GTSUN 3000W Peak 9000W Pure Sine Wave Power Inverter With Battery Charger, MPPT 60A Solar Charger Controller Regulator ,DC 24V AC Output 110V, Utility/Transfer SW / Inverter /Charger /Solar Power /AGS *SP-PV Series Pure Sine Wave Inverter is a combination of an inverter, AC charger, Mppt solar charger and Auto-transfer switch into one complete system.It is packed with unique features and it is one of the most advanced inverter/chargers in the market today *Our inverter is designed with AC priority by default. This means, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load.The AC Priority and Battery Priority switch is SW4.When you choose battery priority, the inverter will inverting from battery despite the AC input *SP-PV Series Inverter is equipped with a powerful charger of up to 120Amp (depending on Model).The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools and equipment longer. the max chargecurrent can be adjusted from 0%-100% via a liner switch at the right of the battery type selector.This will be helpful if you are using our powerful charger on a small capacity battery bank *Frequency adjust: The frequency of the inverter is arranged by the SW4.The default configuration for 60Hz for 100/110/120VAC inverter.While the output freq can be easily changed once a qualified freq is applied to the inverter Protections:AC Input over voltage protection/AC Input low voltage protection,Low battery alarm/High battery alarm,Over temperature protection/Over load protection,Short Circuit protection (1sec after fault),Back feeding protection *Applicantion:for all the kinds of load:circular saws,drills,grinders,sanders,buffers,weed and hedge trimmers, air compressors.computers,printers,monitors,facsimile machines, scanners.vacuum cleaners, fans, fluorescent and incandescent lights,shavers, sewing machines.coffee makers, blenders,ice markers, toasters.metal halide lamp, high pressure sodium lamp.television, VCRs,video games, stereos,musical instruments, satellite equipment ect
