The Daystar MT5 Multi-Tracer
Our Daystar series of Multi-Tracers offer a complete solution for long-term testing of multiple photovoltaic modules. Modules are controlled independently and operated at their peak-power point. I-V curves may be taken at selected intervals, or manually. Average performance and weather data are collected and stored in daily files.

Each MT5 Multi-Tracer system consists of one Control unit and up to four Load units. The total power of the connected modules determines the required size of the Multi-Tracer system. Each Load unit is rated to dissipate up to 3,200 Watts. Connect four load units to one Control unit for up to 12.8 kW of total power dissipation.

MT5 systems are built to user specifications defining the number of module channels, voltage, current and power rating of each module channel.

Control units include 8 auxiliary voltage inputs that can be used to measure irradiance or other data. Control units include 24 thermocouple inputs standard and can be ordered with up to 56 thermocouple inputs.

Daystar Multi-Tracer History
Raydec, Inc. designed the first Multi-Tracer for the National Renewable Energy Laboratory (NREL) in 1993. We eventually collaborated with Daystar, Inc. to improve the design and offer the Multi-Tracers as a Daystar product.

We continued our relationship with Daystar, Inc continuing to refine and improve the Multi-Tracer through several versions up to the current MT5 systems.

In 2022, Daystar chose to end their 30+ years of successful operation. We are proud to continue to offer the same equipment directly to our customers. The hardware is the same reliable, high quality instrumentation we have strived to produce for decades.

The difference?

We are now selling our products directly to our customers and referring to it as the "Daystar model line" of products.
