PV inverters integration
SunSpec: brands beyond the list too
SunSpec is an open standard supported by many inverter manufacturers. If your inverter speaks SunSpec, Voltmasters EMS connects to it, even if the brand is not listed separately.
SunSpec
Supported devices
- Generieke SunSpec-omvormer
Any inverter that supports the SunSpec standard. Not sure whether your inverter speaks SunSpec? Send us the model and we will check.
What the EMS gets out of your SunSpec 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 the SunSpec integration is useful
Not every brand has its own detail page, but many inverters speak the SunSpec standard over Modbus. Through that generic connection the EMS reads and limits production: curtailment during negative prices, injection limiting and monitoring, even for less common brands.
How it works

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 SunSpec integration
What is the SunSpec integration?
SunSpec is an open Modbus standard that many inverter manufacturers support. Through this generic connection the EMS also controls inverters that are not listed separately.
How do I know if my inverter speaks SunSpec?
Many commercial inverters support SunSpec over Modbus. Send us the brand and model and we will confirm whether the generic connection works.
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 SunSpec 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.
