Thunder TDR02020 DC-DC 20A Charger with MPPT Solar Regulator

Thunder helps take you places you've never been before, making adventure more affordable and accessible for 4WD enthusiasts. The TDR02020 is a 20A DC-DC charger with a built-in MPPT solar regulator supporting up to 300W of solar, designed for reliable dual battery management.

Product overview

Designed for the working adventurer, Thunder products have been tested and developed to handle anything you can throw at them without breaking the bank. Easy to install, the Thunder DC to DC charger is the smart way to charge your auxiliary battery, no matter your vehicle.

The Thunder DC-DC Charger utilises a unique pulse charging algorithm with the intelligence to determine the best charge rate for your auxiliary battery, excluding lithium, making it the perfect addition to any vehicle requiring the management of a dual battery setup. The built-in MPPT solar regulator manages solar panels at maximum efficiency, capable of handling up to 300W of solar at 25V, and the charger automatically switches to the solar input when the vehicle battery is turned off or the main battery drops to 12.2V.
