Specifications include, but are not limited to: 21’ x 6” SCH80 top-of-pole array with large load - 24VDC system Assume the following location near MP 69.2 on I-70 as the Proposed Site for the Design of Equipment for each scenario: Latitude: 38°54’20.18”N Longitude: 111°38’24.23”W Notes on Design of Equipment: Typical max load: ~50 watts PV panels: Compatible with top-of-pole mount. Where applicable, designs 5 days of autonomy for each setup below would be preferred. The RWIS Maintenance group utilizes LiFePO4 batteries for their lightweight design, no limitations on installation orientation, lifespan, depth of discharge, and battery management systems and would require that this type be provided. However, any solar controllers supplied will require customizable low-temperature foldback settings and battery temperature sensing. Optional LiFePO4 batteries with heating capabilities will be accepted if they can integrate into said solar controllers while continuously supplying power to the load. Other optional battery chemistries would also be considered. For all PV panel pole mounts described below, they must withstand wind gusts up to 105 mph and be able to tilt to at least 65 degrees. All battery enclosures shall be ground-mounted or pole-mounted (on poles varying from 4 to 10 inches in width) and be able to fit on the mentioned pole or service pad. They shall be insulated and ventilated and allow a padlock to be placed on them. All pole-mount enclosures must also be able to accommodate the solar controller and power distribution components. Optional non-photovoltaic systems or supplemental power systems to accommodate the various RWIS setups below would also be considered
