Solar charge controller MPPT2215 BN
Module power up to 240 W at 12 V and up to 480 W at 24 V
Module open-circuit voltage up to 150 V
Battery voltage 12-24 V
Ideal to use the full power of your solar modules to charge a 12 or 24 V battery.
MPPT (Max Power Point Tracking) allows the optimal use of the complete power of your modules.
For most commonly used module technologies and module with optimal module voltages higher than the battery voltage.
You can also use modules that are usually used in grid-connected PV installations.
The Maximum Power Point of solar modules changes depending on multiple factors, e.g. module temperature, irradiation, type of module etc. This point of operation is constantly monitored by the internal microcontroller and adapted if necessary to get the maximum power of every module to charge the batteries.
This can be visualized with an example (130W module).
MPPT voltage = 17.5 V, MPPT current = 7.42 A, resulting in 17.5 V x 7.42 A = 130 W.
If the module is connected to the MPPT charge controller, the voltage is constant at 17.5 V.
However, if the module is connected to a normal controller with a 12 V battery, the module voltage is 12 V accordingly.
At full irradiation the module would deliver 12 V and 7.42 A, resulting in 12 V x 7.42 A = 89 W.
The advantage: the MPPT charge controller increases the output of your modules by up to 40 % compared to a regular charge controller.

In PV systems, lead-acid, lead-gel and lead-fleece batteries are used most commonly for storing energy. Lead-batteries need protection from discharging and overcharging. The MPPT solar charge controller meets both requirements and additionally maintains the batteries automatically through an intelligent maintenance function.
The switching thresholds for over- and under-voltage, load disconnection and reset voltage are controlled precisely and temperature-independent by the internal microcontroller. These switching thresholds are user selectable and freely programmable via PC-software.
With the Display MT50 or an adapter cable in combination with the integrated software, the charge controller can be controlled and monitored. Additionally, monitoring of the controller is possible via the PC-software.
4 battery types are selectable. In the battery type User, voltages are selectable and programmable via software (e.g. for lithium batteries)
A switchable load port allows the user to switch on and off every load connected to the solar controller with a simple press on a button or via the PC-software.
2 timers can control a night-light as soon as the regulator recognizes "night" through the solar module.
Yield data and system parameters can be recorded with the PC-software.
The optional Display MT50 offers monitoring and control options as well.
