Installation SoFar PowerAll All-in-one ESS energy storage system

Installing the Sofar PowerAll energy storage system is straightforward thanks to its modular, plug-and-play design. Each battery module weighs approximately 50 kg and stacks vertically beneath the inverter module.

Step-by-Step Installation Guide

Step 1: Site Preparation

• Choose a well-ventilated, dry, and non-flammable indoor location.
• The floor must be flat and level, with no risk of water ingress.
• Ensure at least 300 mm clearance on each side, and 600 mm front clearance.
• Check ambient temperature (−25 °C to +60 °C supported, optimum: 15–30 °C).

Step 2: Wall Mount the Inverter

• Use the included metal mounting bracket to mark drill points.
• Securely attach the hybrid inverter to the wall using expansion bolts.
• Leave adequate clearance below for stacking battery modules.

Step 3: Place the Battery Base & Stack Modules

• Position the battery base plate directly beneath the inverter.
• Gently lower the first BTS5K battery onto the plate, aligning locking pins.
• Stack additional modules (up to 6) vertically.
• The battery system supports tool-free mechanical stacking.

Step 4: Connect Communication & Power Cables

• Use the CAN/RS485 communication cables provided to link the inverter and batteries.
• Connect positive (+) and negative (–) power cables between modules using torque-controlled tightening (≥ 10 Nm).
• Connect the battery grounding terminal to earth.

Step 5: Connect External AC/DC Wiring

• Connect the PV input strings to the inverter’s DC terminals (up to 600 V DC input).
• Wire the AC grid input, critical load output, and optional EPS (emergency power supply) if needed.
• Use proper breakers, surge protection, and follow local wiring codes (e.g., AS/NZS 3000).

Step 6: Final Checks & Commissioning

• Double-check all mechanical stacking points and cable torque.
• Power on the inverter and battery system using the single power button.
• Set up system parameters using the LCD display or Bluetooth Smart App.
• If connected to Wi-Fi or Ethernet, register the system on the SOFAR monitoring platform for remote performance tracking.
