Which battery is suitable for photovoltaic storage?

Lithium batteries for photovoltaic storage. Modular system with 5 kWh stackable battery packs with 100% discharge capacity. Huawei presents the lithium battery (Lithium Iron Phosphate – LFP) Huawei LUNA2000-5 / 10 / 15. This high voltage battery is compatible with a wide range of inverters on the market.

Do LFP batteries last longer than NMC batteries?

In general, LFP batteries tend to last longer than NMC because they are more resistant to high temperatures that degrade battery life. However, the lifespan of a battery also depends on how you use it. According to a 2020 study by the National Renewable Energy Laboratory (NREL):

How often should you run a solar battery?

Running too few or too many cycles can be detrimental to your battery’s lifespan. A single cycle per day is a normal rate for a household with solar panels, though if you're on one of the best export tariffs, check with your installer if it'd be more profitable to run two cycles.

How do you measure a battery's lifespan?

If you want a more accurate way of measuring a battery’s lifespan, you can track the number of total cycles it’s performed – meaning the amount of times it charges up and discharges. The best batteries can usually go through roughly 6,000 cycles in total, and most homes will typically cycle through their battery around once per day.

What happens if you leave a battery fully discharged?

It also risks causing unnecessary wear and tear to your battery, which can lead to long-term issues that ultimately end up with it breaking down prematurely. On the other hand, if you leave your battery completely discharged for too long, it’ll start to degrade.
