- Page 5 BFS-A1 INSTALLATION DIAGRAM One BFS-A1 will control two solar panels and by series connection of the BFS, multiple solar panels can be connected to from a greater capacity system. The diagram below illustrates a typical example of a BFS protected installation using six solar panels and three BFS-A1.
- Page 6 *Water resistant end stop - Insert the two red sealing plugs in to the Communication Superseal plug(supplied) and connect to the DC output connector of the last BFS-A1 in the series in stallation.If only a single BFS-A1 is used then this patr is still used to seal the DC output connector.
