1. 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.

1.3 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.
