Renogy Solar Charge Controller Rover 40A 12V24V Auto Parameter DC Input MPPT Charge Controllers for Solar Panels Adjustable LCD for Gel Sealed Flooded Lithium Battery
In Stock
A 40 A MPPT controller for 12/24V systems with a 4-button LCD, low-temperature charging cut-off with included battery sensor, lithium reactivation and a 20 A load output with timer and light-control modes. Bluetooth needs the separate BT-2 module, and its 100 mA self-consumption is among the highest, but it fits van owners who want a proven wired controller. The listing gives a maximum operating temperature of 113 ℉ (45 ℃) in its specifications but 149 ℉ in its features.

Features
- Superior MPPT Technology: Renogy MPPT Solar Charge Controller achieves a 98% conversion rate&99% tracking efficiency, ensuring maximum solar panel charging even in low-light or partial shade. Advanced MPPT algorithm rapidly adapts to changing conditions.
- All-Weather Solar Charge Controller: Renogy charge controller operates from-40°F to 149°F, with built‑in low‑temp protection and app‑adjustable cutoff. Supports Gel, AGM, Flooded&Lithium batteries – ideal for off‑grid solar systems in extreme climates.
- Full Protection Solar Controller: with rust/corrosion‑resistant build and complete electrical safeguards–reverse polarity, overcharge, over‑ discharge, overload, short‑circuit, and reverse current. Ensures durable, safe off‑grid power for years.
- Renogy Charge Controller: Smart algorithm with 12V/24V auto‑detection adapts to battery status, while 4‑stage mppt solar charging (Bulk, Absorption, Float, Equalization) for lead‑acid and 2‑stage for lithium, plus auto‑reactivation, ensures optimal health
- Connectivity: Renogy DC Home App lets you connect with your solar charge controller for solar panels to gain insight into real‑time data and 30‑day history. Easily adjust settings,update firmware, and set alarms via RS485 with BT-2 (sold separately).
