Calculating Wattage For Dual Refrigerator Operation

First, identify individual power usage to calculate the combined wattage for two refrigerators.

Typically, a fridge uses around 150 watts.

So, two would take roughly 300 watts.

However, startup wattage is a factor to consider.

At startup, fridges may require 800-1200 watts.

Therefore, ensure your generator can handle this initial power surge.

Next, add the wattage of any other appliances you plan to power.

Remember, these also have startup wattages.

Accumulate all these figures together.

If the total is less than 3500, your generator should cope.

It’s always prudent to leave a buffer.

This means your generator is not always running at full capacity.

Instead, aim for around 80% of its rated output.

This allows for any unexpected power surges.

In conclusion, always calculate your total power need.

Check each appliance and its startup wattage.

This ensures your 3500-watt generator can handle your household’s power demand.
