AC or Battery Priority
 
Our inverter is designed AC priority by default. This means, when AC input is present, the battery will be charged first.
When you choose battery priority(Battery type selector on 7-9), then inverter will invert from battery despite the AC input. Only when the battery voltage reaches low voltage alarm point will be inverter transfer to AC input, charge battery and switch back to battery when the battery is fully charged. This function is mainly for wind/’solar systems using utility power as back up.
 
Key features: 
 
To inverter:
 
►High overload ability up to 300% rated power (20 sec)
►Low voltage trip selectable (9.5V/10V or 10V/10.5V) extracting max power from various batteries with different protection
►Low quiescent current, power saver mode to reduce power consumption to 10W (3 sec sensing cycle)/3W (30s sensing cycle)
►DC13V battery recover point, dedicated for solar systems
 
To solar charger:
 
►MPPT function with high efficiency 97%
►Auto input DC voltage detect between 12V/24V
►Reverse current protection, battery temperature compensation
 
To battery charger:
 
►3 step intelligent battery charging (bulk, absorption, and float)
►8 pre set battery type (flooded lead acid, gel, or absorbed glass mat (AGM) batteries) selector
plus de-sulphation for totally flat batteries
►Powerful charge rate up to 90A, selectable from 0-100%
►PFC (Power Factor Correction) for charger, less power consumption than conventional units
 
To transfer:
 
►10ms typical transfer time between battery and AC, guarantees power continuity
►15s delay before transfer when AC resumes, extra protection for loads when used with generator
►Input AC voltage range selectable (184-253V or 154-253V) for different kinds of loads
►30/40A through current ability
►Allows start up and through power with depleted batteries
 
To remote control & others:
 
►Ability to switch the unit on/off, select/deselect power saver mode
►17 alarms/warnings, informative for easier operation and trouble-shooting
►Front panel LED indicators and adjustable switch selectors
►Battery/AC priority switch available for off grid solar/wind system
►Low battery, overload, and high battery, over temperature protection circuitry
►RS232/USB communication port available
►Generator compatible
