- Wear suitable personal protective equipment (PPE) during installation and operation.
- If you need a ladder, use a timber or insulated ladder.
- Before you operate the cabinet, make sure it is securely anchored. The cabinet has a high centre of gravity and can tip over, causing injury and damage.
- Some parts of the equipment can exceed 60 °C during operation. Keep away from vents, the cooling system and other hot surfaces.
- Install the equipment where children and animals cannot reach it.
- Do not use the backup supply of this equipment for:
  - life-support or other medical equipment
  - equipment or precision instruments that may malfunction or be damaged by a power failure or fluctuation.

### 1.3 Electrical Safety

- Operate the equipment strictly in accordance with this manual.
- Make all electrical connections in accordance with local regulations. In Australia, comply with AS/NZS 3000, AS/NZS 5139, AS/NZS 4777.1 and the requirements of the local network service provider.
- Isolate the power supply before you install the equipment. Never work on live equipment.
- Connect the protective earth before anything else. When removing the equipment, disconnect the protective earth last.
- Select cables in accordance with local regulations and this manual.
- Connect cables securely and tighten terminal screws to the specified torque.
- A damaged cable must be replaced by a qualified person.
- Isolate the power supply before connecting power and communication cables.
- Do not open the internal covers of the cabinet. Except for the terminal wiring described in this manual, opening covers or replacing internal components may cause injury or damage and will void the warranty.
- Before working on the battery terminals, open the battery circuit breaker or isolator. The battery is at high voltage.

### 1.4 Installation Requirements

- Before installation, check that all parts, tools and materials are present. After installation, count them again to make sure nothing has been left inside the equipment. Install every part (except optional parts) as this manual requires.
- Do not drill holes in the equipment. Drilling can damage it and affect its performance.
- Install the equipment in a well-ventilated area away from other heat sources, so the cooling system can work properly.
- Keep the vents and heat-dissipation paths clear at all times. Heat build-up can damage the equipment or cause a fire.
- Do not open the cabinet door in rain or high humidity. If you must, protect the inside of the cabinet from water.
- Never install or operate the equipment where there is flammable or explosive gas or smoke.
- Do not install the equipment in a low-lying area. Keep it away from drains, air-conditioner outlets, vents and anywhere water may leak, so that liquid cannot enter the equipment.

### 1.5 Battery Safety

- Check battery polarity carefully. Never short-circuit the positive and negative terminals. A short circuit produces very high current and heat, and can cause leakage, smoke, flammable gas, thermal runaway, fire or explosion.
- Never work on the battery while it is energised.
- Never stand or lean on the battery, or allow people or equipment to press against it.
- Do not expose the battery to high temperature or humidity. Keep ventilation and heat dissipation unobstructed.
- Never disassemble, modify, shake, drop, strike, crush or puncture the battery, or subject it to pressure shock. Damage can cause leakage, smoke, flammable gas, thermal runaway, fire or explosion.
- Never weld, grind or do other hot work near the battery. Sparks or arcs can start a fire.
- Never mix battery models or brands.
- Never use second-hand or damaged batteries.
- Before working on the battery, check for any pungent or burning smell around it.
- Batteries must be handled and maintained only by qualified people wearing PPE (including goggles, rubber gloves, a respirator and protective clothing) in accordance with local requirements.
- A battery damaged by puncture, impact, crushing, external heat or overcharging can go into thermal runaway, leak, or release toxic and flammable gas. Take safety measures on site, in accordance with local requirements, to prevent fire, protect people and avoid damage.
- Install and commission the battery in accordance with local laws, regulations and standards, and provide fire-protection equipment.

- During storage and transport, keep the outer packaging intact. Place or stack batteries the right way up, as marked on the box. Never place them upside down, on their side, on end or tilted.
- Inspect the equipment regularly for loose connections, rust, corrosion and foreign objects, and fix any problem promptly. A loose screw connection causes a voltage drop that can overheat and burn the battery at high current.
- Recharge the battery promptly after it is discharged, to avoid damage from over-discharge. A battery stored for more than six months must be inspected and tested by a qualified person before use.
- Do not charge the battery when the ambient temperature is below the minimum operating temperature.
- If a battery is swollen or its case is dented or broken, stop using it immediately and contact the installer or a qualified service person to remove and replace it. Keep a damaged battery away from other equipment and from flammable and explosive materials, and keep unqualified people away.

