when main power is off,it auto switches on and have AC output, when main power work,auto switches to charge the battery.
Features & details
When you run a AC appliance with battery being hooked with Xincol XCU Auto-switch DC/AC power inverter/charger which also connects your wall outlet or AC mains power socket, during normal operation, the inverter/charger just passes the electricity coming from your mains power outlet through to the operating appliance though the appliance was plugged directly into the outlet. While it is doing that, it will also automatically charge the batteries and keep them fully charged as long as it continues to receive power from the AC mains power outlet.
When your power goes out, the system will automatically send power from the batteries to the operating appliances.
Inverter/chargers vs. UPS systems
This description of an inverter/charger sounds an awful lot like the description of an uninterruptible power supply (UPS), which might lead you to wonder, “Why can’t I just install a UPS and be done with it?” Well, it basically boils down to the fact that a UPS is just not designed to do the job.
Although inverter/chargers and UPS systems work in very similar ways and perform similar functions, the battery in a UPS is not large enough to run your appliances for any significant length of time. Most UPS systems are not designed to provide enough power to start a big wattage AC appliances like a sump pump. In addition, UPS systems have very small battery chargers and they are heavy and expensive most of the time.
An inverter/charger also allows you much more flexibility to decide how much power you need. You can think of it like buying stereo equipment: you can buy the “all in one” model, which is inexpensive and easy to assemble but offers less powerful sound (the UPS), or you can buy individual modular components, which gives you increased flexibility and more powerful sound (the inverter/charger). And if your needs change in the future, you can expand the system without having to start over again.
