BlueSolar MPPT 70/15

Ultra-fast Maximum Power Point Tracking (MPPT)

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.

Order Code: BlueSol MPPT75/15

Description

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

Features

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

Over-discharge of the battery can be prevented by connecting all 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.
The load output is short circuit proof.
Some loads (especially inverters) can best be connected directly to the battery, and the inverter remote
control connected to the load output.

Battery Life: intelligent 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 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.
