Western WMarine10 Manuel De L'utilisateur page 13

WMarine10 has got a buck-boost charge circuit with control of the maximum
power point of the PV module (MPPT). The main difference between this
controller and other types with buck circuit (as for instance WRM20) is that
WMarine10 is able to allow the working of the PV module at a voltage than can
be either higher or lower than that of battery; this allows, for example, to use a
PV module with open circuit voltage of 10V for the charge of batteries both at
12V and 24V. PV module voltage during the working of MPPT circuit goes from
5V to 40V with both 12V and 24V batteries.
WMarine10 is a complete solution for the realization of off-grid PV systems, to
power supply road signs systems, lighting systems, small low voltage systems
and for the charge
The several programs of load management, selectable by the user, make
WMarine10 the proper solution in several applications; i.e. to power supply
video cameras that have to work only during the day, or to power supply
flashing systems/road signs that have to work only during night or to power
supply lighting systems that have to work only for a certain number of hours
during night. WMarine10 detects the day/night status according to the PV
module's voltage; therefore, it is not necessary to connect further sensors to
the controller. A wide display shows the working status of the charge
controller either through simple and intuitive icons or displaying the values of
charge current, battery voltage, energy produced by the PV module, load
current and energy consumed by the load.
