Why Battery Storage Is Often Not Covered
Solar panels are increasingly understood by insurers, but battery storage is newer territory. Three coverage gaps are especially common:
- Not listed as covered property: Older policies written before battery storage became common may not explicitly cover energy storage systems.
- Mechanical breakdown exclusion: If your battery fails due to a manufacturing defect or software issue (not a covered event like fire or hail), standard policies won't pay.
- Fire caused by battery: Some insurers are concerned about lithium-ion fire risk and may have exclusions or surcharges related to battery storage.
Coverage Costs by Battery Type (2026)

| Generic / Wholesale | $5,000–8,000 | $50–90/yr | Brand matters for insurer acceptance |
How to Confirm Your Battery Is Covered
- Call your insurer and ask specifically: "Is my [brand] battery storage system covered under my dwelling policy at replacement cost value?"
- If yes, ask them to send written confirmation and update your declarations page to include the battery by make/model.
- If no, request a battery storage endorsement or rider — most major insurers offer one for $60–130/year.
- Also ask about equipment breakdown coverage as a separate add-on — this covers failure due to mechanical or electrical breakdown, not just physical damage.
Frequently Asked Questions
Does homeowners insurance cover a Tesla Powerwall?
A Tesla Powerwall can be covered under your homeowners policy as part of your dwelling's electrical system, but you must confirm this with your insurer and ensure your dwelling coverage limit includes the battery's value (~$11,500 for Powerwall 3). Many standard policies require a specific battery storage endorsement.
What happens if my solar battery catches fire?
If fire damage is caused by your battery, your homeowners policy should cover resulting damage to your home under standard fire coverage. However, some insurers have added exclusions or surcharges related to lithium-ion battery risk. Review your policy's fire coverage language.
Is equipment breakdown coverage worth it for solar batteries?
Yes, for most homeowners. Equipment breakdown coverage costs $25–50/year and covers electrical or mechanical failure of your battery that isn't caused by a covered peril. Since inverters and batteries can fail outside of weather events, this fills a critical gap in standard coverage.
