Home Energy Storage: Keeping Energy in Your Hands

Under the wave of energy transition and sustainable development, home energy storage systems are gradually entering thousands of households, becoming the new choice for modern home energy management.   As a manufacturer with 14 years of experience in producing lithium iron phosphate batteries for energy storage, GSL Energy is committed to providing users with safe, reliable and efficient energy storage solutions to help home users reduce electricity costs and increase energy independence.

How does a home energy storage system work?

Simply put, a home energy storage system is like a large ‘rechargeable battery’ that stores electricity and releases it when needed.   Its core components include:

1.   Battery Pack - The Heart of Energy Storage

GSL Energy uses high-performance lithium iron phosphate (LiFePO4) batteries, which have the following advantages over traditional lead-acid batteries:

Long cycle life: Support 6500+ cycles, with a service life of more than 10 years.

High safety: passed UL9540, IEC62619, CE, UN38.3, and other international certifications, fire and explosion-proof.

High-efficiency energy conversion: energy conversion efficiency is up to 98%, reducing energy loss.

2.   Inverter - the ‘brain’ of energy storage

The inverter is responsible for converting between direct current (DC) and alternating current (AC): the DC power stored in the battery is converted into the AC power required by household appliances.   Compatible with solar energy systems to store electricity generated from photovoltaic power generation and increase the utilization of renewable energy.

3.   Energy Management System (EMS) - Intelligent Control Centre

GSL Energy's intelligent EMS system can:

Automatically optimise charging and discharging strategies, and rationally arrange power usage according to fluctuations in grid tariffs, weather conditions and power demand.

Monitor the system status in real time, remote control via WiFi/APP to check the power consumption and system operation at any time.

Off-grid or off-grid mode switching, adapting to different energy environments and ensuring stable power supply.

Workflow of home energy storage system

Charging: The system is charged when the electricity price is low or when there is enough solar energy, and it can be self-generated and self-consumed by using PV+energy storage.

Storage: Batteries store electricity to ensure that it is available at all times.

Discharge: The system automatically discharges to supply power to the home during peak tariff hours or power outages.

Intelligent management: EMS monitors and optimises energy flow in real time to ensure efficient operation.

Core values of home energy storage systems

Save on electricity costs:

Adopting peak and valley tariffs, charging at low tariffs and discharging at high tariffs reduces electricity costs.

Example: In the U.S., a GSL 10kWh energy storage system can save 30-50% on annual electricity bills.

Power outage emergency protection:

Automatically switches to off-grid mode during power outages to ensure uninterrupted home power.

Example: In November 2024, GSL Energy installed a 20kWh home energy storage system in Kenya, effectively guaranteeing the demand for electricity during power cuts.

Promote clean energy utilisation:

Combining solar energy to maximise the use of renewable energy and reduce carbon footprint.   Case in point: GSL Energy's multiple home energy storage projects in Puerto Rico, reducing CO2 emissions by 5 tonnes per year.

Grid-connected benefits:

In some countries, customers can sell excess electricity back to the grid for additional revenue.

Key factors in choosing a home energy storage system

Battery type: choose lithium iron phosphate batteries for safety, reliability and longer life.

System capacity: choose the right battery capacity according to the household electricity demand, such as 10kWh for small households and 20kWh for large households.   There are also 1-5MWH large industrial and commercial energy storage batteries,

Future trend: let the energy storage become the family standard

In the future, home energy storage will become an important part of the smart home, GSL Energy will continue to promote technological innovation, provide smarter, more efficient and more environmentally friendly energy storage solutions to help the global energy transition.
