How a Home Energy Storage System Works

Solar Panels / Wind Turbine

Renewable sources generate electricity from the sun and wind.
Battery Storage (Lithium or Sodium)

Clean energy is stored in solar battery storage units such as lithium-ion or sodium-ion batteries, allowing you to use it anytime — day or night.
Charge Controller

The controller regulates the flow of electricity to protect the batteries from overcharging or deep discharging.
Inverter

Converts the stored DC electricity into AC power used by household appliances.
Smart Meter

Measures electricity flow between your system, your home, and the grid.
Home Usage

Power is delivered directly to your appliances, lighting, and electronics.
Grid Connection

If your system generates excess power, it can be exported to the grid. If more energy is needed, the home draws power from the grid — keeping you connected and secure.
Together, these components form a flexible and intelligent battery energy storage system. Whether you choose solar panel battery storage, home power storage batteries, or a hybrid with wind energy, this system reduces energy bills, improves self-reliance, and ensures backup power during outages.

Lithium vs. Sodium Battery Storage: Which One Fits Your Needs?

Feature	Lithium-Ion Battery Storage	Sodium-Ion Battery Storage
Energy density	High — compact size, more energy per kg or liter	Moderate — larger size needed for same capacity
Charging speed	Fast charging and discharging	Moderate charging speed
Thermal stability	Requires temperature regulation (sensitive to heat)	Excellent thermal stability — handles high temperatures with ease
Safety	Needs built-in BMS for fire and overheat protection	Naturally safe — non-flammable and less reactive
Environmental impact	Recyclable, but mining impacts and disposal need attention	Lower environmental footprint and easier to recycle
Weight	Lightweight and compact — ideal for space-constrained environments	Heavier and bulkier — requires more space
Best applications	Home battery storage, EVs, urban solar setups, mobile/off-grid systems	Battery storage for solar panels in rural areas, microgrids, backup power

Frequently Asked Questions About Energy Storages

It depends on your energy needs, budget, and site conditions. Our team offers free consultations to recommend the best-fit solution.
Yes! Our batteries integrate seamlessly with wind turbines, solar panels, and hybrid setups.
With proper use, lithium batteries last 10–15 years, and sodium batteries offer robust performance and safety even in extreme conditions.
Absolutely. Sodium-ion technology is non-flammable and an excellent alternative for home energy storage.
BESS stands for Battery Energy Storage System — a technology that stores electricity for later use. A BESS battery energy storage system is essential for balancing supply and demand in renewable energy setups. It allows excess energy from solar panels or wind turbines to be stored in solar storage batteries, making power available during outages, at night, or when grid demand spikes.
While lithium ion battery storage and sodium-ion technologies are the most popular today, other emerging options include sodium-sulfur batteries, flow batteries, and solid-state batteries. Some homeowners also use lead-acid storage batteries for solar panels, though they offer shorter lifespans and lower efficiency compared to modern home battery storage systems. Freen continually evaluates the most reliable and safe battery storage solutions on the market.
