Strong Points
Function
SUNSYS HES XXL is a complete and ready to use outdoor high power energy storage system for on-grid and off-grid applications. It supports dedicated applications such as optimization of photovoltaics with self-consumption, peak shaving, backup power and EV charging infrastructure.
This system is based on standard cabinets: a converter cabinet (C-Cab XXL), a battery cabinet (B-Cab XXL) and a master control cabinet (M-Cab) enabling a large variety of configurations in a simple and safe way.
It is perfectly adapted to large scale commercial and industrial installations as well as front of the meter projects.

Advantages
High safety standards
SUNSYS HES XXL integrates advanced power conversion and LFP battery technologies to create a winning formula. The battery cabinet uses liquid-cooled thermal management, with an integrated fire safety system, and meets the requirements of the latest international fire code.
The complete system is certified to the latest UL9540, the safety standard for energy storage systems in both Canada and the USA.
Extreme scalability
Large variety of system configurations are available based on three standard cabinets:
- C-Cab XXL: Converter Cabinet from 0.5 to 1.5 MVA
- B-Cab XXL: Battery Cabinet of 407kWh
- M-Cab XXL: Master Control Cabinet embedding smart components
While putting up to 4 systems in parallel it is possible to reach 6 MVA / 24 MWh.
Integrated ready-to-use certified system
SUNSYS HES XXL systems, including inverter, batteries and control cabinets, are certified and tested. Our systems have undergone a type-testing procedure to guarantee reliable behavior and performance, reducing the time and effort required for commissioning.
Specially adapted software for internal communication between all cabinets has been developed allowing efficient monitoring and control of the system, called PMS. Going a step further, we enabled thanks to SunSpec standard an easy integration with external EMS if you require it.
Whether you have a switchboard, solar system, generators or other equipment on site, our systems are designed to be compatible with a wide range of existing installations.
Enhanced Control, Faster Deployment, Safer Operation
EC‑Cab brings integrated control to SUNSYS HES BESS with a standardized, pre‑engineered architecture. By replacing custom control builds, EC‑Cab significantly reduces engineering & procurement efforts, costs, and lead times. EC‑Cab is EMS‑ready and supports EMS‑agnostic connectivity, enabling seamless monitoring and control with third‑party platforms.
