In the past, the vast majority of energy storage system for house used lead-acid batteries, but in recent years, this situation began to change significantly, and more and more 48V energy storage system began to use lithium ion batteries. Today, experts in battery energy storage connectors will take you to discuss, which lithium-ion battery or lead-acid battery is more suitable for 48V energy storage system for house?

48V energy storage system for house
The use of lead-acid batteries
Since the 1970s, lead-acid batteries have been used in energy storage system for houses as energy storage batteries. It is similar to a traditional car battery, but charges and discharges more frequently than a car. Since the cost of lead-acid batteries is lower than that of lithium-ion batteries, this makes home users more inclined to choose lead-acid batteries.
Lead-acid batteries and lithium ion batteries in stationary energy storage systems
The cycle times of lead-acid batteries are up to about 500 times, while the cycle times of lithium-ion batteries are mostly between 2000-6000. Therefore, in the high frequency charge and discharge cycles of the 48V energy storage system for house, the user will have to replace the lead-acid battery frequently.
Lead-acid batteries also have the problem of low discharge, charge and discharge efficiency, consume extra energy during use, and cannot charge and discharge as quickly as lithium battery systems. Therefore, under the same conditions, lead-acid batteries will require more capacity and space, that is, greater volume and weight.
The use of lithium ion batteries
In recent years, lithium-ion batteries have developed rapidly and become the first choice for many devices. Power banks, mobile phones, notebooks, cars, etc. More and more 48V energy storage system for house uses LiFePO4 powerwall battery. But lithium-ion batteries also have some limitations, first of all, the cost is in the first place.
The upfront cost of lithium-ion batteries is higher than that of lead-acid batteries. With the improvement and optimization of the lithium battery industry chain, the cost of lithium-ion batteries is decreasing. Relevant research data showed in a November 2017 report that the installation cost of a lead-acid battery energy storage system for home solar energy was between $598 and $635 per kilowatt-hour. Lithium-ion batteries cost $831 to $1,089 per kilowatt-hour to install. But the low cost of lead-acid batteries hides some additional costs, such as shorter operating life and higher operating costs.
Li-ion battery with 48V energy storage system for house
The cost of lithium ion and lead acid batteries currently used for 48V energy storage system for house is significant. They can be used as stand-alone energy storage systems or in conjunction with residential solar power generation facilities to meet some or all of the energy needs of home users or businesses.

In terms of operating life, lithium-ion batteries are expected to last 8-10 years, and they are able to charge and discharge to higher levels without significantly reducing capacity. The lithium-ion battery used for 48V energy storage systeml for house is not light, but compared with the lead-acid battery of the same specification, the volume and weight are reduced by about 30%; it can be charged faster at higher voltage; the safety performance is also greatly improved improvement.
Of course, there are many advantages of lithium-ion batteries. All in all, lithium-ion batteries have more advantages than lead-acid batteries in 48V energy storage system for house applications, and as the cost decreases, they will be more and more widely used in energy storage systems.
