4. Inverter Generator

Nowadays, inverter generators have become one of the trendiest commodities people are purchasing for home-usage. There are many advantages of inverter generators like prolonged performance, portability and soundlessness.

The inverter generators work on the electromagnetic mechanism which produces AC. This current is automatically converted into DC and distributed to all the appliances.

Inverter generators are available at different prices and power outputs. It would be best if you chose one keeping your average electrical consumption in mind. The best trait for these inverters is the automatic charging feature.

These machines come in different sizes and you can choose the best one considering the price, output and size.

6. Standby Generator

The primary work of standby generators is to provide electrical back-up to any premise in case of a sudden power cut. No manual effort is needed to turn on the standby generators.

These generators are always connected to the main circuit and it ensures continuous flow of electricity wherever needed. Generally, standby generators run on combined fuel like diesel-gasoline, diesel-CNG, etc.

Hospitals, corporate offices, major industries prefer using standby generators for the convenience it provides. You can only buy this type of generator for your home only if it is vitally needed. Always remember that the standby generators are remarkably expensive.

7. Hydrogen Generator

Like solar generators, hydrogen generators also work in an eco-friendly manner as it consumes hydrogen as fuel. Although many scientists have tried to make a hydrogen-based electricity generator for years, it has recently reached the market.

These machines are portable and you can easily refuel them. However, hydrogen generators are expensive and rarely available in the market.

Hydrogen generators can work in the home or office. You can also carry it while travelling to a remote place. However, carrying hydrogen cylinders can be a challenging job.
