Close the DC Disconnect * Confirm the AES Cabinet's DC disconnect is in the closed position (ON) and secure. 2. Power on the Auxiliary AC Input Circuit * To energize the system, provide power to the Auxiliary AC input through the grid, generator, or backup load panel. If none of these power sources are available, skip to step 3. * Close the AC breaker on the HV Box. 3. Blackstart (if applicable) * For systems without an initial AC supply, utilize the UPS system to Blackstart the cabinet by turning the UPS ON to provide temporary power for the cabinet's control system. * For systems without an initial AC supply, use UPS control to black-start the cabinet (control power energization). * The UPS is for short-term operation only. Promptly restore AUX AC power once available. 4. Cabinet Initialization * The Battery Control Unit (BCU) and LYNK II Gateway will power up and initiate a system startup sequence. * Ensure the battery side compartment door is closed during the startup process. * The green LED on the cabinet door flashes to indicate the system is Ready. * Allow up to 60 seconds for the LYNK/BCU to initialize and check internal systems. 5. Pre-Charge Circuit Activation * After initialization, the BCU engages the pre-charge circuit and provides power to start the inverter. * The BCU then closes its main contractors when the pre-charge process is complete, at which point the inverter will have full power. 6. Verify Cabinet Status * Confirm that the cabinet indicator LEDs indicate normal operation. * On successful startup, the status LED on the cabinet door will be solid green, indicating the system is in operation. * If the status LED does not become solid green or error indicators appear: * Connect your laptop running LYNK ACCESS to the LYNK II Gateway to diagnose the battery. * You can also refer to the troubleshooting section of the AES Cabinet manual for diagnostic steps. 7.

Attempting to parallel the DC outputs of individual battery cabinets can result in unbalanced currents, system instability, or potential damage to the equipment. **Failure to follow these instructions may result in equipment damage.** | **Do Not Parallel Battery Cabinets on the DC Bus** Each AES Cabinet is designed to operate independently and must connect to a dedicated inverter input. Do not combine or parallel the DC outputs of multiple cabinets, as this will result in unbalanced current flow, system instability, and equipment damage. **Parallel Inverters on the AC Bus** System scalability is achieved by paralleling inverters on the AC bus, not by paralleling the batteries. Each inverter has a dedicated battery cabinet in this design, and the inverter AC outputs are synchronized to support larger system loads. This ensures safe, stable, and balanced operation across all components. By paralleling the Sol-Ark 30K/60K-3P on the AC bus, you can design system configurations with up to 10 inverters and a total output of 300/600 kW. AC Inputs are paralleled on a common AC input (grid/gen) bus. The same applies to AC outputs on a load bus. Batteries feed the Sol-Ark 30K/60K-3P inverters independently. The scalability described in this document refers to inverter system-level scalability achieved by paralleling multiple inverters on the AC bus. In this configuration, each inverter operates independently with its dedicated battery connection, while the combined AC output of the inverters is synchronized on the AC bus to meet large power demands. This approach promotes balanced load sharing across all inverters. ![image-20250522-233627.png](https://docs.discoverenergysys.com/__attachments/a_076b1059aad970bb50a29158df886ff893aa53515bc9c06f18e3e9f5453af956/image-20250522-233627.png?cb=d9391b84f3674e39354b19a27e96a583) Parallel Multiple Sol-Ark 60K-3P on the AC Bus (up to 10 inverters) | **NOTE** | |----------------------------------------------------------------------------------------------------------------------------------------------------| | For instructions on paralleling multiple units, refer to the Sol-Ark C\&I Installation Guide and User Manual for the corresponding inverter model. | Systems can be configured with either one battery per inverter or two batteries sharing a single inverter.

