LCD display MPPT solar charge controller

Untra-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 outputwill 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 remotecontrol 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 slightlyincrease the load disconnect level (i. e. disconnect the load earlier

until the harvested solar energy issufficient to recharge the battery to nearly the ful

99%. From that point onwards the load

disconnect level will be modulated so that a nearly 99% recharge is achieved about once every week

Maximum Power Point Tracking

Upper curve

Output current o of a solar panel as function of output voltage（V）

■The maximum power point(MPP)is the point

Pmax along the curve where the product x V reaches its peak

Lower curve:

■Output power P=l as function of output voltage.

When using a PWM(not MPPT) controller the output voltage of the solar panel will be

nearly equal to the voltage of the battery, and will belower than Vmp.

1a) If more PV power is connected,the controller will limit input power to the stated maximum.

1b) PV voltage must exceed  Vbat +5V for the controller to start. Thereafter minimum PV voltage is Vbat +1V.
