MPPT controller upgrade option for 100w and 150w foldable solar panel kits.
• 12V and 24V battery compatible. • Max input voltage 75V. • Max charge current 15A • Ultra-fast Maximum Power Point Tracking (MPPT) • Advanced Maximum Power Point Detection in case of partial shading conditions • Load output on the small models • Battery Life: intelligent battery management by load shedding • Automatic battery voltage recognition • Flexible charge algorithm
Over-temperature protection and power de-rating when temperature is high. When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.
