Please read and follow these instructions carefully: 

Warning 

This equipment should only be installed, operated by qualified personnel (electricians). The local safety regulations and relevant operating procedures must be followed during the installation, operation and maintenance of the equipment, otherwise the equipment may be damaged. The safety precautions mentioned in this manual are supplementary to the local safety regulations.

Caution

Do not short-circuit the Li-ion battery. Follow the positive (+) and negative (-) marks on the Li-ion battery and equipment and ensure correct use. Do not reverse the Li-ion battery. Do not dismantle, crush, puncture, open, or shred the Li-ion battery. Before removing or reconnecting with the running system, make sure to turn off the power and shut down the system to avoid the risk of electric shock. Do not expose the Li-ion battery to heat or fire. In case of fire, use a dry powder fire extinguisher. Do not dismantle any part of the system without contacting PYTES or PYTES authorized technical engineers. System failure caused by such actions will not be covered by the warranty. Before operating the inverter, ensure that all batteries have been started up.

The following precautions should be taken when working on batteries:
a) Shut down the power and loads before connecting or disconnecting battery terminals.
b) Do not wear any metal objects such as watches and rings.
c) Use tools with insulated handles.
d) Do not lay tools or metal parts on top of batteries.
e) Wear personal protective equipment.
f) Make sure the battery is well grounded. Contact with any part of a poorly grounded or ungrounded battery can cause electric shock and burns by high short-circuit current.

Operating Environment

• Battery operating environment requirements:
• Operating Temperature: -10℃~50℃(14℉~122℉)
• Relative Humidity: 20%-80%, no condensation
• Altitude: ＜4000m
• Site environment requirements: Away from heat source, avoid direct sunlight, no corrosive gases, no explosive gases, no insulating gases, no insulating conductive dust. Install in cabinet which shall not be opened without dedicated tools
• Install in a restricted access area.

Packaging, transportation, storage requirements

Transportation

Always check all applicable local, national, and international regulations before transporting Li-ion Batteries. During transportation, protect the battery from severe vibration, shock or squeezing, and from exposure to sunlight and rain. During the loading and unloading process, the battery should be handled gently to prevent it from falling, rolling and being subjected to heavy pressure.

• Relative humidity: 20%-80%, no condensation
• Altitude: <4000m
• Store the battery in a cool, dry place, away from heat sources and no direct sunlight.
• Keep away from conductive substances such as conductive dust

Installation and configuration

Installation preparation

Safety Requirements

• When the battery arrives at the installation site, it must be unloaded and stored properly and prevented from the direct sunshine and rain. Before installation, check if there is any component missing according to 1.1 product standard configuration and check whether the box appearance is intact;
• Carefully handling the unpacking to preserve the insulation coating on the casing’s surface.
• Please contact PYTES if there is any damage or missing of products and / or components.

Note: The grounding resistance should be less than 0.1Ω.

• Single battery:
  Connect the positive and negative terminals of the battery to the battery port of the energy storage inverter with power cables.
• Multiple batteries (Max number 14):
  The connection of multiple batteries is only permitted in parallel. Firstly, connect the positive and negative terminals of the batteries in parallel with the supplied flexible busbar (for up to three batteries, no additional accessories are required). Next connect the positive and negative terminals of the battery port of energy storage inverter to one of the batteries with power cables. But due to limitations in battery communication and power cables, a maximum of 14 batteries can be connected in parallel, and a busbar or junction box should be used for convergence. Regardless of the number of batteries in parallel, the standard charging and discharging current for a single battery remains the same, please refer to “Table 1-1”. The capacity can be increased by connecting the batteries in parallel, but due to the limitations of BMS and power cable, a maximum of 14 batteries can be connected in parallel and a busbar or junction box should be used for confluence.

Warning: Connecting batteries in series is forbidden, as it can create a high voltage that poses a hazardous shock risk.

Figure 5-1 Schematic diagram of power cable connection

Note: When multiple batteries are connected in parallel, in order to minimize the influence of the circular current, each battery can be connected to a busbar with power cable. The length, thickness, material, and resistance of the cables connected in parallel must be the same.

Warning: Batteries connected in series are forbidden, high voltage would lead to hazard shock

• Single battery:
  Select the corresponding port based on the communication protocol between the battery and energy storage inverter (RS485/CAN), and then insert the communication cable into the port.
• Multiple batteries (Max number 14):
  The communication between the master and the slaves is carried out in a cascade mode, wherein one battery acts as the master while the others are slaves. Please refer to the picture below for the cascade connection. Users need to insert the communication cables into the relevant link ports between the batteries and keep in mind that:
  1. Keep the master Port 0 free;
  2. Keep the end slave Port 1 free;

Communication cable connection instructions of Multi-Rack:
Connect the master battery of each rack to a hub with a standard communication cable. A Hub is required for to build up the communication between inverter and battery (more than 14 batteries or more than one rack)

Note: The system may not be able to communicate if not followed the instruction.

2. Connecting steps:
   Step 1: Insert the WiFi stick into the LoT Port on the battery panel.
   Step 2: Create an account on the cloud platform and bind the WiFi stick.
   Step 3: Pair the WiFi stick with a wireless network (see WiFi stick user manual for details)

Procedure of starting/Shut down the whole system

Make sure that all batteries have been powered on prior to running the inverter. This is to avoid battery shock by the in-rush current of the large capacitors of the inverter.

Power on Procedure
Step 1: Turn on all power buttons.
Step 2: Press only the master battery SW button for one second.

Please ensure that all batteries have been activated before turning on the inverter. This will help prevent battery shock caused by the inrush current of the large capacitors in the inverter.

Shut down Procedure
Step 1: Press and hold the SW button of the master battery for three seconds.
Step 2: Turn off all power buttons.
Please wait for all battery lights to go out before turning off the power buttons.

Note: Batteries must be placed in a locked cabinet or room with a 25mm/1inch horizontal gap for ventilation between them. The battery cabinet needs to support the total weight of the batteries and necessary accessories.

Communication

The battery features RS-232C, RS-485, and CAN communication ports. The battery status can be obtained.

CAN
The CAN communication terminal (RJ45 port) follows CAN protocol, to output batteries information.
RS485
The RS485 communication terminal (RJ45 port) follows RS485 protocol, to output batteries information.
RS232
The RS232 communication terminal (RJ45 port) follows RS232 protocol, to upgrade the software and to communicate with your PC.
Link Port 0,1
The Port 0 and Port 1 communication terminals (RJ45 ports) follow the CAN/RS485 protocol for cascade communication between multiple parallel batteries.
LoT Port
4 Pin Circular Connector for connecting with WiFi sticks

Troubleshooting

Please refer to the troubleshooting methods mentioned below. Please read the “Table 7-1 LED indication” of this manual before troubleshooting to avoid false operations. For example, the blinking or constant red light of the ALM alarm on the front panel does not necessarily indicate a faulty battery. In most cases, the “alarm” indication signifies normal operation and requires no troubleshooting. Furthermore, if the battery indicates “protection,” it will resume normal operation automatically once the “protection” status is released.

Battery status	Protection / Alarm / Normal	ALM	RUN	Capacity LED	Descriptions
Shut down		OFF	OFF	OFF	All off
Power-on	Normal	ON	ON	ON	All lights stay on simultaneously for one second
Standby	Normal	OFF	Blink 1	OFF	standby
	Alarm	Blink 3	OFF	OFF	Low voltage
