Notes on the battery
•
If used improperly, batteries are a high risk for humans, animals and the environment.
Always observe
the safety instructions of the battery manufacturer!
•
Batteries contain aggressive corrosive acids. Avoid eye and skin contact with liquids from the battery!
Never disassemble batteries! If eyes or skin come in contact with acid, immediately rinse with running,
clear and cool water! Then seek medical help immediately! If acid gets on your clothes, remove the
contaminated clothes immediately and rinse any affected parts of the skin thoroughly with running, cool
water.

Description of functions
The MPPT
plus
+
solar controllers are modern, microprocessor-controlled devices which were developed for charging batteries in
solar stand-alone systems. The MPPT (maximum power point tracker) enables you to make optimum usage of the solar power
of your solar modules. The most efficient operating point of the solar modules changes due to factors such as exposure rate,
temperature and the type of solar cells. This optimum operating point (MPP - maximum power point) is monitored constantly by
the internal microprocessor of the solar controller and is controlled by the MPPT in such a way that your battery is always
charged with maximum power. When the maximum charge voltage of your battery has been reached, the MPPT
plus
+
solar
controller switches the charging current off. The microprocessor is also responsible for controlling all important protective
functions, such as the deep discharge protection. Its function is to switch off the load output automatically if the battery voltage
falls to 10.5 V. As soon as the battery is recharged by the solar module, the load switches back on automatically.
The load output can be activated manually using a push-button, and offers the option to switch on and off all consumers
connected to the MPPT
plus
+
solar controller by the push of a button.
With the aid of peripheral devices
(webbox and touchscreen remote control
), you can also control, parameterize and monitor the
device and other connected components.
