When it comes to powering large appliances like a 5-ton air conditioner, the EG4 Electronics’s 12kPV All-In-One Hybrid Inverter stands out for its capability and reliability. This advanced inverter is designed to handle substantial loads, ensuring that even the most demanding household appliances can start and run smoothly.
Additionally, a hybrid inverter like the 12kPV is defined by its ability to keep a system running even when the power is out. Whether you are looking to power a large air conditioner when the grid is down or manage your household’s energy consumption efficiently, the 12kPV inverter stands out as a reliable and robust solution.
Here’s an in-depth look from EG4 Electronics at how this remarkable inverter manages to start a 5-ton AC unit—without the need for a soft start.
Setup and Testing Process
To accurately simulate typical household loads and demonstrate the inverter’s capabilities, we set up a comprehensive testing environment. This included a configurable load bank to replicate real-world conditions, and connected to an oscilloscope with differential probes on both the high bus and the output bus. An amp probe was also used to measure the amperage throughout the process.
Inrush Current Measurement
Before engaging the configurable load bank, we began testing the inrush current on the 5-ton air conditioner. Inrush current refers to the initial surge of current required to start an electric motor, which can be significantly higher than the operating current. We set up the ammeter and started the AC unit, recording an inrush current of 137.4 amps. The oscilloscope data revealed a temporary dip in the high bus during this inrush period, which is to be expected during a surging start-up; however, it quickly stabilized as the system adjusted.
Managing Continuous Load
After measuring the inrush current, we loaded the 12kPV inverter with a total of 3 kW, distributed evenly across each leg (1.5 kW per leg). This setup simulates a typical household continuous load, as a television, fridge, microwave, chargers, and household lights running simultaneously typically consume around 3kW or less. With the breaker on, the 12kPV inverter managed the 3kW load seamlessly, showcasing its ability to handle consistent energy demands.
Restarting the 5-Ton AC Under Load
To further demonstrate the inverter’s robustness, we restarted the 5-ton air conditioner while the continuous 3 kW load was already running on the 12kPV inverter. Not only did the AC unit flawlessly start, but the sine wave observed on the oscilloscope showed only a slight dip in the high bus during the inrush. It quickly stabilized, confirming the inverter’s capability to handle significant surges without compromising performance.
The 12kPV Inverter: A Reliable Solution for Your Energy Needs
The EG4 Electronics 12kPV All-In-One Hybrid Inverter has proven itself as a powerhouse in managing large appliances and household loads. Its ability to handle high inrush currents and maintain stable operation under continuous load conditions makes it an excellent choice for residential energy needs.
Furthermore, a hybrid inverter like the 12kPV ensures your system keeps running during power outages. Whether powering a large air conditioner off-grid or managing household energy consumption, the 12kPV inverter is a reliable and robust solution.
