Renogy Rover Li 40 Amp MPPT Charge Controller

Renogy Rover Li 40A MPPT Charge Controller (with low temperature protection)

Renogy Rover Li 40A MPPT is an advanced charge controller that maximizes the yield from photovoltaic panels and ensures fast,
efficient battery charging in off-grid installations. Thanks to technology MPPT precisely tracks the maximum power point
of PV modules, and low-temperature protection increases work safety in cold conditions. The solid, resistant housing
reduces the risk of corrosion and dirt, additionally protecting the wiring. Built-in protection and efficient heat dissipation
support stable operation under load, and the function activation of lithium batteries helps get them back up and running when you need it.

Key benefits

• MPPT 40A - maximizing PV yield and faster battery charging.


• High efficiency - tracking efficiency up to 99%, conversion efficiency to 98%.


• Low temperature protection - safer charging in more difficult conditions.


• Activation of lithium batteries - "wake up" function for LFP batteries after deep discharge.


• Rugged housing and cable protection - lower risk of corrosion, dirt and damage to cables.


• Stable operation and cooling - fast heat dissipation when working off-grid.


• Monitoring and integration - optional Bluetooth (BT-2) and RS485 (Modbus) communication.

Main features

• Automatic system detection 12V/24V


• Possibility to configure charging profiles (Boost/Float) for the battery type


• Multi-level protection: overcharge, over-discharge, overload, short circuit


• Possibility of charging over-discharged lithium batteries


• Compatibility with Renogy DC Home app (with communication module)
