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.
Los Banos is a rapidly growing city of about 45,000 residents in western Merced County, located along Interstate 5 and Highway 152. Served by ZIP code 93635, Los Banos is one of the fastest-growing cities in the Central Valley. Summer temperatures regularly hit 95–105°F, and PG&E bills for a typical home run $200–$400 during peak cooling months. The flat valley setting provides excellent solar exposure. Robbins Energy serves all of Los Banos and Merced County.
Newer suburban homes often have 200-amp panels and solar conduit pre-runs — making Powerwall 3 installation faster and cleaner. The built-in solar inverter means no separate string inverter is needed for new solar + battery installations.
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. Suburban communities typically have newer housing stock with 200-amp panels and good solar access. Newer developments may have solar conduit pre-runs.
Permits issued by: City of Los Banos 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. Merced County permits process through the County Building Department or city building departments. Robbins Energy handles the full process.
