A credible US home battery quote separates usable capacity, inverter output, installation scope and every named incentive, then models savings from your own utility import and export rates—not a generic national household.
The numbers every quote should expose
Start with the final installed price, usable battery capacity, continuous inverter output, warranted throughput, expected annual cycles, utility import rate and export compensation.
- Usable rather than nominal capacity
- Final price after confirmed incentives
- Battery and inverter model numbers
- Backup circuits and transfer equipment
- Permitting, interconnection and electrical work
- Product, performance and workmanship warranties
Demand proof for every incentive
Ask for the exact federal, state, tribal or utility program name, eligibility rule and dollar amount. A sales discount is not a government incentive, and an expired credit should never appear in a 2026 payback forecast.
Enter the final amount you are actually required to pay. Keep uncertain rebates outside the base case until the responsible agency or utility confirms eligibility.
Challenge the savings forecast
A stored solar unit can give up an export payment or net-metering credit. Savings come from avoided utility purchases minus that lost value, after round-trip losses.
If a quote assumes a full cycle every day, request the interval or billing data behind that claim. Oversized capacity cannot earn money while it sits unused.
