PV inverters integration
The broad Sungrow range under control
Sungrow has one of the broadest inverter ranges on the market, from the RT series for rooftops to large-scale CX inverters. Voltmasters EMS monitors and curtails production: curtailment during negative prices, injection limiting and real-time monitoring.
Supported devices
- RT-reeks
- KTL-M-reeks
- CX-reeks
- KU/KTL-reeks
- HV/BF-reeks
- HX/TX-reeks
Dozens of models across the RT, KTL-M, CX, KU/KTL, HV/BF and HX/TX series. Send us the model of your inverter and we will confirm support.
What the EMS gets out of your Sungrow installation
- Automatic curtailment during negative prices
- Injection limiting, up to zero injection on the grid connection
- Align production with battery, EV chargers and site consumption
- Yield monitoring with alerts on deviations
- Ready for the connection requirements of the grid operator
Why installers combine Sungrow and Voltmasters
With nearly sixty supported models, Sungrow covers almost every project type. The EMS aligns production with batteries, EV chargers and consumption and turns every inverter into a controllable asset. If you mix brands, the EMS controls everything as one system.

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.
FAQ
Questions about the Sungrow integration
Which Sungrow inverters does Voltmasters support?
A broad range across the RT, KTL-M, CX, KU/KTL, HV/BF and HX/TX series, nearly sixty models in total. Send us the model and we will confirm.
Can the EMS curtail Sungrow production during negative prices?
Yes. The EMS automatically reads the day-ahead prices and limits the inverter when injecting costs money, up to zero injection.
Does this work together with hardware from another brand?
Yes, the EMS is brand-independent. A battery, PV inverter, EV chargers and meters from different manufacturers are controlled together as one optimised system.
How do I connect a Sungrow inverter 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.
