- [PRO] Solar string dimensioning calculator. Determines the minimum voltage and current ratings a charge controller or inverter needs for a PV array, from the panel specs, temperature coefficients and site temperature extremes. - [PRO] Solar cable and fuse selection calculator. Picks the conductor sizes, string fuse and disconnect ratings for a PV array under NEC or IEC rules. - RMS Converter. Converts between peak, RMS and peak-to-peak voltage or current for seven waveform shapes, and reports the crest factor and average value of each. - New pinouts: Ethernet PoE, ATmega328P, ATtiny85, ATtiny84A, ATmega32U4, ATmega4809. Big thank you to everybody who subscribed or purchased the PRO version. Your support helps to make this app even better. If you like this app, please rate it and leave a review. Regards, Rostyslav
