1. the MPPT solar controller has the function of simultaneous input of two solar panels. In theory, the two solar panels can input
different open circuit voltages and different power, and both can work normally. however, in order to balance the overcurrent
inside the controller, it is strongly recommended that the solar panels of the same specification be used in both ways, which is
beneficial to the service life and efficiency of the controller.
2.
The controller has a limited power function, and when the total power of the two solar panels or each input solar panel exceeds
the rated power, the controller will limit the charging power to the rated power, so it is strongly recommended not to connect to
solar panels that exceed the rated power.
■
Connect the wire
1.For the specification of the connecting cable, refer to the installation instructions.
2.When the connection cable between the solar panel or controller and the battery is relatively far away, the use of a thicker cable
can reduce the voltage drop and increase charging efficiency
■
Installation and connection
Warning: the danger of explosion!
Never install the controller and thebattery in the same airtight space! Nor should it be installed in an airtight battery where gas
may accumulate the place.
Warning: high pressure is dangerous!
PV arrays may generate high open-circuit voltages. Disconnect circuit breakers or safety before wiring, and be careful
during wiring.
Note
: when installing the controller, make sure that enough air flows through the heat sink of the controller, and there is at least
150mm space above and below the controller to ensure natural convection and heat dissipation.
If installed. In a closed box, it is necessary to ensure reliable heat dissipation through the box.
M4860ADS is a common positive design controller. The
electrode of solar panel and battery can be grounded at the
same time, or any positive terminal can be grounded. In practical application, the terminal can also be grounded.
It is not necessary to ground separately, but the shell must be grounded during installation, which can prevent external
electromagnetic interference and shell electrification from causing damage to the human body.

■
Temperature compensation
Note
: when the remote temperature sensor is not connected, the controller will charge or discharge the battery at 25
℃
by
default, without temperature compensation.
■
Modification of battery charging parameters
Note: when selecting the default battery type, the charging parameters cannot be modified. If you want to modify the charging
parameters, the battery type must select "Custom".
■
Overheat protection
When the internal temperature of the controller is more than 80
℃
, the controller stops working. When the temperature drops
to 60
℃
, the controller resumes charging. If the overtemperature protection is repeated three times, the charge will be stopped
completely. which needs to be reset manually or can be recharged the next day.
