This guide is intended to be used as a supplement to all manuals and documentation provided by device manufacturers. In case of discrepancies or conflicts, contact Solar MD Technical Support immediately.

• Only qualified personnel should work on electrical equipment.
• Wear necessary PPE when working with electricity.
• Read and follow all device manuals.
• Refer to the SolarMD Quick User Guide for communication cable termination.
• Electrical wiring must comply with local standards.
• Ensure mechanical and electrical integrity:
  1. Earth resistance test and bonding continuity
  2. Polarity test
  3. Torque and mark all bolts and terminations
  4. AC cable insulation testing
  5. DC bus insulation testing (see SMD_IRT-DCB_01)

• Visually inspect for safety: covers in place, no live parts accessible.
• Turn on all batteries using the green ON/OFF switch on the BMU.
• On MyPower24 portal:
  1. Go to Logger > Interfaces tab → press Scan → connect found battery.
  2. In Battery > Settings:
     • Set Cluster Remote Device to InPower
     • Set CANBUS Baudrate to 250kbps
  3. In Battery > Cluster Data:
     • Identify the Master battery
     • Confirm “Online Batteries” = number of installed batteries
  4. In Battery > Actual Data:
     • Confirm all battery voltages are within 10V of each other

• Turn on battery isolators → wait ~5s for precharge and main relay
• Confirm in Battery > Cluster Data: “DC BUS Connected Batteries” = installed batteries
• Power on:
  1. External DC switch (if present)
  2. Grid breaker on PCS (PCS should start in ~1 min)

• On MyPower24 portal:
  1. In Logger > Interfaces tab:
     • Select eth0
     • Click Add Device → select InPower
     • Enter serial number, IP, etc. → click Start
     • Blue balloon should appear in My Devices
  2. In PCS page:
     • Set battery type to Lithium-ion

!! IMPORTANT: Incorrect battery type may cause damage and void warranty.

• Configure grid settings per local code

1. In Battery > Cluster Data:

• Check:
  1. Can State = Enabled
  2. Line State = Connected
  3. Bit Rate = 250kbps
  4. Tx/Rx frames increase every ~3 seconds
  5. Note: If baud rate is changed, restart PCS to reset CANBUS controller

• Once communication is confirmed, switch PCS on for testing
• Start PCS:
  1. Off-grid: no load
  2. Grid-tied: low charge/discharge power
• Verify AC/DC voltage and current match portal data
• Check for proper function of batteries, PCS, and other devices
• Disconnect CANBUS temporarily:
  1. PCS should show BMS Communication Fault in ~10s
  2. Reconnect → PCS should recover in ~3s

• Perform high current test:
  1. In Battery > Remote Device Control Test:
     • Set charge/discharge current to 0A for 20s
     • Battery current should drop to 0A and recover automatically
  2. Ensure:
     • Battery room is climate-controlled (20°C–30°C)
     • PCS has adequate cooling
     • Use thermal camera to verify no overloaded cables or loose connections
