Full Control.
No Cloud Dependency.
The local hardware controller for your home. Connects inverters, batteries, and wallboxes. Secure, private, and independent.
The local hardware controller for your home. Connects inverters, batteries, and wallboxes. Secure, private, and independent.
Security is not a feature, it's the foundation.
Your consumption data never leaves your house. No analysis by third parties. The system continues to work even if the internet fails.
The interpreter for your tech. Connects Deye, Growatt, SolarEdge, Shelly, and many more into one local system.
Buy once, use forever. No monthly cloud fees for basic functions. An investment that stays.
You've invested in PV and batteries. Don't make yourself dependent on cloud services from overseas manufacturers now.
Simulation: Move slider to test PV surplus & load scenarios.
Compact technology, maximum freedom.
Measurement & Control.
No control without measurement. The system mandatorily requires two Shelly Pro 3EM units:
*Prices incl. VAT plus shipping.
Knowledge creates trust.
A2H-EMS is our premium hardware solution. You buy the device, the data stays locally with you, and there are no ongoing cloud costs for the basic functions.
Our A2H-EMS Mini Server (included in delivery). Additionally required: Two Shelly Pro 3EM at the grid connection point to measure import and export and for load.
Yes. This makes sense especially in combination with dynamic tariffs (Tibber, Awattar): Load the battery when electricity is cheap and use it when it becomes expensive.
The system protects your home connection. If the Wallbox, heat pump, and stove run simultaneously, the EMS regulates flexible consumers (e.g., the Wallbox) down temporarily to avoid tripping the fuse.
Using our temperature sensors, you can control all smart relays via temperature within the system. You decide flexibly: control only with PV surplus or also with grid power. Ideal for heating elements, ACs, etc.
You set your desired buy-price in the system. If the exchange price falls below that, the system automatically buys electricity and powers consumers like the Wallbox or hot water heater without overloading the house grid.
Yes (B2B). It solves the "incompatibility" problem. You can, for example, connect a Deye inverter with a Wallbox from another manufacturer at the customer's site.
