Rich Solar RS-MPPT30 30 Amp MPPT Solar Charge Controller
The Rich Solar RS-MPPT30 is a 30A MPPT solar charge controller designed for smaller and mid-size 12V or 24V battery-based solar systems. With automatic system voltage detection, support for Sealed, Gel, Flooded, and Lithium batteries, MPPT tracking efficiency up to 99%, peak conversion efficiency of 98%, LCD and LED system monitoring, electronic protections, load control, heat-dissipating aluminum construction, and RS232 support for the BT-1 Bluetooth module, it gives RV, van, boat, cabin, shed, and off-grid solar builds a smarter way to manage charging.
Product Overview
The RS-MPPT30 is designed for customers who want a more efficient solar charging controller than a basic PWM setup, without needing a larger 40A or 60A controller. It regulates power from solar panels to a compatible battery bank and helps maximize charging performance in 12V and 24V DC systems.
This controller is a strong fit for RV solar kits, camper vans, travel trailers, boats, cabins, sheds, small off-grid buildings, and DIY battery-based solar systems where reliable MPPT charging, system visibility, battery compatibility, and built-in protection matter.
Built for Smaller and Mid-Size Solar Charging Systems
The RS-MPPT30 is made for battery-based solar systems that need dependable MPPT charging, flexible battery compatibility, and clear system feedback. It works well as the controller foundation for many compact RV, van, boat, cabin, and off-grid charging setups.
Key Features That Matter
This description keeps the focus on the real buying decision: automatic voltage detection, battery compatibility, MPPT energy harvest, protection features, system monitoring, heat dissipation, load control, and Bluetooth-module communication support.
The controller automatically detects 12V or 24V DC system voltages, helping simplify setup for common battery banks used in RV, van, boat, cabin, and off-grid solar systems.
The advanced maximum power point tracking algorithm quickly locates the best working point in the I-V curve, helping improve system energy efficiency. With tracking efficiency up to 99% and peak conversion efficiency of 98%, it helps harvest more usable solar power from connected panels.
The RS-MPPT30 is compatible with Sealed, Gel, Flooded, and Lithium deep-cycle battery options. It also supports diverse load control and can charge over-discharged lithium batteries when used within the correct system setup.
The 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 for customers to understand what the solar charging system is doing instead of guessing from battery voltage alone.
The RS232 port can communicate with the BT-1 Bluetooth module, giving compatible setups a path to Bluetooth monitoring when paired with the correct accessory.
