1.4.1 Leaking Batteries The ESP-BCU HL includes an auxiliary battery to maintain operation in the absence of an alternate power source. In case of electrolyte leakage from the auxiliary battery, it's imperative to prevent any contact with the leaked liquid or gas. Electrolyte possesses corrosive properties and can result in skin irritation and chemical burns.
• Eye contact: Rinse your eyes with flowing water for at least 15 minutes. Seek medical attention promptly. • Skin contact: Wash the affected area thoroughly with soap and water. Seek medical attention as soon as possible. • Ingestion: If the electrolyte is ingested, promptly induce vomiting. Seek immediate medical attention.

SW 1 1 and 2 This is a combination of two DIP switches: one rotary DIP switch and one slide DIP switch. Both switches are used according to the number of batteries, and the battery clusters. CAN/RS485 The DIP switch is used to select the communication mode Switch used between the BCU and the inverter, you can set it to CAN or RS485.
Conversely, when the AC Power Switch is in the "Off" position, it interrupts the flow of AC electricity to the battery control unit. AC Power Power cable connection designed to deliver alternating Socket current (AC) electrical power to the battery control unit. Connect this input to an AC outlet to provide energy to the BCU.
Feature This product is designed to enhance the capacity of energy storage systems. It is suitable for residential, commercial, and small industrial applications. The ESP-BCU HL has the following features: • Support for Multi-Cluster Batteries: This unit enables seamless connectivity for multi-cluster batteries, both in series and parallel configurations.
Installation Location Ensure that the installation location meets the following conditions: ⚫ The building is designed to withstand earthquakes as per the building code (when applicable). ⚫ It is far away from the sea to avoid saltwater and humidity. ⚫ The floor is flat and level. ⚫...
Personal protective equipment (PPE) When handling the battery control unit, the following safety gear should be worn. Installers must comply with the relevant requirements of UL1973, IEC 62040, and IEC 62619, or applicable domestic legislation and other relevant international standards. Insulated gloves Safety goggles Dielectric Safety shoes...
EndurEnergy does not provide cables for all situations, for special projects ask sales team. Mounting The ESP-BCU HL is designed as a rack mount type battery control unit, this adds flexibility on installation and modularity for different configurations. 5.2.1 Rack Mounting (R6 / R12) 1.

2. Adjust leveler feet (if included), lower each leveler unit it reaches the floor, make sure each leveler contacts the floor solidly. After lowering each leveler, use the carpenter's level / bubble level to confirm that the rack is level. Adjust levelers as needed to get level.
Page 18
4. Slide the battery control unit into the horizontal brackets of the rack. Ensure that each battery control unit or batteries are vertically spaced out by 1/3 U (0.583” / 14.82 mm) to facilitate heat dissipation. Utilize M6 screws to securely fasten the batteries in place onto cage nuts, with a maximum torque of 8.7 lb*ft.
5.2.2 Enclosure Mounting - (BU10/15/20/30) 1. Place the enclosure in the location desired (refer to the details about the installation location described in Chapter 4.2). The enclosure should be moved close to its installation location inside its shipping container before it is unpacked. The enclosure must be installed in a structurally sound area with a level floor that is able to bear the weight of the enclosure + the weight of the battery control unit + the intended number of batteries to be installed inside.

2. In order to secure the enclosure to the building structure for stability, adjust the 2x wall brackets by losing the screws, move the brackets to leave a gap of at least 0.5” between the wall and the enclosure to allow airflow and door opening. Tighten the screw brackets and attach both brackets to the wall with 2x adequate screws (M8 or 5/16”).

3. Fix the enclosure to the floor by using 4x adequate screws (M8 or 5/16”). Verify foundation for seismic installations.
Cable Connections of the Battery WARNING Although the ESP-BCU HL does not have any direct power connection with the high- voltage batteries, it will be installed beside them. Therefore, we encourage you to connect the cables in accordance with local installation laws and regulations. Before connecting the cables, ensure that the battery is turned OFF.
5.3.1 Battery Control Unit Grounding There is a grounding icon on the front of the battery that indicates the grounding screw of the battery, connect the grounding wire on this screw and make sure all the batteries grounds are interconnected, this ground shall also be connected to the bonding ground of the inverter or PCS where the batteries will be installed, the ground bonding system shall be installed as per NEC Article 250 or local regulations.

SW1 Slide DIP Switch Number of Battery Clusters Connected Clusters connected in Parallel Clusters connected in Series** - Standard WARNING: ** Typical application is to connect the clusters in parallel, for series clustering the voltage limit is 1000 VCD (18 batteries), never exceed this or the system could be damaged. Consult EndurEnergy if in doubt.
The rotary DIP switch on the ESP-BCU HL Battery Control Unit allows you to set the number of batteries in a group. Each position on the switch corresponds to a specific number of batteries, ranging from 1 battery to 16 batteries. The DIP switch has 16 positions labeled 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Step 4: Powering On • Plug the 220V power cable into the AC power socket. (The ESP-BCU HL is equipped with a built-in UPS battery that can provide continuous power for up to 3 hour if no power is available nearby.) •...
