Product Overview

1.1 Intended Use
The entire ARK High Voltage Battery System includes a HVC 60050-A1(high voltage controller) and multiple ARK 2.5H-A1 (battery pack).
Each ARK 2.5H-A1 consists of 50Ah cells which form 51.2V voltage battery pack via one parallel and sixteen serial connection (1P16S). Two to ten ARK 2.5H-A1 can be connected in serial to extend the capacity and power of energy storage system.
The ARK battery system powers the loads through PCS at nighttime without solar; when solar becomes available during daytime, solar energy powers the loads as a priority and store residual solar power into the ARK battery system.
1.2 Appearance
1.2.1 HVC 60050-A1 (high voltage controller)
The high voltage controller is composed of battery control unit, DC breaker, power supply and communication terminals. The appearance of the product is shown as below.

Dimension (unit: mm) 1.2.2 ARK 2.5H-A1 (battery pack)
ARK 2.5H-A1 consists of battery module (including cell and mechanical parts), Battery management unit (BMU) as well as power and communication terminals. Product appearance is shown as below.

Dimension (unit: mm) 1.3 Working Principle and Function
The ARK high voltage battery system is composed of a high voltage controller HVC 60050-A1 and battery pack ARK 2.5H-A1 in series. It contains electrochemical batteries, battery control units, battery management units, power and signal terminals, and mechanical parts.
Compared with other battery systems, it has better charging and discharging performance, higher charging and discharging efficiency, more accurate status monitor, longer cycle life and less self-discharge loss.
A single cluster system can connect 2 to 10 packs in series to increase the capacity and power of the battery system. The entire battery system communicates with the inverter through CAN communication, and the operation stability is high.

• Monitoring: voltage, current and temperature detection of both single cells and battery system.
• Protection and Alarm: protection and alarm when overvoltage, under voltage, over current, over temperature or under temperature occurs. See Appendix I for the details.
• Report: report all alarm and status data to PCS.
• Series connection: support two to ten packs in Series connection.
• Power failure triggered by fault: 10 minutes after the battery system and PCS communication is disconnected or 15 minutes after undervoltage protection.

➢ Barcode coding rules
Bar code number position：

1. The 1th to 3th digits indicate the product code : refer to the product naming table and code correspondence table for details.
2. The 4th represents the software version code , refer to GROWATT controlled “Software code history table”.
3. The 5th to 8th digits represent the supplier code. GROWATT is 0000, the supplier D is 0001, and other outsourced suppliers are 0002/0003… , and so on, please refer to the corresponding relationship table of the supplier code.
4. The 9th to 12th digits represent the production date, which is represented by 4 digits, the year is represented by the first 2 digits, and the week is represented by the last 2 digits, for example, the 38th week of 2013 is 1338.
5. The 13th to 16th digits represent the serial number, 34 base , represented by 4 digits, and the characters 0 to Z are used. I and O in the letters are discarded.
   For example, the product number is SD00.0002100, the product code is ARJ, the software version is 0, the supplier D is 0001, the production date is 21th week in 2021, and the first barcode of the work order is ARJ0000121210001.
