Solar inverter destruction and module degradation - reasons, effects and solutions!
Since the last three years the internet is full of reports of solar inverter disturbances, fails, destruction, replacement activities, as well as of callback activities of different well-known manufacturers. In Spring 2013, like in the years before, new SWR explosions with fire occurred and they had their cause in capacitor problems.
German example of one numerous internet reports on that problem:
Extincting those fires is a very dangerous work for the fire workers.
For the owner of the device a failure always means loss of money and much effort to correct it. Often the PV / solar inverter devices have been financed via loan of money, which have been adapted to the potential SWR value. Additional, costs for device failure are not included and insurances often do not pay them either.
