Description:
This is a maximum power point tracking (MPPT) solar charger for
single-cell LiPo batteries. This MPPT solar charger provide you with the
ability to get the most possible power out of your solar panel or other
photovoltaic device and into a rechargable LiPo battery. Set-up is easy
as well, just plug your solar panel into one side of the solar charger
and your battery into the other and you are good to start charging!
Solar maximum power point tracking (MPPT) is to ensure that the
light intensity change, photovoltaic cells output maximum power, to make
full use of solar energy. In general, need to use a switch mode DC - DC
converter to realize MPPT function, keep the output voltage and
charging current product maximize (output).
The output of the Solar Charger is intended to charge a single
polymer lithium ion cell. The load should be connected in parallel with
the battery. Each Solar Charger comes equipped with a CN3791 power
tracking battery charging circuit and pre-installed four 2-pin JST/PH2.0
connectors.
Default we have set the holding voltage for MPPT. So we have 3
version for the input voltage 6V/9V/12V(for Solar Panel working voltage
6V/9V/12V), very suitable for the application of the input voltage and
battery voltage difference is bigger.
Note: If the CN3791 MPPT Solar Charger is 9V version, you must use the Solar panel working Voltage is 9V.
Feature:
Input voltage: select the corresponding module according to the nominal voltage of the solar panel (6V/9V/12V)
