Victron BlueSolar MPPT Solar Charge Controller

Ultra Fast Maximum Power Point Tracking (MPPT)
Especially under cloudy skies, when light intensity is constantly changing, an extremely fast MPPT controller improves the energy yield by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers

Load output
A too deep discharge of the battery can be prevented by connecting all loads to the load output. The load output disconnects the loads when the battery has been discharged to a specified voltage value. Alternatively, an algorithm for intelligent battery management can be selected: see Battery Life. The load output is short circuit proof. Some loads (especially inverters) are best connected directly to the battery. The inverter remote control is best connected to the load output. A special interface cable may be required, please refer to the manual

Battery Life: intelligent battery management
If the solar charge controller is not able to charge the battery to its full capacity within one day, the status of the battery constantly changes between "partially charged" and "end of discharge". This operating mode (no regular full charging) will damage a lead-acid battery within a few weeks or months. The Battery Life Algorithm monitors the battery's state of charge and, if necessary, it raises the load disconnect threshold (i.e. load is disconnected earlier) on a daily basis until the energy gained is sufficient to charge the battery to near 100%. At this point, the threshold for disconnecting the load is modulated so that near 100% charging is achieved approximately once a week
