Because lithium batteries have below benefit:
Cost Effectiveness: LiFePO4 battery stores much more energy over its life time with less replacement needed compared with lead-acid batteries. This makes LiFePO4 battery the cheapest maintenance-free battery.
Smart Management: With the integration of Bluetooth, you can obtain readings of voltage, current, temperature, and the state of charge directly from your smart phone.
Longer Service Life：LiFePO4 batteries have the longest service life among all battery products. This new technology will provide you with 4,000 complete charge and discharge cycles at 80% DOD; whereas, normal lead-acid batteries only provide 350 cycles.LiFePO4 battery's floating service life can reach to 15 years. The longer service life reduces battery replacement frequency and therefore lowers the Total Cost of Ownership (TCO).
Guaranteed Safety：LiFePO4 batteries guarantee the highest safety and eliminate the risk of fire and explosion. The built-in BMS prevents over charge, deep discharge, and over-heating. This protection lets the battery take care of itself, making it safe and robust. State of charge (SOC) and state of health (SOH) can also be obtained to help manage the batteries throughout the entire life cycle.
Fast Charge：LiFePO4 batteries can charge and discharge at a high rate providing maximum versatility for all types of applications. Fast charging minimizes downtime, while full charging is possible within one hour.
Drop-in Replacement：LiFePO4 battery comes in industry-standard sizes, and they are designed to replace lead-acid batteries in any deep cycle application. They can replace lead-acid batteries directly, and you don't need to replace the original lead-acid battery charging systems, or change the charging settings.

An off-grid solar photovoltaic (PV) energy storage system is a self-sufficient system that generates and stores electricity from solar panels without being connected to the main electricity grid. It typically consists of solar panels, a charge controller, batteries to store the energy, and an inverter to convert the stored energy into usable AC power. This type of system is often used in remote areas or locations where access to the grid is limited or unreliable.
On the other hand, a grid-connected solar PV energy storage system is connected to the main electricity grid. It generates electricity from solar panels, which can be used to power the premises or sent back to the grid for credits or compensation. These systems also include energy storage to store excess electricity for later use when solar generation is low. The main difference is that grid-connected systems rely on the main electricity grid for backup or additional power, while off-grid systems are designed to operate independently without grid support.

There are several reasons why lithium-ion home photovoltaic (PV) energy storage systems have become popular:
1. High energy density: Lithium-ion batteries can store a significant amount of energy in a small and lightweight package. This makes them suitable for residential applications where space is limited.
2. Efficiency: Lithium-ion batteries have high charge and discharge efficiencies, allowing effective energy storage and retrieval.
3. Long life: Lithium-ion batteries have a longer lifespan than other battery technologies, such as lead-acid batteries.
4. Scalability: Lithium-ion energy storage systems can be easily scaled up or down to meet the specific energy storage needs of households. This flexibility allows homeowners to tailor their energy storage capacity to their energy consumption patterns.
5. Fast charging and discharging: Lithium-ion batteries can be charged and discharged at high rates, allowing rapid energy transfer between the PV system and the battery storage.
6. Maintenance free: Lithium-ion batteries are generally maintenance free and require minimal upkeep compared to other battery technologies.
7. Compatibility with PV systems: Lithium-ion batteries are compatible with solar PV systems, which are widely used for residential solar power generation.

To configure a suitable off-grid lithium-ion home solar photovoltaic energy storage system, follow these steps
1) The system size should be determined based on the user's energy requirements, taking into account factors such as daily energy consumption, peak power requirements and seasonal variations.
2)The appropriate type and capacity of batteries must be selected to store excess solar energy for use during periods of low or no sunlight. A charge controller is also required to regulate the charging and discharging of the batteries to ensure their longevity and optimum performance. The choice of inverter is essential to convert the DC power generated by the solar panels into AC power for household appliances.
3)Proper wiring, grounding and safety measures should be implemented to ensure the efficient and safe operation of the off-grid photovoltaic energy storage system.
4) Monitor and control the system: Install a monitoring system to track your solar panel performance, battery charge level and energy consumption. This will help optimise the efficiency of your system and identify any problems.
5) Maintain and service: Inspect and maintain your system regularly to ensure optimum performance. Follow the manufacturer's guidelines for battery maintenance, solar panel cleaning and replacement of faulty components.
6) Consider backup options: If you anticipate extended periods of low solar generation, consider backup options such as a standby generator or connection to the grid as a secondary power source.
It is recommended that you consult a professional solar installer or engineer to ensure that the system is designed and installed correctly and meets safety and regulatory requirements.

Home energy storage systems play an important role in several aspects, including providing backup power, balancing electricity supply and demand, improving energy efficiency, reducing energy costs and reducing dependence on traditional energy sources. These features make home energy storage systems a key player and a major contributor to the protection of the environment and the early achievement of mankind's goal of carbon neutrality.

There are several reasons why you might choose a lead acid battery over a lithium battery:
1. Cost: Lead-acid batteries are generally cheaper to manufacture and purchase than lithium batteries. This makes them a more cost effective option, especially for applications that require large battery banks.
2. Safety: Lead acid batteries are considered to be more stable and safer than lithium batteries. They have a lower risk of thermal runaway or explosion, making them suitable for applications where safety is a concern.
3. Durability: Lead-acid batteries have a longer life than lithium batteries, especially in deep-cycle applications. They can withstand frequent deep discharges and recharges without significant loss of capacity.
4. Performance under extreme conditions: Lead-acid batteries perform better in extreme temperatures, both high and low, compared to lithium batteries. They can operate over a wider temperature range without significant loss of performance.
5. Recyclability: Lead acid batteries are highly recyclable, with a recycling rate of over 99%. The lead and plastic components can be recycled and reused, reducing environmental impact. Lithium batteries, on the other hand, have a lower recycling rate and present challenges in terms of proper disposal and recycling.
The choice between lead-acid and lithium batteries depends on the specific requirements of the application and the trade-offs you are prepared to make.
