Most appliances like CFL, fans, motor-based equipment like air conditioners and pump sets are designed to work on 50 Hz sine waves. Running such types of equipment on unregulated quasi sine wave-square wave-based inverters poses a risk as regards performance and durability.

To avoid such mishaps, one must get a proper inverter for their appliances and keep them safe and in working condition throughout the year. Lento uses pure sine wave technology in their inverters, UPS and power supplies. The Sine wave inverters output stable frequency and voltage, mimicking mains power supply, making it perfectly suitable to power expensive equipment, especially inductive loads that do not work well on square waves.

Lento DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, Lento’s inverters and UPS are designed to deliver instantaneous high current during start-up, especially in the case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.

FAQ-

How much will a 3000 watt inverter power?

This is the maximum current that your inverter can draw. Based on this ampere rating, you must size your batteries. The output ampere is typically 13A for a 3000-watt inverter in a 230V power system. This output can run 20-30 ceiling fans, 2-3 refrigerators, and 10-15 large TVs.

What is a 3000 watt inverter good for?

Household Appliances

A 3000 watt inverter can handle about 2500 watts at once to avoid overloading. It's strong enough for refrigerators, microwaves, and washing machines, for example, a fridge uses 600-800 watts, a microwave 1000-1500 watts, and a washer 1500 watts.

How long will a 200Ah battery last on a 3000W inverter?

Runtime = (200Ah × 48V × 0.9 × 0.95) / 1000W = 8.2 hours. For a 2000W Inverter, the runtime is 4.1 hours. Runtime = (200Ah × 48V × 0.9 × 0.95) / 2000W = 4.1 hours. For a 3000W Inverter, the runtime is 2.7 hours.

Can a 3000W inverter run a fridge?

A 3000W inverter generator is a good home backup solution. It'll run most household appliances, such as refrigerators, freezers, space heaters, and microwaves.

Will a 3000W inverter run a TV?

Laptop: 50-100W. Television: 100-400W. Electric Grill: 1000-1500W. Efficiency: Modern 3000W inverter are manufactured with pure sine wave technology that provides clean and stable power to protect your electronic devices from possible damage.

Can a 3kW inverter power a house?

3kW to 5kW Inverters: Ideal for medium-sized homes with average energy consumption. These inverters can handle multiple appliances, including refrigerators, TVs, and air conditioning units. 6kW to 10kW Inverters: These inverters are best for larger homes with higher energy demands.

How much will a 2000 watt inverter power?

With the 2000 watt inverter at hand, you will be able to power a plethora of household electronics and appliances such as laptops, microwaves, lights, TV, and microwave among others.
