Battery Bank
Batteries are a critical part of your Off-Grid Energy System as they store energy produced
by the renewable energy and fuel powered generators to be used at times when these
aren’t available.
The batteries have been carefully sized to meet your requirements according to your Load Demand
assessment. Although sealed-gel batteries do not need fluid top up like wet-cell batteries, they do need
careful looking after to guarantee safe operation and a long service life.
o
Heavier demand leading to more frequent and deeper discharge/cycling than planned will shorten the
designed service life.
o
Not fully recharging the battery bank on a regular basis will shorten the designed service life.
o
An average storage temperature of between 20
°C -
25°C will help preserve battery service life. Lower
temperatures temporarily decrease available capacity but higher temperatures decrease battery life
expectancy and should be avoided. Temperatures above 40° C should be avoided as far as possible by
implementing good cross ventilation and shading etc.
WARNING
o
Keep batteries well ventilated with good cross-air flow
o
Keep battery enclosure locked at all times
