What falling LFP battery prices change for installers: Cheaper storage shifts the conversation from capacity to integration.
As LFP pack prices fall, storage stops being the luxury line item on a quote and becomes a default option. That changes what customers ask and what installers must be able to answer.
Three shifts to expect
- Customers compare cycle life and warranty instead of headline capacity.
- Integration quality, chargers and firmware compatibility become the differentiator.
- Quotes that include storage from the start win more often than upsell attempts.
The teams that train on integration now will be the ones quoting storage as routine next year.
