Why a battery should be monitored
Operating your battery bank without good metering is like running your car without any gauges,
although possible to do, it's always better to know how much fuel is left in the tank.
Defining the amount of energy available in a battery is a complex task, since battery age, discharge
current and temperature all influence the actual battery capacity. The Expert Modular is equipped
with high performance measuring circuits and complex software algorithms, to exactly determine
the remaining battery capacity.
Besides offering an accurate state of charge indication, the Expert Modular will also help users how
to get the best service life out of the battery bank. The service life of batteries will be negatively
affected by excessive deep discharging, under- or overcharging, excessive charge- or discharge
currents and/or high temperatures. The user can detect such abuse easily through the clear display
