Latest Patents
Wieser's latest patents include a method for controlling a solar power plant. This innovative approach optimizes the maximum power point of a solar cell stack, which consists of modules equipped with a Maximum Load Shutdown Device (MLSD) unit and an inverter. The MLSD unit is designed to shut down the module when the module voltage falls below a specified threshold and to reactivate it when a predefined voltage threshold is exceeded. The method involves defining and adjusting an electrical control parameter to ensure optimal performance, maintaining this parameter for a designated time, and determining the maximum stack power from current-voltage curves of the modules.
Another significant patent addresses a monitoring device for emergency standby operation. This invention determines the AC insulation resistance between the AC connections of an inverter and ground potential. During emergency standby operation, the AC connections are linked to an AC energy sink, allowing energy transmission from a DC energy source. An insulation test is performed, and the AC fault current is measured to calculate the AC insulation resistance.
