Battery Bank

Warning:

Never mix batteries within the battery bank. All batteries must be of the same type, size, and general age. Using an old, mismatched, or faulty battery can cause significant issues and damage to the equipment.

Note: New batteries behave like older ones initially and require a few cycles to function optimally.

1. What is the battery bank capacity of the 4.2/5.5kWh AGM ESS?

The 4.2/5.5kWh AGM ESS employs four reliable AVON ADC12-EV175 12V or AVON ADC12-EV230 12V deep cycle AGM-GEL batteries, providing a total capacity of 4,200/5,500Wh (4x 175/230Ah (C20) @12V in series). These maintenance-free VRLA batteries require no water or acid during operation. With patented structural designs and nano silica gel technology, they offer 5–10% higher capacity and improved active material utilisation compared to similar products.

2. What is the cycle life of the battery?

The AVON ADC12-EV175 and ADC12-EV230 batteries are rated for:

• 600+ cycles at 80% depth of discharge (DoD)
• 1,200+ cycles at 50% DoD

This is 1.5 times greater than standard AGM batteries.

3. How can I maximise the lifespan of the battery?

• Temperature: Keep between 23°C and 27°C. Avoid prolonged storage above 40°C or below -15°C.
• Charging: Always fully charge AGM batteries to 100%. Regular partial charges reduce their ability to fully charge over time.
• Discharge Level: Limit discharge to 80% of capacity for optimal performance. Frequent shallow discharges prolong battery life.
• Avoid Extremes: Do not charge below 0°C or above 40°C to prevent damage.

4. What are the care and storage instructions for the battery?

• Store batteries at temperatures between -15°C and 40°C.
• Avoid placing them directly on concrete floors.
• Perform a refresher charge every 3–4 months during extended storage to prevent excessive discharge.

5. When should I charge my AGM battery?

Charge whenever the battery is not fully charged. Regularly charge unused batteries once a month to maintain capacity.

6. What if the battery bank loses power too quickly?

Check for high-power appliances connected to the system. For example, a device consuming ~1,000W would deplete a fully charged 4.2/5.5kWh battery bank (discharged to 20%) in approximately 3.4–4.4 hours.

DC to AC Inverter

1. What does a power inverter do?

A power inverter converts battery power (24V DC) into mains electricity (230V AC), enabling the use of household appliances.

2. What type of inverter is used in the 4.2/5.5kWh AGM ESS?

The system uses a 3000W Pure Sine Wave Inverter. This inverter delivers power that closely resembles grid electricity, ensuring smooth operation for sensitive appliances.

3. Key functions of the RIIO SUN II 3000W 24V Hybrid Inverter:

• 3000W Pure Sine Wave Inverter: Delivers 3,000VA continuous power and handles peak loads up to 6,000VA for devices like pumps or power tools.
• 80A MPPT Solar Charge Controller: Maximises solar output efficiency (up to 98%) and provides safety features against overcharge, overheating, and reverse current.
• 70A Smart Battery Charger: Ensures safe, unattended charging from mains or generators, with multi-stage protection.

4. Additional intelligent functions:

• Automatic Generator Start (AGS): Activates the generator as needed for efficiency.
• Power Assist & Control: Supplements generator capacity and reduces fuel consumption.
• Remote Monitoring: Manage the system via Nova Web or the TBB-KIN2 Kinergy-II Wi-Fi module.
• Fast Switching: 4ms response to power interruptions ensures reliable operation.

5. What can I use the RIIO SUN II 3000W 24V Hybrid Inverter for?

The inverter is ideal for powering standard household appliances, including TVs, laptops, fridges, microwaves, and lighting, with excellent efficiency and reliability.

Appliances marked with an asterisk (*) are likely to have a starting power consumption several times higher than their normal operating power. This is typically due to the presence of electric motors. For example, an electric lawnmower with a normal operating power of 1,000W may have a starting power of over 4,000W. An inverter with a continuous power of 3,000W is suitable in such cases because it can handle a peak power of up to 6,000W.*

**Appliances without electric motors may also have variable power consumption with occasional spikes. These spikes necessitate a larger inverter than would typically be required for devices with similar nominal power ratings.

Please note: This table is for general guidance only. The actual power consumption and starting power requirements of your appliances may vary significantly. Always check the specifications of your devices to confirm their continuous and starting power requirements.

If multiple devices are connected to the inverter, the total power consumption should be the sum of all connected appliances. This total will determine the inverter capacity required.

6. What protection and safety features does the 3,000W inverter have?

This inverter is equipped with the following protections and warning indicators:

• Overload protection
• Overcharge protection
• Battery overcharge warning
• Low battery warning
• Solar charge interruption due to low battery
• Solar charge interruption due to high PV voltage
• Thermal shutdown at 60 ± 5°C

8. What are the AC inputs and outputs of the 3,000W inverter?

• AC Input: 1 x 230V AC
• AC Output: 1 x 230V AC

9. What should I do if the 3,000W inverter cannot power electrical appliances?

• Confirm that the inverter's output power meets the power requirements of the connected appliances.
• If a warning is displayed, follow the troubleshooting steps outlined in the User Manual.

10. What should I do if an appliance's usage time is too short?

• The inverter operates at less than 100% efficiency, with the best efficiency being approximately 98%.
• Actual usage time may vary depending on the continuous power demand of the appliance.
• For an accurate calculation of usage time, contact Energian Customer Service with the specifications of your appliances.
