This manual introduces the Energy zeroCO2XL.
zeroCO2XL is a large storage solution applicable to commercial, industrial and
utility scale plants, both new construction and as a retrofit for existing plants. It can
also manage entire energy communities.
The solution involves connecting an AC power source to 60 kW power converters
that can be scaled in a modular way to higher powers to manage the charging and
discharging phases of individual battery strings of
125 kWh, and parallelizable in turn obtaining storage of over 1 MWh, acting as a
diaphragm between the instantaneous load curve and the availability of the energy
source, two trends that for renewable sources are difficult to coincide.
Requiring an alternating current source as input, zeroCO2XL is compatible with
photovoltaic inverters, wind turbines and renewable or non-renewable electricity
generators.
The EMS on-board computer allows you to implement management logics
customized for the type of application: increase in self-consumption, peak shaving,
feeding energy into the grid in a controlled way following the daily energy price
curves in the electricity market.

6 - Definitions
1.0 DEFINITIONS
BESS: “Battery Energy Storage system”. Electrical energy storage system based
on electrochemical Li-ion batteries (LFP). Given the capacity of the individual
battery, the total number of modules used defines the capacity of the system.
BMS: “Battery Management System”. System for monitoring and managing the
charge /discharge of a Li-ion battery (LFP); allows entire strings of batteries to
charge and discharge in a balanced way, avoiding imbalances, in favor of the
efficiency of the system and the expected life for the modules themselves.
SOH: “State of health”. It is the percentage health status of a battery compared to
the condition of early life. SOH of a battery is physiologically reduced over its useful
life. SOH may suffer degradation over time in relation to non-optimal, prolonged and
/ or repeated conditions of use.
SOC: “State of charge”. The percentage of charge of a battery. The operating range
of the battery is delimited by a minimum SOC below which the discharge is not
forced , and by a maximum SOC beyond which the charge is not forced. SOC of
a battery can undergo a momentary reversible variation dictated by instantaneous
operating conditions such as operating temperature and working speed.
PCS: “Power Conversion System”. AC/DC conversion module for electrical power.
With an AC input/output and a DC output/input, the conversion can have a dual
direction, allowing, depending on the phase, to charge (to accumulate electricity )
or discharge the batteries (to self-consume by covering the loads and / or feeding
electricity into the network).
EMS: “Energy Management System”. Intelligent system for energy management in
the plant that monitors, collects instantaneous operating data downto the voltage
levels and temperature values of each cell, communicates with the devices and
coordinates their operation to make the entire system effective and efficient, allows
remote supervision and control through a web interface on a Cloud platform.
RACK: Standardized system for the physical installation of hardware, computer,
electronic or electrical components that make up the zeroCO2XL System.
The zeroCO2XL family racks are available in two distinct configurations for easy
installation, access, maintenance and security:
◦zeroCO2- XL System: for the containment Of Modules PCS Of Devices electrical
and functional organs to the system logic as well as to the management of
power.

3.0 INTRODUCTION
3.1 Product Presentation
zeroCO2XL is a large storage solution based on Pylontech H32148-C high-voltage
storage batteries (LFP). It is applicable to commercial, industrial and utility scale
plants, both new construction and as retrofits for existing plants. It can also manage
entire energy communities.
The solution involves connecting an alternating current power source to 60 kW
PCS power converters, scalable in a modular way to higher powers to charge and
discharge, at different times, strings of batteries of size 125 kWh and parallelizable
in turn obtaining storage of over 1 MWh. In this way zeroCO2XL manages the
charging and discharging phases of the storage system which can alternate
according to the needs and convenience: accumulate energy n and the moments of
surplus production (compared to the demand of the loads)
and make it available at times when demand is highest, acting as a diaphragm
between the instantaneous load curve and the availability of the energy source.
Requiring input a source exclusively in three-phase alternating current in low
voltage, zeroCO2XL is compatible with photovoltaic inverters, wind turbines
and generators of electricity from renewable or non-renewable sources in line with
their operating parameters.
The EMS on-board computer allows you to implement smart management logics,
customized, according to the type of application: increased self-consumption, peak
shaving, feeding energy into the grid in a controlled manner or following the daily
energy price curves inthe electricity market.
zeroCO2XL is particularly suitable for application scenarios that require high power
peaks, large energy storage to be implemented in new or existing plants, limited
installation space, reliability and long service life.

16 - Introduction
3.1.2 Working logic
When ordering, the system must be congured as follows:
1. One or more zeroCO2racks - BESS 125K (rack with storage batteries in variable
quantities depending on the power of the system and the expected storage).
2. One zeroCO 2 rack - XL System (rack for power management and conversion).
3. An energy meter (1) to be connected downstream of the exchange meter to detect
moment by moment the electrical energy withdrawn or fed into the network.
4. At least one energy meter (2) equal to the previous one but to be connected
downstream of the source of alternating current production to detect moment by
moment the electricity produced.
Caution. It is possible to connect up to three meters on the production side to
group diversied or physically distant sources (eg strings of photovoltaic panels
working on different inverters).
By measuring the energy produced and in exchange with the network, and always
knowing the status of the batteries through communication with each BMS, the EMS
controls the charge / discharge and calculates the load by difference, satisfying the
request. Depending on the desired working modes for the system, zeroCO2XL can
concentrate its operation on:
• Self-consumption: Consists in the dedicate the more possible the power Produced
from source to meet the demand of the load moment by moment.
• Peak shaving: the intervention of batteries and source of production one, allows you
to reduce the power Purchased from network in the Moments in which the cargo
Has One request higher, which results in a attening of the network withdrawal
curve.
• Energy trading: it consists in optimizing the feeding of energy into the grid during
the various price time slots, maximizing the resulting remuneration.
