SunEnergyXT 500
Your Complete Solar Powerhouse
5 kWh storage, 2,400 W output, 4× MPPTs. All in one unit. Just plug in and power up.
5 kWh | 2,400 W | Local control
5 kWh | 2,400 W | Local control
Three Devices. One Unit.
Most solar storage systems require separate components. The SunEnergyXT 500 integrates everything.
4× 625 W MPPT Solar Charge Controllers
Connect directly to your solar panels and optimise energy harvest from each panel independently.
2,400 W Bidirectional Inverter
Converts stored DC power to household AC (230V) power and also charges the battery from the grid when needed.
5 kWh LFP Battery
Premium 314 Ah EVE cells that store enough power to get an average household through the night.
Start Small. Scale Big.
Start with a single 5 kWh unit on your balcony. As your needs grow, simply stack more units up to 30 kWh per battery tower.
30 kWh
1 head + 5 extension = 30 kWh storage & 800 W / 2,400 W output
Maximum single-system capacity
More than just capacity. A new dimension of energy scaling.
Why just expand your storage when you can multiply your output power as well? Discover the world's first system featuring Multi-Head Technology: Scale capacity, MPPT input, and output power simultaneously.
The end of compromises: Multi- Head Parallel Connection.
Most systems only allow for extention units that expand battery capacity (kWh), leaving the output power of the inverter as the bottleneck. Our system breaks this barrier. By cascading multiple head units, your system grows in every aspect:
Doubled/ Tripled Output Power
Scale from 2.4 kW to 4.8 kW, and up to an impressive 7.2 kW (32A), also in off-grid operation.
MPPT Boost
More head units equal more MPP trackers. Maximize your PV energy production, even with complex roof structures and alignments.
Limitless Flexibility
Stack the head units using our custom mounting bracket or place them separately in your household. Each unit can be individually expanded with additional battery units.
Maximum Power
Up to 7.2 kW (32A) – Powerful enough for demanding household appliances.
True Redundancy
Multiple head units ensure the highest reliability and failsafe operation for your home.
Modular Design
Start small and expand as needed – for both capacity and power.

One System. Multiple Use-Cases.
The SunEnergyXT 500 is one of the most versatile solar battery systems with use-cases rangingfrom a basic energy storage for balcony power plants to full-scale home storage setups.
Balcony Power Plant
Apartment dwellers
Renters
The easiest way to start producing your own solar energy. Mount panels on your balcony, plug in the SunEnergyXT 500, and watch your electricity bill shrink.
- No electrician needed.
- Compact enough for any balcony.
- Store excess energy for the evening and night.
Home Storage
Homeowners with existing or planned rooftop solar
Maximize your self-consumption. Store what your roof produces during the day and use it when you need it most.
- Stackable to 30 kWh for full home coverage.
- AC-coupling lets you integrate with your existing rooftop solar system.
- Zero feed-in mode prevents wasting your energy to the grid.
Solar Carport
Homeowners with EVs or multiple vehicles
Turn your carport into a solar power station. Generate, store, and use energy right where you park.
- Combine with the SunEnergyXT SolarDRIVE Carport.
- Supports EV charging via parallel operation (up to 7.2 kVA).
- Off-grid capable for fully independent operation.
Emergency Backup
Users concerned about grid reliability
outdoor/remote applications
When the power goes out, you stay on. UPS mode switches in 10 ms and your fridge, router, and lights never even notice.
- UPS mode for critical devices.
- One-Click-Black-Start: turn on all parallel units with a single switch.
- Full off-grid island mode for extended outages.
Full Control, In Your Pocket.
The SunEnergyXT app allows you to monitor and control your system wherever you are.
Unlock the full potential of your system by downloading the app.
Real-Time Monitoring
See PV input, battery status, grid feed-in, and house hold consumption live.
Firmware Updates
Over-the-air updates keep your system current.
Zero Feed-In Mode
Automatically adjusts output to match your house hold demand with a response time as fast as 1 second (local mode).
Home Assistant Integration
