Performance data in detail: The technical foundation of your energy supply

Unique performance features for the highest demands:

PV performance highlights and critical limits at a glance:

Nominal battery voltage: Exclusively for 48 V systems, the basis for powerful and efficient energy systems.
Maximum charging current: An enormous 200 A enables even very large battery storage systems (>20 kWh) to be charged quickly and powerfully.
Maximum charging power: An impressive charging power of up to 11.5 kW reliably supplies even demanding consumers with solar power.
Extremely high efficiency: Up to 96% efficiency ensures that only a minimum of precious solar energy is lost during conversion.
Maximum PV voltage: A high PV voltage of up to 450 V open-circuit voltage (Voc) allows long module strings to be connected in series. This saves costs through thinner cables and reduces installation effort and power losses over long distances – ideal for ground-mounted systems.
Number of MPPT trackers: Four independent trackers, each of which optimizes up to 4000 W of PV power.
MPPT operating voltage range: The wide range from 65 V to 450 V enables early start of energy generation even at low solar radiation.
⚠️ Max. PV operating input current: Limited to 16 A per tracker.
⚠️ Max. PV short-circuit current (Isc): Must not exceed 20 A per tracker. Failure to observe this value poses a significant safety risk.

This concentrated power means pure serenity in everyday life. Let the heat pump run while the washing machine operates in eco mode and the batteries are still quickly recharged for the night. Even after a cloudy day, your storage unit is quickly ready again for all eventualities.

Intelligent control and system compatibility: The technological superiority of MPPT RS

Ultra-fast maximum power point tracking (MPPT): The advanced algorithm reacts extremely quickly to changing light conditions, such as those that occur when it is partly cloudy.
Multiple independent MPPT trackers: Four separate trackers optimize up to four different PV fields (e.g., east-west roof, different inclinations, or module types) individually, thus maximizing the overall yield of the PV system.
Advanced shading detection: The intelligent algorithm scans the entire power curve to find the global power point even in partial shading and does not remain at a local, lower-performance maximum.
Fully programmable charging algorithm: The multi-stage, adaptive charging cycle (bulk, absorption, float) can be precisely adjusted to the requirements of lead-acid and modern lithium batteries via the VictronConnect app.
On-board display & integrated Bluetooth: A clear display on the front shows the most important operating data at a glance, while the built-in Bluetooth allows easy configuration, monitoring, and firmware updates directly from your smartphone. 📱
PV insulation resistance monitoring: This crucial safety feature continuously checks the insulation resistance of the PV generator. In the event of a fault, the charging process is stopped and an alarm is triggered to proactively protect against major problems.
🛑 Incompatibility with PV power optimizers: The official manual expressly prohibits the use of PV power optimizers (e.g., from Tigo). Competing MPPT algorithms can lead to system instability, significant power losses, and irreparable damage to the charge controller.

Experience how intelligence makes your everyday life easier. While you check the performance data of your individual roof areas from your sofa via the app, the controller works unnoticed in the background to ensure that even the brief shadow of a passing cloud does not cause a drop in yield. It's the reassuring feeling of being in complete control while the technology takes care of optimization for you.

Strategic added value: Why the MPPT RS is more than just a charge controller

Superior design flexibility through high voltage: The ability to handle PV voltages up to 450 V is more than just a technical specification—it is a strategic decision that simplifies overall system planning, reduces cabling costs, and maximizes efficiency over long distances.
Uncompromising safety through galvanic isolation: Complete electrical isolation between the high-voltage PV side and the 48 V battery system is a fundamental safety feature. In the event of a fault, it prevents dangerous voltages from spreading, thus protecting the entire downstream system and users.
Extreme scalability for growing requirements: The synchronization of up to 25 units via VE.Can allows the charging power to be expanded to up to 288 kW. This offers enormous future-proofing and enables the construction of huge solar systems that grow with your requirements.

Consider this the foundation of your personal energy transition. You start today with a system for your home, secured by the highest safety standards, knowing that in the future you can easily expand the system to include a charging station for your electric car or the power supply for a small workshop. It is the strategic security of being well equipped for all future developments.

