What types of cold weather accessories are available?
Air-cooled home standby cold weather accessories
Battery pad warmer
Purpose: Helps maintain battery temperature to support starting performance in extreme cold.
Why it's helpful:
-
- Batteries can lose efficiency or freeze in extreme cold, reducing starting power.
- Adding warmth supports reliable starts and can extend battery usability in cold weather.
- Compatible with units manufactured from 2008–present.
- Not necessary for AGM-style batteries when used with Guardian-series generators. These are recommended for use with AGM batteries for Next Generation models.
- Recommended for regions regularly experiencing temperatures below 0 °F.
- Part numbers: G0071010 (Guardian Series), G0072110 (Next Generation Series). For 7.5 kW PowerPact units, this item is included in the Cold Weather Kit (part number 6808-1).
Oil filter warmer (oil warmer)
Purpose: Helps keep engine oil flowing by reducing the chance of thickening around the oil filter in cold temperatures.
Why it's helpful:
-
- In freezing conditions, engine oil can become more viscous, making circulation harder.
- A warm oil filter supports smoother oil flow, reducing engine strain during starts.
- Compatible with units manufactured from 2008–present.
- Part numbers: G0071020 (Guardian Series), G0071021 (Next Generation Series).
Breather warmer
Purpose: Helps prevent ice formation in the breather system and maintains proper airflow/venting.
Why it's helpful:
-
- Moisture can freeze in sub-zero temperatures, causing blockages and performance issues.
- Added heat reduces ice buildup risk to help maintain airflow in extreme cold.
- Suitable for extremely cold climates where heavy icing occurs.
- Compatible with units manufactured from 2008–present.
- Part numbers: G0071030 (Guardian Series), G0071032 (Next Generation Series).
Liquid-cooled home standby cold weather accessories
Consult the unit’s service documentation or an IASD for liquid-cooled accessory options and compatibility.
Who are these accessories recommended for?
- Regions where winter temperatures routinely fall below 32 °F.
- Extreme-cold areas with regular sub-zero conditions or heavy icing.
Who can install the cold weather kit?
- In addition to installing a battery with higher CCA (cold cranking amps), cold weather accessories are recommended in regions where temperatures regularly fall below 32 °F (0 °C).
- When installing any cold weather item, replace engine oil with either Generac 5W-20 full synthetic oil or 5W-30 full synthetic oil.
- Connection points vary by model. Consult the owner’s manual for complete instructions or use the dealer locator to contact a Generac service dealer for installation help.
- Accessory thermostats typically switch ON at 40 °F (4 °C) and OFF at 55 °F (13 °C).
Why are these accessories helpful in cold weather?
- Improve starting performance and reduce mechanical strain in low temperatures.
- Help maintain proper lubrication, airflow, and battery readiness.
Which units are compatible with cold weather kits?
Compatibility varies by model, production year, and controller. Connections may differ for older, non-Nexus/Evolution panels. For controller-specific or legacy model guidance, contact an IASD or Generac Customer Support (888-436-3722).
AGM batteries and battery pad warmers
Battery warmers are not recommended with AGM-style batteries when used with Guardian-series units. When used with Next Generation standby generators, battery pad warmers for AGM-style batteries are recommended.
Where can I purchase a cold weather kit?
- Use the dealer locator to find a local Generac dealer.
- Ordertree and other retailers may carry individual accessories by part number.
