How SARBS powers, houses and maintains equipment on telecom tower sites.
A gel battery uses silica gel and porous separators so an outdoor telecom site can cycle in heat and cold without a flooded cell.
A lithium battery is valuable enough to steal. The SARBS rack hides the locks and braces the door so the string stays in the compound.
An outdoor telecom cabinet is the room the tower never had: power, radio gear and a sealed climate, built to an ETSI 19 footprint.
A tower is on air only when the DC plant, the battery, the cabinet and the earth path are all finished. Here is the order SARBS sites actually follow.
Antennas get the photograph. The pad, the fence, the power trench and the acceptance test are what make a tower site real.
Where the feeder is weak or missing, SARBS solar sits with the battery and the rectifier so the tower is not waiting on diesel every evening.
