The simple plant monitoring system for smaller house installations
Easy to install
The Solar-Log200 is designed without a built-in display. It is
connected to the inverter using a RS485 interface; the data from
the plant monitoring system is supplied to the local network or to
the internet via an ethernet interface. The web-based software
makes configuration especially simple. The Solar-Log200 is
compatible with all popular inverter manufacturers.
Alarm function and performance comparison
No more losses due to unnoticed failure of individual strings or
the entire plant: The Solar-Log200 sends out alarms automatically
via email or SMS. Daily yield notifications are also possible.
Furthermore, all status and error messages can be conveniently
called up from any web-enabled PC.
As for all Solar-Log™ devices, the Solar-Log200 also contains
web-based evaluation software. Performance data for individual
strings can be compared as can output from other plants (optional).
Secure and upgradable
The Solar-Log200 possesses integrated memory for data logging.
Furthermore all of the data can be saved manually on the local PC
or automatically on a homepage. Subsequently incorporating it into
an existing plant is no problem either: Data can be manually added
For the Solar-Log200 we offer a comprehensive range of accessories
and enhancements. Applications for handheld PCs and iPhones offer
additional possibilities for monitoring and presentation in mobile
