How three-phase storage works
A high-voltage battery design for a three-phase supply.
The correct design depends on the electricity supply, current loads, solar arrangement, site access and storage objectives. Hanchu three-phase controllers are available from 6kW to 20kW, with matching stated charge and discharge capability.
Select HV storage
Compare the 2.7kWh and 5.12kWh high-voltage battery families in live package stacks from three to ten batteries.
Confirm at survey
HEG checks supply, panel array where relevant, electrical design, position and practical installation scope before work begins.
Three-phase package prices
Choose a three-phase controller and high-voltage battery size.
These are current HEG indicative fully installed packages for Hanchu three-phase storage. Select the controller and high-voltage battery family, then explore a stack from three to ten batteries. HEG confirms supply, solar configuration, positioning and final scope at survey.

Three-phase installation examples
An original installation scene for each high-voltage battery family.
These are original illustrative Hanchu three-phase installation scenes created from the supplied product references. Each scene shows one full controller beside the relevant complete high-voltage stack; the final electrical room, equipment spacing and cable route are always designed around the site.
5.12kWh high-voltage installation concept
One full three-phase controller alongside one complete 5.12kWh high-voltage battery stack in an illustrative commercial electrical room.
2.7kWh high-voltage installation concept
One full three-phase controller alongside one complete 2.7kWh high-voltage battery stack—with no miniature secondary battery stack.
More than a package
Three-phase storage can support several design routes.
The same Hanchu high-voltage platform can be assessed for retrofit storage, an inverter upgrade, solar integration, monitoring and a carefully designed resilience conversation.
AC retrofit route
Keep a suitable existing solar inverter while adding surveyed three-phase storage.
Hybrid solar route
Assess a new Hanchu hybrid controller where solar and storage are designed together.
High-voltage scalability
Start with a practical battery stack and plan a survey-led route for future energy needs.
App & portal monitoring
Use Hanchu monitoring to understand system performance after commissioning.
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
6–20kW three-phase options
Choose from 6kW to 20kW Hanchu three-phase controller ratings, with the selected equipment confirmed around the supply and project design.
02
High-voltage battery stacks
The selector shows 2.7kWh and 5.12kWh battery-family starting points in three-to-ten-battery package stacks.
03
Matched charge and discharge
The three-phase controller route is designed with matched stated charge and discharge capabilities for the selected rating, subject to final design.
04
12-year Hanchu warranty
The package route includes a 12-year Hanchu manufacturer warranty, alongside HEG’s 5-year insurance-backed guarantee.
Hanchu high-voltage storage
A three-phase system that keeps controller power and storage capacity in view.
High-voltage storage gives a clear way to match a Hanchu three-phase controller with a practical battery stack. The selector shows current installed package choices; the final supply, solar, position and electrical design remain survey-led.

“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.”
