e.manager mc version 2 - The cost-effective self-consumption manager

The e.manager mc version 2 is the ideal and cost-effective solution for monitoring the domestic photovoltaic system and optimizing its self-consumption. The integrated contactless power measurement turns the e.manager mc into a full-fledged smart meter with bidirectional metering and PV system monitoring.
For this purpose, the e.manager mc has 1xRS485 interface, 4xUSB, 4xinputs for cable conversion transformers (secondary 50mA and 1A) and 3xinputs for voltage measurement on all phases. 4 digital inputs allow the connection of ripple control receivers, S0 current meters or other digital switching contacts. In addition, the e.manager mc version 2 expansion sockets provide the necessary flexibility to realize your very individual measurement and control tasks in the field of photovoltaic system monitoring, energy management, heating technology and home automation.

The inverters and other components (electricity meters, sensors, Modbus devices) can be easily integrated and controlled via the RS485 or network interface.

  • Professional monitoring and control of photovoltaic systems and other renewable energy generators
  • Optimization of own consumption and the 70% control
  • Extensive evaluation and control options
  • Reliable yield due to extensive error analysis and alarming options
  • Worldwide data retrieval possible
  • Free portal portal.enerserve.eu
  • Suitable for all system sizes

With the e.manager mc you can easily create rules to control consumers, battery storage, heat pumps and heating cartridges. So you can maximize your own consumption and save costs.
