Bosch BPT-S series single-phase string inverters

The Bosch BPT-S single-phase string inverters for photovoltaic systems feature communications interfaces that allow quick commissioning and simplified remote analysis, as well as a transparent overview of data.

The range includes the BPT-S 3 and 3.68 inverters that come with one Ethernet RFID interface, one DC connection, weigh 17 kg and have a maximum output current of 13 and 16 A respectively. The range also includes the BPT-S 4 and 4.6 inverters that come with two Ethernet RFID interfaces, two DC connections, weigh 25 kg and have a maximum output current of 17.4 and 20 A respectively.

All inverters in the range have LED backlit screens and use touchless technology that can be used to navigate the menu using gesture controls or by an e.Key the size of a credit card. The integrated data logger function can record all data and makes it available in graphical form in the e.Web monitoring portal. A visualisation is possible on smartphones with the e.UserApp.

The wide entry voltage range of 170 to 750 V also ensures flexibility in the planning of the PV generator. The number of MPP trackers is optimally set to the performance of the solar modules. To ensure operational safety, an intelligent service switch will automatically disconnect the PV generator from the inverter if there is a fault during operation.

The inverters also feature a maintenance-free cooling concept, PowerCool, which optimises the heat distribution of the inverter.
