All batteries must be of the same type, size, and general age. Using an old, mismatched, or faulty battery can cause significant issues. 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 9.6/14.4KWH LFP ESS? The 9.6/14.4KWH LFP ESS uses 2x or 3x well-known PYLONTECH US5000 Lithium-Ferro-Phosphate (LFP) batteries with a total capacity of 9,600/14,400Wh in parallel. It is designed to optimise energy usage, providing a stable electricity supply while reducing costs. By harnessing free solar energy to charge the battery, this system revolutionises your energy consumption. When integrated with a private power station, such as a solar energy generation system, it enables a reliable 24/7 home power network. 2. What is the cycle life of the battery? PYLONTECH US5000 batteries are rated for 6,000+ cycles at 95% depth of discharge (DoD). 3. How can I maximise the lifespan of the battery? Regular charging: The battery must be charged at least once every six months. During this maintenance charge, ensure the State of Charge (SoC) exceeds 90%. Annual checks: After installation, inspect the power connector, grounding points, power cables, and screws annually. Ensure there are no loose connections, broken components, or signs of corrosion. Verify the installation environment is free from dust, water, and insects, and remains suitable for an IP20-rated battery system. Storage maintenance: If the battery is stored for extended periods, recharge it every six months to maintain an SoC above 90%. 4. What are the battery care and storage instructions? Storage charging: Recharge the battery every six months when stored, ensuring the SoC is at least 90%. Post-discharge recharging: Recharge the battery within 12 hours after a full discharge. Environment restrictions: Avoid installing the battery in outdoor environments or locations outside the operational temperature or humidity range specified in the manual. 5. When should I charge my PYLONTECH LIFePO4 battery? LiFePO4 batteries do not require charging after every use unless fully discharged. They are not damaged by remaining in a partial state of charge (PSOC). Charge the battery after use or when it has been discharged to 80% Depth of Discharge (DoD), leaving a 20% SoC. 6. What should I do if the battery bank loses power too quickly? Check Appliance Power: Verify whether high-power electrical appliances are connected. For example, with a 9.6kWh or 14.4kWh Off-Grid Energy Storage System, if a connected appliance consumes approximately 2,000W, the battery will last about 4.3 hours (9.6kWh) or 6.5 hours (14.4kWh) when discharged from 100% to 10%. DC TO AC INVERTER 1. What does a power inverter do? A power inverter converts battery power into mains electricity. Specifically, it transforms 48V direct current (DC) into 230V alternating current (AC). This 230V AC matches the electricity supplied by utility companies and is suitable for household appliances like lights, televisions, and refrigerators. In the 9.6/14.4KWH LFP ESS RIIO SUN II Off-Grid Hybrid 5000W 48V Pure Sine Wave Inverter/Charger is used to create a home 230V "grid". 2. What type of inverter is used in the 9.6/14.4kWh LFP ESS? The system uses a pure sine wave inverter rated at 5000W. This inverter outputs a smooth, harmonic sine wave resembling utility-supplied power. It seamlessly switches polarity ("+" and "-") between power cables and adjusts voltage gradually to meet demand. This inverter design ensures compatibility with a wide range of appliances. 3. What are the key functions of the RIIO SUN II 5000W 48V off-grid hybrid inverter? 5000W 48V Pure Sine Wave Inverter: Converts DC to 230V AC to power household appliances, including TVs, laptops, refrigerators, and lights. It delivers 5000VA continuous power with a peak capacity of 10,000VA for high-starting power appliances. Built-in MPPT solar charge controller: Equipped with two independent 4,400W inputs, it charges batteries at up to 50A with safety features like overcharge and overheating protection. Advanced MPPT technology ensures 98% efficiency. Enhanced 60A smart battery charger: Supports fast, efficient charging from a mains power source or generator, with overcharge protection and multi-stage charging. Scalability: Supports parallel connection of up to three additional inverters for expanded capacity (up to 15kW) and optional three-phase operation for industrial-grade equipment. 4. What are the additional intelligent functions of the RIIO SUN II 5000W 48V hybrid inverter? Automatic generator start (AGS): Activates a generator only when necessary for optimal energy use. Power assist and control: Allows a small generator to handle heavy loads by supplementing power as needed. User-friendly monitoring: Features the Nova Web and mobile app via the TBB-KIN2 Kinergy-II Wi-Fi module for remote monitoring and control. Reliable operation: A fast 4ms switch ensures uninterrupted power during outages. ECO mode maximises battery backup time with low energy consumption. High efficiency: Achieves 94% inverter efficiency and 98% MPPT efficiency, maximising energy output. Ease of use: The all-in-one design simplifies installation and maintenance. It auto-restarts when PV or AC power is restored, ensuring seamless operation. 5. What can I use the RIIO SUN II 5000W 48V hybrid inverter for? The inverter is designed to support standard household appliances. See the table below for typical power consumption and corresponding battery usage times.

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. Why are a 48V battery bank and a 48V DC to 230V AC inverter used in this system? This configuration offers several key advantages: The inverter’s input current is two to four times smaller at 24V compared to 12V, improving system safety and reliability. The cables connecting the battery to the inverter can be thinner than those required for a 12V system, reducing material and installation costs. 7. What AC inputs/outputs does the 5000W inverter have? 1 x 230VAC input and 1 X 230VAC output. 8. Does the 5000W inverter support wireless control? This inverter can be set up to send data to an online user portal via a NOVA WEB & APP. 9. What to do if the 5000W inverter cannot power electrical appliances? Check whether the inverter’s 5000W output power is sufficient for your appliance’s requirements. If a warning indicator appears, refer to the User Manual for specific troubleshooting steps. 10. What to do if appliance usage time is too short? Due to variations in appliance power consumption, the inverter’s discharge efficiency is slightly below 100% (typically around 98%). This means actual usage times may be shorter than theoretical calculations. To determine usage times: Base calculations on the continuous power rating of your appliances.
