Battery storage (BESS) integration
Oztek OZpcs under smart control
Oztek builds power conversion systems for commercial and industrial battery storage. Voltmasters EMS turns the storage behind it into an earning asset: market-driven charging and discharging, peak shaving and self-consumption optimisation.
Supported devices
- OZpcs
- Generiek
The OZpcs power conversion system and the generic Oztek inverter. Set the device to remote control, because in local mode it ignores the setpoints from the EMS.
What the EMS gets out of your Oztek installation
- Trade on the imbalance market and dynamic prices, quarter hour by quarter hour
- Peak shaving: keep peak power and capacity tariff under control
- Maximise self-consumption together with PV and EV chargers
- Fluvius telecontrol and grid compliance, certification included
- Real-time monitoring with automatic incident detection
Why installers combine Oztek and Voltmasters
Oztek delivers the power conversion system, Voltmasters adds the intelligence. The OZpcs speaks standard SunSpec Modbus TCP, so no brand-specific adapter is needed on the controller. The EMS aligns the battery with the market, the PV and the consumption and guards the grid connection. The Voltmaster Controller runs the optimisation locally, even without internet.

FAQ
Questions about the Oztek integration
Which Oztek devices does Voltmasters support?
The OZpcs power conversion system and the generic Oztek inverter, both over SunSpec Modbus TCP.
What can the EMS do with an Oztek inverter?
Market-driven charging and discharging, peak shaving, self-consumption and grid compliance, controlled from a single platform.
Does the system keep working when the internet drops?
Yes. The Voltmaster Controller runs the optimisation locally in the cabinet. If the connection drops, control, peak shaving and the safety limits simply stay active.
How do I connect a Oztek OZpcs to the EMS?
The Voltmaster Controller connects to the device over the local network. The step-by-step instructions are in our documentation, and as a certified partner we guide your first commissioning from start to finish.
