4. WHAT ARE THE BATTERY CARE AND STORAGE INSTRUCTIONS?

• Store batteries between -15°C and +40°C.
• Avoid placing batteries directly on concrete floors.
• Store batteries in a cool (temperatures must be above freezing) dry location unpacked or in the original packaging.
• Perform a refresher charge every 3-4 months during long storage periods to avoid excessive discharge.
• Self-discharge will occur at varying speeds depending on temperature: 4.5 months at 40°C, 9 months at 30°C, 15 months at 20°C, 23 months at 10°C. 

5. WHEN TO CHARGE MY AGM BATTERY?

• Charge AGM batteries any time they are not fully charged.
• Consult the battery manufacturer’s manual for the correct charging method.
• Charge the battery monthly during periods of disuse.

6. WHAT TO DO IF THE BATTERY BANK LOSES POWER TOO QUICKLY?

• Check for high-power electrical appliances connected to the system.
• The 8,400/11,040Wh battery capacity typically lasts about 6.7 or 8.8 hours, respectively, when powering a 1000W appliance from 100% to 20% discharge.

DC TO AC INVERTER

1. WHAT DOES A POWER INVERTER DO?

A power inverter converts battery power into mains power, changing 48V direct current (DC) into 230V alternating current (AC). This 230V AC is the standard power supplied to homes and is needed by most household appliances like lights, TVs, and fridges. There are two main types of inverters:

• Off-grid inverters: Work independently and require batteries (used in caravans, boats, or places without mains power).
• On-grid or grid-tie inverters: Need mains power to function (they are used in household solar systems, directly taking input from solar panels)

The 8.4/11.0kWh ESS uses the ICONICA 6000W 48V Hybrid Pure Sine Wave Inverter, which can create a home 230V grid.  

2. WHAT TYPE OF INVERTER IS USED IN THE 8.4/11.0KWH ESS?

The 8.4/11.0kWh ESS uses a pure sine wave inverter rated at 6000W. This inverter provides up to 6000W output in a smooth sine wave, similar to utility-supplied power. It smoothly switches polarity between power cables, which is essential for alternating current.

3. KEY FUNCTIONS OF ICONICA 6000W 48V HYBRID INVERTER:

• 6000W 48V Pure sine wave inverter: Converts DC to 230V AC to power household appliances like TVs, laptops, fridges, microwaves, and lights. It can handle continuous power up to 6000W and peak power up to 12000VA (for starting appliances with electric motors like pumps and power tools). Pure sine wave inverters are more efficient and compatible with a wider range of appliances than modified sine wave inverters.
• 120A Smart battery charger: Charges batteries safely, efficiently, and quickly (up to 120A) from mains power or a generator, with full overcharge protection and multiple charging stages.
• Uninterruptible power supply (UPS) zero transfer time: Instantly switches from mains to battery mode during power interruptions.
• System expansion: Can be connected in parallel with up to 8 additional identical inverters, offering up to 54kW/54kVA of power. This allows for a 3-phase operation for industrial-grade equipment. Each additional inverter requires a Parallel connection kit (sold separately). 
  
• 120A MPPT built-in Solar charge controller: Regulates solar panel input with up to 98% efficiency, protecting against overcharge, overheating, and reverse current.

4. ADDITIONAL INTELLIGENT FUNCTIONS OF THE ICONICA 6000W 48V HYBRID INVERTER:

• Output source priority: Users can set preferences for energy sources (solar, battery, mains, generator) based on conditions and availability.
• Battery charging priority: Users can choose to charge the battery using solar power only, a combination of solar and mains power, or mains power only.
• Customisable settings: Users can personalise parameters such as AC input range, battery type, max charging current, and more through a user-friendly interface.
• Illuminated removable LCD screen: Displays vital statistics like input/output voltage, frequency, battery voltage, load power, charge and discharge current. The screen can be positioned up to 20m away for remote monitoring (this requires additional basic RJ45 connection cable – sold separately).
• Advanced communication options: Integrated Wi-Fi and PC connection capabilities allow for detailed system information viewing, data logging, and remote monitoring. An optional Wi-Fi connection kit (sold separately) can send data to an online portal for additional features.
• USB On-the-Go function: Allows for easy upload or download of system data via USB drive.

• Auto restart function: Automatically reconnects load appliances after disconnecting due to overload or overheating once safe conditions are detected.

5. WHAT CAN I USE ICONICA 6000W 48V HYBRID INVERTER FOR?

The 6000W 48V hybrid inverter is suitable for powering typical household appliances, based on their standard power consumption.

*Appliances marked with a star have starting power consumption several times greater than their normal working power due to electric motors. For instance, an electric lawnmower may have a working power of 1000W but a starting power of over 4000W. Thus, a 6000W inverter is suitable because it can handle surges up to 12000W. 

**Variable Power Consumption Appliances: Appliances with variable power consumption and power spikes require a larger inverter. Even without electric motors, their power needs are greater than for appliances with a similar normal power rating but not characterised by variable power consumption and spikes.

General Guidance Note: This table is for general guidance only. Actual power consumption and starting power requirements of appliances may vary. Always check your equipment’s specifications for their continuous and starting power requirements.

Total Power Consumption: If multiple devices are connected to the inverter, sum their power consumption to determine the total inverter power required.

6. WHY USE A 48V BATTERY BANK AND 48V DC TO 230V AC INVERTER?

A 48V system offers important benefits:

• The input current for the inverter is four/two times smaller for 48V than for 12V or 24V, making the system safer and more reliable.
• The cables between the battery and the inverter can be thinner compared to those for a 12V or 24V system.
  

7. PROTECTION AND SAFETY FEATURES OF THE 6000W INVERTER:

The inverter has several protection features and warnings: 

• Overload protection: 3s at 150% load; 10s at 110-150% load
• Overcharge protection: 66Vdc
• Battery overcharged
• Low battery
• Overload
• Solar charge stops due to low battery
• Solar charge stops due to high PV voltage
• Thermal shutdown: 60 +/- 5°C

8. AC INPUTS/OUTPUTS OF THE 6000W INVERTER?

1 x 230VAC INPUT / 1 X 230VAC OUTPUT.

7. DOES THE 6000W POWER INVERTER HAVE WIRELESS CONTROL?

Yes, as an option. The inverter comes with a PC connection cable and software for viewing system information like solar/battery/AC voltage, charging current, and battery capacity. Detailed data logs can be viewed and exported to PDF/Excel. The inverter can send data to an online portal using a Wi-Fi Remote Monitoring Kit (sold separately), allowing access to features like email status updates and remote monitoring.

9. WHAT TO DO IF 6000W INVERTER CANNOT POWER ELECTRICAL APPLIANCES?

First, check if the 6000W inverter’s output power meets your appliances' requirements. If there’s a warning, follow the User Manual’s instructions.

10. WHAT TO DO IF THE USAGE TIME OF AN ELECTRICAL APPLIANCE IS TOO SHORT?
If different appliances have different power requirements, the inverter’s discharge efficiency will be less than 100% (around 95%). Thus, actual usage time may be shorter than theoretical time. You can calculate discharge efficiency based on your appliances' continuous power. If you have questions, contact Energian Customer Service with your appliance specifications for assistance.
