The power consumption of the complete MAWS system depends on
the connected sensors, communication devices, and other options
included in the delivery. For example, MAWS with basic set of 5
sensors, each having 10-minute measuring interval has an average
power consumption of 10 mA.
Internal Battery
Normally, the internal battery QMB101 (1.2 Ah) is used as the
primary power supply. The battery is recharged by the integral charger
in the logger, accepting input from a solar panel, mains adapter, or an
outdoors mains power supply. The QMB101 battery is placed on top
of the circuit board, under the logger cover, see Figure 4 on page 24.
Information about charging the battery can be found on page 169.
Solar Panels
SOLAR6 with MAWS201
MAWS201 is typically powered by SOLAR6, a 6 W solar panel, see
Figure 7 below. The angle of the panel is adjustable.

Figure 7 SOLAR6 Solar Panel
The SOLAR6 solar panel contains 18 high efficiency polycrystalline
silicon cells in series optimized for the specific voltage demand. The
solar panel’s cells are protected from dirt, moisture and impact by a
tough fluoropolymer front film. The solar circuit is laminated using
EVA between this film and adurable glass fibre board back which
includes integral mounting holes.
