The Most Exciting Advantages at a Glance
Plug-and-Play
Connect solar modules. AC cable from the storage unit to the socket. Done.
All-In-One
4× MPPT + 2,400 W inverter + 25 kWh storage in one system. With separate AC outputs for grid and backup.
More Power. More Capacity.
Scalable through additional main devices or expansion batteries.
Emergency Power Supply
UPS mode with 10 ms switching time.
Smart Control
App monitoring, local control, and integration with Home Assistant.
EVE Premium Cells
10,000+ cycles for long-term use.
Your Energy Center at Home
Direct communication with the smart meter for automatic energy optimization in the household.
Three Devices. One Unit.
Most solar batteries require multiple separate components and cause a cable chaos.
The SunEnergyXT 500 integrates the entire system into a single, clear, and modular housing.
4× 625 W MPPT Solar Charge Controllers
Direct connection to your solar modules. Each MPPT optimizes the energy yield independently – even in partial shading. Thanks to dynamic MPPT load distribution, unused power can automatically be balanced between the inputs. Thus, the maximum feed-in power of 2,500 W PV module power is achieved even when individual modules deliver less power.
2,400 W Bidirectional Inverter
Converts the DC power stored in the battery into 230-V household electricity and can intelligently charge the battery from the house network if needed.
25 kWh LFP Battery
The latest premium EVE cells (314 Ah) efficiently store energy to reliably supply an average household overnight with its own stored solar power.
Why 25 kWh? The Smart Difference Compared to Ordinary 2-kWh Systems.
While the competition relies on small 2-kWh storage systems, we have deliberately chosen massively more capacity.
Why? Because we are not just building for the moment, but for the next decades.
Larger Battery, Less Stress
A larger battery has to work less hard. Thanks to the 25 kWh capacity, the load on the cells in everyday life remains extremely low. This means less heat generation and minimal wear. The result is over 10,000 charge cycles – a purchase that lasts almost 30 years.
Real Reserves for Emergencies
What good is an emergency power system if the battery is empty after an hour? The additional 23 kWh compared to ordinary systems give you enough energy to operate the refrigerator, router, and important devices for hours or even days.
Ready for Dynamic Electricity Tariffs
The future belongs to dynamic electricity tariffs. Charge the large battery at night when electricity is cheap, and use it when prices rise. Your battery becomes a real investment that pays for itself faster – even on days without sun.
Start Small. Expand Big.
Start with 5 kWh on the balcony and expand up to 30 kWh per tower. Three towers in parallel result in a perspective of up to 90 kWh.
One System. Many Applications.
From balcony power plants to emergency power supplies: a modular system for various life situations.
Balcony Power Plant
The all-rounder for balcony and apartment
Feed in 2400W / 800 W grid-compliant and use up to 2,400 W locally.
Highlight: Feed-in and local backup power in one system

Highlight: Ideal for EV charging with own solar energy.
Emergency Power / Off-Grid
Supply even in case of failure
UPS switching up to 10 ms for critical household loads.
Highlight: Refrigerator, router, and light remain stably supplied.
Full Control. Local, Fast, Precise.
Control your energy system via app and local interfaces with high responsiveness.
Real-time monitoring
PV, battery, grid flow and consumption always in view.
No feed-in in 1 second
In local mode, the system reacts particularly quickly to load changes.
Home Assistant & Local API
Smart home integration without cloud compulsion via mDNS/TCP.
UPS mode
Seamless backup with very short switching time for critical consumers.
OTA updates
New features and improvements can be conveniently installed via app.
