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 "BTY VOLT" on AC side?

What is the "BTY VOLT" on AC side?

Q: What the volt adjustment is for on the battery charger it the small white round switch with #o to 9 so please what dose it do?
A: On the volt adjustment, you can adjust this to match your battery voltage, "1" is the lowest battery voltage, and "8" is the highest battery voltage,(0 and 9 do not have charging function), you can begin from 1, then 2, then 3..., until the right number that suit for your battery voltage.

Which AC INPUT for battery charger do I choose on 240V inverter?

Which AC INPUT for battery charger do I choose on 240V inverter?

220V-240V AC INPUT for battery charger:
When total on load power <1500w (0-5A), please use AC input socket for charging .
When total on load power >1500w and <3000w(0-10A)(with a 3000w-inverter), please use AC input H line bank for charging.

How many amps of the battery do I need for this 3000w power inverter ?

How many amps of the battery do I need for this 3000w power inverter ?

If the inverter is 3000w power inverter with dc 12v, 90% efficiency, then the battery you need is:  3000w /12v / 90% inverter efficiency / 80% battery efficiency

What is the size of battery cable do I need with your power inverter?

What is the size of battery cable do I need with your power inverter?

inverter watts / 87% efficiency = primary power
primary power / volts = primary current
primary current / 10 = (         ) mm2 cable
