What is the UPS function on the LF inverter?

What is the UPS function on the LF inverter?

When use UPS function, the inverter should have battery connected on the DC input side, and the home grid connected on the AC input side, home grid has power, the led light marked " BTY ON" will be on, it will charge the battery. When the home grid power is off, the inverter function will be work, the led light marked "INV ON" will be on, the battery charger function will turn on automatically when the ac input is restored following an ac power failure.

How to charge my battery with your LF inverter with charger function?

How to charge my battery with your LF inverter with charger function?

To charge the battery, need to confirm the following situations:
1.right dc voltage, for dc12v inverter the voltage range is 10.5-15V, for dc 24v inverter, the voltage range is 21-30V, for dc 48v inverter, the voltage range is 42-60V.
2.AC INPUT must connect to the home grid, and the home voltage and frequency must be the same as the inverter's, also should be pure sine wave.

What is the switch "-"&"="mean?

What is the switch "-"&"="mean of your power inverter?

Q: What is the switch "-"&"="mean?
A: 1. the switch of above"=" is: power saved on. It will scan the load which is more than 25w within 4 seconds, then start; the current draw of power save on is 1/3 of power save off.
2. the switch of below"_" is: power saved off. When on load, it can be instantly started.

Why should you choose our power inverter?

Why should you choose our power inverter?

Why should you choose our power inverter?
1. Our PCB Board is manufactured by machines, not by hand !This is extraordinary clean and it gives no cable tangle !
2. Our Material is First Hand Material! We do not use "Second Hand Material" like many other supplier !
3. Important Delivery Parts are manufactured in USA, Japan and Germany, not in China !
4. The Power Output is very constant.When using Strong Machines the IC Program recognizes this and provides at the beginning a Higher Power which adapted later !
5. If you use our Power Inverter for a long time, you can see the difference to similar products of other suppliers !!!

How does the ATS function work on this 12v LF inverter?

How does the ATS function work on this 12v LF inverter?

ATS Function on 12v LF inverter:
a. when switch to ATS function, then:
for 12v system, your battery voltage when 10.5v, will auto switch to ATS mode, means inverter will auto switch the home power to provide the 220v AC output & charge your battery at the same time. After charge your battery to 14v,will be back to inverter mode. (PS.AC input cable need plug in all the time)
b.if you are using solar system, then you need stay at ATS function , because in the day time, all the power come from solar, after night time or battery under 10.5V,  will auto switch to home power, will let your electric products keep working, until day the sun come on again, then will be back to inverter mode again.

Can I plug my appliance to your AC output socket？

How long I can use if I want to run 1000w air conditioner?

How long I can use if I want to run 1000w air conditioner with your inverter?

Q: My air conditioner is 1000w, how long I can use it?
A: That's need see how big battery bank you have, watt=volt x amp,
1000w/12v=83amp, bank need 4-5 times to turn it on, means 83ax5=415amp
Otherwise, your battery bank will be very easy to low down the voltage when turn on the air conditioner , remember, this is not about inverter, it's about your battery bank has enough power or not.
