Introducing the state-of-the-art DC/AC Inverter Type with 300W Output Power, featuring an integrated UPS and Battery Charger, designed to meet your energy needs efficiently.
1. Product Introduction
Our UPS modified power inverter operates seamlessly with a standard input mains power of AC220V/AC110V, converting AC power into DC power to energize household electronic appliances and equipment. Simultaneously, it charges the connected external battery. During a power failure, the inverter instantly switches to transform the
battery's DC power into AC220V/AC110V and continues charging the battery, ensuring the uninterrupted operation of your
equipment and appliances, preventing any potential damage.

Frequency Asked Questions And Solution
Q1. The electric appliance doesn't work and the indicator light isn't on.
Reason:
1. Faulty battery.
2. Wrong connection of positive pole and negative pole.
3. Loose connection of the cables.
Answer:
1. Check the battery, and change it if needed.
2. Check the connection of battery. The inverter might be damaged and should
be changed or sent to be repaired.
3. Check the cables and connection points, and tighten the terminals.
Q2. The electric appliance doesn't work and the RED indicator light is on.
Reason:
1. The rated power of electric appliance exceeds the nominal power of inverter
which leads to over load shut down.
2. The rated power of electric appliance is less than the nominal power of the inverter
but its peak power is too high which leads to over load shutdown
3. The electricity in battery runs out (the inverter alarms)
4. Poor ventilation causes over heat shutdown
5. Input voltage is too high.
Answer:
1. Please use the electric appliance which power is less than the nominal power of inverter.
2. The peak power of electric appliance is no more than that of power inverter, or the same power.
3. Charge the battery or change it.
4. Turn off the inverter for 15 minutes, remove the items near fan and those around the inverter,
and put the inverter in a shady and cool place
5. Turn off the inverter and test the output voltage of battery.
Q3. The output voltage of power inverter tested is too low.
Reason: Generally the numerical reading range of voltmeter for testing use is too small.
Answer: If you test the output voltage of modified sine wave inverters, please use "true RMS
Muti-meter" to obtain the accurate data.
Q4. Only small power load can be driven.
Reason: When the current goes through the cables, the voltage declines.
Answer: Shorten the length and use thicker cables.
Q5. The hours of use are too short.
Reason:
1. The electricity consumption of the electric appliance exceeds the rated load capacity of the power inverter.
2. The battery is faulty or damaged.
3. The battery is not fully charged.
4. The current diminishes when passing through cables.
Answers:
1. Utilize a battery with a larger capacity.
2. Replace the battery.
3. If the charger cannot fully charge the battery, upgrade to a superior intelligent charger.
4. Reduce the length of the cables and opt for thicker cables.
Q6. How to contact your esteemed company to purchase the inverters?
Reason:
Although we are in different regions, we aim to establish a long-term business relationship with your esteemed company and your exceptional
products.
