Portable generator accessories 

Maintenance Kits (link)

• Schedule maintenance is a necessity for all portable generators. The portable maintenance kits offer all the components necessary to perform complete maintenance on Generac portable generators. Oil will need to be purchased separately based on the recommendations listed. Maintenance is recommended seasonally but may differ per model. More frequent service is required when operating in adverse conditions. Refer to the generator owner's manual for more information. 
• Items included (if applicable).
  • Air filter, oil filter, spark plug(s), oil funnel, chamois, Stabil sample, spark plug wrench. 

Note: Contents of each maintenance kit vary by model. Check your user manual to verify which maintenance kit you should buy, or reach out to your local service dealer.

Manual Transfer Switch (link)

• Manual Transfer Switches allow you to connect your portable generator to hardwired appliances. Ensure essential items like your furnace, sump pump, or lights are backed up by your portable generator during an outage.

Power Inlet Boxes (link)

• Power Inlet Boxes (PIB) allow owners to safely connect their portable generator to a manual transfer switch. When the power goes out, they simply plug one end of a power cord into their generator and the other into the PIB.

Generator Plugs and Connectors (link)

Extension Cords (link)

• Heavy duty generator extension cords with multiple connection ports for generators with 20 and 30 Amp outlets.
• Generator cords for manual transfer switch/ power inlet box connections. 

Does Generac sell running covers for portable generators?

Generac does not recommend using a running cover, enclosure, or other type of covering while a portable generator is operating. Portable generators must be operated outdoors in an open, unobstructed area so they can cool properly and safely vent exhaust.

• For additional details, see: Does Generac recommend a running cover for their portable generators?

If you need weather protection, refer to your owner’s manual for operating guidance and consider using a moisture-resistant cover only for storage when the generator is off, cool, and properly dried.

• See: How Do I Prepare My Portable Generator for Storage?

Disclaimer: Third-party covers or enclosures that restrict airflow, trap heat, or interfere with safe exhaust routing can create safety hazards and may cause damage. Damage caused by improper operation or non-approved accessories may not be covered under warranty. For warranty information, see Where can I find warranty information about Generac Products?.

Home standby generators already include an all-weather enclosure. Generac does not recommend placing a standby generator in a secondary enclosure. If the enclosure panels are damaged and you need replacement parts, use the product lookup page to find parts lists, or contact a Generac Independent Authorized Service Dealer (IASD) for ordering and service.

• See: Can I put my home standby generator in a secondary enclosure?

Optional Accessories

• Switched Neutral Kit
• Flush Mounting Plate
• Power Inlet Box Flip Lid -This optional flip lid is intended for applications where covering the power inlet is desired, such as keeping out nesting insects, dirt, moisture, etc. (The Power Inlet Box is sold separately).

General air-cooled home standby generator accessories

Check you user manual to verify accessories that are compatible with your specific generator model.

Batteries

Battery selection depends on your generator model, and in some cases, the controller. See this article for more information.

26R Wet Cell Battery 

• This battery is used by Guardian series and older generator models.

35AGM Battery

• This battery is an alternative recommendation to the standard 26R. This is a maintenance-free style battery.

Cold Weather Accessories

• Battery Pad Warmer
  
  • The pad warmer rests under the battery. It is recommended for use if the temperature regularly falls below 0°F (-18°C). 
• Breather Warmer
  • The breather warmer is for use in extreme cold weather applications. This is for use with Evolution controllers only in climates where heavy icing occurs.
• Oil warmer
  • The oil warmer slips directly over the oil filter. It is recommended for use if the temperature regularly falls before 0°F (-18°C).
• See the following article on cold weather accessories for more detailed information on components and compatibility.

Auxiliary Transfer Switch Contact Kit
