Why there have 2 set red & black dc terminals?

Why there have 2 set red & black dc terminals of power inverter?

If you are using big watts appliance, this can separate to 2 set red & black(both 2 red are connected, 2 black are connected) to balance one cable have big amp coming for avoiding the cable to hot & efficiency)

What battery cable size should I use on this 8000w modified power inverter?

What battery cable size should I use on this 8000w modified power inverter?



For this 8kw inverter, better use 0awg battery cable, otherwise it will become very hot & effect the efficiency, tks.

How long i can use if I want to run my 1000w freezer?

How long i can use if I want to run my 1000w freezer with inverter?

watts=volts x amps, 1000w/12v=83amp, if your battery is 200amp,

200/83=2.4hour, 2.4 x 70%(battery condition & efficiency)=1.6hour around

What is peak surge power?

What is peak surge power?

Some motor appliance need 10-15 times to turn on the appliance, means if the motor mentioned 100w, then need 15 times big power inverter to turn it on, this is the peak surge power.

What is the best position to secure the inverter? 1. Flat on a board? 2. Horizontally against a wall? 3. Vertically, fan up or down?

What is the best position to secure the inverter? 1. Flat on a board? 2. Horizontally against a wall? 3. Vertically, fan up or down?

All are ok, just keep it well ventilated, thank you.

What kind of battery do you recommend to use with this 3KW power inverter?

What kind of battery do you recommend to use with this 3KW power inverter?

For this 3KW power inverter just use it with Lead-acid battery, like Gel U.S.A or A.G.M1 or A.G.M2

When the fan will turn on automatically?

When the fan will turn on automatically of the power inverter?

When inside go to 70℃, will auto start to cool the temperature.

Can I use circuit breaker instead of a fuse to fit into the positive side from the battery?

Can I use circuit breaker instead of a fuse to fit into the positive side from the battery?

Q: Hi, I recently purchased this 3000w LF inverter from you, I am just about to fit this into my motorhome, can you advise what size fuse I need to fit into the positive side from the battery? could I use a circuit breaker instead of a fuse???
thank you.
A: Hi, can not use fuse, but can use circuit breaker instead.

Why better do not use modified power inverter to run pump?

Why better do not use modified power inverter to run pump?

As pump or motor appliance have 15-20 times peak power require, modified power inverter only 2-times peak power, you may need try LF INVERTER to run this kind of appliance, tks.

How does the ATS function work on this 24v LF inverter?

How does the ATS function work on this 24v LF inverter?

ATS Function on 24v LF inverter:

a. when switch to ATS function, then: 

for 24v system, your battery voltage when 21.5v, 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 28v,  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 21.5V,  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.

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?

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.
