Description
The blue solar Mppt 75 10 charge controller is designed for use with solar panels that produce a variety of voltages. It features an auto-selecting battery voltage of 12/24V, a rated charge current of 10A, and a maximum PV open circuit voltage of 75V. It also has a charge voltage absorption of 14.4V / 28.8V, which allows for a wide range of panel voltages to be used. The controller also features a 98% efficiency rating, self-consumption of 12V at 20mA and 24V at 10mA, and a temperature range of -30 to +60C.
FEATURES
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.
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.
