EMS controller
With the HYBRID BASIC controller, elgris offers an easy to use, but high quality control system targeting single generator applications. The unique features of the elgris controller define new standards in term of commissioning time, durability and performance.
Based on the in-house developed HYBRID control algorithm, the elgris controller determines the operating point of a single generator and adjusts the photovoltaic system accordingly. Due to the universal layout and standardized communication protocols and interfaces, a wide range of inverters are supported.
With the elgris HYBRID BASIC controller, almost any generator can be upgraded with any PV-system thus reducing power and safe on fuel.
The elgris HYBRID BASIC controller measures single phase the actual power supplied to the load by the generator and multiplies this number by three for all phases.
When the load of the generator is below a user defined threshold level, the controller will automatically reduce the power output of the photovoltaic to increase the load of the generator.
When the load of the generator is still lower than the minimum threshold level, the photovoltaic is disconnected to prevent the system for instability and protects the generator for reverse current.
At night, or when the actual power of the photovoltaic is very low (due to clouds etc), the load is supplied by the generator. With the HYBRID BASIC controller it is not possible to switch of the generator.
With the HYBRID ADVANCED controller, elgris offers a platform for a high quality control system targeting multi generator applications starting at 150 kVA or single generator applications starting at 250 kVA. The unique features of the elgris controller define new standards in term of commissioning time, durability and performance.
Based on the inhouse developed HYRBID control algorithm, the elgris controller determines the operating point of the generator(s) and adjusts the photovoltaic system and/or generator accordingly. Due to the universal layout and standardized communication protocols and interfaces, a wide range of inverters is supported.
The inverter set point is calculated in real-time and adjusts with a high resolution to optimize photovoltaic outputs and thus increase savings.
With the elgris HYBRID ADVANCED controller, we offer a universal, scalable solution targeting customers in the field of production, mining, construction and other areas where most power is being consumed during daytime.
The elgris HYBRID ADVANCED controller measures true three phases the actual power supplied to the load by the generator in real time.
When the load of the generator is below a user defined threshold level, the controller will automatically reduce the power output of the photovoltaic to increase the load of the generator.
When the load of the generator is still lower than the minimum threshold level, the photovoltaic is disconnected to prevent the system for instability and protects the generator for reverse current.
At night, or when the actual power of the photovoltaic is very low (due to clouds etc), the load is supplied by the generator.
With the HYBRID ADVANCED controller it is possible to include a storage system like
batteries and shut down the generator when there is a surplus of solar energy.
This reduces fuel consumption and also maintenance costs of the generator.
