À propos MDH Engineering
I build electrical design, software, and industrial optimisation work for mining and plant operations — and I publish free calculators so the same numbers are available on the job.
The tools on mdhengineering.com cover PV string voltage and current, three-phase load current, and LV cable sizing with SANS 10142-1 deratings for installation method, temperature, grouping, and spacing. They stay free.
A coffee keeps the hosting running and pays for the next calculator. If a string check, a kW-to-amps conversion, or a cable size saved you a few minutes, that’s what this page is for.
