Product vs. solution
A cabinet is a product. A working system is a project.
The unit arrives ready. Your site doesnβt. Everything around the cabinet is what we do.
Consumption analysis, so you donβt pay for capacity you wonβt use.
Integration with your PV, switchgear, metering and protection.
Application and coordination with your distribution system operator.
Permits and fire safety documentation, prepared for you.
Batteries, inverter, BMS, cooling and fire suppression. Factory-tested, grid-certified in 45 countries.
Control strategy based on how your site actually makes or saves money.
Installation and commissioning on your site.
Service and warranty handling in the EU.
One responsible partner for the whole system.
How we integrate it
From consumption data to a running system.
- Step 01Analyse
Your load profile, PV production and grid connection.
- Step 02Size
The configuration and number of units that fit your use case.
- Step 03Connect & permit
Documentation and coordination with the grid operator and authorities.
- Step 04Install
Connected to your existing electrical infrastructure.
- Step 05Commission
EMS control strategy configured for your goals.
- Step 06Operate
Monitoring, maintenance and support from a local partner.
Use cases
Where all-in-one storage pays off.
Peak shaving
Cut demand peaks and the grid fees tied to them.
PV self-consumption
Store surplus solar energy and use it when you need it.
Time shifting
Charge when power is cheap, use it when itβs expensive.
EV charging support
Charge vehicles without upgrading your grid connection.

Technology we selected
Technology we chose to stand behind.
As an integrator, we select technology independently. For this segment, we chose systems built on original CATL battery packs.
The systems are manufactured by CNTE, a CATL-backed energy storage company founded by one of CATLβs co-founders.
CATL.
Original CATL LFP battery packs, with 280 Ah and 530 Ah cells.
8β10k
8,000 to 10,000+ cycles, depending on model.
Liquid.
Liquid cooling for stable performance and a longer lifetime.
0.5P/0.25P
Two configurations: high output, or a longer 4-hour supply.
>1 MWh
Modular. Combine units beyond 1 MWh.
IECΒ·UN
Certified to IEC 62619, IEC 63056, IEC 60730-1, IEC 62477-1, IEC 61000-6-2/4 and UN38.3.
01What is an all-in-one battery storage system?
A complete storage system in a single cabinet: batteries, inverter, battery management, cooling and fire suppression. It is factory-tested and designed for fast installation on commercial and industrial sites.
02Why buy through an integrator instead of directly from the manufacturer?
The manufacturer supplies the unit. An integrator makes it work on your site: sizing, grid connection, permits, integration with your existing infrastructure, EMS setup, commissioning and local service, under one contract.
03Who manufactures the systems?
The systems are manufactured by CNTE, a CATL-backed energy storage company founded by one of CATLβs co-founders. They use original CATL battery packs.
04How much capacity do I need?
It depends on your load profile, PV production and goals. We start every project with a consumption analysis and recommend the configuration that fits.
05Can the system be expanded later?
Yes. Units can be connected in parallel: up to 10 STAR H-MAX cabinets or up to 14 STAR H-PLUS units, so capacity can grow well beyond 1 MWh.
06What is the difference between 0.5P and 0.25P?
0.5P delivers higher power for shorter periods, suited to peak shaving and trading. 0.25P delivers power over a longer period (around 4 hours), suited to self-consumption and energy supply.
07Where do you deliver?
We deliver to most countries of the European Union.
LET’S LOOK AT
YOUR SITE.
Send us your basic consumption data or just tell us about your site. We will tell you whether all-in-one storage makes sense for you and how it would be set up.
