2. General Description
The MPPT RS is a solar charge controller intended to operate with a PV voltage of between 80-400V and designed to charge a
48V battery bank.
2.1. Features
Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, a fast MPPT algorithm will improve energy
harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPTs
tend to lock to a local MPP, which may not be the optimum MPP. The innovative SmartSolar algorithm will always maximize
energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency
Maximum efficiency of 96%. Full output current up to 40°C (104°F).
Flexible charge algorithm
Fully programmable charge algorithm, and eight preprogrammed battery presets.
Extensive electronic protection
Over-temperature protection and power derating when temperature is high.
Isolated PV connections for additional safety
Full galvanic isolation between PV and battery connections provide additional overall system safety.
Optional external voltage and temperature sensor
Wired connections are available for battery voltage and temperature sensing. The Solar Charger uses these measurements to
optimize its charge parameters. The accuracy of the data it transmits will improve battery charging efficiency, and prolong battery
life. The Smart Battery Sense and other VE.Smart networking features are not currently supported.
2.2. Interfacing and Communications
VE.Direct port and two VE.Can ports
Either communications port type can be used for a wired data connection to a GX device (e.g. Cerbo GX, Color Control GX) PC
or other devices. Note that only one port can be used at a time.
Device Display
A 4 line LCD back-lit display shows operational information including battery levels, solar yield, and system icons.
User I/O connector:
• Aux 1, 2 input
• Programmable relay
• Battery voltage sense (Vsense)
• Battery temperature sense (Tsense)
• Remote H & Remote L - Configurable
Bluetooth Smart built-in
The wireless solution to set-up, monitor and update the controller using Apple and Android smartphones, tablets or other
compatible devices.
Configuring and monitoring with VictronConnect
Configure with the VictronConnect app. Available for iOS, Android devices, as well as macOS and Windows computers. A
VE.Direct to USB accessory is required for Windows systems; enter VictronConnect in the search box on our website and see the
VictronConnect download page for details.
