pvServe is a power supply designed specifically to help solar specialists analyse photovoltaic systems. There are two established methods of inspecting solar modules without removing them: reverse current thermography and outdoor electroluminescence. Both methods involve feeding a reverse current into the solar array. The first method employs a thermal imaging camera to inspect the modules. The second method uses a special electroluminescence camera to carry out the inspection at night.
Sending a current in the opposite direction through the solar array requires a voltage that is higher than the no-load voltage of the actual array being tested. pvServe provides this function. The unit is portable and has been designed to take its power from a standard 230V AC outlet (no three-phase supply necessary). This makes it an essential part of the toolbox of every service technician who needs to troubleshoot PV systems.
