Keeping the refrigerator running is often a priority for a PG&E household considering solar and battery backup. Make that goal specific: identify every cold-storage appliance, confirm its circuit is supported and plan how you will check temperatures if power is interrupted.
A suitable solar-plus-battery PPA can help put that equipment plan within reach without an upfront purchase, where the household and offer qualify. These utility and food-safety resources were checked September 11, 2026.
Include the refrigerator and any separate freezer
Give the installer the model information for the kitchen refrigerator, garage freezer and any other appliance you want backed up. Identify their actual outlets. Equipment in another room or building should not be assumed to share the kitchen's backup circuit.
PG&E's battery guidance explains that many systems supply selected circuits. Ask the designer to confirm which appliances can start and operate together, alongside lights, communications and other essentials.
Request a duration estimate for the whole supported load, including overnight conditions. Starting charge, reserve, household demand and solar availability affect the result. Solar can replenish storage only when sunlight and compatible backup operation permit; a refrigerator on the circuit list is not a promise of unlimited refrigeration.
Prepare a temperature check before an outage
The FDA's outage guidance recommends appliance thermometers, with the refrigerator at 40°F or below and the freezer at 0°F or below. It also recommends preparing ice or frozen containers of water and having coolers available.
Use those preparations alongside the battery. The system app describes electrical operation; a thermometer helps you assess the appliance's temperature. Follow the appliance manufacturer's instructions and keep a record of any interruption that affects cooling.
PG&E's outage-safety page advises keeping refrigerator and freezer doors closed and stocking shelf-stable food. Plan meals that minimize repeated door opening while you monitor the situation.
Know what to do if backup stops
If the supported appliance loses power, note the time and contact the installer about unexpected system behavior. Follow your food-storage plan rather than waiting solely for the utility's estimated restoration time.
FoodSafety.gov's outage chart, last reviewed August 8, 2024, says an unopened refrigerator keeps food safe for up to four hours without power. It advises discarding refrigerated perishables such as meat, fish, eggs and leftovers after four hours without power. Never taste food to decide whether it is safe; use the chart's item-specific guidance and discard it when in doubt.
These are food-storage guidelines, not battery-runtime estimates. Restored electricity does not establish that food remained safe during an earlier cooling interruption. Check temperatures and the interruption history before deciding what to keep.
Make refrigeration part of the written PPA scope
The CPUC's consumer guide explains that the provider owns the solar system and charges for its generated electricity. Confirm that the qualifying no-upfront offer includes the battery, backup controls and electrical work for the agreed appliances.
Review battery ownership, installation charges, maintenance and replacement coverage, ongoing payments, the rate, any escalator, term and home-sale provisions. Include remaining PG&E charges in the budget. No upfront purchase does not mean free electricity, guaranteed savings or guaranteed protection from food loss.
