TODO:
- monitor current by checking (small resistance) resistor voltage
- monitor voltage
- high voltage capacitor in input (2x max DC input)
- supercapacitor on output as battery replacement (>50F)
- analyze maximum power by performing series of measurements of voltage and current
- 2 PWMs: charging supercapacitor/battery, heater resistor
- charge capacitor/batteries till set voltage (voltage should be changeable remotely)
- optional: third PWM to charge capacitor/batteries to charge them, something like online hybrid UPS
