🌞 Solar Input Options (Important for GR Sport Owners)
This system includes a RED Anderson solar input plug mounted on the front of the BCDC bracket for easy solar connection on standard 300 Series grilles.

If you have a GR Sport with the honeycomb grille, the front-mounted solar plug cannot be used due to grille clearance issues.
Instead, we will supply a dedicated under-bonnet solar mounting bracket so you can still run portable solar panels safely and cleanly.

FAQs

What is the difference between this kit with the jumpstart feature and your other 300 Series kit?

This version uses the REDARC Alpha DC-DC charger, which adds premium features including a built-in jumpstart function, start battery maintenance, Green Power Priority charging, and adjustable alternator amperage draw. The standard kit uses a REDARC Classic charger and does not include these features.

How do I use the jumpstart feature?

It’s controlled entirely via Bluetooth through the REDARC app on your phone. Simply connect to the charger through the app, follow the prompts to enable jumpstart mode, and the system will safely direct power from your auxiliary battery to your starter battery.

I have a GR Sport, will solar through the grille work?

No, on the GR Sport model solar through the grille won’t work due to the factory front design. You can instead choose an under-bonnet solar input or a roof-mounted solar connection.

I want to tow my caravan, can I add towing electrics to this kit?

Yes. You can add an isolated Anderson plug, an electric brake controller, and ESC compatibility. Just select the towing bundle when ordering, and everything will be integrated into your install.
