Renogy Wanderer Li — 30A Negative PWM Charge Controller
Overview
The Wanderer Li is a compact 12 V PWM solar charge controller designed for small off-grid systems.
It supports lithium and lead-acid battery types, offers real-time monitoring (via RS232 or the Renogy BT-1 module),
and delivers 4-stage PWM charging with multiple load modes to keep your battery and devices safe and reliable.
Benefits
Keep batteries healthier longer — intelligent charging and temperature compensation extend battery life.
Protect your devices — built-in electronic protections reduce the risk of damage from faults or improper wiring.
Save energy — very low self-consumption reduces parasitic drain on your battery bank.
Monitor remotely and troubleshoot faster — view charging status, parameters, and error codes with Bluetooth or RS232 connection.
Easy to use in many settings — multiple load modes and battery profiles simplify setup for RVs, cabins, boats, and trailers.
Features
30A PWM charge controller with 4-stage charging algorithm (PWM).
Supports multiple battery types: Gel, Sealed, Flooded, and Lithium.
Five selectable load control modes to match different power-use scenarios.
Real-time monitoring via integrated RS232 port and compatible with Renogy BT-1 Bluetooth module (works with DC Home app and Renogy ONE M1).
LCD screen showing charge parameters and error codes for easy diagnostics.
Dynamic temperature compensation for optimized charging based on battery temperature.
Rugged aluminum housing with built-in protections (overcharge, over-discharge, short-circuit, overload, reverse polarity, reverse current, temperature compensation).
Stable output to help prolong the lifespan of sensitive electronics.
