A.4.1 Block Diagram of PL20/40 Hardware
The PL Controller is designed for common positive installations (i.e. switches solar and load in the negative wire).
It has a reverse blocking mosfet switch between the SOL- terminal and the BAT- terminal and a mosfet
switch between the LOAD- terminal and the BAT- terminal. There is also a low current mosfet switch
between the ‘G’ terminal and the BAT- terminal used to drive a generator control or alarm relay.
