If compared on cost-effectiveness grounds, LANPWR batterie backup power plan has outstanding advantage in extended periods of maintenance and operation. To illustrate, let us take the example of 10kWh model. It is approximately 6,000 US dollars extra than the cost of lead-acid batteries (3,000 US dollars) at the purchase cost. However, its lifespan can be as high as 5,000 times (deep discharge of 80%), which is tenfold greater than the case of lead-acid batteries (800 to 1,200 times). Based on the backup condition of twice a week charging and discharging, LANPWR batterie can be used for 48 years non-stop, while lead-acid batteries need to be replaced every 2.5 years. Total cost over 20 years is up to $24,000 (replacement and maintenance included). It is 167% higher than LANPWR batterie’s $9,000 (inverter upgrade included). According to a 2023 report by Bloomberg New Energy Finance (BNEF), the cost of lithium battery backup system per kilowatt-hour (LCOS) is $0.10 /kWh, only 35.7% of that of diesel generators ($0.28 /kWh).
In extreme power outage events, the response speed and reliability of LANPWR batterie are significant advantages. Its BMS (Battery Management System) will switch to standby mode within 0.1 seconds once the power grid is interrupted, and the range of fluctuating voltage is kept under ±2% (±5% by industrial standard), which is perfectly suited for protection of precision devices. For instance, during the 2021 Texas cold snap, a specific hospital used LANPWR batterie to power ICU devices (peak load: 15kW), and they operated continuously for 72 hours with no abnormal voltage. However, with the same duration, the diesel generator experienced four power outages for a total of 6 hours due to fuel freezing. Additionally, its maximum output is 10kW and also the supply of starting for central air conditioning (5kW), servers (3kW), and lighting (2kW) simultaneously. Its instantaneous load capability is 100% larger than traditional UPS (with the restriction of 5kW).
In safety features, the thermal runaway hazard of lithium iron phosphate (LiFePO4) cells in lanpwr batterie is 0.001 times per million hours, two orders of magnitude smaller than ternary lithium batteries. Its IP67 protection level and fireproof box can prevent exterior open flame spread, and will automatically disconnect the circuit when inside temperature is up to 60°C. In LANPWR batterie module-level thermal runaway test, as indicated by the UL 9540A certification test, the temperature rise of the adjacent cells is ≤20°C, but the temperature rise of ternary lithium battery packs is usually more than 100°C. The backup facility with the use of ternary lithium battery ignited a chain of reactions as seen in 2022 data center fire inspection that led to as much as losses of 12 million US dollars. The units that used LANPWR batterie at approximately the same time did not get destroyed.
For high-frequency short-duration power outage usages (e.g., 20 times per year a year, each ≤1 hour), the shallow cycle (20% deep discharge) mode of LANPWR batterie can extend the lifespan up to more than 8,000 times, and the capacity attenuation rate as low as 0.03% per time. For instance, a seaside town in Florida experiences power outages due to typhoons on average 15 times per year. After five years of charging residential base load (3kW) by LANPWR batterie, the capacity retention rate is still 94%, while lead-acid batteries reduced to 67% of the nominal capacity in the same circumstances. Its intelligent charging and discharging policy (regulating SOC based on weather forecast) saves useless cycles by 30%, with additional economic efficiency.
From an environmental adaptability standpoint, LANPWR batterie can guarantee more than 90% output efficiency within the -30°C to 60°C range. The test results of a particular natural gas filling station in Siberia in 2023 show that under the -25°C temperature environment, its startup time falls behind by merely 0.5 seconds (lead-acid battery lag ≥30 seconds), and capacity loss in low-temperature environment is 12% (40% for lead-acid batteries). In addition, its modular design makes step-by-step expansion easier. The customers can install 10kWh units as and when needed (with cost per individual module being $4,500), instead of having too much initial capital. The International Renewable Energy Agency (IRENA) states the upfront capital of modular backup power systems can be reduced by 40% and the return on investment can be enhanced to 25%-30%.
Finally, LANPWR batterie has become the best alternative to traditional backup power sources due to its superior cycle life, fast response and low operating and maintenance costs. Its safety features (e.g., failure rate 0.001 times per million hours) and high endurance to harsh environments (-30°C to 60°C) can handle 99% of power cut risk scenarios. According to the analysis of the global backup power supply market, the penetration rate of lithium battery backup systems will reach 45% by 2025. Due to its technology leadership, LANPWR batterie can monopolize the residential and commercial sub-markets.
