Battery storage (BESS) integration
Sinexcel under smart control, from PCS to all-in-one
Sinexcel is a power-electronics specialist, from the modular PWS1 converter to the Isuna all-in-one battery. Voltmasters EMS turns it into an earning asset: intelligent charging and discharging, peak shaving and self-consumption optimisation.
Supported devices
- PWS1-500KTL-EX (M1 t/m M8)
- Isuna 10000T
- Isuna 12000T
- Isuna 15000T
- Isuna 20000T
The full PWS1-500KTL-EX series (M1 through M8) and the Isuna range from 10000T to 20000T. A different Sinexcel configuration? Send us the type plate.
What the EMS gets out of your Sinexcel 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 Sinexcel and Voltmasters
The modular PWS1-EX scales to 500 kW per cabinet, the Isuna series brings storage in a compact all-in-one enclosure. Voltmasters adds the intelligence and aligns the battery with the market, the PV and the site consumption. The Voltmaster Controller runs the optimisation locally, so control stays active even without internet.
How it works
How your Sinexcel connects to the EMS
Voltmaster Controller in the cabinet
The industrial DIN-rail controller sits next to the installation and runs the optimisation locally, even without internet.
Connect over the local network
You connect the device following the step-by-step guide in our documentation. We assist with commissioning on your first project.
Configure and go live
The installation appears in the platform: dashboards, control and monitoring are active right away.

Questions about the Sinexcel integration
Which Sinexcel systems does Voltmasters support?
The PWS1-500KTL-EX series (M1 through M8) and the Isuna all-in-one batteries 10000T, 12000T, 15000T and 20000T.
What can the EMS do with a Sinexcel battery?
Intelligent charging and discharging, peak shaving, load balancing, demand response and optimisation of solar self-consumption. Everything is 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 Sinexcel system 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.
