The feature ensures that when you are using this generator abroad, it automatically adjusts power output to match the voltage of your area. The Volt Lock feature automatically adjusts your voltage regulator to the proper setting when connecting the generator to your home AC system.

Fuel Economy Mode

Do you know that the Fuel Economy Mode feature of the Firman W03082 Inverter Generator will help you save your fuel up to 30 percent?

Fuel economy mode is a new feature from Firman W03082 Inverter, which helps you lower your fuel consumption by 30%. It doesn't only improve your generator's performance but also prolongs its lifespan.

The fuel economy mode provides consistent power output while prolonging engine life and fuel efficiency. It achieves this by reducing engine load under low load conditions, such as using light tools or appliances in your garage.

When you turn the generator on, the controller automatically surveys the current demand and starts the engine with less than the maximum load. The load drops to a pre-set level every time the generator senses no need for power.

This keeps the engine running at a lower speed and prevents overheating. After a set period, the controller will gradually increase the speed.

Running an inverter generator in economy mode will cause the engine to run at a lower RPM and increase fuel economy. This mode also reduces voltage output, so you should use power tools.

The W03082 runs at 3300 Watts in economy mode, 3000 Watts in normal mode, and 2800 Watts in high-performance mode.

Parallel Capable

The parallel capable feature of the Firman W03082 Inverter Generator that enables you to connect multiple units' power can be considered a significant advantage over other inverter generators in the market.

Sometimes you need more power than just one generator can offer. This is where parallel-capable generators come in handy.

A generator that is parallel capable has a built-in transfer switch that allows you to wire it directly into your home’s main electrical box. This means that you only need one plug to connect the whole generator to your home.

Electric Start

The built-in battery power can start the generator in five seconds with the electric start feature. After the generator starts, the engine alternator, which is 100% automatic, charges it.
