FAQs

Does this kit work with the Accelerate inverter/compressor bracket for the Prado 250?

Yes. This underfloor kit is designed to work perfectly with our inverter/compressor bracket system.

If you purchase both together, we will pre-mount the inverter mega fuse onto the battery tray for you to make installation even easier.

Can I run socket banks on both sides of the vehicle?

Yes. Simply add the Dual Socket Upgrade (add-on product) to your order.

This includes the Prado-specific Y-lead that safely connects both socket banks to the underfloor system.

Are instructions included with the kit?

Yes. Every kit comes with a full installation video and a detailed PDF instruction manual including wiring diagrams, photos, and step-by-step guidance.

Do I need to run any cabling from the engine bay to the rear?

No. This is a self-contained underfloor system.

All charging, fusing, solar input, and output wiring is located in the rear of the vehicle — there’s zero cabling run through the vehicle.

Does the REDARC Alpha 50A work in the Prado 250?

Yes — when limited to 40A.

We pre-program the Alpha 50A to a 40A limit, making it fully suitable for the Prado 250 while still offering faster charging and jumpstart capability.

Will this fit with drawer systems?

This kit is:

  • Compatible with RV Solutions (RVSS) drawer systems
  • Not compatible with the RVSS false floor (battery height clearance)
  • Not yet tested with other aftermarket drawer or false-floor systems

Does this kit work in both 5-seat and 7-seat Prado models?

Yes. The tray and wiring loom are designed to work with both seating configurations.

Will the 220Ah battery fit under the factory floor without raising it?

Yes. The custom tray is engineered specifically to house the underfloor 220Ah battery while retaining the factory floor height.

Does my Alpha DC-DC charger have temperature protection?

Yes. The Alpha DC-DC charger has intelligent thermal protection built in.

  • If the internal temperature exceeds ~55°C, the charger will gradually reduce output to protect internal components.
  • If the internal temperature reaches ~80°C, the charger will fully shut down to prevent damage.

Once temperatures return to a safe operating range, normal charging will automatically resume.
