pvServe
PV Service Power Supply
Portable PV service power supply for backfeed testing, thermography, and inverter commissioning.
The pvServe service power supply is a multifunctional tool designed for PV installers, electrical contractors, and inspectors working on photovoltaic system testing and maintenance. With a freely adjustable output voltage of 0–1000 V DC, up to 5 A current, and a maximum power of 3.3 kW, the unit enables controlled backfeeding of PV strings using a standard 230 V AC outlet (16 A). The device is ideal for backfeed thermography, allowing hotspot detection without requiring solar irradiation. Measurements can therefore be performed independently of weather conditions — even at night. It also supports electroluminescence testing, making it possible to detect microcracks and defective bypass diodes in solar modules. Additional applications include bypass diode testing, inverter commissioning without an installed PV generator, and controlled snow melting by feeding current into PV modules. Operation via an integrated graphic display ensures practical and intuitive handling in field service environments. With its robust portable design and weight of approximately 18.5 kg, pvServe is an ideal solution for on-site photovoltaic service and maintenance work.

pvServe: Multifunctional PV Service Power Supply for Professional Diagnostics and Maintenance of Photovoltaic Systems
The pvServe is a highly precise service power supply for the technical inspection, troubleshooting, and maintenance of photovoltaic module strings. It was specifically developed for solar installers, electrical contractors, surveyors, and service teams who need to test PV strings reliably and independently of current solar irradiation.
Thanks to grid-coupled reverse current injection, the system operates safely and reproducibly even at night or under low irradiation conditions. With up to 1000 V DC, 5 A output current, and 3.3 kW power, the pvServe is ideally suited for mobile field diagnostics, preventive quality assurance in solar parks, as well as laboratory and commissioning applications.
Key Advantages for PV Diagnostics
Typical Application Scenarios
Targeted current injection to visualize thermal anomalies such as hotspots, corroded cell connectors, or defective junction boxes.
In combination with a suitable camera, microcracks and structural defects in solar cells can be made precisely visible.
Validation of protective diodes to detect partial failures, power losses, and safety-relevant fault conditions.
Electrical function testing before roof installation is fully completed, helping reduce project time and improve trade coordination.
Targeted heating of the module surface for snow removal under suitable roof inclinations and controlled operating conditions.
Ideal for ground-mounted systems, rooftop installations, and mobile testing tasks during maintenance, inspections, and fault localization.

Configuration and Capacity Options
At maximum voltage utilization up to 1000 V, up to 19 modules with 72 cells can be tested in series.
For 60-cell modules, up to 22 units can be powered and diagnosed in series.
At the full current of 5 A, a maximum voltage of 660 V is available, which is suitable for many service and diagnostic tasks.
In 5 A operation, up to 12 modules with 72 cells or up to 15 modules with 60 cells can be tested.
Integration and Operational Safety
Added Value for Industrial Users
The pvServe optimizes maintenance and diagnostic processes in photovoltaic systems through reproducible testing independent of weather conditions and time of day. Service operations can be planned more effectively, while daytime energy generation remains as unaffected as possible.
In addition, the system supports early fault detection, documentation of critical defects, and the parallelization of electrical and mechanical project phases. This helps reduce yield losses, shorten project timelines, and provide technically sound support for warranty claims.
