BougeRV Li 30A PWM Solar Charge Controller 12V/24V with Backlit Display – Negative Ground Regulator for RV & Off-Grid

Compact, intelligent solar charging for off-grid power systems

Meet the BougeRV Li 30A PWM Solar Charge Controller, a compact regulator designed for 12V and 24V systems with negative ground. Its backlit display keeps essential data visible in dim environments, while its robust electronics support diverse battery chemistries and real-world setups like RVs and cabins. This regulator emphasizes practical monitoring and flexible compatibility, helping you manage your solar charging with clarity and confidence.

Real-time visibility day and night

The regulator cycles the PV input current and battery voltage on its main interface with a refresh every 3 seconds, delivering a dynamic readout you can trust. When idle, the larger screen softens to 50% brightness, making it legible in low light without glare. A backlit display helps you monitor exactly what the controller is doing and how much power is flowing from the solar array.

• Real-time PV input and battery voltage updates every 3 seconds
• Backlit, larger display for easy reading in dim light
• Clear readout of charging activity and power draw

Smart Li battery readiness and flexibility

Not just for traditional lead-acid, this PWM controller includes distinct icons for LiFePO4, other Li chemistries, and LTO on the LCD. With a setting geared to Li batteries, it can assist jumpstarting a deeply discharged Li pack and reduces the need for additional hardware when upgrading to lithium technology.

• Special icons indicate LFP, Li, and LTO on the LCD
• Li-friendly settings support appropriate charging and jumpstart assistance

Broad compatibility for diverse systems

Designed to work with a range of 12V or 24V batteries such as SLD, FLD, GEL, AGM, SLA, LiFePO4, ternary Li, and LTO. It provides programmable charging and maintenance routines to suit different chemistries, helping you steward battery health over time.

Power and safety for solar installations

With a max PV input of 55 volts, it can handle substantial charging duties: up to 4500 watts for 12V configurations or 900 watts for 24V systems. A neat wiring kit with three pairs of spade terminals supports straightforward, tidy connections. Remember to connect the battery first and never disconnect the battery while panels are active.

Use cases and practical setups

Ideal for RVs, off-grid cabins, and other remote power needs, this regulator is built to perform with negative-ground battery banks and mixed solar arrays. Its dependable regulation can contribute to steady energy during camping trips, workshops, or lakeside getaways.

What you get

Beyond the controller itself, the package includes essential hardware to help you set up quickly and safely, with clear visual feedback on the LCD and accessible wiring points.
