1.1 Intended Use
The entire ARK Hig h Voltage Ba tt er y System in cl ud es a HVC 60050-A1(high voltage
controller) and multiple ARK 2.5H-A1 (battery pack).
Each ARK 2.5H-A1 consists of 50A h c el ls wh ic h form 51.2V voltage battery pack via one
parallel and s ix te en s er ia l co nn ec ti on (1P16 S) . Two to ten ARK 2. 5H -A 1 ca n be connected
in serial to extend the capacity and power of energy storage system.
The ARK battery system powers the loads th rough PCS at nighttime without solar; when
solar b ec om es available du ri ng daytime, solar energy powers t he loads as a priority and

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.
Ø Monitoring: voltage, current and temperature de te ct io n of b ot h si ng le c el ls a nd

Ø Protection and Alarm: pro te ct io n an d al ar m wh en o ve rv ol ta ge , un de r vo lt ag e, o ve r
current, over temperature o r un de r te mp er at ure occurs. See Appendix I for the details.
Ø Report: report all alarm and status data to PCS.
Ø Series connection: support two to ten packs in Series connection.
Ø Power failure triggered b y fa ul t: 1 0 mi nu te s af te r th e ba tt er y sy st em a nd P CS
communication is disconnected or 15 minutes after undervoltage protection.

the number of the battery pack is higher than 7, one more safety part
should be installed in the middle battery which is shown the last step.
Ø Do not forget wear ESD wrist strap and gloves, safety gloves and
goggles.
4.3.3 Floor Standing Installation
Fig 4.8: Floor standing installation process
Ø Step 1: Place the battery base in the area to be installed, and mark the position of the
installation hole with a marker. The m in im um d is ta nc e be tw ee n th e wa ll a nd t he b at te ry
is 300mm.
Ø Step 2: Select an alloy drill with a diameter of 10mm and drill a mounting hole at least
60mm deep in the wall. Insert the expansion pipe into the hole and screw in the screw s to
secure the anti rol l ov er p la te .
Ø Step 3: Stack the battery on the base, connect the fixed connecting strip between the
battery packs.
Ø Step 4: Make sure the battery will not shake, and then lock the safety scre w.
Ø Step 1: Please make sure that the weight capacity of the wall should exceed 150kg.
Ø Step 2: Put bracket on wall and mark drilling spots. Keep a minimum distance of
300mm between the wall and bracket; a minimum distance of 500mm between bracket
and ground.
Ø Step 3: Choose an alloy drill with a diameter of 8mm, and drill at least 60mm mounting
holes in the wall. Clean the soil and insert the expansion tube into the hole, then screw in
the screw to fix the wall mount.
Ø Step 4: Fix the battery on the wall mount, make sure that the battery will not shake,
and then lock the safety screw.

Ø Before re pl ac in g th e ba tt er y, use the charger to charge the new battery
and the existing battery to full (SOC 100%).
Ø If the battery is not used, it is recommended to charge and discharge
the battery every 3 months to activate the chemical characteristics, and
the maximum interval shall not exceed 6 months.

Ø Method for calculating rated capacity:
Rated capacity of the measured module: 45 Ah
Number of modules connected in series: 2~10
Calculated rated capacity (Ah) = 45 Ah *1 =45Ah
Ø The performance will be limited when the temperature is below 0°C.
