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.
Fowler is a small community of about 6,500 residents located 12 miles south of Fresno along Highway 99. Served by ZIP code 93625, Fowler is a tight-knit agricultural community with a mix of older downtown homes and newer residential developments. The flat San Joaquin Valley setting provides excellent, unobstructed solar exposure — most Fowler roofs have clear south-facing orientation with minimal shading. Summer temperatures regularly hit 100–107°F, and PG&E bills for a typical Fowler home run $180–$320 during peak months. Fowler's proximity to Fresno means Robbins Energy crews can reach the city quickly, and the Fresno County permit process applies to most Fowler installations.
Valley floor cities like Fresno and Clovis have lower PSPS risk but high summer electricity rates. Powerwall 3 maximizes your NEM 3.0 solar value by storing midday production for evening use — avoiding PG&E's peak rates from 4–9 PM.
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.
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.
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.
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. Valley floor cities typically have flat terrain with excellent south-facing roof exposure. Most homes have unobstructed solar access. Older neighborhoods may have 100-amp panels requiring upgrade.
Permits issued by: City of Fowler Building Department. 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. PG&E NEM 3.0 interconnection required. Robbins Energy handles the full interconnection application, which typically takes 4–8 weeks for approval after permit issuance.
Flat valley terrain means most rooftops have near-ideal solar orientation. Minimal shading from trees or neighboring structures in most neighborhoods. Older stock. Many homes have 100A panels needing upgrade.

Under PG&E NEM 3.0, battery storage is essential to maximize the value of your solar investment. Export rates are low; storing solar for evening use avoids buying power at peak rates (4–9 PM). In Fowler, summer electricity rates peak in the evening when solar production has stopped — battery storage lets you use your own solar power instead of buying from PG&E at peak rates.
This valley floor community has low PSPS risk. Battery storage is still valuable for NEM 3.0 optimization — storing midday solar for evening use instead of selling back at low export rates. Low-moderate. PSPS events rare. Summer grid stress occasional.
Powerwall 3 (released 2024) includes a built-in 11.5 kW solar inverter — for new solar installations, no separate string inverter is needed. Powerwall 2 required a separate solar inverter. Powerwall 3 also has higher continuous power output (11.5 kW vs 5 kW) and supports whole-home backup more effectively. Robbins Energy installs Powerwall 3 for new systems and can retrofit Powerwall 2 onto existing solar.
Yes — Powerwall 3 is designed for whole-home backup, not just critical loads. A single unit (13.5 kWh) can power most Central Valley homes for 12–24 hours depending on AC usage. Two units cover high-load households with EV charging. During a PG&E outage, your home transitions to battery power in under 20 milliseconds — most appliances don't even notice the switch.
Battery storage systems installed with solar may qualify for the federal Investment Tax Credit (ITC). Tax credit eligibility depends on your individual tax situation. Robbins Energy recommends consulting a tax professional for guidance specific to your circumstances. We do not provide tax advice.
