Applications; Identification - Grundfos AQtap Installation And Operating Instructions Manual

7.1.1 Power supply
The AQtap can to be operated with grid and / or solar power. It
uses the power supply in the following hierarchy:
1. solar power,
2. grid power,
3. battery.
Using solar power requires a connected battery. The internal
battery is loaded when grid or solar power is available, and is
used as a backup power for approximately 12 hours of operation.
After discharging the backup battery, tapping water will not be
possible right away when power (solar radiation) is on again, until
the battery is recharged. If the internal battery is not powerful
enough, it can be substituted by an external battery.
Depending on the solar radiation and degree of
AQtap utilization the internal battery and
charging with solar power can be insufficient.
Note
In cases where tapping is not possible after using
the backup battery, an external battery with MPPT
solar charger can be used.
See section Power supply requirements.
7.1.2 Water supply
The water supply must provide clean drinking water. See section
