THE BATTERY BANK

WARNING: Never mix and match batteries in the battery bank. All batteries must be the same type, size, and general age. An old, mismatched, or shorted battery in a bank causes a lot of problems. NOTE: New batteries act like old batteries and will need a few cycles before they operate correctly.

1. WHAT IS THE BATTERY BANK CAPACITY OF 4.2/5.5KWH ESS?

The 4.2/5.5kWh ESS uses four well-known, dependable AVON ADC12-EV175 or ADC12-EV230 12V deep cycle combined AGM GEL batteries with a total capacity of 4,200/5,500Wh (2x 175Ah or 2x 230Ah (C20) @12V in serial). AVON deep cycle batteries combine AGM construction with nano silica gel which provides an improvement in overall performance. Maintenance Free VRLA battery, no need to add water or acid during application. Patented structure design with high utilisation of active material, maximum improve the utilisation rate of active material and the utilisation ratio of battery internal space, 5%-10% higher capacity than similar products in the market. High performance for large current discharge.

2. WHAT IS THE CYCLE LIFE OF THE BATTERY?

AVON ADC12  battery is designed for >600 cycles @80% DoD (Depth of Discharge) and >1200 cycles @50% DoD. This is 1.5 times more than other standard AGM batteries.

3. HOW CAN I GET THE LONGEST LIFESPAN FROM THE BATTERY?

1. Keep it within 23°C -  27°C and away from water and heat.
2. For safety reasons, do not store the AVON ADC12 batteries above 40°C or below −15°C for extended periods.
3. All AGM batteries have to be fully charged to 100% percent in order to maintain their capacity. When you partially charge AGM batteries, they with time lose their capability to charge to full capacity. If you constantly charge your AGM battery to only 60% for instance, it may eventually fail to charge past 60%. This, in turn, reduces the lifespan of the battery. Lead acid batteries can get damaged if you charge them in temperatures below 0° and above 40°. AGM batteries use lead acid, therefore, you should avoid charging them when it is too cold or too hot. Preferably, charge the batteries when the temperature range is between 0° to 40° Celsius to increase their lifespan.
4. AVON ADC12 batteries can be discharged up to 100% of their capacity. However, to optimise the performance of your AVON battery, to achieve a higher life cycle, we recommend limiting the discharge not more than 80%. The general principle is that the less the battery is discharged before recharging, the greater number of charge-discharge cycles it will have in its lifetime. For example, a battery which is regularly discharged by 80% (only 20% charge remaining) will have a much shorter lifespan compared to a battery which is discharged by only 30% (with 70% charge remaining). Completely draining a battery might permanently reduce the total capacity. Some batteries (such as deep cycle) can tolerate this better, but it is still not healthy for them. Our advice is not to discharge your battery excessively and to recharge it as soon as possible, not leaving it discharged for a long time.

4. WHAT ARE THE BATTERY CARE AND STORAGE INSTRUCTIONS?

1. Recommended storage temperature: from -15°C to +40°C. Self discharge vs Time @ various storage temperature: Remaining capacity 50% - 4.5 months @ 40°C, 9 months @ 30°C, 15 months @ 20°C, 23 months @ 10°C.
2. AGM batteries should be stored in a cool (above freezing), dry location unpackaged or in the original packaging. Avoid placing the batteries directly on concrete floors. When an AGM battery is stored for extended periods, a refresher or boost charge should be performed to avoid excessive discharge and possible freezing in very cold temperatures. A refresher charge every 3-4 months is ideal. 

5. WHEN TO CHARGE MY AGM BATTERY?

Most AGM batteries can be safely charged at any time, as long as they are not already fully charged. However, it is always a good idea to consult your battery’s owner’s manual to make sure you’re using the correct charging method. It is also best to charge your dead AGM battery once a month during periods of disuse.

6. WHAT TO DO IF THE LOSS OF POWER OF THE BATTERY BANK IS TOO QUICK?
Check if there are any high-power electrical appliances connected. The Grid-backup Energy Storage System's battery capacity is 4,200/5,500Wh. Normally, if the power consumed of a connected critical electrical appliance is ~300W and the battery is discharged from 100% to 20%, the battery will run out in about 14 or 18.3 hours, respectively.

DC TO AC INVERTER

1. WHAT DOES A POWER INVERTER DO?

A power inverter is a device which converts battery power into mains power, i.e. it transforms 24V direct current (DC) into 230V alternating current (AC). 230V AC is the power supplied to our houses by utility companies, and this is the power required by most normal household appliances such as lights, TVs, fridges etc. There are two main types of inverters:

• Off-grid inverters, which work as a standalone system and require batteries (typically used in caravans, boats or locations without access to mains power)
• On-grid or grid tie inverters, which require mains power to work (typically used in household solar systems and take input directly from solar panels)

In the 4.2/5.5kWh ESS ICONICA 2000W 24V Hybrid Pure Sine Wave Inverter is used - i.e. the inverter can be used to build a home 230V "grid".  

2. WHAT TYPE OF INVERTER IS USED IN THE 4.2/5.5KWH ESS?

The type of power inverter which is used in the 4.2/5.5kWh ESS is a pure sine wave inverter rated 2000W. A pure sine wave inverter provides an output of up to 2000W which follows a sine wave harmonically. This is similar to utility-supplied grid power. This inverter switches polarity ("+" and "-") between power cables smoothly; gradually increasing or reducing the voltage as required (in case you were wondering why inverters have to switch polarity: this is the essence of alternating current; polarity changes occur approximately 50 times per second).