Each inverter runs independently, allowing systems to scale as large as needed for energy shifting, peak shaving, or other grid-interactive applications. **DC Battery Wiring -- Two Inverters, One AES Cabinet** ![image-20250522-235755.png](https://docs.discoverenergysys.com/__attachments/a_ebcee584a3ef0579b632841ffe5bb8b860f613ac0985b748c19d88c85c2ebde5/image-20250522-235755.png?cb=a754e4e58e74e9023a9d2a68e98799ba) Inverter to Cabinet DC Wiring Each Sol-Ark 3P inverter has two battery input terminals, each rated at 50 A. The AES Cabinet connects to the inverter using: * Two positive and two negative #4 AWG conductors to each inverter. * Each conductor is protected by a 70 A fuse in the AES Cabinet's built-in DC distribution box. This setup ensures balanced current flow to each inverter's internal DC/DC converter and supports 30-60 kW continuous charge/discharge, depending on the inverter model. **Communication -- Two Inverters, One AES Cabinet** ![image-20251127-212804.png](https://docs.discoverenergysys.com/__attachments/a_4d66335883bd37e98432c9b4e3d340b58ef5f0f9cc3181dd052e9746f40407dd/image-20251127-212804.png?cb=a74e1c6647a2591df9be96f08cf8257a) Inverter - LYNK II - Cabinet Communication In a two-to-one configuration, a LYNK II Gateway is required for each inverter to enable real-time, managed (closed-loop) control. The AES Cabinet communicates with one Sol-Ark inverter through one LYNK II Gateway (may be included with the battery cabinet), and with a second Sol-Ark inverter through a second LYNK II Gateway. Wiring * Connect one cable from LYNK II #1 CAN port to the Sol-Ark inverter #1's BMS port. Connect a second cable from LYNK II #1's LYNK port to the J3 port on the AES Cabinet's High Voltage Box. On most AES Cabinets, a CAT6 cable is already connected to the J3 port on the AES Cabinet's High Voltage Box and is accessible from the LYNK II. * Connect a third cable from LYNK II #2 CAN port to the Sol-Ark inverter #2's BMS port. Connect a fourth cable from LYNK II #2's LYNK port to the J4 port on the AES Cabinet's High Voltage Box. |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **NOTE** | | You can use a splitter/combiner, as shown below, to connect two LYNK II Gateways to the J3/J4 ports on the AES Cabinet through a single cable. ![image-20260204-170828.png](https://docs.discoverenergysys.com/__attachments/a_218d4604688bb5976f644d649eba9ebbcba7d76216eaab20ec6d22f1259f425b/image-20260204-170828.png?cb=d4024906f1f231246688966161a4e723) | Configure LYNK II 1. Start LYNK ACCESS 2.5.0 or later and update both LYNK II Gateways to firmware to 2.5.0 or later. 2. Connect to the first LYNK II device. From the LYNK ACCESS software's LYNK tab, open the Cabinet Settings tile, enable Multi-LYNK, and set it as Primary. ![image-20251209-222004.png](https://docs.discoverenergysys.com/__attachments/a_4dca25a3300258d57f2b1e482607f2b55423f69ea3488f5aafcee157fd0a86af/image-20251209-222004.png?cb=4eeeed11e2fbd3f92ccc2ab66f85b86f) 3. Connect to the second LYNK II device, enable Multi-LYNK and set it as Secondary. To confirm the system is working correctly, check the battery charging current values on the inverter. If values are 50% of the max, then the 2:1 Multi LYNK configuration is successful. | **NOTE** | |-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | * Configure the LYNK II Gateways as specified. * In a two inverter/one AES Cabinet system: * If Multi LYNK is disabled in both LYNK II Gateways, only one of the connected LYNKs passes the AES Cabinet battery information to its inverter. * If Multi LYNK is disabled in one of the LYNK II Gateways and the other is enabled as Secondary, both LYNK II Gateways will pass AES Cabinet battery information to their respective inverters, potentially causing the charge or discharge current to exceed the maximum allowed (overcurrent) for the battery cabinet. * If Multi LYNK is enabled and both LYNK II Gateways are set as Primary, or both are set as Secondary, only one of them passes AES Cabinet battery information to the inverter. The charge/discharge current will be reduced by 50%. | The LYNK II communication link enables the inverter to receive real-time battery data, including state of charge, voltage, current, temperature, and charge/discharge limits, ensuring safe, accurate, and optimized operation. This setup enables two inverters to manage and monitor the battery cabinet, receiving real-time data for state of charge, voltage, current, temperature, and charge/discharge limits from each LYNK II Gateway. Two independent LYNK II Gateways ensure precise, safe, and optimized performance with dual inverters. --- version: "A - 3" language: "en" --- # Warning, Caution, Notice, and Note Messages Messages in this manual are formatted according to this structure. |----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------| | ![Manual black.png](https://docs.discoverenergysys.com/__attachments/a_e9696666a173c3c710f3f4f5f48fc2a9f5316708d51282962b1cda9a0f9314e8/dcdb56aa-f469-4b5c-8bfa-df13ea05c7ac?cb=4da9d49712f7002ebf6ac4bda1e6f589) | Additional information concerning important procedures and features of the product.

