Designed for hybrid power plants, the DEIF ASC 150 Solar enables effective photovoltaic inverter control and maximises sustainable power penetration in greenfield and brownfield applications. The flexible controller complies with the SunSpec standard and is compatible with a wide range of inverter brands. It is also capable of interfacing with many different controllers and meters, letting you configure it to your exact requirements.

Built-in scalability and flexibility

You have many options when configuring the ASC 150 Solar. It can run in a range of different plant modes, including fixed power and Mains Power Export (MPE). It has four built-in AC (voltage and current) measurements that you can use to calculate the power set points for your PV power plant.

You can even reconfigure your ASC 150 Solar for other applications by setting its parameters or using an external energy management system (EMS), turning the controller into any other ASC 150 or AGC 150 variant, for example a genset controller. These and other features let you use the controller exactly the way you want, and scale and redesign your plant as needed.

Ideal for a wide range of applications

The flexibility and features of the ASC 150 Solar, and its ability to operate in temperatures ranging from -40 to +70 °C, make it ideal for a wide range of grid-tied and off-grid applications. You can use it to add solar power to an existing site, or with other DEIF controllers in a power/energy management system. The controller can handle a PV system with up to 32 inverters, and it responds quickly to load and weather changes.

Fast Ethernet Modbus master communication

The ASC 150 Solar is designed for rapid communication with your solar plant: Using Modbus master communication via Ethernet, the controller can communicate with your PV inverters much faster than over an RS485 connection. This helps your plant respond quickly to changes in operating conditions, and you get faster read-out of status and monitoring information.

Includes utility software and emulation tool

Using the free PC-based DEIF utility software, you can easily set up your ASC 150 Solar and quickly configure inputs, outputs, and parameters. With the built-in emulation tool, you can test and verify the functionality of your application before commissioning. This saves time and helps you prevent costly equipment malfunctions.

Great overview with user-friendly display

The user-friendly, IP65 protected display shows your current configuration using a clear and simple line diagram, letting you check the status of all power sources at a glance (with arrows indicating the power flow). The display supports multiple languages, including Chinese, Russian, and other languages with special characters.

Enables remote monitoring

The ASC 150 Solar is compatible with the responsive DEIF Insight remote monitoring service which gives you an instant remote overview of your connected assets with real-time genset data, a customisable dashboard, GPS tracking, equipment and user management, email and/or SMS alerts, and cloud data management.