3. WHAT ARE THE KEY FUNCTIONS OF ICONICA 2000W 24V HYBRID INVERTER?

- 2000W 24V Pure sine wave inverter: Converts DC current into 230V AC mains electricity, to run various household appliances such as a TV, laptop, fridge, microwave, lighting etc. Able to generate 2000W of continuous power with a strong peak power handling capability of up to 4000VA (to start appliances with electric motors such as pumps, vacuum cleaners, power tools etc). This inverter is a pure sine wave type, which easily surpasses modified sine wave inverters in terms of efficiency and compatibility with a wider range of appliances.

- Enhanced 60A Smart battery charger: Designed to enable safe, efficient and fast (up to 60A) unattended charging of a battery from a mains power source or generator, with full overcharge protection and multiple charging stages.

- UPS zero transfer time: Offers instant 0ms transfer from mains to battery mode when mains power is interrupted (normal speed of transfer for other inverters is 15-20ms). This improved UPS functionality allows critical IT loads such as computers and servers to operate continuously in case of power failures.

- Inbuilt 80A MPPT Solar charge controller for further solar panel installation, if you decide to do it: The high-efficiency MPPT controller regulates the input from the solar panels to the batteries or to load, with a full range of safety functions including protection against overcharge, overheating, reverse current etc. The controller operates at up to 98% efficiency to extract the maximum possible power from the solar array.

4. WHAT ARE THE ADDITIONAL INTELLIGENT FUNCTIONS OF THE ICONICA 2000W 24V HYBRID INVERTER?

The Iconica 2000W 24V hybrid inverter boasts an abundance of unique features, providing enhanced functionality over standard inverters. These include:

- Output source priority: This intelligent feature allows the user to set output source preferences (solar/ battery power/ mains input or a generator) for the AC load output of the inverter. This menu includes several options for varying conditions and scenarios, e.g. which source of energy is given priority for the AC output if solar power is insufficient/ if the battery voltage is too low/ if mains power is unavailable, etc.

- Battery charging priority: A wide selection of battery charging priority options are available. For instance, the user can choose to charge the battery using solar power only/ using a combination of solar power and mains power/ from mains power only etc.

- A range of highly customisable settings: The parameters for this inverter can be personalised to an exceptionally specific degree via the user-friendly interface. At the touch of a button, the user can customise parameters such as the AC input range, battery type, max charging current, specific high/low voltage disconnect points (and preferred charging source upon reconnection), the duration and voltage of each charging stage, auto-restart options, power saving mode, overload bypass, battery equalisation stage characteristics and so on. There are also options for managing operational features such as the audible alarm and backlight settings.

- Illuminated LCD screen: Displays vital statistics which are easily changeable by use of the up/down keys. This information includes status and mode, input/output voltage, frequency, battery voltage, load power and percentages, charge and discharge current etc.

- Auto restart function: When overload or overheating occurs, the inverter will disconnect the load appliances, and automatically reconnect once safe conditions are detected.

- Generator auto-start function: If connected to a generator via dry contacts, the Iconica inverter can send a signal to automatically start the generator as soon as the battery voltage drops below a certain level.

- Intelligent cooling design: The inverter uses predictive fan logic based on performance and temperature (1 or 2 fans operating at a time, with variable speeds) to prevent overheating of the components. 

5. WHAT CAN I USE ICONICA 2000W 24V HYBRID INVERTER FOR?

The 2000W 24V hybrid inverter is chosen based on the typical power consumption of standard household appliances shown in the table below.

*Appliances marked with a star are likely to have a starting power consumption several times greater than their normal working power (typically this is caused by electric motors). For example, even though electric lawnmowers have a normal working power of 1000W, their starting power is over 4000W. This means that an inverter with a continuous power of 3000W is suitable because its surge power is limited to 6000W. 

**These appliances do not have an electric motor inside but still have a variable power consumption with power spikes. Therefore they require a larger inverter than would be needed for other appliances with a similar nominal power rating.

Please also note: this table is provided for general guidance only. The actual power consumption of your appliances, as well as starting power requirements, may vary considerably. In all cases, you will need to check the specifications of your equipment to find their continuous and starting power requirements.

If more than one device is connected to the inverter, the total power consumption should be the sum of all appliances used. This will determine the total inverter power required.

6. WHY IS A 24V BATTERY BANK AND 24V DC TO 230V AC INVERTER USED?

This setup will provide some important benefits:

• The input current for the inverter will be two times smaller for 24V than for 12V, making the inverter and the entire system safer and more reliable;
• The cables between your battery and the inverter do not have to be as thick as those used for a 12V battery bank and inverter.

7. WHAT PROTECTION AND SAFETY FEATURES DOES HAVE THE 2000W INVERTER?

This product comes with protections and important warning indicators, such as: 

• Overload protection: 3s @ 150% load; 10s @ 110 - 150% load
• Overcharge protection
• 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. WHAT AC INPUTS/OUTPUTS HAVE THE 2000W INVERTER?

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

9. WHAT TO DO IF 2000W INVERTER CANNOT POWER ELECTRICAL APPLIANCES?

1. First, please check whether the output power of the 2000W inverter can meet the charging power requirements of your appliances.
2. In case of a warning, take action as described in the User Manual.

10. WHAT TO DO IF THE USAGE TIME OF AN ELECTRICAL APPLIANCE IS TOO SHORT?
As the power of each electrical appliance is different, the discharge efficiency of the 2000W inverter is less than 100% (the best efficiency is about 93%). Hence, the actual usage time of electrical appliances may be shorter than the theoretical time. The discharge efficiency should be calculated based on the continuous power of your appliances. If you have any questions, please provide the specifications of your appliances to Energian Customer Service for a calculation.
