MPPT vs PWM

MPPT controllers convert excess panel voltage into charging current, harvesting 15–30% more energy than PWM — and they let you run higher-voltage arrays on 12, 24, or 48V battery banks. Size the controller by array watts divided by battery voltage, plus 25% headroom: a 1,000W array on a 24V bank needs a 50A controller. Victron SmartSolar units add Bluetooth monitoring; Morningstar and OutBack remain the workhorses for unattended off-grid sites.

Pro Tips

  • MPPT pays for itself on arrays over roughly 200W
  • Amps equal array watts divided by battery volts, times 1.25
  • Match controller voltage to the battery bank: 12, 24, or 48V
