950-SPT1 Solar PV Troubleshooting Learning System by Amatrol

Installing a solar PV system is one skill. Keeping it running, diagnosing faults when it underperforms, and troubleshooting the increasingly complex AC, DC, and grid-connected configurations that modern solar installations use is an entirely different set of skills, and one that is in even shorter supply than installation competency. Solar systems are long-lived assets whose owners expect them to perform for twenty or more years. When something goes wrong, a technician who can diagnose a charge controller fault, identify a failing inverter, trace a wiring problem in a combiner box, or isolate a battery bank issue is the person the industry needs, and the person that employers across the solar sector are competing to hire.

The Amatrol 950-SPT1 Solar PV Troubleshooting Learning System develops exactly those skills. Through a unique combination of interactive multimedia eLearning curriculum and hands-on experience with a full suite of real industrial solar PV components, the 950-SPT1 teaches students to connect, operate, program, and troubleshoot AC, DC, and grid-connected solar PV systems at both the component and system level. The system supports portions of the NABCEP Certified Solar PV System Installer certification, connecting classroom training directly to the industry credential that solar employers recognize.

Klein Educational supplies Amatrol alternative energy training systems to CTE programs, community colleges, and technical training centers across California, Oregon, Washington, Arizona, Nevada, Hawaii, and Alaska. As the only authorized Amatrol distributor in these seven states, we help programs get the right system configured and running.

What is the Amatrol 950-SPT1?

The Amatrol 950-SPT1 Solar PV Troubleshooting Learning System is a mobile workstation built around a wide variety of industry-standard solar PV components that give students hands-on experience with the actual systems they will troubleshoot in the field. The workstation includes component panels with breakers, a combiner box, an MPPT charge controller, a micro-inverter, a grid-interactive inverter, a programmer, a communications gateway and hub, lamps, batteries, and meters, covering the complete range of components found in both off-grid and grid-connected solar PV systems.

The inclusion of both a micro-inverter and a grid-tie inverter is an important feature that distinguishes the 950-SPT1 from more limited training systems. Both inverter types are required to teach troubleshooting skills across all major types of AC solar PV systems, including stand-alone AC, grid-connected AC, and grid-connected AC with battery storage. Modern solar installations frequently include network communications between system components, and the inverters and charge controller on the 950-SPT1 allow students to learn how to network system components and troubleshoot at the system level as well as the component level.

Electronic fault insertion

The most important troubleshooting training feature of the 950-SPT1 is Amatrol's electronic fault insertion system. The system is equipped with a wide array of electrical faults that allow instructors to replicate realistic component and system-level failures with precision. Electronic fault insertion is specifically superior to mechanical fault methods for several reasons.

It prevents component damage during fault training, which is a significant advantage given the cost of solar PV components. It allows instructors to track each student's troubleshooting progress in real time, identifying specific areas where the student's diagnostic approach breaks down and targeting those areas with additional instruction. It allows faults to be set up in advance, enabling students to perform self-directed troubleshooting study when appropriate rather than requiring an instructor to be present for every exercise. And it allows instructors to repeat the same fault scenario as many times as needed across different students without any equipment wear or preparation time.

This electronic fault capability is what transforms the 950-SPT1 from a system demonstration trainer into a genuine troubleshooting skill development platform.

What students and trainees learn

The 950-SPT1 curriculum covers the full range of solar PV troubleshooting knowledge and hands-on skills that technicians need across DC, AC, and grid-connected system types.

PV module and array topics cover PV module operation and performance characteristics, series and parallel array connections and their effect on voltage and current output, PV array station setup for both indoor and outdoor use, and array performance measurement and analysis.

Solar battery topics cover battery operation and chemistry, battery bank configuration in series and parallel, battery bank output calculation, charge controller operation and programming, and battery system troubleshooting.

DC solar PV system topics cover DC system connection and operation, charge controller configuration, system performance measurement, and DC system-level troubleshooting.

AC solar PV system topics cover stand-alone AC system connection and operation, micro-inverter installation and configuration, grid-connected AC system connection and operation, grid-interactive inverter programming and configuration, and AC system-level troubleshooting.

Grid-connected system topics cover grid interconnection requirements, net metering concepts, grid-tie system operation monitoring via the communications gateway, performance analysis using system monitoring data, and grid-connected system troubleshooting.

Component-level troubleshooting covers the systematic diagnosis of faults in PV modules, combiner boxes, charge controllers, inverters, batteries, and wiring connections using appropriate test equipment and diagnostic procedures.

System-level troubleshooting covers diagnosing performance problems that span multiple system components, interpreting system monitoring data for diagnostic purposes, and developing the systematic approach to fault isolation that efficient solar troubleshooting requires.

Multimedia eLearning curriculum

The 950-SPT1 includes Amatrol's interactive multimedia eLearning curriculum covering solar PV troubleshooting topics using text, audio, video, interactive quizzes, and 3D animations. The curriculum teaches both the foundational knowledge and the practical hands-on skills students need to troubleshoot the most common solar PV systems, with each theoretical concept paired directly with a hands-on application task on the 950-SPT1 workstation.

The highly interactive format supports multiple learning styles, with voiceovers of all text, 3D animations illustrating system operation and fault scenarios, and interactive exercises that verify comprehension before students advance to hands-on practice. A Student Reference Guide compiled from the curriculum's technical content is included with the system, giving students a permanent condensed reference for use throughout their career.

Solar PV Array Station (95-SPA1)

The 950-SPT1 requires the Solar PV Array Station (95-SPA1), which adds multiple solar panels to enable students to work with realistic series and parallel array connections. The mobile array station is equipped with both a sun simulator for indoor use and the ability to operate outdoors with real sunlight on favorable days, giving programs the same indoor-outdoor flexibility described in the 850-AEC system. The array station allows instructors to take advantage of sunny days for outdoor training without needing to move the entire 950-SPT1 workstation.

NABCEP certification preparation

The 950-SPT1 supports the knowledge needed for the NABCEP Certified Solar PV System Installer examination, the primary industry-recognized solar PV credential in the United States. Programs that use the 950-SPT1 alongside the 850-AEC Alternative Energy Learning System and the 950-SPF1 Solar PV Installation Learning System build a complete solar PV education pathway covering foundational theory, hands-on installation, and advanced system troubleshooting that comprehensively prepares students for the NABCEP certification process.
