Victron Energy manufactures electric power conversion products for mobile and other off-grid applications since 1975
Victron’s BlueSolar range of reegulators feature ultra-fast maxium power point tracking (MPPT), advanced MPPT detection in case of partial shading, intelligent battery mangement by load shedding, automatic battery voltage recognition, flexible charge algorithm, over-temperature protection and power de-rating when temperature is high.
In our MPPT model names, for example MPPT 75/15, the first number is the maximum PV open circuit voltage. The second number, 15, is the maximum charge current.
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.
