Optimise where necessary — otherwise pass it through

BRC Solar GmbH, based in Ettlingen, offers PV optimisers. The devices are mounted on the module and balance out power differences within a string, ensuring that a weaker or shaded module does not determine the yield of the entire string.

The difference compared to conventional optimisers: according to the manufacturer, the power electronics remain inactive as long as no optimisation is required (patented inactivity of the power electronics). The optimiser only activates in the event of shading and adjusts the current and voltage of the weaker module to match the string; according to the manufacturer, this prevents the module’s bypass diodes from triggering.

No system dependency, no additional bus

The optimisers can be used independently of the inverter and require no additional communication components. The system architecture therefore remains as simple as it would be without optimisers — even when retrofitting existing installations. Those requiring transparency can add the BRConnect gateway. It reads data from the M600-M optimisers via the DC line (powerline, not via radio) and displays the data at module level.

BRC Solar at ACTEC

ACTEC stocks BRC Solar optimisers for private customers and specialist installers. These are particularly useful wherever roof surfaces are irregular: dormers, chimneys, mixed pitches, neighbouring buildings — situations in which entire sections of the roof would otherwise remain unused.
