a generating device must apply a higher voltage than already exists within the battery. Thats why most PV modules are made for 1. V peak power point. A voltage drop greater than 5 will reduce this necessary voltage difference, and can reduce charge current to the battery by a much greater percentage. Our general recommendation here is to size for a 2 3 voltage drop. If you think that the PV array may be expanded in the future, size the wire for future expansion. Your customer will appreciate that when it comes time to add to the array. WIND GENERATOR CIRCUITS At most locations, a wind generator produces its full rated current only during occasional windstorms or gusts. If wire sized for low loss is large and very expensive, you may consider sizing for a voltage drop as high as 1. That loss will only occur occasionally, when energy is most abundant. Consult the wind systems instruction manual. More techniques for cost reduction. ALUMINUM WIRE may be more economical than copper for some main lines. Power companies use it because it is cheaper than copper and lighter in weight, even though a larger size must be used. It is safe when installed to code with AL rated terminals. You may wish to consider it for long, expensive runs of 2 or larger. The cost difference fluctuates with the metals market. It is stiff and hard to bend, and not rated for submersible pumps. HIGH VOLTAGE PV MODULES Consider using higher voltage modules 1. BP 5. 85 and BP 5. In some cases of long distance, the increased module cost may be lower than the cost of larger wire. SOLAR TRACKING Use a solar tracker by Zomeworks so that a smaller array can be used, particularly in high summer use situations tracking gains the most energy in summer when the sun takes the longest arc through the sky. The smaller PV array will require smaller wire. WATER WELL PUMPS Consider a slow pumping, low power system with a storage tank to accumulate water. This reduces both wire and pipe sizes where long lifts or runs are involved. A PV array direct pumping system may eliminate a long wire run by using a separate PV array located close to the pump. The page pumps. htmlSun. Rise Submersible, Solar Slowpump, Flowlight Booster Pump and Solar Force Piston Pumppage are highly efficient DC pumps that are available up to 4. V. We also make AC versions and converters to allow use of AC transmitted over great distances. These pumps draw less running current, and far less starting current than conventional AC pumps, thus greatly reducing wire size requirements.
