Victron Quattro 48/8000/110-100/100 Inverter/Charger
The Victron Quattro 48/8000/110-100/100 is a premium 48V inverter/charger built for high-demand backup and advanced off-grid or hybrid systems that require two independent AC inputs, fast changeover, and strong surge capability.
What this product is
The Victron Quattro 48/8000/110-100/100 is a 230V single-phase inverter/charger that converts 48V battery power into stable AC power for your loads and can also charge the same 48V battery bank from an AC source such as the grid or a generator.
What this product is not
This Victron Quattro 48/8000/110-100/100 is not a solar charge controller and does not include a built-in MPPT, so solar charging requires a separate MPPT solar charger or a compliant PV solution in the system design.
This Victron Quattro 48/8000/110-100/100 is not a high-voltage battery inverter and is designed for a 48V nominal battery system (not HV battery packs).
Dual AC inputs with automatic source selection
A key advantage of the Victron Quattro 48/8000/110-100/100 is two independent AC inputs with an integrated transfer switch. This allows a system design like Grid on AC-in 1 and Generator on AC-in 2 (or two generators), and the unit automatically selects the active source.
Two AC outputs that reduce battery drain
The Victron Quattro 48/8000/110-100/100 includes two AC outputs designed for smarter load control:
- Main output: no-break output for critical loads, with fast transfer (less than 20 ms) so sensitive electronics can keep running during source loss.
- Second output: only live when AC is present on the input, ideal for loads you do not want to run from battery (example: geyser element or other non-essential loads).
PowerControl and PowerAssist
The Victron Quattro 48/8000/110-100/100 supports PowerControl and PowerAssist to manage limited grid or generator capacity more intelligently:
- PowerControl helps prevent overloading the grid or generator by respecting a configurable input current limit and prioritising loads.
- PowerAssist can supplement limited grid or generator power with battery power during short peaks, then recharge the battery when demand drops.
Battery system and compatibility
The Victron Quattro 48/8000/110-100/100 is designed for a 48V battery bank and is lithium-ion battery compatible. Correct battery settings and system design remain essential, especially for lithium-based batteries and BMS-managed installations.
Ideal applications
- High-end residential backup where fast transfer and strong surge support matter.
- Off-grid systems using a 48V battery bank and 230V distribution.
- Hybrid-style systems that need dual AC sources (grid + generator, or generator + generator).
- Installations that want an essential-load output plus a non-essential output that only runs when AC is available.
Limitations and system planning notes
- No built-in MPPT solar charging: PV charging requires an external MPPT or alternative PV integration.
- Designed for 48V nominal battery systems only.
- Anti-islanding details are not provided here: ensure compliance requirements are addressed in the final system design and approvals for your installation context.

FAQ
Frequently Asked Questions
What type of inverter is the Victron Quattro 48/8000/110-100/100?
The Victron Quattro 48/8000/110-100/100 is an inverter/charger. It converts 48V battery power into 230V AC power and can also charge the same battery bank from an AC source such as the grid or a generator. It is not an all-in-one solar inverter.
Does the Victron Quattro 48/8000/110-100/100 have a built-in MPPT solar charger?
No. This inverter does not include a built-in MPPT solar charger. Solar panels must be connected through a separate MPPT solar charge controller or another compliant PV charging solution as part of the system design.
Will this inverter work during load shedding or a grid failure?
Yes. When grid or generator power is lost, the Victron Quattro switches to battery power on the main output in less than 20 milliseconds. This fast transfer allows critical loads such as computers, routers, and lighting to continue operating without noticeable interruption.
What is the advantage of having two AC inputs?
The dual AC inputs allow two independent power sources to be connected, such as grid power on one input and a generator on the second input. The inverter automatically selects the active source, making it ideal for systems that rely on multiple AC supplies.
What is the purpose of the second AC output?
The second AC output is only active when an external AC source is available. It is commonly used for non-essential loads that should not run from battery power, such as a geyser element, pool pump, or other high-consumption appliances.
What battery systems are compatible with this inverter?
The Victron Quattro 48/8000/110-100/100 is designed for 48V nominal battery systems and is compatible with lithium-ion batteries when correctly configured. Battery settings and overall system design must match the battery manufacturer’s requirements.
Can multiple Victron Quattro units be combined?
Yes. Multiple Victron Quattro units can be connected in parallel for higher power output or configured in three-phase systems. This makes the platform suitable for scalable residential, commercial, and off-grid installations.
Is this inverter suitable for feeding power back into the grid?
Grid export capability depends on the overall system design, additional components, and local compliance requirements. This inverter supports advanced grid-interactive systems, but export is not automatically enabled by the inverter alone.
How is the Victron Quattro different from inverters like Deye or Sunsynk?
The Victron Quattro is a modular inverter/charger designed for professional and custom-built systems. Unlike Deye or Sunsynk inverters, it does not include a built-in MPPT or an all-in-one hybrid design. Victron systems use separate components such as dedicated MPPT solar chargers and GX control devices, offering greater flexibility, scalability, and long-term system control. Deye and Sunsynk inverters are typically all-in-one hybrid units that integrate MPPTs, inverter, and basic monitoring in a single enclosure, making them simpler to install but less flexible for complex systems.
Who should choose the Victron Quattro over an all-in-one hybrid inverter?
The Victron Quattro is best suited for users who want a premium, expandable system with advanced control, multiple AC sources, high surge capability, and long-term scalability. It is commonly chosen for high-end residential, commercial, marine, and off-grid systems where flexibility and reliability are more important than having everything integrated into one unit.
