The Victron HS19 high voltage inverter/charger only works with supported and compatible high voltage batteries.

Victron provides the following support documentation to assist qualified system designers and installers to select suitable batteries for their application.

This information should always be verified with the battery manufacturer.

These batteries are strongly recommended to be connected via “BMS-Can” (CANBus) to a [GX device](https://www.victronenergy.com/live/venus-os:start “venus-os:start”). The HS19 supports direct battery connection without a GX device, see product manual further details.

• FDCan support is required for paralleling inverters.
• Voltage ranges are the operating window of a full stack as published by the manufacturer. The Hubble range shown uses the published 3-module discharge cutoff and 8-module equalised charge values.
• LBSA rack voltage range is computed from per-module values (66 V cutoff, 84.3 V charge); LBSA does not publish a stack-level range.
• ZYC SIMPO Pro E upper operating voltage of 1306 V is straight from the ZYC spec table; verify against inverter DC input limits.
• Note on data status: Voltage range and module count figures were compiled from manufacturer datasheets and product pages (June 2026) and are not verified. Sources are listed on each brand subpage.

Batteries can be dangerous, and high voltage batteries more dangerous still.

In addition to the chemical risks of lithium, HV batteries operate at voltages that are lethal on contact. There is no safe way to touch a live HV battery circuit. DC arcs at these voltages do not self-extinguish, and a fault can sustain an arc long enough to cause fire and severe injury. Installation, commissioning and service must only be done by people trained and qualified to work on high voltage DC systems, following local regulations, with appropriate PPE and proper isolation and lock-out procedures.

Some types of lithium cells are safer in the way that they won't catch fire when treated wrongly. Note though that while mostly not burning, there will be mess and smell. Other lithium technologies are less/not intrinsically safe and will catch fire by overcharging them for example. To go into more detail about all this is beyond the scope of this page, but please take this seriously and also be aware that Victron does not take any responsibility for this.

Worded simply: a battery must be intrinsically safe, and include its own large disconnect mechanism such as a contactor, rated to break the full DC voltage and current of the stack.

Only relying on digital signals telling our inverter/charger to stop charging is not sufficient. At these voltages this requirement matters even more: the battery must be able to physically disconnect itself in a fault situation.
