BougeRV MPPT Solar Charge Controller 40A Solar Panel Regulator 12V/24V | w/ Low-Temp Cut-Off APP Control Backlit LCD for LiFePO4, SLD, Gel, FLD, AGM, RV, Marine, Upgraded
In Stock
This 40 A MPPT controller pairs built-in Bluetooth with a backlit LCD, a low-temperature charging cut-off with included battery sensor, and reactivation of dormant LiFePO4 batteries. Its 10 mA self-consumption is the lowest listed, and its -31 ℉ to 149 ℉ (-35 to 65 ℃) operating range is wider than most, suiting lithium van builds in cold climates. The listing gives the maximum PV input as both 100 V and 95 V.

Features
Details from the BougeRV ISE218 Amazon listing:
- FULLY COMPATIBLE WITH LiFePO4: BougeRV Sunflow 40A MPPT solar charge controller features low-temp cut-off charging (below 32℉) to protect your LiFePO4, it can also restart or activate dormant 12V or 24V LiFePO4 turned off due to short circuits or over-discharged
- SMART LCD AND APP CONTROL: Sunflow 40 amp MPPT controller also features a remote app control, the range is up to 32 feet. Stay informed with the “BougeRV” APP that provides the solar panel, energy storage device and load status. The controller provides 3 modes for display operation, full-featured mode, no-load mode, and viewing mode, you can select the full-featured mode to modify all adjustable parameters via the screen button if you don't want to download an app
- HIGH-EFFICIENCY CHARGE: BougeRV Sunflow 40 Amp MPPT controller can adjust the charge current from 0A to 40A. BougeRV charge controller for solar panels, its high tracking efficiency is up to 99.5%, peak conversion efficiency is up to 99%, maximizing the solar panels' output. Adopting quality aluminum heat sink, the solar regulator can dissipate heat better and minimize the power lost under full load working
- ACTIVE SHIELD: Certified by CE and RoHS. BougeRV 40A MPPT renewable energy controller features a dual MOS circuit to prevent the reverse current and reduce the heat in operation. With 6 protections, over-temperature, open-circuit, short-circuit, overload, polarity reverse prevention circuit, flow backward of current protections
- TECH SUPPORT AND ATTENTIONS: System voltage:12V/24V. Wire specifications:15-8AWG. Max.PV input power:600W/12V, 1200W/24V. Max PV input voltage: 95V. Rated load current: 20A. Please connect the 12V/24V power to the solar power controller first to complete the recognition process and wake up the display. BougeRV promises an 18-month tech support for the 40 amp MPPT solar charge controller
- NOTE: Our products have been updated iteratively. There are currently two APPs, the new version(BougeRV APP) and the old version(Solar APP). The current digital manual is the new version. If you need the old version of the manual, please reach out to us
