VoltDrop is a field-ready electrical calculator engineered for solar installers, RV builders, marine mechanics, and electricians. Calculate circuit voltage loss and determine recommended wire gauges instantly without requiring an internet connection. Whether sizing 12V battery banks, 24V solar arrays, 120V household runs, or 240V heavy machinery lines, VoltDrop provides precise conductor sizing to keep your electrical systems safe and efficient. Key Features: • Instant Voltage Drop Calculation: Enter voltage, current, one-way or round-trip distance, and allowable drop percentage to calculate conductor resistance and voltage loss. • Wire Gauge Sizer: Get recommended American Wire Gauge (AWG) and metric millimeter sizes for both copper and aluminum conductors. • Multi-Voltage Support: Preconfigured presets for low-voltage DC applications (12V, 24V, 48V) and AC branch circuits (120V, 208V, 240V, 480V). • Conductor Material Selection: Compare copper and aluminum conductors side by side to evaluate cost, weight, and conductivity trade-offs. • 100% Offline Functionality: Designed for crawlspaces, engine bays, remote off-grid cabins, and marine vessels where cellular coverage is unavailable. • Distraction-Free Workspace: Clean interface with no full-screen interruptions, no forced account creation, and zero analytics tracking. Built for professionals and serious DIY builders seeking reliable electrical formulas in demanding field conditions.
