Programmable battery charging algorithm

Battery life: intelligent battery management

Ultra-fast maximum power point tracking (MPPT)

Especially in cloudy skies, when light intensity is constantly changing, a very fast MPPT controller improves energy yield by up to 30% compared to PWM charge controllers and even 10% compared to slower MPPT controllers.
Smartphone or other Bluetooth device: This requires the VE.Direct Bluetooth Smart Dongle.
The charge controller collects the energy from the solar panels and stores the energy in the batteries.
Utilizing the latest and fastest charging technology, BlueSolar maximizes energy harvesting, intelligently controlling energy harvesting to achieve maximum charging in the fastest possible time.
SmartSolar maintains batteries and extends their lifespan.

Battery life: intelligent battery management
If the solar charge controller is unable to charge the battery to its full capacity within 24 hours, the battery status will constantly cycle back and forth between "partially charged" and "end of discharge".
This method of operation (no regular full charge) will damage the lead acid battery within a few weeks or months.
The Battery Life algorithm monitors the battery's charge status and, if necessary, raises the load cutoff limit day by day (i.e., the load is cut off earlier) until the energy received is enough to charge the battery almost 100%.
From now on, the power-off threshold is modulated so that nearly 100% charge is reached approximately once a week.
