We provide the platform.
You scale your energy business.
At record speed.


The future of energy is decentralized, digital, and green. With KiwiOS X, we have developed a software platform that enables your company to connect, monitor and optimize the multitude of assets, systems and partners that a decentralized energy system relies on. Based on a transparent and flexible platform-as-a-service model, your company can connect your own energy applications to KiwiOS X via standardized APIs and in this way enrich them with more data and functions.

Who is KiwiOS X designed for?

Maximum flexibility, minimum complexity


Kiwigrid is opening up its energy IoT platform to companies that already have existing applications or want to develop new ones. These companies can develop their own custom applications according to their own ideas. And they can do so without having to take responsibility for the complex infrastructure setup and maintenance normally associated with developing and launching an energy IoT application. Our customers thus retain control over their unique features and user interfaces that represent their brand and differentiate them from the competition.

Specific APIs for each device class independent of manufacturers and protocols

Ready-to-use building blocks for maximum development speed

Proven scalability and availability of 220.000 connected energy assets

How does our platform-as-a-service model work?

Kiwigrid supplies its customers with the kit and various building blocks. Customers can then assemble these building blocks according to their own ideas and use them to build their own individual applications. With the help of the building blocks, customers can easily develop and run their own apps within a few days or weeks, depending on the complexity. No matter what our customers build based on our APIs, everything is always underpinned by our KiwiOS X platform and is accordingly robust and secure. KiwiOS X API calls are billed in a very transparent pay-per-use pricing model.

Energy IoT done right

KiwiOS X at a glance

Specific APIs for each device class independent of device manufacturers and protocols

With our KiwiOS APIs, we adhere to standard technologies, which ensures better interoperability and easier integration of new devices, significantly reducing development and maintenance costs. KiwiOS X APIs provide turnkey connectivity to PV systems, electricity storages, wallboxes and heat pumps from a wide portfolio of market-leading manufacturers. Thereby, KiwiOS X acts as a neutral platform that does not compete with device manufacturers. This not only makes technical device integrations obsolete, it also eliminates the time-consuming process of establishing and maintaining numerous device partnerships with manufacturers.

Turnkey functional modules from device integration to energy optimization for maximum development speed

While most competitors offer "one API for everything", Kiwigrid provides specific APIs optimized for PV/hybrid inverters, electricity storage, charging infrastructures, heat pumps and meters. APIs for smart tariffs and flexibilities will follow in future development stages. The advantage: companies only pay for those API calls whose device domain is actually connected in the field. This device-specific pay-per-use principle can only be implemented with a mixed API across all device classes at great expense. The "KiwiOS X" APIs not only provide the raw data points of a PV inverter or an EV charger, but also offer endpoints for higher-value functions such as KPIs or load curves. In a future stage of development, even turnkey energy management algorithms will be usable via an optimization API.

Proven scalability and availability of 220,000 connected energy devices

The new platform generation KiwiOS X is not the result of a venture capital driven startup, but a mature system with over a decade of experience in developing and operating a wide variety of energy IoT applications. This includes valuable learning curves in dealing with typical error patterns and manufacturer-specific problems in integrating and controlling energy devices. Today, KiwiOS X processes over 7 billion data points daily from over 220,000 connected energy devices across Europe. Customers can rely on a platform availability of at least 99.5%.

Highest level of security thanks to certifications and ten years of expertise

KiwiOS X meets the highest security requirements: Firstly, the system is fully integrated with the Google Cloud, whose services meet the C5 standard issued by the German Federal Office for Information Security (BSI). Secondly, Kiwigrid has years of experience, in-house expertise and processes for developing the smart meter gateway in accordance with one of the world's most stringent certification processes in line with the international Common Criteria EAL 4+ security standard. Among other things, Kiwigrid has implemented an ISO 27001 information security system in the organization for this purpose. Thanks to this wealth of expertise, KiwiOS X reduces operational risk and avoids expensive cost traps.

Standardized and forward-looking technologies thanks to Google Cloud

The full integration of KiwiOS X with the Google Cloud offers Kiwigrid customers significant benefits for the speed of development and scalability of their applications. The Google Cloud offers one of the most scalable and open infrastructures for cloud computing, data analytics and machine learning among all public clouds. The high level of standardization of the Google Cloud, combined with its mass distribution worldwide, also opens up the possibility for KiwiOS X to easily connect with platform services from other public cloud providers and on-premise environments. For example, KiwiOS X enables cloning of infrastructure and services to allow customers to expand into data centers around the world.
