14 May 2019

For more information please see PSD Solar Power System Maintenance RFP 5-14-19. Bidders can review the system manual  and schematic for more information.

The power systems were designed for 200 watts average and continuous power, and 250 watts peak power.  They have solar panels (9 x 275 watt PV panels for 2475 peak watt) for continuous charging, with a battery of 8 modules (24 VDC) with a capacity of 1200 amp hours, to provide approximately 5 days of system autonomy.   Site 180-08 (Brighton/Island Pond) is a little different: it has 15 x 275 watt PV panels (4,125 peak watt array), the same battery, and a Cummins propane genset 5.5 HGJAE-2144 (5.5 kW, 23 Amp).  The systems are all net metered and provide both 110 VAC and 24 VDC output.
