Forget standard solutions when it comes to powering your property, farm or commercial infrastructure. You need a 48V-based system - the undisputed industry standard for highly efficient lithium storage systems. Your requirement is clear: you want to merge different energy sources such as the power grid and a backup generator into one intelligent unit that works absolutely faultlessly and fully automatically.

This is where the Victron Quattro 48V family takes over. As the most powerful partner in the Victron universe, the Quattro is far more than a simple inverter. It is the strategic head of your power plant, delivering power exactly where other systems have long since reached their physical limits.

The power station: The Victron Quattro 48/15000/200-100/100

When "a lot" is not enough, the Quattro 48/15000 comes into play. It is the undisputed heavyweight champion of the series and is used where other systems would have long since capitulated.

The highlights of the 15kVA giant:

• 12 kW of continuous power: With this beast, you can supply not just a house, but entire workshops or agricultural facilities. It can handle loads that are unattainable for normal inverters.

• Extreme 200A charging power: That's a statement. When your generator is running, this Quattro pumps up to 10 kW of charging power directly into your batteries. This minimizes generator running times and saves massive amounts of fuel.

• Enormous starting currents: With a peak output of 25 kW, it safely gets even the heaviest electric motors and compressors running, where smaller devices would immediately switch to "overload".

Stationary energy management: Why the Quattro 48V is the heart of your infrastructure

Anyone planning a 48V system thinks in terms of long-term infrastructures. The Quattro 48V is designed to control the complexity of these systems invisibly and absolutely reliably on three levels:

Level 1: The fully automatic network switch (input logic)

In stationary planning, flexibility is everything. Whether the electricity comes from the grid operator or from your backup generator - the Quattro acts as an intelligent switching station. It prioritizes renewable energies, uses the grid only when needed and starts the generator fully automatically in an emergency. All without manual intervention, all without flickering lights.

Level 2: The intelligent power boost (PowerAssist)

Modern large consumers such as heat pumps or electric car charging stations often push domestic connections to the limit. The Quattro 48V serves as a dynamic buffer here. It "supports" the weak grid with battery power as soon as demand exceeds your connection capacity. You make your power connection virtually stronger without expensive grid extensions.

Level 3: Strategic load prioritization (two AC outputs)

Real sovereignty means managing wisely in an emergency. The Quattro offers two separate AC outputs with different priorities:

• Critical loads (AC-Out-1): Internet, lighting, heating and cooling are connected here. In an emergency, these devices are supplied with power in 20 ms without interruption.
  
  With its PowerAssist function, the inverter and charger can contribute up to 15 kVA (i.e. 15000 / 230 = 65 A) to the output in times of high peak current requirements. This means: input power plus inverter power

• Non-critical loads (AC-Out-2): Large loads (e.g. pool pump, sauna) are automatically disconnected in battery mode to save your valuable reserves for the essentials. This output is switched off in battery mode.

Technical deep dive: A direct comparison of the 48V models

In this table you will find the technical cornerstones of your planning. All models are designed for tough 48V continuous use.

The hard facts: What can the Quattro 48/15000/200 do for you?

Behind the technical data of the top model are real application possibilities for your project:

• Continuous power (12 kW): This is your ultimate insurance for everyday use. A Quattro 48/15000 delivers 12,000 watts of continuous power - enough to supply an entire luxury home including all major consumers (kitchen, air conditioning, heating) at the same time.

• Peak power (25 kW): The brute "starting torque". The Quattro 48/15000 can handle up to 25,000 watts for short periods. This is crucial when starting heavy industrial machines or massive compressors that draw enormous currents when switched on.

• charging current (200 A): In a 48V system, this is a huge time advantage. 200 amps of charging current means that you can almost completely refill an empty 10 kWh battery in just one hour of generator running time. This saves fuel and spares the nerves of your neighbors.

• Transfer switch (100 A): The load capacity of your "control center". With a capacity of 100 A, the Quattro can transfer a massive 23 kW of power from the mains directly to your consumers while charging the batteries in parallel for the next emergency.

Quattro or Quattro-II: Choosing the right control center

• Victron Quattro-II 48/5000: The modern evolution. Slim, efficient and perfectly tailored to the current German grid standards (ESS system) in the home.

• The classic Quattro bolides (8k to 15k): When maximum power and extreme robustness are required. These are the indestructible power packs for agriculture, industry and large stand-alone systems.

Who is the Quattro 48V built for?

• Demanding homeowners: You want maximum independence with a large storage system and an additional emergency power generator for emergencies.

• Agriculture & trade: You need to protect cold chains, milking systems or server rooms from any power failure with an absolutely fail-safe system.

• Off-grid pioneers: You live far from the grid and rely on the sun and generator - the Quattro coordinates this interaction fully automatically.

The Victron ecosystem: your smart power plant

A Quattro only reveals its full intelligence as part of a team. It communicates seamlessly with the entire Victron cosmos:

• Cerbo GX: The brain that monitors all energy flows.

• SmartSolar MPPT: The charge controllers that harvest your PV energy highly efficiently.

• VRM portal: Monitor your system worldwide in real time via smartphone or PC.

Planning reliability from a professional at Verkauf-Bochum.de

You don't plan a system with 15,000 VA power "off the shelf". Where huge currents flow, correct cable cross-sections, the right fuse protection and error-free programming of the relay logic are important - especially when high-end components from Victron Energy form the heart of the system. Whether in a self-sufficient home or in a technically sophisticated Smart Home mobile home: A powerful Victron inverter requires precise engineering for maximum reliability.

This is exactly where we at Verkauf-Bochum.de are your partner. We don't just sell you the hardware, we support you as a technical authority in the design of your entire power plant. We make sure that your system does exactly what you expect it to do: function without compromise.
