Victron Energy BlueSolar MPPT 75V 10A Charge Controller
Victron Energy BlueSolar MPPT 75V 10A Charge Controller – this is an independent review for Victron Energy BlueSolar MPPT 75V 10A Charge Controller we have compiled for your reference. Feel free to add your comments or experiences at the bottom of the page.
An MPPT regulator from the BlueSolar range, manufactued by Dutch company Victron Energy - one of the market leaders in solar power electronics equipment. charge controller is capable of providing significantly more power to a battery bank from the solar array, compared to conventional PWM charge controllers, in addition to maximising the battery lifespan. The MPPT regulator is effectively a dynamic DC-DC converter which constantly adjusts and optimises the voltage output from the solar array, which can vary considerably, in order to provide a constant charging voltage for the batteries - which improves their lifespan and equates to lower power losses in the sytem.

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.
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. A special interface cable may be needed, please see the manual.
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.