Attempting to connect multiple cabinets in parallel on the DC bus may result in unbalanced currents, system instability, or potential damage to the equipment. **Failure to follow these instructions may result in equipment damage.** | Connecting the DC outputs of battery cabinets in parallel is not supported. The AES battery cabinets are designed to operate as independent units, each with its own DC connections to the inverter DC inputs/outputs. Attempting to connect multiple cabinets in parallel on the DC bus may result in unbalanced currents, system instability, or potential damage to the equipment. --- version: "C - 2" language: "en" --- # Emergency Procedure **In case of fire or smoke** * **Immediately initiate emergency shutdown.**Use the system's E-stop button to shut down the battery energy storage system and isolate the battery cabinet from loads. The E-Stop button is designed to immediately isolate the battery cabinet from the inverter (PCS) by opening the high-voltage box's dual redundant contacts for both the positive and negative terminals. Once activated, the battery is completely de-energized and physically disconnected from all external conductors that leave the cabinet for total interruption of current flow. * **Evacuate the area.**Alert nearby personnel and evacuate to a safe distance. * **Call emergency services.**Contact the local fire department and inform them of lithium-ion batteries' presence and location. **In case of battery electrolyte leakage** * **Evacuate and ventilate.**Move all personnel from the affected area and ensure proper ventilation to disperse potentially hazardous fumes. * **Avoid contact with leaked material.**Use appropriate PPE (e.g., gloves, goggles, respirators) to prevent chemical exposure. * **Isolate the area.**Cordon off the area to prevent unauthorized personnel from entering. * **Contact a certified technician.**Arrange for safe cleanup and disposal of leaked materials by a trained professional, following local regulations for hazardous waste. **In case of electric shock** * **Immediately disconnect power (if it is safe to do so).** Safely reach the E-stop button, trigger the system's emergency shutdown procedure, and cut off power to the affected equipment. Do not touch the victim directly if they are still in contact with a live electrical source. * **Call emergency medical services.**Seek immediate medical attention for the individual affected. * **Do not touch the victim with bare hands.**If the power cannot be disconnected, use a non-conductive object (such as a wooden pole) to separate the victim from the electrical source. Ensure your own safety first. --- version: "C - 2" language: "en" --- # Emergency Shutdown Procedure In the event of an emergency, follow these steps to shut down the system safely. 1. **Press the Emergency Stop Button.** This immediately de-energizes the cabinet by disengaging the integrated contacts in the HVB, cutting power to the DC circuits, and preventing further power flow through the system. 2. **Turn Off AC Power at the Source.** After activating the Emergency Stop, shut off the external AC source circuit to fully isolate the system. This provides an additional layer of safety, ensuring the system is completely disconnected from all external power inputs. [Next Page](https://docs.discoverenergysys.com/llms-full.txt/1)
