ASC 4 Solar
Automatic sustainable controller
Ideally suited for hybrid power plants, the integrated ASC-4 solar hybrid controller can interface to PV solar inverters, battery inverters and, for instance, diesel genset power sources. Moreover, it is compatible with leading sky imager solutions, enabling the ASC-4 to predict the weather and PV production and take counter-active measures.

Designed specifically to serve as a reliable, fully integrated and optimising link between sustainable power plants and genset power plants, DEIF’s automatic sustainable controller, ASC-4 Solar, is a renowned, market-leading solution for the industry.
Maximising sustainable power penetration
The ASC-4 Solar will in any operation mode automatically maximise sustainable power penetration, depending on the total load demand to the hybrid without compromising constraints such as minimum genset load demand.
Minimum genset load in island operation
Minimum genset load constraint is available in the ASC-4 Solar. The constraint applies in island operation only. This constraint will cause the sustainable power penetration to decrease in case it is compromised. This is to secure a certain amount of load on the gensets, eliminating the risk of reverse power situations and impure combustion and exhaust problems.
The ASC-4 Solar offers spinning reserve support as a percentage of the produced power, as part of an existing superior system (for instance an existing PLC system) or by means of short-term cloud detection functionality, depending on your application and requirements.
Ideal for self-consumption applications
While in grid parallel mode, the ASC-4 Solar is capable of feeding surplus PV energy to the grid and generate profit in accordance with grid operator feed-in tariffs. Alternatively, the ASC-4 Solar can regulate the PV production to match the self-consumption, thereby preventing any feed-in of PV power to the grid if prohibited by grid operator regulations.
Power management applications
DEIF’s Power Management system fully integrates the sustainable power plant and the genset plant into a unity. The ASC-4 is connected to the CAN bus constituting the internal DEIF Power Management communication link. For that reason, this approach is only applicable for plants equipped with AGC-4 or AGC 200 controllers.
In stand-alone applications, the ASC-4 knows little about the surrounding environment in which it is placed. Based on power readings and breaker positions, the ASC-4 Solar determines the power references to the sustainable power plant. This approach is applicable for integrating sustainable power in already commissioned genset plants, whether they are equipped with DEIF controllers or not. Stand-alone applications support up to 16 gensets. The ASC-4 Solar for stand-alone applications also comes in a cost-effective version without the powerful M4 power management module.
Plug’n’play HMI touch screen
For improved user-friendliness, we’ve even created a plug and play touch screen display for hybrid projects. It’ll present all relevant data to you in real time, for instance power metre and inverter readings, PV penetration/performance ratio and much, much more.
Designed specifically to serve as a reliable, fully integrated and optimising link between sustainable power plants (fitted with for instance PV solar inverters and battery inverters) and diesel genset power plants, DEIF’s automatic sustainable controller, ASC-4, is a new, market-leading solution for the industry.
