1. Introduction The document describes the installation, commissioning, maintenance and troubleshooting of the following high voltage battery listed below. Mira-HV25 Note: Mira-HV25 = 2.45kWh High Voltage The battery chemistry of these products is Lithium Iron Phosphate. This manual is designed for qualified personnel only. The tasks described in this document should be performed by authorized and qualified technicians only. After Installation the Installer must explain the user manual to the end user. 2.
3. Safety Any work on the Batteries should be handled by authorized technicians and hence it is understood that the technicians should familiarize themselves with the contents of this manual before any maintenance or installation is carried out on the system. 3.1 Handling Do not expose battery to open flame. Do not place the product under direct sunlight. Do not place the product near flammable materials. It may lead to fire or explosion in case of accident.
Fire Situation In situations where the battery is on fire, if it is safe to do so, disconnect the battery pack by turning of the circuit breaker to shut off the power to the system. Use FM-200 or Co2 fire extinguisher for the battery and an ABC fire extinguisher for the other parts of the system. Under any fire situation, please evacuate the people from the building immediately before trying to extinguish it. Water Situation The battery modules are not water resistant.

7. Installation 7.1 Items in the package Please check if following items are including with the package: For Mira-HV25 A B C Quick Installation Guide D Number A B C D Items Communication cable (0.21m) Battery power cable (0.19m) Fixing bracket Grounding cable (0.19m) E Number E F G F G Items Mounting screw pack Installation guide User Manual Note: item C is provide separately, not including in battery package. Please contact your dealer if you do not have it.
Note: item F is provide separately, not including in battery package. Please contact your dealer if you do not have it. 7.2 Clearance Make sure to leave a space of at least 300 mm. A clearance of at least 300 mm must be Ieft around the battery pack for proper cooling. Note: Make sure that the battery pack is always exposed to the ambient air. The battery pack is cooled by natural convection. If the battery pack is entirely or partially covered or shielded, it may cause the battery pack to stop operating.
7.4 Installation Steps Step 1: Place the front bracket and back bracket as shown below. Step 2: Insert the battery module into the bracket from front horizontally, and tighten the four screws on the side. Step 3: Locate the brackets for the second battery on top of the first pair of the bracket and fasten the connecting button on the side. Step 4: Insert the battery module into the bracket from front horizontally, and tighten the four screws on the side.
Step 5: Connect the inverter as shown in the figure below. Note: If the Battery modules are more than 4 pieces, please separate into multiple stacks. Please make sure each stack only including max. 1 BMS and 4 battery modules.
7.5 Wiring Steps A. Battery power cable Step 1: Connect the power cable starting from the first battery module in series with other battery modules (Orange opposite, black negative). A ‘click’ sound indicates the connections are secured. The positive and negative connection of the battery cable is shown in below. Step 2: Measure voltage value: After all battery modules are connected in series, use a multimeter to measure the DC voltage on DC terminal.
ADDR CAN-1 CAN-2 C. Grounding cable: Connect the grounding cable to ensure that all batteries are grounded. Wiring shall be connected in the sequence as shown in below.
7.6 System Start up · · · 1. · 2. · When the grid connected system is started, the inverter should be turned on first to avoid the current pulse of the inverter increasing to the battery pack. All installation and operation must comply with local electrical standards. Check all power cables and communication cables carefully. Turn on the POWER switch After powering on, all the green lights flash once, and then the running water lights flash once.
8. Commissioning There are two LED indicators on the front of the battery packs to show its operating status. For Mira-HV25 Green LED Red LED Batteries Status On for 0.5s, Off for 0.5s On for 0.5s, Off for 0.5s Runing in boot On for 0.1s, Off for 0.1s On for 0.1s, Off for 0.
