GridCalc Pro

GridCalc Pro is an offline electrical calculation workspace for engineers, electricians, designers, and commissioning teams. Calculate and review: • EV charging feeder comparisons and cable screening using your sourced conductor parameters • Three-phase power, current, and voltage • Voltage drop with AWG, kcmil, or mm² conductor input • Transformer load and capacity conversions • CT and PT nameplate ratios with safety warnings • Power-factor correction • Electrical and engineering unit conversions • PV string/inverter and battery/PCS nameplate pre-checks Built for work that must be revisited: • See formulas, intermediate steps, assumptions, and warnings • Save calculations to favorites, history, and projects • Search saved work by title, project, values, source, warning, or formula context • Restore the original inputs instead of keeping only a final number • Export calculation context…
