For your parties, weddings, and events
For an outdoor event without access to the grid, a 3000W generator is ideal for:
Decorative LED lighting: 10–100W (per installation)
DJ sound system: 500–1200W
Video projector, string lights: 300–600W
This provides complete autonomy for a successful event, even far from any power outlet.
What are the different types of 3000W generators?
1. Gasoline (petrol or diesel)
Gasoline: Faster start-up, lower noise, suitable for short or occasional use.
Diesel: More durable, suitable for extended use, but generally heavier and noisier.
Advantages:
Autonomous, quick to start
Available everywhere
Disadvantages:
Noise, CO₂ emissions
Requires regular maintenance
2. Solar generator (solar station)
Operation:
Operates using an internal battery, recharged by solar panels or mains electricity.
Advantages:
Quiet, environmentally friendly, fuel-free
Ideal for sensitive devices (electronics, CPAP, refrigerator, etc.)
Disadvantages:
Depends on the sun or mains electricity
Limited capacity if the battery is not expandable
How to Choose a 3000W Generator?
Assess Your Energy Usage
Before choosing a generator that's right for your needs, it's important to assess your energy consumption. Then, consider several essential criteria to make the right choice.
To estimate your electricity consumption, start by making a list of all the electrical appliances you use at home. Then, indicate the consumption of each one. You can then calculate your average consumption, in kilowatt-hours (kWh).
Another simple way to determine your annual energy consumption is to look at your electricity bills.
If you opt for a solar model, it's essential to also consider its lifespan, which mainly depends on the type of battery it has.
What is the lifespan of a solar generator?
The longevity of a solar generator depends on the number of charge and discharge cycles it can perform. The higher this number, the longer the device will last. Another key factor is the type of battery technology used during its manufacture:
Lead-acid battery: approximately 400 to 500 cycles
AGM battery: between 600 and 900 cycles
GEL battery: between 800 and 1,200 cycles
LiFePO4 (lithium iron phosphate) battery: between 2,000 and 3,000 cycles
Lithium-ion battery: between 3,000 and 6,000 cycles
Ferronickel battery: up to 4,000 cycles
