Overview of all components

The low cost failure and yield monitoring system for plants with a maximum power of 10 kWp.

The Solar-Log 250 is compatible with inverters from all the major manufacturers. One inverter with a load output of 10 kWp and up to three MPP trackers can be connected.

Inverter Interfaces

The inverter can be connected via RS485/422 or an Ethernet connection. A meter can be set up as an inverter via the S0 interface and records the output from incompatible inverters.

Solar-Log 250 USB Connection and Data Export
A USB stick can be connected for safe and quick manual installations of new firmware updates, data enhancements and system add-ons.


More than just Pulse Metering
Pulse Metering devices provide production data; is this really sufficient to make sure the PV plant operates properly? We say no. The number of more than 243,000 PV plants equipped with Solar-Log™ data loggers worldwide confirm this.

Solar-Log 250 compared to Pulse Metering - some differences

Solar-Log™ Pulse Metering Info
