What Is Tesla Powerwall 3?

The Tesla Powerwall 3 is a 13.5 kWh lithium iron phosphate home battery with a built-in 11.5 kW solar inverter. It stores solar energy for evening use, provides whole-home backup during outages, and integrates with the Tesla app for real-time monitoring. A single Powerwall 3 can back up most Central Valley homes; two units cover high-load households with EV charging.

Who Is It Right For?

  • Homeowners with existing solar who want battery backup
  • New solar + battery installations (Powerwall 3 includes the inverter)
  • Households with medical equipment requiring outage protection
  • EV owners who want to charge from stored solar overnight
  • Homes in PSPS-risk areas (foothills, rural Fresno/Madera/Tulare counties)

Problems It Solves

  • PG&E outages during summer heat events and PSPS events
  • High evening electricity bills under NEM 3.0 (store solar, use at night)
  • Eliminating grid dependence for households with high AC loads
  • EV charging from solar surplus rather than grid power

Key Specs & Highlights

  • 13.5 kWh usable capacity per unit — stackable up to 4 units
  • Built-in 11.5 kW solar inverter (no separate inverter needed)
  • 97.5% round-trip efficiency
  • Whole-home backup capable — not just critical loads
  • Tesla app monitoring with real-time energy flow
  • Storm Watch mode — auto-charges before PSPS events
  • 10-year warranty

Installation Details for Central Valley Homeowners

System Sizing

One Powerwall 3 (13.5 kWh) covers essential loads for 12–24 hours for most Central Valley homes. Two units are recommended for whole-home backup including AC, or for households with EV charging. Robbins Energy sizes battery systems based on your actual PG&E usage data.

Solar Integration

Powerwall 3 includes a built-in solar inverter — for new installations, no separate string inverter is needed. For retrofits onto existing solar systems, a Gateway 2 or Backup Switch is required. Robbins Energy handles both new installs and retrofits.

Backup Power

Powerwall 3 supports whole-home backup — not just a critical loads panel. During a PG&E outage, your home transitions to battery power in under 20 milliseconds. Storm Watch mode monitors PG&E outage alerts and pre-charges the battery before a PSPS event.

Panel & Electrical

Powerwall 3 installation requires a 200-amp main panel. Homes with 100-amp service (common in older Fresno, Madera, and Tulare County neighborhoods) need a panel upgrade first. Robbins Energy performs panel upgrades as part of the installation.

Permitting & Interconnection

Battery storage installations require a building permit and PG&E interconnection approval in all Central Valley jurisdictions. Permit timelines vary: Fresno and Clovis typically 2–3 weeks; rural county jurisdictions 3–5 weeks. Robbins Energy handles all permitting.
