STR-32G Sun Trackers
The STR-32G completes the extensive sun tracker range and is capable to take 60kg maximum load without compromising on precision.
The heavy-duty Sun Tracker STR-32G completes the extensive EKO Sun Tracker range and is capable to take the highest load without compromising the typical high precision and performance of the STR. Similar to the STR-21G/22G it features a fully automated set up procedure through a GPS receiver, providing increased reliability and enhanced functionality.
Even though the capacity load of the STR-32G is approximately 4 times more, the size hasn't changed. The most compact heavy duty sun trackers are perfectly suited to support all kinds of Global, Diffuse and Direct Radiation measurement sensors and spectroradiometers. Besides the standard EKO sensor mounts, various mounting options are available.
From sunrise to sunset the compact EKO Sun-Tracker guarantees accurate sun tracking and pointing of the attached solar sensors. The 2-axis tracker automatically adjusts to the sun’s position by the sun sensor closed-loop control system, even if the tracker is not oriented or leveled properly.
The sun-tracker comes standard with a mounting flange, the TRP-100 tripod is an optional extra. The 24 VDC low power consumption tracker can be powered by a solar-powered battery system or DC power supply. A wide range AC power adapter can be supplied to connect to the grid.
For over 20 years our clients who deployed the STR sun-tracker experience the ease of set-up, operating and reliable tracking.
