Running Multiple Devices – Calculating Total Wattage

When powering multiple devices from a single power source like a generator or inverter, it is important to calculate the total wattage to ensure you do not overload the system.

First, determine the running or operating wattage of each device, which can usually be found on a label or in the product specifications. Be sure to use the actual wattage under typical usage conditions, not maximum wattage.

Add together the running wattage of all devices that will be powered simultaneously. It is also advisable to add 10-20% to this total as a safety buffer. Exceeding the rated wattage capacity can trip breakers, damage equipment, or create fire hazards.

Properly sizing the system by calculating total wattage ensures safe, reliable operation when running multiple devices. Consider starting watts as well for items with motors like refrigerators or pumps.

With some planning and basic math, you can safely power multiple devices from a single power source.

The main limitation of 3500 watt generators is running high wattage devices simultaneously. To avoid overloading your generator:

  • Add up the running (rated) watts for all appliances and tools you plan to run at once. This is your total wattage draw.
  • Compare the total wattage to your generator’s capacity. A 3500 watt generator can safely output about 3000 watts continuously.
  • Avoid exceeding 80% of the rated capacity to leave a safety buffer. For a 3500 watt generator, try to keep total draw under 2400 watts.

You can also stagger usage of high-draw appliances like microwaves, air conditioners, and power tools to stay within the generator’s limits. Run them one at a time along with several low-wattage items.

Prioritize essentials like fridges, freezers, phone chargers, and medical devices first when fuel or power is limited.

 

Generator Size Recommendations

When selecting a generator, properly sizing the unit is crucial for safety and performance. Portable generators typically range from 800W to 17,000W, while standby whole-house generators go up to 60,000W or more.

For portable generators, first compile a list of essential devices and their running watts. Add these together, then add the highest starting wattage of a motorized appliance for the total watts needed.

Increase the total by 10-15% as a safety margin. Standby generators should be sized by an electrician based on the home’s total electrical load. They require professional installation and hookup to a home’s breaker panel.

Consider frequency of outages, fuel type, and noise levels too. Undersizing risks overload and failure, while oversizing wastes money on unnecessary capacity. Properly sizing your generator ensures reliable backup power when you need it most.

  • For basic backup power for lights, phones, fridge, TV and internet, a 3000-3500 watt portable generator is usually sufficient. This range can also handle RV and job site power needs.
  • To run high wattage devices like home AC, electric stove, or well pump, consider a 5000-6500 watt standby generator. These can power more appliances simultaneously.
  • For whole house coverage during outages, an 8000+ watt standby unit is recommended. Get a generator transfer switch installed to connect it to your home’s electrical system.

Always check the wattage requirements of the items you want to run and add at least 20% more capacity for safety. Undersizing your generator can lead to overload and damage.
