There are many software controllers on the market. But only enwitec BRAIN combines
manufacturer-independent edge AI with ready-to-install control cabinet hardware
compliant with DIN EN 61439. Maximum profit margins for installers, 100% self-sufficiency for
your customers.
Top rating in the enwitec 2026 Market Comparison (in-house evaluation)
100% compliant with VDE-AR-N 4105 and §14a EnWG
Developed and manufactured in Germany
Many modern EMS systems outsource computing logic to the cloud. If the Internet goes down, the grid-optimized dimming pursuant to Section 14a of the German Energy Economy Act (EnWG) or dynamic charging stops. BRAIN performs 100% of its calculations locally on industrial edge hardware.
Piecing together individual relays, meters, power supplies, and gateways on the DIN rail takes up to 6 hours per system. enwitec delivers the BRAIN Cabinet fully assembled and ready for connection.
Inverter manufacturers block third-party storage devices ; wallbox providers require their own gateways. With enwitec BRAIN, you can seamlessly control all market-leading brands through a single system.

¹ This comparison is not based on data from an independent testing organization, but rather on enwitec’s own assessment based on publicly available manufacturer information (as of August 2026); values are subject to change due to firmware and product lineup updates.
Objectively evaluated based on installation complexity, interface openness, compliance with Section 14a
, and overall cost-effectiveness.
Pre-wired instead of on-site wiring
at the construction site
enwitec supplies the BRAIN Cabinet or the
PowerBackup BRAIN: fully wired,
type-tested in accordance with DIN EN 61439, including all
circuit breakers, terminals, and
surge protection. This significantly reduces
installation time compared to traditional
installation using individual components.
100% reliability thanks to
local edge AI
No latency, no dependence on third-party
servers, no mandatory monthly
fees. The BRAIN Controller
forecasts solar yield, household load, and
electricity prices (EPEX Spot / dynamic pricing)
directly on-site at the distribution panel.
Seamless Implementation of Section 14a of the Energy Economy Act (EnWG)
and Dynamic Rates
Control and dim heat pumps (SGReady/
Modbus), wallboxes (OCPP), and
home storage systems in compliance with regulations and
in a way that benefits the grid—via standardized
relay contacts or digital control commands.
At the same time, BRAIN optimizes electricity procurement
based on market prices.
Comprehensive emergency power solutions from a single source—
enwitec brings many years of experience in
automatic grid switching. The
system integrates seamlessly:
emergency power operation with true all-pole
grid isolation up to 30 kW and intelligent
load management in island mode.
Applications: Single-family and multi-family homes,
PV retrofits.
Heat pumps &
Wallbox without
Meter cabinet conversion.
Key Specs:

“In the past, we spent a lot of time coordinating individual components when integrating inverters, wall boxes, and heat pumps. With a preconfigured EMS in the control cabinet, installation becomes much easier and faster.”
TYPICAL SCENARIO
: Electrical Installation in a Single-Family Home
“In larger projects, interfaces between the EMS, the inverter, and other components can quickly lead to additional work. An open system architecture and standardized interfaces provide greater planning reliability in this regard.”
