Victron Skylla-i 24/80/2 Battery charger 24V 80A two outputs 80A + 4A battery bank 400/800Ah

Victron Energy Skylla-i Series Battery Charger 24V 80A 2 Outputs.

SKYLLA-I battery chargers - microprocessor control.
Synchronised parallel operation.
Several chargers can be synchronised with the CAN bus interface. This is achieved by simply interconnecting the chargers with RJ45 UTP cables. Please see the manual for details.

The right amount of charge for a lead-acid battery: variable absorption time
When only shallow discharges occur the absorption time is kept short 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 BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the Skylla-i 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 in use: the Storage mode
The storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the storage mode float voltage is reduced to 2,2 V/cell (26,4 V for 24 V battery) to minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘refresh’ the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failure.

To increase battery life: temperature compensation
Every Skylla-i comes with a battery temperature sensor. When connected, charge voltage will automatically decrease with increasing battery temperature. This feature is especially recommended for sealed lead-acid batteries and/or when important fluctuations of battery temperature are expected.

Battery voltage sense
In order to compensate for voltage loss due to cable resistance, the Skylla-i is provided with a voltage sense facility so that the battery always receives the correct charge voltage.

• Power supply range : 180-265 VAC and 180-350 Vdc
• This particular version has all the features of excellence present in the Skylla family and it adds other interesting features such as The Predisposition to charge Li-Ion (LiFePO4) and the Synchronised parallel operation via CANbus interface
• The Skylla-I chargers, as the other Skylla units, are suitable for AC and DC (AC-DC and DC-DC operation), and as a power source due to the perfect stabilization of the output voltage
