Future expansion uses the same battery family. The page shows up to eight batteries: 3.68kW, 5kW and 6kW controller families can be expanded further through a tailored HEG design, while 7kW, 8kW and 10kW systems use a battery combiner box and are limited to eight batteries.
Works with Octopus
Hanchu home battery systems can be set up around compatible Octopus time-of-use tariffs. Hanchu ESS is listed in Octopus’ Intelligent Octopus Flux eligibility selector; Octopus confirms final availability and enrolment.

Why Hanchu is worth looking at properly
The features homeowners ask about, without hiding the detail.
The exact system needs to suit the controller, battery family, supply and property. These are the practical Hanchu features HEG explains before a final survey-led recommendation.
01
Build from one battery family
Choose a 3.68kWh, 5.12kWh or 9.4kWh Hanchu battery family. Future expansion uses that same family, giving the system a clear starting point.
02
Space to scale
3.68kW, 5kW and 6kW controllers can support up to 16 same-family batteries; 7kW, 8kW and 10kW controllers support up to eight with a compatible combiner arrangement. Public package prices show up to eight batteries.
03
Power that fits the controller
3.68kW, 5kW and 6kW controller routes can charge a compatible battery system at up to 5kW; their stated discharge capability is 3.68kW, 5kW and 5kW respectively. 7kW, 8kW and 10kW routes are matched to their stated ratings.
04
12-year Hanchu warranty
Every Hanchu battery package shown by HEG includes a 12-year manufacturer warranty and a 5-year insurance-backed guarantee.
05
Shadow Scan and Octopus-ready features
Applicable Hanchu 7–10kW hybrid models include Shadow Scan and compatible Auto Octopus tariff functionality. HEG confirms the selected controller and configuration at survey.
06
See what the system is doing
Compatible Hanchu systems use iESS and app-based monitoring so you can view performance, settings and historical information after commissioning.
Why Hanchu ESS
More than a battery: a system designed around how you use energy.
A Hanchu system can be designed to store solar for later, charge in selected lower-cost windows and make everyday energy use easier to understand. HEG matches the controller, battery family and practical installation route to your home at survey.
01
A clear energy picture
Use the Hanchu iESS app and web portal to view compatible system activity, generation, storage and household energy information.
02
A system with room to plan
Choose the right starting battery family and capacity, then discuss future expansion within the compatible system design.
03
Backup when it matters
A compatible Hanchu Gateway can be designed as a separate whole-home backup option, with circuits and arrangement confirmed at survey.
Hanchu iESS monitoring
See your compatible energy system in one clearer place.
Hanchu iESS is the app and web-platform story behind the hardware. It is designed to give compatible Hanchu equipment an accessible view of system information, alerts and energy activity after commissioning. HEG will confirm the features available to the chosen configuration.

“Home Energy Group Ltd is the best. They went above and beyond to help me. A previous company botched fitted a VP panels and Battery Inverter system — Home Energy Group Ltd are the only company who willingly rectified all the previous installation ensuring everything was correct and safe. I will always recommend them.”

“Called quite a few companies re installing a battery storage system. Most were quite pushy. When I called HEG, I was given good, easy to understand helpful information. They answer the phone promptly and are always helpful. The two electricians that installed the system have done a good job and left the house clean.”
