All‑In‑One Energy Storage System

This guide covers the essential steps to install, connect and start up the All-In-One. It does not replace the All-In-One User Manual. Read the manual's safety instructions (§1) before you start, and use the manual for any step you are unsure of. References such as §5.3 point to sections of the user manual.

Only licensed electrical workers may install the All-In-One

Install in accordance with AS/NZS 3000, AS/NZS 5139, AS/NZS 4777.1 and the requirements of the local network service provider. Never work on live equipment: isolate every supply first. Connect the protective earth before anything else, and disconnect it last.

Lithium-ion battery

The cabinet holds up to 112.5 kWh of lithium-ion batteries at high DC voltage (up to 840 V). Never short-circuit the battery terminals. Do not install, wire or open the cabinet in rain, snow, lightning or high humidity.

1.1What You Need

• The All-In-One: the battery cabinet (Solinteg E2BR) and the hybrid inverter (Solinteg M2HT 25–50 kW), which is packed separately.
• Supplied in the cabinet's parts box: decorative panels, mounting feet, lifting eyes, rain shelter, cable covers, bolts, M20 × 150 expansion anchors, lugs, the communication module, the battery communication cable and the inverter emergency stop cable (full list §3.4).
• You supply: grid, load and earth cables, earthing flat bar if used, cable tray and sealing material (§5.1.2).
• Lifting: a crane or forklift rated for at least 2 t, operated by a holder of the required high risk work licence.
• Tools: hammer drill, torque wrench and sockets, crimping tools (including RJ45), wire strippers, screwdrivers and a multimeter with a DC range above 1100 V (§4.1.5, §5.1.1).

2.1Choose the Site

• A concrete, solid-brick or steel foundation designed for at least 2 t, level within 3 mm and sloping no more than 5°, with cable trenches or conduit entries (§4.1.2).
• Well drained and not low-lying, away from heat, flammable materials, corrosive gases, dust and strong vibration. Keep the separations from buildings that local fire codes require (§4.1.3).
• Keep the clearances shown below around the cabinet.

2.2Lift and Place the Cabinet

1. Unpack the crate and remove the pallet bolts (§3.1). The door key is on the side cable panel.
2. To lift by crane, screw the four M24 lifting eyes and rubber washers into the top of the cabinet. Otherwise, use the forklift pockets (§3.2).
3. Place the cabinet on the foundation. Keep it upright and tilted no more than 10°.

2.3Anchor the Cabinet and Fit the Inverter

1. Fit the decorative panels with the 24 M5 × 10 screws (§4.2.1).
2. Choose front-and-rear or left-and-right mounting feet, and mark out the holes.
3. Drill the holes (25 mm, 150 mm deep), vacuum them clean and tap in the M20 × 150 anchors.
4. Bolt the four feet to the cabinet with the M8 × 25 bolts, then tighten everything evenly.
5. Fit the rain shelter above the right-hand side with the five M6 × 16 bolts and waterproof washers (§4.2.2).
6. Fix the inverter bracket to the right-hand side with four M8 × 16 bolts, hang the inverter on it and tighten the M6 side screws (§4.2.3).

Before you connect anything

Switch off every breaker in the cabinet and turn the inverter DC switch OFF. Connect the cabinet earth first. Leave the waterproof plugs in unused cable entries, and seal every entry when you finish.

3.1Earth the Cabinet

Connect the earth point on the right of the cabinet to the site earthing system with 40 × 4 mm galvanised flat bar or 50 mm² PE cable, using two M8 × 16 bolts at 8 N·m. Paint cut ends of the flat bar (§5.2).

3.2Inverter AC Cables (On-Grid and Back-Up)

The cables from the cabinet to the inverter are supplied and already connected inside the cabinet. Loosen the glands on the side cable panel and pull each cable out far enough to reach the inverter.

• On-grid: fit the connector seal parts to suit the cable, then the L1/L2/L3 lugs and N/PE lugs at 3.8 N·m. Tighten the connector nut to 10 N·m (§5.3.1).
• Back-up: do not confuse the back-up connector with the generator connector. Strip 95–100 mm of sheath and 15 mm of each core, tighten the terminal screws to 5 N·m and the nut to 10 N·m (§5.3.1).
• Feed any excess cable back into the cabinet and tighten the gland nuts.

3.3Battery DC Cables

1. Measure the battery voltage at the cable ends. It must be 840 V or less. Check the polarity.
2. Plug the positive and negative connectors into the inverter battery terminals until they click.
3. Inside the cabinet, remove the battery pack cover at the upper left. Plug the main positive and negative cables into the battery pack until they click, then refit the cover (§5.3.2).

3.4Communication and Emergency Stop

• BMS communication: run the supplied cable from communication port B on the side cable panel to the inverter's BMS 1 port (COM3, RJ45). BMS 2 is not used. Pinout: §5.3.1.
• Emergency stop: run the supplied cable from port C on the side cable panel to the inverter COM2 push-in terminals, following the COM2 terminal definitions in the inverter manual.
• PV: connect the PV strings to the inverter as its manual describes, using 4 mm² or 6 mm² cable.
• Fire alarm signal (optional): a dry contact on terminals 1-A and 2-A, for remote fire monitoring (§5.3.4).

3.5Grid and Load Cables

1. Remove the sealing plate under the electrical compartment and open the grid and load glands in the base.
2. Thread the cables through the glands. Strip 95–100 mm of sheath and 20–25 mm of each core.
3. Crimp the lugs: SC50-8 on the grid cores (12 N·m), C45-25 on the load cores (3.5 N·m) and SC16-8 on PE (12 N·m).
4. Connect L1, L2, L3, N and PE as shown, refit the lower cover and tighten and seal the glands (§5.3.3).

3.6Finish

Tie the cables to the tie bar and fit the cable cover after commissioning (§5.3.1). Close and lock the cabinet door.
