Technical details about the energy management

The charge controller aims to maintain the supply voltage at a constant of 3,8 V , as long as sufficient energy is provided by the PV module. If the PV module is unable to generate energy (e.g. at night or during storage), the Lizzox Pure Flood operates normally down to 3,4 V . The modem is deactivated from this threshold and the "UV MODEM LOCKOUT" log entry is entered in the device log. This means that the connection is disconnected if the device is in "online" mode or is logged in to the mobile network. Once this threshold has been reached, a connection establishment cannot be triggered manually via the solenoid switch (see Solenoid switch) nor automatically via the system. The remaining functions are not affected by this.

Only once the internal supply voltage falls below 2,9 V the Lizzox Pure Flood switches to the energy saving mode in which only the charge control is active. In this case, the charge control tries to charge the rechargeable battery to 3,8 V . The "UV LOCKOUT" log entry is also entered in the device log when activating energy saving mode. If sufficient energy is generated again by the PV module (e.g. dawn or positioning the device in the sunlight), the rechargeable buffer battery can be recharged again. Otherwise, the Lizzox Pure Flood will remain in this power-saving mode until the rechargeable battery is deeply discharged.

Energy saving mode is terminated and all of the functions except for the communication with the myDatanet server are resumed once the rechargeable battery voltage exceeds 3,2 V when recharging. The modem continues to remain inactive until the rechargeable battery voltage exceeds 3,5 V . Only then can a mobile network connection be established again and the device resumes normal operation.
