The Plasmatronics D2020N is a negative ground solar controller for up to 20 Amps of solar panels and 12, 24 and 48V batteries – with load switching.

Plasmatronics Dingo 20A Solar Charge Controller D2020N

The D2020N is a great Australian Made, robust, and very well-respected solar charge controller. It handles 20 Amps of solar panels (240W @12V, 480W @24V, 960W @48V), to charge batteries, with up to a 20 Amp separate load circuit. These are ideally adapted for 4×4 or Caravan use, and also great for Australian small solar setups, or for those solar projects around the house, farm, or commercial premises. Lots of great extra functions: generator switching, load switching, remote devices, and more. “Negative Ground” allows for the battery negative to be earthed to minimize electrical interference, if needed.
