⚙How It Works
A high-voltage cluster strings many cells in series to reach hundreds of volts, so the same energy flows at much lower current. Lower current reduces cable and connector losses and heat, raising round-trip efficiency — the difference between a 48 V bank and a 400 V cluster on a large daily cycle is measurable. High-voltage clusters are the building blocks of commercial cabinets and containerised storage.
▦Structure & Composition
The ESS-HV cluster assembles multiple series-connected modules into a rack or cabinet, terminated in a high-voltage box that houses the main contactor, current sensor and insulation monitor. A cluster-level BMS coordinates the module BMS boards and reports SOC, SOH and protection status to the PCS over CAN or Modbus, scaling cleanly from tens to hundreds of kilowatt-hours.

Applications
Selection Guide
- Commercial and containerised storage where the battery scales from tens to hundreds of kWh.
- Choose high voltage for lower current, thinner cables and better round-trip efficiency on large banks.
- Confirm the PCS DC voltage window matches the cluster's operating range before finalising the design.
Frequently Asked Questions
When is high voltage better than 48 V?
Above roughly 15–20 kWh, high voltage lowers current and losses enough to justify the more complex architecture.
How does the cluster BMS work?
Module BMS boards report to a cluster controller, which manages SOC/SOH, balancing and protection and talks to the PCS.
Can clusters be paralleled?
Yes, for container-scale systems multiple clusters feed the same DC bus under a system-level BMS.
