View into hutch from the top, right, front-facing door opening. The floor to ceiling wiring chase is visible along the back wall. The DirecTV insertion power supply and power outlet, a relay and wiring for the water pump control, and a 12 VDC fuse panel for unswitched battery power are mounted on the gray panel. The rear solar monitor panel, EMS display, inverter remote ON/OFF panel, and DirecTV control unit are shown on the right side of the photo.
View into hutch from the side-facing door opening. The solar monitor panel, EMS display, inverter remote ON/OFF panel, and DirecTV control unit are shown. The door was removed to provide easy access.
The solar control/monitor panel provides advanced battery monitoring, including battery state-of-charge condition in amp-hours from full charge and percentage of charge.
Convenience Center panel as installed by Grand Design. Modifications include the addition of a battery master switch that controls a remotely mounted battery disconnect relay, which replaces the mechanical battery disconnect originally mounted in the pass-thru. The water pump switch was replaced with a momentary push-push switch with 3-point control (Convenience Center, Bathroom, and Pass-Thru), and some behind the panel wiring changes to provide better system isolation.
Another view into hutch from the top, right, front-facing door opening showing Winegard DirecTV Traveler SAT antenna control unit, power supply, and insertion unit. A relay and terminal strip was added to facilitate the 3-point control for the water pump, and a four position fuse holder supplies unswitched 12 VDC power to several systems (refrigerator, entry light, & battery relay).
This view shows how the top-right section of upper hutch was sacrificed for the electrical modifications. A clear view of the floor to ceiling/roof OEM wire chase is also visible. This is the path that was used to route the solar wiring from the roof to the front Pass-Thru solar controller.
View of the back side of the equipment panel mounted above the Convenience Center. Top to bottom are the: Solar/Battery monitor, inverter remove ON/OFF switch, EMS display (front mounted), and the Winegard Traveler DirecTV control unit. Also visible is the added 12 VDC unswitched fuse panel. The refrigerator was connected to the "hot" battery bus to allow running the refrigerator for pre-trip cool-down while in storage with the rest of the power shut down.
In order to install the roof mounted solar and SAT antenna wiring, I needed to open a chase from the floor to the roof. The OEM ceiling wiring was routed behind the hutch, but was mostly covered over. I sacrificed the top right bay and boxed it in for wiring access, and also to house some of the SAT antenna, solar, inverter, and EMS components. Looking at the convenience center panel, there is an additional (for the 297TSTS) rocker switch labeled BATT OFF. I replaced the mechanical battery disconnect switch in the pass-thru with a remote operated relay that I control from this switch. This switch and relay are shown on sheet 1 of the Mod Wiring diagram. Click on the individual pictures below for an enlarged view or scan through the gallery.