Typical areas of application: From self-sufficient homes to commercial enterprises

Large off-grid homes and properties: Perfect for self-sufficient homes with high energy requirements and complex PV systems, e.g., on multiple roof areas or as a separate ground-mounted system at a greater distance.
Grid-connected energy storage systems (ESS): As a core component in modern ESS for maximizing self-consumption and providing a reliable emergency power supply. Here, the MPPT RS effortlessly manages the large PV generators required for this purpose.
Small commercial & industrial applications: Ideal for providing reliable power to farms, off-grid telecommunications stations, or workshops that require a powerful and robust energy solution.

Imagine a self-sufficient farm where the water pumps and cooling systems for the harvest run reliably on solar power. Or a modern single-family home that stays warm and bright even during a power outage in winter thanks to intelligent storage management. The MPPT RS is the invisible hero in all these scenarios.

System optimization: Recommended accessories for full control and precision

Victron Cerbo GX: This communication hub is essential for realizing the full potential of the MPPT RS. It enables remote monitoring via the VRM portal, remote firmware updates, and advanced system functions such as Distributed Voltage and Current Control (DVCC).
SmartShunt or BMV-712 battery monitor: For highly accurate monitoring of the battery state of charge (SoC). This information is crucial for the system to make intelligent decisions, optimize battery life, and maximize performance.
VE.Can communication cable & terminators: VE.Can is the robust and fast protocol for communication between MPPT RS, GX devices, and other components. Two terminators are required at the ends of the network to ensure stable operation.

Frequently asked questions from practice: Answers from the Victron community

Why is only one of my four trackers producing electricity? This is often normal behavior, especially when there is little sunlight. The algorithm can concentrate the available power on one tracker to maximize its efficiency before activating other trackers. This is usually not a fault.
Is it better to buy one 450/200 or two 450/100? That depends on your priorities. Two 100 A devices offer redundancy—if one fails, the second continues to operate. However, a 200 A device saves space and is often easier to wire.
"Error 200" – What is the cause and how can I minimize the risk? This error indicates an irreparable hardware defect. Reports from the community show that it occurs frequently in systems where a non-communicating battery management system (BMS) abruptly disconnects the battery from the controller at high charging currents. The resulting voltage spike can destroy the MPPT RS. The use of a communicating overall system (e.g., with Victron Lynx Smart BMS and Cerbo GX) is therefore not merely a convenience option, but an essential measure for risk reduction.

Explained for beginners: The specific benefits of a high-performance controller

Intelligent "gearbox" for your energy: Think of the MPPT RS as the highly intelligent gearbox between your solar modules and the battery. It perfectly converts the high, fluctuating voltage of the modules into a stable charging voltage for your 48 V battery without wasting energy.
Simplified installation for large systems: The high input voltage of 450 V allows you to connect more solar modules in a string (in series). This means fewer cables, thinner cable cross-sections, and thus lower costs and less installation effort.
Maximum yield, even on difficult roofs: With four independent inputs (trackers), the device elegantly solves the problem of complex roofs with different orientations or partial shading. Each area is optimized individually to maximize the overall yield.

Installation & Commissioning: Safety-critical practical tips for installers

Careful and standard-compliant installation is the key to safety, longevity, and maximum performance. It is essential to observe the following points:

Installation location: Only install the device vertically on a non-combustible surface in a dry, clean indoor area. A clearance of at least 30 cm above and below the device is essential for air circulation.
Connection sequence: Follow the strict sequence: 1. Connect the battery, 2. Connect the communication cable, 3. Connect the PV generator.
Battery wiring & tightening torque: Use the double M8 connections for suitable cable cross-sections. Tighten the bolts to exactly 14 Nm using a torque wrench. Incorrect torque is a common cause of overheating and fire hazard!
Fuse & disconnect switch: The battery cable must be protected with a suitable 250 A DC fuse or circuit breaker. In addition, an external DC load disconnect switch at the PV input is mandatory for maintenance and safety purposes.
Warranty-relevant protection: Exceeding the maximum PV short-circuit current (Isc) of 20 A per tracker, especially in the event of reverse polarity, can destroy the device and will result in the immediate termination of the warranty.
