LOGR-S Data Logger

The LOGR-S Data Logger is an advanced data logging system that is purpose-built for solar resource monitoring on operational utility-scale PV plants.

LOGR-S Embedded Configuration Software

Details

LOGR-S is NRG Systems’ first data logger designed specifically for the solar energy industry. Based on decades of data logger development and manufacturing experience, LOGR-S features the same user-friendliness that has come to define NRG’s data logger line, while satisfying the increasing demand for reliable, high-quality solar resource measurements on operating PV plants.

LOGR-S integrates seamlessly with NRG’s Solar Resource Monitoring (SRM) System, allowing users to plug into their plant’s SCADA network with ease. LOGR-S’ modular design can also be adjusted to accommodate a project’s unique measurement requirements. Additionally, LOGR-S features:

compatibility with the most commonly used SRM sensors
high-resolution, high-accuracy analog measurements
built-in and optional PV input module for soiling measurements
configurable serial measurement capability for data acquisition from digital sensors
integrated communications capabilities
storage capacity for historical real-time data
automated delivery of historical data

LOGR-S is supported by our expert Technical Services team who can assist our global customers via in-the-field and remote trainings, installation assistance, and more.

Benefits

High-utility data logger and real-time sensor interface for solar resource monitoring
Purpose-built, modular platform delivers straightforward functionality
Flexible and scalable design accommodates each project's unique requirements
