7.4 ARK 2.5H-A1

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.
ØMonitoring: voltage, current and temperature detection of both single cells and
battery system.
ØProtection and Alarm: protection and alarm when overvoltage, under voltage, over
current, over temperature or under temperature occurs. See Appendix I for the details.
ØReport: report all alarm and status data to PCS.
ØSeries connection: support two to ten packs in Series connection.
ØPower failure triggered by fault: 10 minutes after the battery system and PCS
communication is disconnected or 15 minutes after undervoltage protection.
When installing or using a battery system, the safety information contained in this
section must always be followed. For safety reasons, it is the installer's responsibility to
be familiar with this manual and all warnings before installation.

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.
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.
Step 4: Fix the battery on the wall mount, make sure that the battery will not shake,
and then lock the safety screw.
Ø
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 minimum distance between the wall and the battery
is 300mm.
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 screws to
secure the anti roll over plate.
Step 3: Stack the battery on the base, connect the fixed connecting strip between the
battery packs.
Step 4: Make sure the battery will not shake, and then lock the safety screw.
ØIf more than 4 batteries are used , base mounting is recommended.
For floor installation with base , the maximum stack number of the
battery is ten. But if the battery number is greater than six , we
recommend stacking them in two lines.
The safety part needs to be installed at the top battery, however, once
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.

ØMethod 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
ØThe performance will be limited when the temperature is below 0°C.

Bar code number position：
XXX X XXXX XXXX XXXX
The 13th to 16th digits repres ent the serial number , base 34 ,
from 0001 to ZZZZ , automatically return to 0 every week
The 9th to 12th digits repres ent the production date , a total of 4 digits ,
s uch as in the 38th w eek of 2013 is 1338
The 5th to 8th digits re pre s ent the supplier . G RO WA TT is 0000 , other
outs ourcing suppliers refer to the corresponding relations hip of the s upplier code
The 4th repres ents the s oftw are vers ion code , refer to G RO WA TT controlled
"S oftw are code his tory table"
The 1th to 3th digits indicate the product code : refer to the product naming table and code
corres pondence table for details
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.
