Deploy-it-yourself control software.
Renewable energy systems are being deployed at an incredible rate. Increasingly at a single site we see solar PV, wind turbines, battery systems, conventional generation and new technologies such as heat pumps and EV chargers.
That’s a lot of different devices and technologies. They need to be coordinated and you’ll want to view the entire system at a glance. That’s why we’ve built an integrated control and cloud solution to help you get the most out of your hybrid energy system.
All we need to do is connect the dots.
The technologies we need to quit fossil fuels are here today.

Hybrid power is becoming the norm.
Economics
Dramatic solar and battery price decreases.
Congestion
Massive deployment has brought the grid to its limits.
Much more hybrids
Solar plus battery, battery plus EV charger, heat pumps, generators, electrolysers.
H.E.A.T. builds hybrid control software.

We help you do this
Upskill your organization with our online training academy. Increase your value-add.

Core Logic
Batteries are flexible.
Heat pumps are flexible.
EV chargers are flexible.
Renewable generation is flexible.
We make them work as a team. Reliably.
The core logic has two tasks:
Enforcement of device limits.
Fully automatic enforcement of predetermined system and grid technical limits.
Prioritization of use
Rule-based decision making to achieve commercially optimal operation.
Our controller covers all mainstream technical applications:

Interfaces
Understand and observe your system.
Human interfaces and technical interfaces.
User interfaces
Web-based user interface allows you to monitor, control, and parametrize your system.
Controller
Vendor Layers
Vendor layers allow us to communicate with the specific vendor devices in your project.
Our web-based UI

Parametrization
You take over software parametrization. We support you with training.
Our training
Hybrid power systems deep dive.
PV inverters can be purchased off the shelf and installed by a trained electrician. But there is no such training for hybrid system controls.
You can purchase our software off the shelf, and we provide the training — not just about our product, but about the fundamentals of hybrid power systems.
Practical
Simulation and real world
Application knowledge
Using user interface
Foundational Knowledge
Kirchhoff’s current law, energetic concepts
Our academy
A standardized methodology.
Comprehensive training empowers solution providers to deploy systems by themselves
