Battery and system controls closet for WPI Solar and wind turbine system. All power from the panels and wind turbine come into this closet and go out the Inverter in the Innkeepers apt and/or the DC loads (mostly the Inns two electric refrigerators (both are 24V DC)). There are also some small lilghting loads that are run through a converter box that steps down the 24DC current down to 12 V. This was done because - at the time - much of the lighting available was 12V and not 24 and this is because much of the lighting availble was taken from the RV world where most of it is 24 V.
