Frequently Asked Questions

  • Are Lithium Iron Phosphate (LiFePO4) batteries worth the investment?

    Yes, energy storage systems implementing LiFePO4 cell technology can offer users a return on investment within the cycle life of the battery. While they may have a higher upfront cost compared to other battery technologies such as lead acid, they are worth the investment because they offer a longer lifespan and can be discharged to a much higher depth. For example, a 5kWh battery charged by renewable methods and discharged 6000 times to 90% DOD will provide 27MWh of stored energy.

  • Why are Lithium Iron Phosphate (LiFePO4) batteries better than other energy storage options in the market?

    Traditional Lead Acid batteries require regular maintenance and can only be discharged to ~50% of their capacity, and typically do not last as long as LiFePO4. LiFePO4 energy storage systems have built in Battery Management Systems which protect the cells and do not require any maintenance, and some may be discharged to up to 90% of their capacity for greater utilization. By choosing LiFePO4, one can expect high efficiency, high energy density, long lifespan, high depth of discharge, no maintenance, and a fast charge rate. Compared to other lithium chemistries, LiFePO4 is safer: it is much less flammable and reaches thermal runaway at a higher temperature than others.

  • What is the expected lifespan of Lithium Iron Phosphate (LiFePO4) energy storage solutions?

    Most LiFePO4 batteries can be expected to last between 5-10 years while still remaining within the manufacturer’s warranty. LiFePO4 batteries which are used conservatively and kept in ideal conditions could last 10+ years.

  • Why is Lithium Iron Phosphate (LiFePO4) energy storage a good fit for solar applications?

    LiFePO4 storage systems are the safest chemistry for residential and commercial energy storage and have a high cycle life, meaning they are ideal for battery-based PV systems which are expected to experience daily SOC cycling, and the occasional period of autonomy when the sun is not available.

  • What benefits does a Lithium Iron Phosphate (LiFePO4) battery solution offer to a home or small business?

    LiFePO4 energy storage can offer a long-term return on investment by reducing/eliminating a home or business owner’s reliance on the public utility, or by providing peace of mind by offering a back-up power system in case of blackouts.

  • What is Lithium Iron Phosphate (LiFePO4) energy storage?

    Lithium Iron Phosphate (LiFePO4) is one of many types of lithium cell chemistries used to build energy storage systems (ESS). Implementations of LiFePO4 for energy storage can range from a portable battery in a cell phone or handheld device to a stationary battery pack used to provide power to homes, RVs, businesses, or micro-grids.

  • What is Lithium Iron Phosphate (LiFePO4)?

    LiFePO4 is the chemical compound formula for Lithium Iron Phosphate, which is a specific lithium cell chemistry used in energy storage systems.

  • What are the best guidelines for Depth of Discharge with lithium energy storage?

    Setting a DOD lower than the manufacturer’s absolute maximum limit will mean a longer lifetime for your battery. If you would like to extend the lifetime of your battery well beyond the manufacturer’s warranty, implement more energy storage capacity than you need on a daily basis so that the daily DOD requirement is low.

  • What is DOD or Depth of Discharge?

    DOD is the percent of capacity you allow an ESS to discharge in one cycle from a full state of charge (SOC). For example, a 75% DOD means that a battery may be discharged to 25% of its total full capacity. DOD = 100 – SOC at end of charge.

  • Will Lithium Iron Phosphate (LiFePO4) batteries degrade over time?

    All batteries, no matter the cell type or chemistry, will degrade over time. Excessively high or low temperatures or voltages, and excessively high rates of charge or discharge will increase the degradation of a battery (measured as State of Health, the ratio of original capacity to current usable capacity). On the contrary, using conservative voltage and current limits as well as keeping the ambient temperature moderate can help extend the lifetime of any battery cell.

  • What does LFP stand for?

    LFP stands for Lithium Iron Phosphate, whose chemical formula is LiFePO4. A LiFePO4 battery is a specific type of cobalt-free lithium-ion battery which uses LiFePO4 as the cathode material.
