Rich Solar RS-MPPT40 40 Amp MPPT solar charge controller for RV, van, cabin, marine, and off-grid battery systems

40A Strong solar charging capacity for medium-sized RV, cabin, marine, and off-grid battery systems.

12V / 24V Automatically detects common 12V and 24V DC battery system voltages.

100VDC Supports solar input designs up to the listed maximum solar input voltage.

MPPT Tracks solar input efficiently to improve charging performance over basic controller setups.

Product Overview

The RS-MPPT40 is designed for customers who need more charging capacity than a small entry-level controller without jumping into a larger 60A setup. It regulates solar power from the panels to the battery, helping manage charging safely and efficiently for 12V and 24V battery banks.

This controller is a strong fit for RV solar upgrades, camper vans, travel trailers, boats, cabins, sheds, remote buildings, and DIY off-grid power systems where reliable MPPT charging, battery compatibility, and built-in protection are important.

Built for Medium-Sized Solar Charging Systems

The RS-MPPT40 is made for battery-based solar systems that need dependable MPPT charging, flexible battery compatibility, and useful system visibility. It is a practical controller for customers building or upgrading 12V and 24V solar charging systems.

RV & Travel Trailer Solar A strong controller option for roof-mounted solar arrays and battery banks used for camping, boondocking, or extended travel.

Cabins & Off-Grid Buildings Useful for remote buildings, sheds, tiny cabins, and off-grid systems that need reliable solar charging.

Marine & Boat Power Works for compatible marine battery systems where solar charging, battery protection, and system visibility matter.

12V & 24V Battery Banks Supports common low-voltage DC battery systems used in mobile, cabin, solar, and backup power applications.

Key Features That Matter

This description keeps the focus on what customers need to know before buying: supported system voltages, battery compatibility, MPPT efficiency, display visibility, protection features, heat dissipation, and Bluetooth-module communication support.

Heat Dissipation & System Protection

A die-cast aluminum design helps dissipate heat during operation. Built-in electronic protection helps guard against reverse polarity, overcharging, over-discharging, overload, short-circuiting, and reverse current.

System Monitoring Made Easier

The LCD screen and multiple LED indicators display system operation information, customizable parameters, and error codes. That makes it easier to see what the solar charging system is doing without relying on guesswork.

The built-in RS232 port can communicate with a BT-1 Bluetooth module, giving compatible systems an upgrade path for mobile monitoring when paired with the right accessory.
