Examples
Here is a selection of examples so that you can get a practical idea of our solutions. They will give a small insight into the extremely diverse possibilities of our all-in-one monitoring and control solutions.
Germany: Combining PV Monitoring, Energy Management and Consumption Monitoring
This combined PV and battery storage system has been implemented in Fulda, Germany. It integrates a PV system and two battery storage systems. The system was developed to reduce energy costs and increase self-consumption.
By integrating all components within the system, the operators can benefit from the efficiency of renewable energy while ensuring reliability and flexibility through the battery storage units.
The challenge in this project was to combine the existing PV system with two different battery systems and include a detailed consumption monitoring. The monitoring and control system needs to make sure that all components are integrated and interact with each other.
With a self-consumption optimization feature, it is possible to effectively utilize surplus solar energy by directing it into immediate energy consumption or storing it for later use, instead of exporting it to the grid.
The peak shaving system allows for the effective use of batteries during high load periods to reduce power drawn from the grid.
An advanced PV analysis feature allows for close monitoring of the PV system’s performance, comparing actual output with expected values to identify and address potential deviations early. This ensures that the PV system operates at its optimal efficiency.
EcoPhi was chosen for its highly flexible solution which can integrate and orchestrate multiple different components such as several batteries within a single system. Additionally, we combine detailed energy data monitoring with sophisticated control mechanisms.
The Netherlands: Monitoring and Control of an Agri-PV system
With the growing importance of sustainable energy solutions, Agri-PV systems are becoming increasingly significant. These systems not only contribute to renewable energy production but also support agricultural activities by providing an efficient use of land.
Agri-PV systems require effective monitoring and control to ensure optimal performance and energy efficiency. The integration of solar in agricultural settings presents unique challenges and opportunities, making it essential to have a robust system for managing both energy generation and agricultural productivity.
The solution needs to monitor and control various components such as inverters and PV trackers. These components need to work seamlessly together to maximize energy generation and ensure reliable system performance. Also, a number of sensors for measuring energy and agricultural parameters need to be included to enhance system efficiency and crop management.
On-site Control:

This flexibility and technological expertise make us the ideal partner for innovative and sustainable energy projects.
South Africa: Monitoring and control of a hybrid PV system
This combined PV and genset system has been implemented in Johannesburg, South Africa. It combines a 500 kWp PV system and two 600 kVA diesel generators. The system was developed to reduce energy costs and bridge power outages. By integrating both components within the system, the operators can benefit from the efficiency of renewable energy, but also ensure reliability and flexibility during power cuts due to the diesel generators. This enables a continuous power supply while helping to reduce dependence on traditional power sources, which is particularly beneficial in regions with unreliable power supplies.
The challenge in this project was to combine both the existing PV system with two different diesel generator types and control the overall system. The monitoring and control system needs to make sure that all components are integrated and interact with each other. The system includes different controls over different components: The grid feed-in must be limited and the generators have to run in fuel saving mode, yet the system must not be interrupted during power cuts.
With our zero-feed-in system, you can effectively use the surplus solar energy generated by feeding it into your own energy consumption or storing it instead of feeding it into the grid. Our target/actual PV analysis allows you to closely monitor the performance of your PV system and compare it with the expected values in order to identify and rectify potential deviations at an early stage. In addition, with our Fuel Saver feature, we offer an intelligent solution for optimizing the fuel consumption of your diesel generators by efficiently adapting operation to the current energy demand.
EcoPhi was chosen because our monitoring and control solutions are flexibly adaptable and compatible with different inverters and other components like generators – also within a system.
The Netherlands: Energy management system with dynamic prices
Combining multiple components within one system can increase complexity but gives the potential to optimize the system. With dynamic prices based on the intraday or day-ahead market, the economical value of such systems can be highly increased. Therefore, a modern and flexible Energy Management System is necessary.
System: Solar Edge, EV Chargers, Day-Ahead Price
Combining different components within one system such as inverters, battery storage, EV chargers or heat pumps means that different communication protocols and standards must be implemented. Different priorities and regulations also need to be included, such as prioritization of specific EV chargers or feed-in regulations. Controlling and optimizing the whole system based on the volatile energy market is complex, but offers great savings potential.
We used our all-in-one solution with hardware and software. The hardware is easy to install and can be connected to different components at the same time. We used Feed-In Limitation (due to regulatory constraints), peak shaving, self-consumption optimization and dynamic price integration to optimize the system.
EcoPhi was selected because our monitoring and control solutions are highly adaptable and compatible with various inverters, storage systems, EV chargers and heat pumps within the same system. As we are able to control complex systems based on dynamic prices, we are a perfect fit for such systems.
South Africa: Optimizing a PV + battery system
This combined solar and storage system has been installed at a school in Cape Town. It has been built to make sure that the school is always supplied with energy, also during load shedding hours (scheduled power cuts in South Africa).
System:
PV: 125kWp SMA
Storage: 400kWh Atess
The system consists of a PV and storage component that are not able to communicate directly. Also, several controls need to be combined such as peak shaving, self consumption optimization and feed-in limitation.
Our installed hardware combined with our cloud platform makes sure that the system is operated and optimized.
Features of the installed Energy Management System include:
- Peak shaving
- Feed-in limitation
- Self consumption optimization
Along with the EcoPhi solution, several other options have been evaluated. EcoPhi was chosen because our energy management system stood out due to its flexibility and competitiveness in terms of economical value.
Emerging markets: Reducing food waste with efficient solar powered cold rooms
Many countries, particularly on the African continent, have a large rural population, a focus on agriculture and limited energy infrastructure. Here, self-sufficient solar-powered refrigerated containers are of great importance. They can also be used to cool food in areas without electricity, thus reducing waste.
EcoPhi monitors the systems and ensures optimum operation thanks to the integrated control system.
The inverters used include SMA, Growatt, Steca, Felicity and Victron
The systems are often located in remote regions with sometimes extreme climatic conditions. The systems themselves are complex, as in addition to the off-grid PV system for energy generation, other relevant components have to be connected, monitored and controlled, such as different cold storage units, air conditioning units or security cameras.
Another challenge is that different inverters are used.
On the hardware side, a “Plant Controller” is used to monitor and control even complex systems. Various analog and digital sensors and actors can be connected to it. The cooling system is controlled depending on the room temperature.
Depending on the system size and location, different sensors and features are used. These include:
- Irradiation indicator
- Door sensor to show when the entrance doors are opened
- Temperature and humidity sensors
- Security camera to monitor the cold room interior
Our monitoring and control solutions effectively connect complex systems in terms of both hardware and software. Individual control conditions can be created individually. Our hardware also works with international or local SIM cards and also transmit data in areas with weak signal. This combination makes us the ideal partner for this systems where not only the energy generation but also the application focus must be taken into account.
