As an expert in energy management, Kiwigrid connects and certifies manufacturer-independent systems consisting of inverters, heat pumps, storage systems, SMGWs and wallboxes. Among other things, use cases for consumption optimization are tested according to dynamic tariffs.
Installing a PV system, a heat pump or a wallbox is a major investment. The full potential can only be realized when devices from different manufacturers are intelligently networked with each other in a system. Systems that have been extensively tested and certified by Kiwigrid offer the highest reliability.
What is a system certified by Kiwigrid?
Kiwigrid is manufacturer-independent. This means that Kiwigrid's energy management system (EMS) is basically compatible with the hardware of many different manufacturers and with dynamic tariffs from various tariff partners. All compatible devices and tariffs can theoretically be freely combined with each other. In practice, however, connectivity is somewhat more complex due to sometimes unpredictable interactions between devices. To prevent these potential compatibility problems, Kiwigrid has pre-certified a number of systems. These certified systems consist of devices from particularly reliable manufacturers with a high market penetration or a correspondingly high potential.
How are systems certified?
The systems are certified in special test laboratories. Systems with components such as inverters, electricity storage systems, EV chargers, heat pumps and smart meter gateways are set up there and tested in conjunction with the EMS. Among other things, use cases for maximizing self-consumption and optimizing energy consumption according to dynamic tariffs will be tested.
The hardware is provided by partners and customers and Kiwigrid takes care of the end-to-end testing. In the case of complex or innovative products, commissioning is often carried out jointly with the partners. The tests also check whether the devices are controllable – both in terms of power consumption (Section 14a EnWG) and feed-in (Section 9e EEG). Regulation commands from distribution network operators (DSOs) are simulated for this purpose. As soon as all tests have been successfully passed and the test documentation has been created, a system is considered validated.
The test duration is approximately one week, provided that connectivity has been established in advance. Only devices that meet certain approval criteria (e.g. housing, contact protection, technical documentation) are eligible for validation.
Advantages of certified systems
Certified systems offer numerous advantages. Thanks to the testing and validation carried out in advance, Kiwigrid can guarantee that the devices will work together smoothly as a system in practice. The certified systems also only contain devices that meet Kiwigrid's high quality standards.
End customers benefit from smooth connectivity of the devices in their household without having to worry about the configuration and compatibility themselves. Hardware manufacturers ensure proof of compatibility in accordance with §14a EnWG through validation, while hardware resellers can offer compatible systems in a targeted manner, which minimizes sources of error and simplifies installation.
Five different certified systems are currently available from Kiwigrid. The systems are designed for different use cases and expansion stages. Each of these systems connects different hardware components and links them with dynamic tariffs.
