VICTRON - Smart Solar MPPT 75/15

Built-in Bluetooth Smart: No dongle needed
The wireless solution for set-up, monitoring and updating of the controller using Apple and Android smart phones, tablets or other devices.

VE.Direct
For a wired data connection with a Color Control Panel, a PC or other devices.

Ultra fast Maximum Power Point Tracking (MPPT)
Especially in overcast sky, when the light intensity is constantly changing, improves an extremely fast MPPTRegler the energy yield compared to PWM charge controllers by up to 30% and in comparison to slower MPPT controllers by up to 10%.

load output
Overcharging of the battery can be prevented by all loads are connected to the load output.
The load output disconnects the loads when the battery has been up to a predetermined voltage value discharged.
Alternatively, can also choose an algorithm for intelligent battery management: See Battery Life.
The load output is short-circuit proof.

Battery Life: intelligent battery management
If the solar charging controller is not able to charge the battery within one day up to its full capacity, the status of the battery changes constantly "partially loaded" and between "the end of discharge" back and forth.
This mode of operation (no regular full charging) damaged a lead-acid battery within a few weeks or months.
The Battery Life algorithm monitors the state of charge of the battery and, if necessary he lifts every day the threshold value for separating the load on (i. E., The load is disconnected earlier) until the recovered energy sufficient to charge the battery up to almost 100%. From this point, the threshold value is modulated for the disconnection of the load, so that the charging nearly 100% is achieved about once weekly.

1a) If more PV power is connected, the controller limits the input power
1b) The PV voltage must reach at least the height of Vbat + 5 V, so that the controller receives the operation.
After that, the minimum value of the PV voltage at Vbat + 1 V. is
2) A higher short-circuit current can damage the regulator in the event of a reverse polarity connection of the PV system.
