For the first time, the product standard defines technical requirements for plug-in solar devices – also known as balcony power plants and guerrilla PV – as a complete system. The preliminary standard is primarily aimed at anyone who develops, manufactures, and sells plug-in solar devices. Manufacturers and suppliers of such products will now know exactly which technical requirements they must meet. Testing organizations can use the standard to check conformity and thus safety.
Among other things, the product standard also includes the option of connecting via a standard protective contact plug, which was not previously permitted. To ensure that this can be done safely, additional requirements have been defined, e.g., for the shutdown time of the inverter when the mains plug is pulled out.
The experts at the VDE Institute carry out the following tests on plug-in solar devices, among others:
- Testing of modules in accordance with IEC 61730
- Testing of inverters in accordance with IEC 62109
- Certification of grid conformity according to VDE-AR N4105
- Testing of the mounting frame
- Testing of the plug connections used
- Testing of cables and wires
