About Residential Lithium storage batteries

Lithium batteries have become the mainstream choice in household /residential energy storage projects, the reason is development of lithium-ion battery technology and the rapid decline of cost, and the market share of newly added chemical batteries has reached more than 95%. Lithium iron phosphate battery became a priority choice for residential battery storage systems.

cycle life compared with other type lithium batteries, in additional, it has no memory effect. This is critical for solar power energy storage system. Because solar pv generator is not stable when it charging the batteries. In this way, residential battery storage owner no longer being limited to using only half of the stored power in a battery effectively doubles their capacity. Battery system can be charged anytime, no matter how much current the invertor and PV generated

Different from lead acid battery. The LiFePo4 battery storage system required a BMS. And it is smartly controlling the battery cells inside for charging and discharging. All is managed and monitor by the BMS. The BMS will communicate with invertor directly to make sure the completely system works consistent in a best condition. Leadstone Energy residential battery storage systems come with communication functions. This will tell the solar controller or invertor when to charge, when stop to discharge. All battery state and information are monitor in real-time. This is very important when using battery systems with solar arrays PV system, because the inverters in a solar array system require power to begin making power, regardless of whether they are tied to the grid or not.

Why need home electricity battery storage?

Storage system will achieve kinds of functions according to power grid dispatch command, which includes items as follows:

Best battery for home energy storage

How much storage does my home need

Just like solar-only systems, the size of your rechargeable solar battery system is determined by your unique energy needs and habits. Factors such as the amount of electricity you use at home and the devices and appliances you want to back up will play a key role as you select the right battery storage solution for you. Normally, if the solar power just for illumination, You will need a less then 5Kwh home battery energy system. If there is a air-condition, or other electric powered stove. You probebely need at least 5Kwh or 10kwh more.

Leadstone Energy ESS Advantages

Leadstone Energy Residential Energy Storage Systems (ESS)

Leadstone Energy Residential Storage Solutions (ESS) offer a wide variety of products to create and manage resilient energy infrastructures at an optimal cost. ESS offers two primary use cases. The first is creating utility-independent, solar-powered homes (residential ESS). On a larger scale, the second use case is utility supplementing generated power during periods of high demand (utility-scale ESS).

Older generation residential solar energy systems are tied to the utility power grid via inverters, which convert power from solar panels to AC electrical power during daylight hours. Marketable excess power might be sold back to utility companies. However, during the hours of darkness, the end-user is relying on the utility’s electricity supply. Utility companies are aware of these limitations and adjust their pricing models accordingly. Residential customers pay based on “time-of-use” rates, which are higher when solar power is not available.

Behind-the-meter ESS is utilized at this point. The electricity that is collected via solar panels charges batteries, the energy is then stored. When using these batteries with an inverter, the demand for AC power can be fulfilled at any time.

48100 comes with two different product models, 48100P and 48100S, to support both P is a battery unit allowed you parallel more unit to increase the system capacity. While P will possible to connect in Series to increase the battery system DC voltage.

Beside the battery system. Leadstone Energy also offer related solar charging controller based on different voltage and current. Custom can easy just connect all component together and start to use the whole system.

Here is link for our Solar charging controller. If you still have some questions, please feel free to contact our sales Consultants. You can email or call us directly based on contact page information.

BATTERY MANAGEMENT IN ESS

In ESS, a battery management system fulfills two main functions, namely battery protection and battery monitoring.

Battery Protection

Detecting a variety of fault conditions and protecting the battery from damage during the charging and discharging process is the main purpose and functionality of a BMS. Operating a battery outside of its specifications causes damage to the battery cells and leads to battery failure, producing maintenance efforts, and significant cost impact. Batteries must be closely monitored during charging and discharging to avoid these negative effects.

Protection must be provided against:

Those designing with Leadstone Energy solutions will benefit from :

Battery Monitoring

A battery must be monitored systematically, to protect it. The battery management system is in charge of monitoring each of the cells in a battery pack and ensures that they are operated within the safe operating range. Various parameters, such as cell voltage, SOC, state of health (SOH), and the temperature, have a decisive impact on the performance, safety, and lifetime of batteries. A battery needs to be protected against possible external faults that would put the system in danger. Protecting the battery from damage during the normal function of the system (charging and discharging process) is one of the main functionalities of a BMS. Within Infineon’s product portfolio, designers will find the right devices to disconnect the battery system in case a fault is detected, thereby protecting its value. They will also help to detect system faults like overcurrents and short circuits

Advanced Battery managment System

The battery is the core energy storage device of the system and needs to be monitored online status in real time, so the importance of BMS is self-evident. In the BMS management system, BCU real-time communicates with

The BCU calculates and analyzes all the information of the battery pack and then intelligently manages the system, communicating with the independent CAN bus and achieving the secondary protection of charge and discharge through a relay. The latter ensures an effective isolation for strong electricity and weak electricity, meets customer’s demand for diverse security control and guarantees a stable and efficient operation of the system.

BMS / BMU are the Core Technology

Li-ion cells should always be used with a protection circuit to prevent the cell from over charging or over dis-charging. Choosing the correct circuit and applying it appropriately is vital to the longevity your batteries and your own safety. Leadstone Energy test each Cells and BMS/PCB/PCM before manufacturing and promise it is functional and safe.

BMS / PCB / PCM is the “heart” of Lithium battery pack. BMS (Battery Management System) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.
