Victron BlueSolar MPPT 100/15

Ultra-fast Maximum Power Point Tracking (MPPT)

Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Load output

Ideal for small systems using DC as well as AC. Over-discharge of the battery can be prevented by connecting DC loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. Load output is short circuit proof.

Some loads (especially inverters) are best be connected directly to the battery, and the inverter remote control connected to the load output. A special interface cable may be needed, please see the manual

Improving Battery Life with Lead Acid battery management

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 achieve 100% recharge at least once every week. Not applicable to Lithium battery systems which can handle ‘partially charged’ with no problem.