### 2.4 Electrical System

![Single-line diagram of the electrical system.](https://www.aerl.com.au/docs/_assets/assets/images/solinteg-e2br/e2br-electrical-system.png)

**Figure 2.15** Single-line diagram of the electrical system.

- In normal operation, the system supplies the loads.
- If the cabinet fails, you can isolate it and keep the loads supplied from the grid with the bypass switch.
- If both the PV and storage system and the grid fail, the UPS keeps the high-voltage box and the cabinet lighting powered for up to 2 hours. The UPS does not supply the site loads.

## 07 Maintenance and Troubleshooting — Maintenance, fire-protection system inspection

### 7.1 Maintenance

Inspect and maintain the equipment regularly so it keeps working properly. Where the environment or operating conditions are harsh, maintain it more often. Maintenance must be carried out by qualified people.

| Item | What to check | Interval |
|---|---|---|
| Operating environment | Temperature, humidity, corrosion and dust around the equipment Ventilation, and any water around the equipment | 3 months |
| Operating status | Cabinet indicators, and alarms in the monitoring app Any unusual noise, smell or heat | 1 month |
| Cleaning | Dust inside the equipment Air-conditioner inlet and outlet are clear | 3 months |
| Enclosure | Damage to the enclosure Corrosion of structural parts | 3 months |
| Electrical connections | Cable connections are secure Components are securely mounted No signs of arcing or tracking on component surfaces | 6 months |
| Battery packs | No rattling, deformation or leaks In storage: no more than six months between top-up charges, and SOC never below 10% | 1 month |
| Fire-protection equipment | Service and replacement by qualified people to local fire requirements | As required locally |
| Cables | If a cable at the side cable panel is damaged, have it replaced by a qualified person with cable to the specification in section 5.1.2 | As required |

#### Paint repair

The cabinet paint may be damaged by knocks during handling, transport and installation. Repair it as follows.

1. Choose a paint or touch-up spray to match the colour code. Prepare brushes, sandpaper, anhydrous ethanol, cotton cloths, masking tape and plastic sheet.
2. Mask around the damaged area with tape and plastic sheet so paint does not get on the rest of the cabinet.
3. Lightly sand the damaged area to remove rust and dirt.
4. Wipe the area with a cotton cloth dampened with anhydrous ethanol, then wipe it dry.
5. Brush or spray paint evenly over the damaged area until it is completely covered.

> **Note**
>
> If the damaged area is large, contact a professional for repair.

### 7.2 Fire-Protection System Inspection

> **Danger**
>
> Only qualified people may inspect the fire-protection system. A failed fire-protection system can cause injury, death or damage. Use proper fire-detection test equipment, so the smoke and temperature sensors are not contaminated. **Before any fire-detection test, disconnect the fire test terminal in the cabinet.** Otherwise the extinguisher will discharge and damage the equipment.

1. Lift the lever of the fire-detection quick-connect terminal at the top right of the cabinet and pull out the wire below it.
2. Following local fire-protection requirements, test the detectors with a combined smoke and heat tester until the trigger condition is reached.
3. The cabinet's audible and visual alarm should activate. If it does, the smoke and temperature detection is working.

### 7.3 Alarms and Troubleshooting

Troubleshooting must be carried out by qualified people in accordance with local requirements. Where the table says to contact AERL support, call 1800 950 865 or email support@aerl.com.au.

Codes starting with **E** are protection faults. The battery stops to protect itself. Codes starting with **I** are alarms and codes starting with **W** are warnings. The system keeps running, but the condition needs attention.

| Code | Name | Cause | Action |
|---|---|---|---|
| E400 | BMS communication | No communication between the controller and the inverter | 1. Check that the correct battery type is selected in the inverter. 2. Check the battery operating status. 3. Check the communication connection between the inverter and the BMS. 4. Check the wiring order (pinout) of the communication cable. |
| E431 | Battery voltage abnormal | The battery voltage measured by the inverter differs from the value reported by the BMS by more than 100 V | 1. Check that the power cables are connected correctly. 2. Check the power cables for leakage or damage. 3. Check for battery alarms or protection. 4. Clear the problem, then restart the battery. If it persists, contact AERL support. |
| E432 | Battery parallel number abnormal | The number of battery clusters detected in parallel differs from the configured target | 1. Check the target number. If it is wrong, correct it. 2. Check for communication faults between the batteries or clusters and the inverter. Fix them, then re-run the paralleling process. 3. Check that every cluster is powered. If not, switch on the DC breaker of each battery or cluster and re-run the paralleling process. 4. Check every cluster for alarms or protection. Clear them, then re-run the paralleling process. 5.
