------------------------------------
Isolated sensing of Mains: This will ensure that even if Phase-Neutral connection is reversed at the input side there will not be any electric shock on the PCB or battery.
Cycle-Cycle current Limiting: This is a enhanced protection method for the short circuit / heavy load condition.
Low cost driver: The costly driver with TLP250 is replaced with discrete components on the PCB
LED/7-segment/LCD display: The PCB is designed with provision for LED, 7-segment display or LCD display.
This inverter is a very robust design which will not fail in any extreme conditions.
If 440V is applied to the AC input, it will not fail. It will indicate high voltage cut-off and restart when voltage is normal.
If AC mains is given to the inverter output, it will not fail. It will indicate phase input output reverse and continue to work after it is rectified.
It has fold-back current limiting for short circuit and heavy loads. At short circuit or heavy loads, current limiting action will take place instead of tripping which will lead to more reliability.
Features
LCD display for indicating various status of the system like inverter voltage, mains voltage, battery voltage, % of load, overload/short circuit status, battery low status, charger status etc.
LCD based Menu driven setup of various parameters like battery full charge voltage, battery low voltage, load condition, Inverter output voltage, charging current etc.
Protections against: Overload, short circuit, battery deep discharge, battery over charge, mains over voltage, reverse connection of phase in – phase out, reverse connection of phase and neutral of mains input. In all these error conditions will be shown in the LCD display.
Priority solar charging facility: When solar charger is connected mains charger will be in stand-by and priority will be for solar charger.
Delayed inverter cutoff for conditions like battery low, overload, short circuit etc. The system will automatically restart from cutoff after a few second buzzer beeps. The system will go to permenant cutoff if the error condition exists even after 4 restart.
