As energy prices continue to fluctuate and more homeowners across the South East look for greater control over their electricity, battery storage is quickly becoming a must have alongside solar. At SolarTherm UK, we’re always focused on delivering reliable, future proof technology – which is why we’re proud to introduce the latest addition to our range: Hanchu ESS battery systems.
Designed with performance, safety and intelligent energy management in mind, Hanchu ESS represents a new standard in residential and commercial battery storage.
Why Battery Storage Matters More Than Ever
With rising electricity costs and the growing popularity of EVs and heat pumps, households in Essex, Kent and the wider South East are using more energy than ever before.
Battery storage allows you to store surplus solar energy instead of exporting it, meaning you can use your own self-generated electricity around the clock, reducing reliance on expensive grid electricity. Battery storage also allows you to take advantage of smart tariffs like Octopus Flux, giving you windows of preferential export prices and lower overnight import costs.
Depending on the make and model of your battery, you may also have backup power during grid outages – from one or two sockets or circuits to full home backup.
Hanchu ESS takes these benefits and enhances them with cutting edge technology.
What Makes Hanchu ESS Different?
True Energy Independence
Hanchu ESS features a full uninterrupted power supply (UPS) system, meaning your home can automatically switch to battery power during a power cut – keeping essentials (and more) running without interruption.
Advanced Safety You Can Trust
Safety is non-negotiable when it comes to battery storage. Hanchu ESS includes:
- ICE 62619-certified battery technology
- Premium Lithium Iron Phosphate (LiFePO4) cells – known for stability and long lifespan
- Built in aerosol fire suppression system
- Intelligent thermal management with heating and cooling
This makes it one of the safest battery systems available on the UK market today.
High Performance and Maximum Efficiency
Hanchu ESS systems are engineered to get the most out of every unit of energy:
- 95% Depth of Discharge (DoD) – more usable energy than many alternatives
- 100A discharge rate – supports high demand homes
- All in one hybrid inverter and battery system – streamlined efficiency and installation
- Expandable up to 16 batteries per controller
Whether you’re a typical household or running a high consumption property, the system scales with you.
Smart Energy, Made Simple
One of the standout features of Hanchu ESS is its intelligent control system:
- Hi-Agent AI Assistant 360 – optimises when to store, use or export energy
- Remote monitoring and control via app
- 24/7 live system tracking
This means your system is constantly working to reduce your bills – without you needing to think about it.
Built for British Conditions
With an IP65 rating, Hanchu ESS batteries are suitable for both indoor and outdoor installation – ideal for UK homes where space can vary. Integrated heating technology also ensures consistent performance even in colder temperatures.
Flexible for Every Property
Hanchu ESS offers a wide range of configurations:
- 2.56kWh
- 5.12kWh
- 9.4kWh
Available in both single phase and 3-phase systems, making them suitable for residential homes, larger properties and commercial premises.
Designed for the Smart Energy Future
Hanchu ESS integrates seamlessly with solar PV systems, EV chargers and smart tariffs such as Octopus Flux. This allows homeowners to charge their batteries when electricity is cheapest and use it when prices are highest – maximising savings.
