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 Note In battery priority mode when qualified AC inputs for the first time the inverter will only go into battery priority mode after a cycle of bulk charging and absorb charging is finished The inverter will not go into float charging mode 2 5 14 Output Socket The inverter is either equipped with a dual GFCI socket rated at 30Amps or an universal socket rated at 10Amps for more convenient wiring 2 5 15 Other Features Battery voltage recovery start After low battery voltage shut off 10V for 12V model or 20V for 24V model the inverter 1s able to restore operation after the battery voltage recovers to 13V 26V with power switch still in the On position This function helps to save the users extra labor to reactivate the inverter when the low battery voltage returns to an acceptable range in the renewable energy systems The built in battery charger will automatically reactivate as soon as city generator ac has been stable for 15 seconds WARNING Never leave the loads unattended some loads like a Heater may cause accident in such cases 21 AIMS Power www aimscorp net It is better to shut everything down after low voltage trip than to leave your load on due to the risk of fire Auto Gen Start The inverter can be customized to start up a generator w
6. It is suggested to gradually put the charging load on the generator by switching the charging switch from min to max Together with the 15s switch delay our inverter gives the generator enough time to spin up This will depend on the size of the generator and rate of charge 2 5 3 Transfer While in the Standby Mode the AC input is continually monitored Whenever AC power falls below the VAC Trip voltage 154 VAC default setting for 230VAC 90VAC for 120VAC the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances as long as the inverter is turned on The transfer from Standby mode to Inverter mode occurs in approximately 10 milliseconds And it is the same time from Inverter mode to Standby mode Though it is not designed as a computer UPS system this transfer time is usually fast enough to keep your equipment powered up There is a 15 second delay from the time the inverter senses that continuously qualified AC is present at the 11 AIMS Power www aimscorp net input terminals to when the transfer is made This delay is built in to provide time for a generator to spin up to a stable voltage and avoid relay chattering The inverter will not transfer to generator until it has locked onto the generator s output This delay is also designed to avoid frequent switching when input utility is unstable 2 5 4 Auto Frequency Adjust The inverter is designed with an Auto Frequency adjust function
