Ideally suited for greenfield hybrid power plants, the ASC-4 Solar
controller can interface with other DEIF controllers and a wide
range of PV inverters, enabling you to integrate solar power in
greenfield applications and maximise sustainable power penetration.
The ASC-4 Solar is a reliable, fully integrated, and optimising
link between sustainable power plants and genset power plants.
Designed for greenfield applications with other DEIF
controllerssuch as the AGC-4 MKIIadvanced genset controller and
other sustainable controllers in the ASC-4 range, the controller
can interface with PV inverters and other power source controllers,
and it can be part of a power/energy management system.
Maximising sustainable power penetration:
In any operation mode, the solar controller automatically maximises
sustainable power penetration, depending on the total load demand
on the hybrid plant, without compromising constraints such as
minimum genset load demand.
In off-grid operation, the ASC-4 Solar offers a minimum genset load
constraint that lowers sustainable power penetration if PV
production is compromised. This ensures a certain amount of load on
the gensets, eliminating the risk of reverse power situations and
impure combustion and exhaust problems.
Ideal for self-consumption applications:
In grid-tied applications, the ASC-4 Solar can feed surplus PV
energy to the grid and generate profit in accordance with grid
operator feed-in tariffs. Alternatively, it can regulate production
through PV curtailment to match the self-consumption, thereby
preventing any feed-in of PV power to the grid (zero export) if
prohibited by grid operator regulations.
Wide range of inverters:
The ASC-4 Solar is compatible with a wide range of PV inverters,
allowing you to integrate it with virtually any PV installation.
DEIF is a member of the SunSpec Alliance, and new inverters are
constantly being added. For an updated compatibility list for the
controller, see Application Notes on the Documentation tab.
Compatible with sky imager solutions:
The ASC-4 Solar is compatible with leading sky imager solutions,
enabling it to predict the weather and PV production and take
counter-measures if needed, for example starting up the required
number of genset in due time before clouds reduce PV production –
and keeping gensets running if forecasts indicate that PV
production will drop again shortly.
Emulation feature provides safe system testing:
The built-in emulation feature of the ASC-4 Solar enables you to
interact with the controller in a controlled and safe environment
without risking to damage any equipment. All you need to do to
perform a complete test of your system is to turn on your
controller and connect communications.
