4.2.3. Module current
Displays the actual produced solar module‘s current output.
4.2.4. Charging current
Displays the charging current flowing into battery from the solar module.
4.2.5. Load current
Displays the current drawn by the load output.
4.2.6. Ah – Battery charging meter
Displays the accumulative sum of recharged
Ah since the initial installation or reset. Press both buttons for 3 seconds to reset the meter to 0. Ever when the battery is disconnected the value remains. When 99.9 KAh are reached, it will switch back to 0 Ah.
4.2.7. Ah – Battery discharging meter
Displays the accumulative sum of Ah drawn by load since the initial installation or reset.
Press both buttons for 3 seconds to reset the meter to 0. When 99.9 KAh are reached, it will switch back to 0 Ah.
4.2.8. Warning deep discharge protection
As an early warning, the SOC bar or the voltage value flashes. The face still looks friendly!
4.2.9. Load disconnection
If the deep discharging protection has been activated the SOC bar or the voltage value flashes. The face looks sad until the reconnection setpoint is reached.

5. Function Overview
This charging regulator has basic functions for specifying the charging state
(SOC), charging specification and deep discharge protection that are described in the following section. Additional functions that can be activated such as the settings, night light function, auto-test, presetting and serial number query are explained under the corresponding menu items in chapter 6.
5.1. SOC Calculation
During operation, the regulator monitors various parameters (U; I) of the battery and from that calculates the battery’s charge level (SOC = state of charge). The charge level is the energy level still available in the battery. Modifications in the system, e.g. the battery’s aging process are automatically taken into consideration by the system’s continuous learning process.
