3.1 Response to emergency situations
The Phocos Any-Cell ESS-L comprises multiple cells that are designed to prevent hazards resulting from failures.
However, Phocos cannot guarantee their absolute safety.
Leaking batteries
WARNING: If the Any-Cell ESS-L leaks electrolyte, avoid contact with the leaking liquid or gas.
Electrolyte is corrosive and contact may cause skin irritation and chemical burns.
If one is exposed to the leaked substance, follow these steps:
•Inhalation: Evacuate the contaminated area and seek medical attention immediately.
•Eye contact: Rinse eyes with flowing water for 15 minutes and seek medical attention immediately.
•Skin contact: Wash the affected area thoroughly with soap and water and seek medical attention immediately.

www.phocos.com 4 | P a g e
•Ingestion: Induce vomiting and seek medical attention immediately.
Fire
In case there is a fire, always have an ABC or carbon dioxide extinguisher.
The Any-Cell ESS-L may catch fire when heated above 150°C.
If a fire breaks out where the Any-Cell ESS-L is installed, follow these steps
•Extinguish the fire before the Any-Cell ESS-L catches fire.
•Refer to your local AHJ to determine the best course of action in cases where it is impossible to extinguish the
fire, but you may have time to move the Any-Cell ESS-L to a safe area before it catches fire.
•If the Any-Cell ESS-L has caught fire, do not try to extinguish the fire. Evacuate the area immediately.
WARNING: If the Any-Cell ESS-L catches fire, it will produce toxic and poisonous gases.
Do not approach.
Wet batteries
If the Any-Cell ESS-L is wet or submerged in water, do not try to access it. First contact the local AHJ for advice on how
to proceed. If the battery has been recovered, and cleared by the AHJ, please reach out to your distributor or Phocos
for technical assistance.
Damaged batteries
WARNING: Damaged batteries are dangerous and must be handled with extreme caution. They
are not fit for use and may pose a danger to people or property.
•If the Any-Cell ESS-L seems to be damaged, take photos, pack it in its original container, and then return it to
your distributor.
•If the Any-Cell ESS-L is damaged, it may leak electrolyte or produce flammable gas. If you suspect your Any-Cell
ESS-L is damaged, immediately contact Phocos for advice and information.

5.0 Product Overview
The Phocos Any-Cell™ESS-L LFP Series (ESS-L) is a Lithium Iron Phosphate (LiFePO4) battery product with an
integrated BMS (Battery Management System). The Any-Cell ESS-L is shipped with features including CAN
communication, undervoltage, over-voltage, over-current, over-temperature, and under-temperature protection
functions. Users can expect reliable operation with the safety of an LFP system over a long cycle life. Energy storage
systems implementing the Any-Cell ESS-L are expandable; up to 8 Any-Cell products may be used in parallel to
increase storage capacity accordingly. Users can also expect seamless integration of their Any-Cell ESS-L with new
and existing Any-Grid inverters designed for 48V battery systems.
NOTICE: The Any-Cell ESS-L may only be used with the Any-Grid™48V series of hybrid inverters with
accompanying Any-Bridge™AB-PLC-CAN gateway and monitoring device. This device facilitates closed loop
communication between the Any-Grid hybrid inverter and the Any-Cell ESS-L, which is necessary for normal
battery operation. Failure to include an AB-PLC-CAN in the installation of the Any-Cell ESS-L will result in a
non-functioning system.
Please see 7.3 System Startup with Any-Grid for additional details on setting up the Any-Grid ecosystem.

5.2 CAN communication interface pinout (CAN1 & CAN2)
The Any-Cell ESS-L has four modular 8P8C communication connectors for CANbus communication. CAN1 is used
exclusively for battery-to-battery communication between the BMSs of Any-Cell units when in parallel. CAN2 is used
to communicate between the BMS of one or multiple Any-Cells and the Any-Bridge gateway device. For installers
creating custom communication cables, the pinout of an Any-Cell CAN port is shown below.
There is no difference between the two ports labeled CAN1 - they may be used interchangeably, and both connect
to the same CANbus node. The same applies to the two CAN2 ports.
