01
Retrofit instead of replacing
Your existing PV system remains the foundation.
500 PRO AC CORE adds storage on the AC side of your existing system. A working inverter does not need to be replaced as a precaution; compatibility is checked for your specific system.
02
Put surplus energy to use
Keep more of your solar power for your own use.
If export payments are low or unavailable, store your solar surplus for later use rather than sending it to the grid without making full use of its value.
03
Smart Meter
Manage your energy flows.
A compatible Smart Meter detects generation and consumption, providing the readings needed to charge the battery with solar surplus via the AC connection.
04
Expand modularly
Start with what you need. Expand later.

Our recommendation
One main unit is often enough to start.
For small to medium capacities, we initially prioritise a simple configuration. If you need more power later, you can expand to two or three main units.
Multiple main units
When capacity and power grow together.
Additional B500 batteries increase storage capacity. With technically approved system linking, further main units can also provide additional MPPT channels and power reserves.
Up to 7,500 W PV input power
Three main units approved for this setup provide up to twelve MPPT channels with a combined PV input power of up to 7,500 W. System output power is up to 7,200 W, depending on the approved configuration. Panel allocation, electrical limits and system linking require technical planning.
Up to 7.2 kW system power
Available total power depends on the approved device combination, grid connection, electrical protection and electrical planning.
More reserve for your home
Multiple main units provide additional power and backup reserves for larger loads and more demanding energy systems.
Parallel operation, total power and connection type depend on approved control systems, firmware, the grid connection and technical planning.
System architecture
More than capacity: plan main units together.
Expansion batteries primarily increase energy storage. With approved linking, additional main units can also increase power, the number of MPPT channels and system flexibility.
More system power
Depending on the approved system configuration, additional main units can increase power from 2.4 kW to up to 7.2 kW.
More MPPT channels
Each main unit adds four MPPT channels, providing more options for different orientations, partial shading and additional panel areas.
Flexible system architecture
Plan main units according to the required power and add compatible B500 batteries to meet your capacity needs.
Total power and connection type must be planned to match the grid connection, firmware, controls and system approval.
Why does the 500 series start at 5 kWh?
More storage capacity provides reserves for evenings, nights, backup power and later expansion. The right size depends on your consumption and energy source.
More storage capacity for everyday use
With 5 kWh nominal capacity, more energy is available outside daylight hours. According to the technical data sheet, the EVE LFP cells achieve more than 10,000 charge cycles under the test conditions specified there.
Backup for selected loads
Selected loads can be supplied through the separate backup output. Runtime depends on available capacity, state of charge and the connected load.
Plan grid charging
Depending on the product line, tariff and system configuration, the battery can be charged from the grid at selected times. Whether this is economical depends on your tariff, consumption and charging pattern.

Clearly explained
Key questions before choosing your 500 series system.
Product lines, energy sources, capacity, backup power and technical planning explained.
Which option suits my home?
SunEnergyXT 500 is the starter option with direct PV connection and up to 800 W grid feed-in. 500 PRO offers direct PV connection and up to 2,400 W grid feed-in. 500 PRO AC CORE is an AC-coupled retrofit storage system for existing PV systems, grid charging and backup power. All three product lines start with 5 kWh nominal capacity and offer up to 2,400 W at the backup output.
What exactly is SunEnergyXT 500 PRO AC CORE?
SunEnergyXT 500 PRO AC CORE is an AC-coupled retrofit storage system for existing PV systems. It offers 5 kWh nominal capacity (4.8 kWh usable), 2,400 W grid-connected AC power and up to 2,400 W at the backup output. Direct PV connection is only possible with the separately available, paid MPPT software upgrade. AC installation must be carried out by a qualified professional.
What are the requirements for AC CORE?
AC coupling, grid connection, electrical protection and the Smart Meter must suit the existing system. The manufacturer lists Shelly 3EM, Shelly Pro 3EM, Shelly EM-50, EcoTracker IR, EcoTracker P1 and bitShake as compatible energy meters. Planning and installation must be carried out by a qualified professional.
How do the Smart Meter and SunEnergyXT app work together?
The SunEnergyXT app shows PV input, battery status, grid feed-in and household consumption. The app supports firmware updates, zero export and UPS mode control. Local interfaces and Home Assistant integration are available for compatible smart home systems.
Why choose 500 PRO rather than 500?
Choose 500 PRO if you need up to 2,400 W grid feed-in rather than up to 800 W, or plan for higher household loads. The backup output is not a distinguishing feature: both SunEnergyXT 500 and 500 PRO offer up to 2,400 W backup power. The specific combination of capacity, PV and consumption should be checked.
Are an electric car, heat pump and installation included?
No. These requirements affect planning but are not automatically included with a product. For complex systems, we recommend getting advice before buying.
When do I need a qualified electrician or advice?
For AC coupling, Smart Meter, electrical protection, grid connection, electric car or heat pump requirements, have the specific design checked by a qualified professional before buying.
How far can 500 PRO AC CORE be expanded?
One main unit starts at 5 kWh. Up to 30 kWh is specified per tower. According to the manufacturer, a system can be planned up to 90 kWh using up to three main units, each with suitable expansion batteries. Multiple main units increase available power as well as capacity; connection and distribution require technical planning.
Can I keep using my existing PV system and inverter?
AC CORE is intended for AC-coupled retrofits of existing PV systems. A working inverter can generally remain part of the existing system. Compatibility between the Smart Meter, grid connection, electrical protection and control must be checked for your specific system before buying.
How do I activate direct PV connection on AC CORE?
The four MPPT channels are physically present. To use them, you need the separately available, paid MPPT software upgrade. Panels, wiring and electrical limits must also be suitable for the system.
