MPPT CHARGERS
FEATURES
Up to 30% more energy conversion efficiency as compared to ON/OFF and PWM type.
Reduction in wire thickness and hence cabling cost.
Battery Overcharge Protection.
Reverse Polarity Protection : Battery, PV and Load.
Load Protection : Overload, Short Circuit
Prevents Reverse battery current into PV panel at night.
Multiple layers of conformal coating for environmental protection.
Compact size compared to other MPPT chargers.
LED indicators and Remote Alarm annunciators provision.
TYPES
Indications:
Bicolour LED – Red – charging , Green – charged
Lo Batt – low battery (if battery voltage less than 10.8V)
O/L – Over load (20A)
Working :-
If PV voltage is more than Battery voltage then S1 will be ON and it will remains ON until Battery voltage reaches up to 14.4V, after 14.4V S1 will be OFF.
S2 will be OFF for two conditions as follows:
If Battery Voltage becomes less than 10.8V then S2 will be OFF and Lo batt LED will glow.
If load current more than 20A(+10%) then S2 will be OFF and OL LED will glow.
Above both conditions are latching type – to reconnect Load to the battery please press the RESET button.
