Displays the actual produced solar module‘s 

current output.

Displays the charging current flowing into 

battery from the solar module.

Displays the current drawn by the load 

output.

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 rea-

ched, it will switch back to 0 Ah.

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.

As an early warning, the SOC bar or the 

voltage value flashes. The face still looks 

friendly! 

If the deep discharging protection has been 

activated the SOC bar or the voltage value 

flashes. The face looks sad until the reconnec-

tion setpoint is reached.

This charging regulator has basic functions for specifying the charging state 

(SOC), charging specification and deep discharge protection that are descri-

bed 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.

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. Mo-

difications in the system, e.g. the battery’s aging process are automatically 

taken into consideration by the system’s continuous learning process.
