2. IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS– This manual contains important instructions for SUNSYS HES L systems (see “Concerned
products”) that shall be followed during installation and maintenance of the storage inverter.
A potential Shock and Injury Hazard exists when working on or around electrical systems which could lead to serious
injury or even death. Only qualied competent personnel who have been trained in and are familiar with the Risk of Electric
Shock and Plasma Arc Flash Hazards may perform installation and maintenance on electrical systems. It is the sole
responsibility of the personnel doing the work to be fully cognizant of all necessary safety regulations and procedures and
be familiar with the installation instructions detailed in this manual.
CAUTION!
Any work carried out on the equipment must be performed by skilled, qualied technicians.
The input and output circuits are isolated from the enclosure; the system grounding, when required by
Sections 690.41, 690.42, and 690.43 of the National Electric Code, ANSI/NFPA 70, is the responsibility of the
installer
The wiring methods in accordance with the National Electrical Code, ANSI/NFPA 70 and Canadian Electric
Code (CEC) are to be used. All national standards applicable to batteries must be observed.
CAUTION!
Each power supply line must be provided with overcurrent protection according to the indication contained in
the present manual.
This inverter complies with Part 15 of the FCC Rules Operation so it may not cause harmful interference and
must accept any interference received, including interference that may cause undesired operation.
Overcurrent protection for the AC circuit is to be provided by the installer.
Before carrying out any operations read the SUNSYS HES L system instruction manual and Battery Energy

3. OVERVIEW
The information in this manual is provided to aid in the installation, operation, and maintenance of the SUNSYS HES L
energy storage system. Please read, understand and follow the procedures given to ensure trouble-free installation and
operation.
3.1. General description
The SUNSYS HES L is a fully integrated AC connected energy storage system that supports a host of applications such as
rming renewable production, stabilizing the electrical grid, controlling energy ow, optimizing asset operation and creating
new revenue which provides greater control, efciency and reliability across the electric grid. Another important function
of the system is to provide backup power in the event of a grid failure or during power quality anomalies, therefore we are
supplying the Island Mode version of the system.
The SUNSYS HES L system comprises two major cabinets namely, a converter for DC to AC conversion (referred to as
C-Cab) and the Battery cabinets (B-Cabs). The unit has been designed to operate natively outdoors, potentially making
installation simpler and not burdening the facility cooling and ventilation systems. This unique capability is facilitated by
utilizing liquid cooling loops for the batteries which minimizes the cabinet ow through air volume, facilitating internal
environmental control using ltered normal environmental air. The battery requires tighter temperature control for life and
performance, consequently the battery cabinets utilize an active chiller to control the temperature within closely controlled
limits to maximize battery life and performance. For the C-Cab we utilise proper air ltering and ventilation system in order
to keep internal ambient under controlled conditions. Active cabinet heating is also employed for low temperatures and
humidity condensation control.
The internal power ow between the modules of the system is controlled by a Power Management System (PMS), which is
integrated inside the C-Cab.
The SUNSYS C-Cab L, Shown in Figure 1, comprises the conversion modules of 50kVA each with their control, an optional
automation box that can contain the PMS and IoT devices, a DC part with protection and connection and an AC part with
protection and connection.

3.5. Topology
The SUNSYS C-Cab L has been designed to operate autonomously thanks to the PMS (with compatible batteries) or from
the external commands of a device called Energy Management System (EMS) which is not a part of this manual. The EMS is
provided by a third party and has full control over the Energy Storage System (ESS), our privileged partner for this offer is ETB.
