Renogy Rover Li 30A MPPT Solar Charge Controller with BT-2

Short Product Summary

The Renogy Rover Li 30A MPPT Solar Charge Controller is a 12V/24V MPPT regulator that handles up to 400W of solar at 12V (800W at 24V), with the BT-2 Bluetooth module included so you can watch and configure it from your phone.

Why This Product

A PWM regulator throws away a large share of your harvest, and it gets worse on cold mornings and overcast days when panel voltage runs high above battery voltage. The Rover Li tracks the array’s maximum power point at better than 99% efficiency and converts that surplus voltage into charge current instead of heat. The Li in the name matters: it carries a proper lithium profile alongside AGM, gel, flooded and a user-defined setting.

Key Features

• MPPT tracking >99% – converts surplus panel voltage into real charging current
• 400W at 12V, 800W at 24V – room to grow the array later
• 100V maximum Voc – wire panels in series for longer, thinner cable runs
• BT-2 Bluetooth module included – live monitoring and setup from the Renogy app
• Lithium, AGM, gel, flooded and user presets – proper 2-stage lithium and 3-stage lead-acid charging
• Automatic 12V/24V recognition – manual selection for lithium banks
• RS485 Modbus – integrates with Renogy ONE monitoring

Ideal For

• Caravans, campers and off-road trailers upgrading from PWM
• Lithium house-battery builds needing a correct charge profile
• Systems growing towards a larger roof array
• Anyone who wants live solar data on their phone

FAQ

Does the Bluetooth module come with it?
Yes — the BT-2 module is included, so you can monitor and configure from the Renogy app out of the box.

Will it charge a lithium battery correctly?
Yes. It has a dedicated lithium profile using 2-stage charging, plus AGM, gel, flooded and user-defined presets.

How many panels can I run?
Up to 400W at 12V or 800W at 24V, with a hard limit of 100V open-circuit. Tell us your panels and we will confirm the wiring.

Does it work on a 24V system?
Yes — it recognises 12V and 24V automatically for lead-acid; lithium banks are set manually.

Can 4Matt Campers fit it?
Yes. We specify, supply and install Renogy systems in our Bellville workshop and deliver nationwide.
