The test results have been recorded on video and compared with information from manufacturers and users. If you want to know the differences between the generator you use and the Wattsun battery system, contact one of our specialists, and we will provide you with a customized calculation.

In the first part of this blog, we will look at the differences in ease of use and sustainability between a generator and a battery system. In part 2 of our blog, coming soon, we will delve deeper into cost savings.

The difference in ease of use

Both the generator and the Wattsun battery system are highly suitable for on-site use. Both provide 230 volts and are portable. A generator is a device that produces electricity by converting fossil fuels such as diesel and gasoline into power through a combustion engine. The Wattsun is a lithium-ion battery system that stores electricity for later use, ensuring you always have power when you need it.

Starting a generator is not easy. Firstly, the generator must be placed on a stable, horizontal surface, as tilting it too much can cause problems. Before the generator can be used, the oil level and gasoline level must be checked. Then the process of starting the engine begins, involving several steps: first, open the gasoline tap, turn the choke, switch the engine switch to ON, gently pull the recoil starter, and finally, as the engine starts to warm up, gradually close the choke.

Check the manual for a generator: it is filled with warning signs, there is a risk of burns, and the sequence of actions is crucial. In short, a time-consuming task and a hassle for both beginners and experienced users. Additionally, the generator is a bulky and heavy device. A small generator can easily weigh 43 kg! This makes installing your power source a heavy task, almost impossible to do alone.

The Wattsun battery system is a complete solution. Plug & play. As a user, you simply turn on the battery system by holding down the on/off button briefly. Plug your electric device into the Wattsun’s socket, and you have power immediately. The Wattsun is designed so that a module weighs no more than 17 kg. This makes the product quick and easy to move and usable anywhere.

Refuel or stack

A common issue with many generators is not knowing how long you can still use your power supply. When the fuel is running out, you need to turn off the generator before refueling. The significant disadvantage is that you have to turn off all your electrical devices, which is a waste if your work comes to a halt.

To increase the capacity for your tasks, you can easily extend the battery system’s operating time by stacking the modules, thereby increasing the battery capacity. This allows you to take the desired amount of energy for each job. Stacking can even be done during use without turning off the power, ensuring your work never comes to a standstill.

Quiet power or noise

A generator generates a lot of noise. The average generator produces around 90 decibels of noise due to the combustion engine. This is not pleasant to work beside and often causes noise disturbances for others, which you don’t want.

The Wattsun Dock and Wattsun Pack are almost silent; you only hear the fan, allowing you to carry out your work undisturbed.

Green power or fossil fuel

Emissions… When using a generator, the combustion of diesel or gasoline results in significant emissions of carbon dioxide (CO2), nitrogen oxides (NOx), and soot (PM). This substantial emission, along with mobile machinery, is responsible for 10% of total air pollution in urban areas. Working near a generator guarantees a lot of nuisance from both odor and noise, affecting others. This makes the working environment very unhealthy.

Batteries, such as Wattsun’s Docks and Packs, can be charged in advance with green power. They produce no emissions, and the working environment is much cleaner. You can effortlessly use this power supply indoors. Additionally, you don’t need to lay meters of cables from location to location. You can place the Wattsun Dock directly where you need the power. If you charge the battery with grey power, you emit between 10 and 17 times less CO2 than with a generator. Charging the battery with green power allows you to work entirely emission-free!

Maintenance of a generator and a battery

While a battery requires very little maintenance, a generator needs to be maintained very regularly. The generator’s engine oil needs replacement within the first hundred hours. This is an unpleasant task where it is best to use an oil suction device, and the old oil must be collected and disposed of responsibly. The oil filter needs replacement after 200 hours. Air filters and fuel filters also need to be replaced annually with regular use. An additional drawback is that maintenance takes time. You can outsource it, but this means you cannot use your generator for several days, and maintenance costs can add up.

The innovative battery system from Wattsun requires little maintenance. As long as you clean the housing occasionally and clean the dust filters twice a year, you have little to worry about with the Wattsun Dock and Wattsun Pack. It is important to charge a battery to about 50% before storing the module for an extended period. Also, ensure a dry storage space with an ambient temperature between 15 °C and 25 °C.
