Adaptive 4-stage charge characteristic: Bulk-Absorption-Float-Equalize
The “Stackable Inverter” features a microprocessor controlled “adaptive” battery
management system that can be preset to suit different types of batteries. The “adaptive”
feature will automatically optimize the process relative to the way the battery is being used.
The right amount of charge: Variable Absorption Time
When only shallow discharges occur (a yacht connected to shore power for example), the
absorption time is kept in order to prevent overcharging of the battery. After a deep
discharge, the absorption time is automatically increased to make sure that the battery is
completely recharged.
Preventing damage due to excessive gassing: The Battery Safe Mode
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen. The “Stackable Inverter” will prevent damage due to
excessive gassing by automatically limiting the rate of voltage increase once the gassing
voltage has been reached.
Less maintenance and aging when the battery is not use: The Equalize Mode
The equalize mode kicks in whenever the battery has not been subjected to discharge during
24 hours. In the equalize mode, float voltage is reduced to 2.2V/cell (13.2V for 12V battery)
to minimize gassing and corrosion of the positive plate. One a week, the voltage is raised
back to absorption level to “equalize” the battery. This feature prevents stratification of the
electrolyte and sulphation, a major cause of early battery failure.
2 outputs to charge 2 battery banks
The “Stackable Inverter” features 2 outputs, of which 1 can carry the full output current.
The second output, limited to approximately 4A and with a slightly lower output voltage, is
intended to top up a starter battery.
To increase battery life: Temperature Compensation
Every “Stackable Inverter” comes with a battery temperature sensor (BTS-3) when
connected, charge voltage will automatically decrease with increasing battery temperature.
This feature is especially recommended for sealed batteries and/or when important
fluctuation of battery temperature is expected.
