Fitted with multistage charging algorithm (bulk-absorption-float-recycle), the built-in charger of
Inverter Charger is designed to charge the battery quickly. Microprocessor controlled charging algorithm
with variable absorption charging timer will guarantee optimal charging for batteries of different
discharged state.

Float charging and recycle charging program guarantee your battery is getting proper maintenance
in case of long standby periods providing less aging.
Battery Sample Cable (Temperature and voltage)
Battery temperature is a key factor in correct charging for lead acid batteries. The charging formula must
be adjusted (automatically and in real time) according to the actual battery temperature to ensure that
the battery is fully charged but not overcharged or undercharged. All charging voltages recommended by
battery manufacture are in fact ONLY applied at 20°C-25°C and the temperature probe ensures optimal
charging..
The Bat sample cable (battery temperature and voltage sensor) supplied with Inverter Charger
measures the temperature of battery and automatically makes adjustments at real time to properly
charge your batteries at compensation rate of – 4mV/°C/cell. In case of Bat sample cable is not
present, Inverter Charger will use 25°C as default setting. This feature is especially recommended
for sealed batteries and/or when important fluctuations of battery temperature are expected.
Different battery chemistries
Inverter Charger offers premium charging algorithm for commonly encountered lead acid battery
chemicals include AGM, GEL, Wet, lead-carbon and Lithium battery, of which you can set
through the LCD/LED interface.
