SES COMPLETE 48 VOLT BATTERY BANK SYSTEMS WITH ENCLOSURES AND CABLING-39 kWhr

SES Project Highlight-Critical power for US Department of Defense
Solar Electric Supply designed and supplied this 30 kW Sunny Island system to the US Army on the remote Bikini Atoll Islands in 2011. It provides critical power for satellite communications, a school, and base power. The AC coupled system uses a four Sunny Boy 5000US inverters and PV arrays distributed on the base that feed the six Sunny Island inverters for 30 kW 208 VAC three phase power. Dual 30 kW diesel gensets are controlled by the Sunny Islands and Multicluster for backup and load sharing. A parallel Deka sealed AGM battery bank rated at 130 kWhr @ 48 VDC provides backup power at night and during cloudy weather.
