3 | Battery Size Setting | Allows to enter the battery size (in Ah) Warning: make sure to check with the battery manufacturer that the selected settings are adequate. |
4 | Voltages setting | Press key 1 to access Float voltage. Press CHECK to accept. Press one of the following keys to choose the voltage: 1: 13.0V, 2: 13.4V, 3: 13.7V, 4: 13.9V, 0: 13.75V (default). Press key 2 to access Absorption voltage. Press CHECK to accept. Press one of the following keys to choose the voltage: 1: 13.8V, 2: 14.0V, 3: 14.25V, 4: 14.5V, 5: 14.75V, 6: 15.0V, 0: 14.4V (default) Press key 3 to access Low battery disconnect. Press CHECK to accept. Press one of the following keys to choose the voltage: 1: 10.0V, 2: 11.5V, 3: 12.0V, 0: 11.25 (default) The DC outputs of the SHS are switched off when the low voltage disconnect is reached to prevent deep discharge of the battery. |

8 | Battery Internal Resistance | To define the internal resistance of the battery (default 15mOhm) |
9 | Battery Maximum Depth of Discharge | Default is 50%. This parameter defines the usable capacity of the battery as a percentage of the total capacity of the battery. The recommended setting for lead-acid batteries is 50%. At this setting, only 50% of the battery capacity will be usable, but this limit should allow a drastic increase in the life of the battery (typically 3 times the duration compared to 100% DoD). |
In the Special menu* there are different Sub-Menus that are accessible by pressing the corresponding key:
1 | USB ports protection | to enable/disable the overcurrent protection on USB ports. |
2 | DC12 ports protection | to enable/disable the overcurrent protection on DC12 ports 1: enable the protection; 2: disable the protection |
