Hoymiles HiOne Parallel Connection Harness – For 2+ Stack Installs
The Hoymiles HiOne Parallel Connection Harness is the official battery cable used to join a second HiOne battery tower to the inverter. Use it when a single stack is not enough and you need two floor-standing HiOne-8B-G3 towers on one HiOne hybrid inverter.
Key Features & Benefits
- Official HiOne tower-parallel battery cable
- Connects a second battery stack to the inverter
- Moulded right-angle connector for a secure, tidy fit
- Strain-relief boot to protect the cable at the plug
- Locking fastener to keep the connector seated
- Required for 2-tower HiOne installs
- Compatible with HiOne single-phase and three-phase AU inverters
What It Does
A standard HiOne tower stacks battery modules on one base under the inverter. For extra capacity, a second tower can be installed beside it. This harness carries the battery power/communication link from the second stack into the inverter’s parallel-battery port.

Typical System Layout
- Tower 1: inverter + up to 4 × BAT-HiOne-8B-G3
- Tower 2: up to 4 × BAT-HiOne-8B-G3
- This harness: links Tower 2 to the inverter
- Result: up to 8 modules / 64 kWh on one inverter
System Note
This is the parallel battery harness only. It is not a base, top cover, inverter or battery module. Each tower still needs its own HiOne Accessory Kit (base + top cover + handles). Follow the HiOne installation manual for cable routing, connector orientation and clearance.
Compatible With
- BAT-HiOne-8B-G3 battery modules
- HiOne-(5–12)S-G3-AU single-phase inverters
- HiOne-(8–20)T-G3-AU three-phase inverters
