David questioned the logic of buying a small emergency battery when electric cars have larger power sources. The proposed system would use solar panels to charge vehicles during outages, with cars powering homes when needed. However, current systems present significant limitations.
GM's V2H system discharges only, without recharging the car. Ford's F150 Lightning marketing promised backup power, but the required Charge Station Pro is no longer sold. Kia's Wallbox Quasar 2 faces customer implementation issues and prevents simultaneous solar charging.
The only current viable option involves Tesla Powershare with a Cybertruck, allowing solar recharging during outages. Enphase plans a bidirectional charger targeting volume production in Q4 2026, but availability may slip to 2027. The author, unwilling to wait, considers a smaller emergencies-only battery instead.
With no electric car currently owned—a 2013 Honda Fit—the family contemplates a plug-in hybrid or full EV for future needs, though they question suitability given minimal driving and long trip patterns.
