GT Power GT4000ESI 4000W/5kVA Inverter Generator Solar Backup Package

Inverter generators use advanced electronics to convert AC power to DC and back to AC, providing more stable, cleaner energy than conventional models. This makes them safer for sensitive devices like computers and smartphones. Additionally, inverter generators adjust engine speed based on load, improving efficiency and reducing noise. Conventional generators, on the other hand, operate at a constant speed, which consumes more fuel and produces louder noise. The engine on conventional generators must run at a fixed RPM (normally 3600rpm) to provide exact power (in NZ the power standard is 230V 50HZ) . This means that if the engine speed varies up or down by even 10%, this can change the voltage and frequency of the power output by 10%, which can damage appliances connected to the generator. 

The runtime of an inverter generator varies depending on the model and the load it's handling. For example, a smaller inverter generator might run for 6-8 hours at 50% load, while larger models can last 10-12 hours or more. The advantage of inverter generators is their ability to adjust fuel consumption to the load, so they can run longer on less fuel compared to conventional generators, which operate at a constant speed regardless of demand.

There are very few disadvantages of an inverter generator, as long as you invest in a quality machine. To withstand the rigors of running long hours in emergency situations, the complex electronics that are housed within an inverter generator need to be premium quality. One disadvantage of high-end inverter generators like Honda is that they very high cost, however there are other high-quality options like GT Power with equal quality and warranties that offer much better value. 

Inverter generators are significantly quieter than conventional models. They typically operate at around 50-60 decibels, which is comparable to a normal conversation. The reason they are quieter is that they don’t run at full speed all the time and are also often enclosed in compact, silenced casings, and electronically adjust their engine speed based on the load. In contrast, traditional generators can be as loud as 70-90 decibels, which is similar to the noise level of a lawnmower or a busy street. 

Inverter generators are considered more eco-friendly than conventional generators because they are more fuel-efficient, leading to reduced emissions. Many models also meet strict environmental regulations, such as CARB compliance. By adjusting engine speed based on the power load, they minimize unnecessary fuel consumption, which lowers both carbon emissions and fuel costs. In addition, their quieter operation makes them more suitable for use in noise-sensitive areas, contributing to a better environmental impact. 

An ATS provides several benefits:

• Minimises downtime by automatically switching power sources.
• Enhances workplace safety by preventing sudden equipment shutdowns.
• Protects sensitive equipment from power surges or fluctuations.
• Eliminates manual intervention, ensuring quick power restoration.
• Improves energy efficiency by optimising power usage.
