What size solar generator do I need? This question is becoming increasingly important for many consumers across the European Union. Whether you live in Germany, Italy, France, Spain, the Netherlands, or other EU nations, choosing the right solar generator ensures reliable power for outdoor activities, road trips, home backup, and emergencies.

In this comprehensive guide, we explain how to calculate the ideal solar generator size, explore different usage scenarios, and recommend suitable models such as the IEE P3200, IEE P2400, Oscal PowerMax 1800, PowerMax 2400 Pro, PowerMax 3600, and PowerMax 6000.

How to Determine the Right Solar Generator Size

The size of the solar generator you need depends mainly on:

• Your power consumption (Wh or kWh per day)
• The appliances you want to run
• The duration of use (hours per day)
• Whether you use solar panels to recharge daily

Step 1: Identify the Power Consumption of Your Devices

Check the wattage labels or manuals of your appliances. Here are common examples:

Step 2: Calculate Total Energy Use (Wh)

The formula is simple:

Energy (Wh) = Device Wattage × Usage Hours

For example: A 60W cooler used for 5 hours:

60W × 5 = 300Wh

Step 3: Choose a Generator With 20–30% Extra Capacity

Solar generators should not be discharged to 0%. A safety margin ensures longer battery life and better performance.
