Off-Grid with Victron Energy
Energy solution independent of the power grid
An Off-Grid system is an energy solution that makes the user completely independent of the public electricity grid.
The system generates, stores, and distributes all necessary energy on-site, which is ideal for remote
areas, vacation homes, or for those who strive for complete self-sufficiency.
With Victron Energy's products, one can ensure a reliable
power supply year-round.
Important components and examples of Victron products for an Off-Grid system
Inverter/charger
The inverter converts the batteries' direct current (DC) to alternating current (AC)
for household use and can also charge batteries from various energy sources.
Victron offers a wide range of inverters suitable for both smaller
holiday homes and larger residences.
Example of product:
Victron MultiPlus-II 48/5000 – A combined inverter and charger that
delivers up to 5000 VA per unit. MultiPlus-II is a flexible and
powerful component that works in both single-phase and three-phase installations
and is ideal for Off-Grid systems of various sizes.
Solar Charge Controller
The solar charge controller optimizes energy extraction from the solar panels and ensures efficient charging of the batteries, even under varying weather conditions. Victron offers several models of MPPT (Maximum Power Point Tracking) solar charge controllers to meet different installation needs and maximize energy production.
Product example:
Victron SmartSolar MPPT RS 450/200 – An advanced solar charge controller that is ideal for large solar installations with high energy demands. It can handle input voltages up to 450 V and charging currents of 200 A, making it perfect for robust Off-Grid solutions.
Batteries – Victron's LiFePO₄ Smart Batteries
The batteries are the core of an Off-Grid system and crucial for storing energy when the sun isn't shining. Victron offers high-quality lithium iron phosphate batteries (LiFePO₄) that have a long lifespan, high capacity, and are designed to withstand many charge cycles. These batteries are available in both standard version and the new NG series, which has several improvements:
NG series -These batteries have improved monitoring of cell voltages and temperatures and allow for larger battery banks up to 385 kWh. They are available in 12.8 V, 25.6 V, and 51.2 V and have an IP65 protection class, making them robust and reliable for various applications.
Advantages of Victron's LiFePO₄ batteries:
High safety: Lithium iron phosphate is stable and safe batteries that reduce the risk of overheating.
Long lifespan: They can handle thousands of charge cycles, making them a reliable solution for long-term use.
Smart monitoring: Victron LiFePO₄ Smart batteries can be monitored via Bluetooth, allowing you to keep track of battery status and performance via your mobile phone.
Examples of products:
Victron LiFePO₄ 24 V/200 Ah Smart Battery – A reliable battery that is connected in series to achieve the correct voltage in a 48 V system.
Victron LiFePO₄ NG 48 V/100 Ah – A new battery model in the NG series with improved monitoring and the ability to build larger battery banks, specially designed for larger systems that require both capacity and
top-class safety.
Generator backup and automatic start functions
A generator can be integrated into the Off-Grid system as a backup source to guarantee power even during periods of low solar radiation. The generator is connected to the AC input of the MultiPlus unit, allowing for battery charging and power supply to loads simultaneously. MultiPlus automatically manages the switching between solar energy and the generator and can be configured to start the generator automatically at low battery capacity.
Example of product:
Victron MultiPlus-II 48/5000 – MultiPlus functions both as an inverter and a charger and integrates generator backup to ensure power supply when needed. By connecting the generator to the MultiPlus' AC input, the system is ensured to be comprehensive and flexible.
Control center and remote monitoring
With Victron's Cerbo GX, you gain full control over the entire system. Cerbo GX monitors all connected components and allows customization of energy management through a simple and clear app. With VRM (Victron Remote Management), you can also remotely control the entire system from your mobile or computer, providing security and full control over energy usage.
Example of product:
Cerbo GX is Victron's main unit for monitoring and controlling all components in an ESS or off-grid system. It collects data from solar panels, batteries, inverters, and other connected devices, giving you full control over the system's functions.

FAQs
It is important to carefully calculate your energy consumption to choose the right size of batteries and inverters. Victron Energy offers tools and products that help you optimize energy storage and ensure that the system meets your needs, even under high loads or adverse weather conditions.
Yes, Victron Energy products such as MultiPlus and Quattro can be integrated with a generator as a backup. This provides an extra level of security if the batteries are low and solar energy is insufficient. The system can automatically start the generator when battery levels drop to a certain level and turn it off when the batteries are fully charged.
Victron Energy offers advanced monitoring solutions such as Cerbo GX and the VRM portal. These allow you to monitor and control your system in real-time, get detailed information about energy consumption and charging status, and make adjustments to optimize operation.
Yes, Victron Energy products are modular and designed to be expandable. You can start with a basic installation and later add more solar panels, batteries, or components to increase the capacity and efficiency of your system.
