PRODUCT ADVANTAGES
Maximum returns at a lower total cost of ownership
An energy density of 83.6 kWh/m³ (306Ah cells) means you can load twice as much energy onto the same truck as with the previous generation – 3,556 kWh instead of 1,778 kWh. Transport energy is 91% higher, which directly cuts transport costs and the footprint required.
1778 kWh
Previous generation - 7 units
3556 kWh
STAR H-PLUS - 14 units
Quiet operation and easy management
At rated power, the system emits 65 dB, measured at a distance of one meter, so it doesn’t disturb the surroundings. The external button allows power-on in 10 seconds and power-off in 30 seconds, with system status visible directly on the front panel.
- Power-on 10 s · power-off 30 s
- Status display: Run · Warning · Fault · ON/OFF
- Quick setup on a level surface, no foundation required
Simplified maintenance, lower operating costs
An independent electrical compartment with front access, standardized quick connectors, and single-step component replacement cut service work down to minutes.
- Maintenance-free combustible gas detector for 10 years
- Automatic coolant refill - fewer service visitsAutomatic coolant refill - fewer service visits
- No UPS required
- App-based configuration, Master-Slave setup in 5 minutes
PRODUCT ADVANTAGES
Frequency regulation and uninterrupted power supply
The system supports aFRR, mFRR, and FCR. The response time for a single unit is under 200 ms, and under 250 ms for the entire system. With automatic grid/island switching (STS), it ensures uninterrupted power even during outages.

Technical specifications
Is a concrete foundation required for installation?
No. The STAR H-PLUS is designed for installation on a level surface with no foundation required, shortening installation time and lowering construction and land costs.
How many units can I connect into one system?
Up to ten units in parallel via Master-Slave integration, giving 2.54 MWh with 306Ah cells or 2.61 MWh with 314Ah cells. Configuration is done via the app and takes five minutes to set up.
How noisy is the system during operation?
At rated power, the system emits 65 dB, measured at a distance of one meter.
Does the system also work during a grid outage?
Yes. With automatic grid/island switching (STS), it ensures uninterrupted power, so a separate UPS isn’t required.
What does maintenance involve?
Standardized quick connectors allow single-step component replacement, access is from the front, coolant is refilled automatically, and the combustible gas detector requires no maintenance for ten years.
In which countries is the system certified?
It complies with grid codes in 45 countries, including Slovenia, Germany, Austria, France, the United Kingdom, the Czech Republic, Poland, and the Nordic countries. It holds six global product certifications (IEC 62619, IEC 63056, IEC 60730-1, IEC 62477-1, IEC 61000-6-2 & 6-4, UN 38.3).
