Fast, Reliable Solar Battery Storage & Backup Across Kingsburg
A properly sized battery system in Kingsburg typically runs $11,500-$19,800 installed, and most jobs we book are completed within two to three weeks of the permit approval. That’s the straight answer, and it holds up whether you’re on Draper Street near the old Swedish Village core or out on a one-acre parcel south of Sierra Street with a well pump pulling off PG&E’s AG-4B agricultural rate.
We’ve been working on Kingsburg rooftops long enough to know which ranch homes from the 1960s still have 100-amp panels, which ones got upgraded in the 1990s, and which neighborhoods lose grid power the longest on hot July afternoons when the San Joaquin Valley hits 108°F. If you’re tired of watching your solar array sit useless during an outage, call us at (877) 550-6892. A live person answers. Not a voicemail tree.
Key takeaways for Kingsburg homeowners:
- Battery storage for a typical Kingsburg ranch home: $11,500-$19,800 installed

Why Gus’s Solar Is Kingsburg’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis founded this company in 2011 and put his name on the building. He’s not a franchise owner in another state running a call center. When a Kingsburg homeowner calls about a battery that won’t hold charge after a fog season, Gus’s crew are the ones who show up, and Gus himself is the one who answers if something isn’t right.
We’ve done battery installs on ranch homes along 10th Avenue, newer construction off Kamm Avenue near the high school, and older bungalows by the railroad tracks. Kingsburg customers call us because the math gets quoted off their actual PG&E bill, not a glossy brochure estimate. Bring us a bill, we’ll bring you the math. Take two weeks to think about it. The price won’t change.
Background-checked, uniformed technicians arrive on schedule. Every roof penetration gets flashed properly. And when the system is live, Gus monitors it. If the production drops during tule fog season, he calls you before you call him.
Our Solar Battery Storage & Backup Services in Kingsburg
Tesla Powerwall Installation
A single Tesla Powerwall 3 installed in Kingsburg runs $13,200-$16,800 before any incentives. Two Powerwalls, which is what we recommend for homes running irrigation pumps or whole-house backup, land between $22,500 and $28,000. We handle the interconnection paperwork with PG&E, including the rapid shutdown requirements that trip up homeowners trying to DIY the filing.

Battery Retrofit for Existing Solar
Plenty of Kingsburg homes went solar between 2010 and 2018 and never added storage. That’s most of our battery work. We retrofitted a 1980s ranch home near the Swedish Village core with two Tesla Powerwalls after the homeowner’s legacy 200-amp panel couldn’t support a new irrigation pump. Our crew tied the Enphase IQ battery into the existing solar array, reconfigured the inverter’s rapid shutdown for whole-home backup, and set the system to discharge during PG&E’s 5-8 p.m. peak. The well motor now runs on stored solar instead of demand-charge power. A retrofit like that typically runs $12,000-$18,500 depending on the existing inverter brand and panel configuration.

Whole-Home Backup Power
For Kingsburg homeowners who want the refrigerator, well pump, HVAC, and lights all running during a PG&E shutoff, we size for actual load. Not a guess. We look at your historical usage, the startup surge on your pump motor, and whether your panel can handle the required disconnect clearances. Some older Kingsburg homes need a panel upgrade first, which we handle in-house. A whole-home setup with two batteries and critical-loads panel runs $21,000-$29,000 in this market.

Time-of-Use & NEM 3.0 Optimization
NEM 3.0 changed the export economics for every solar homeowner in Fresno County. If you’re on PG&E’s current net metering rules, your exported daytime power earns pennies, and your evening grid draw costs dollars. A battery lets you hold that midday production and use it at 6 p.m. During Kingsburg’s tule fog season from late November through January, we reprogram discharge schedules so you’re not pulling peak-priced grid power when your panels are barely generating. This programming is included with every battery install we do.

Trusted Brands We Service in Kingsburg
We work with Tesla, Enphase, FranklinWH, and Panasonic battery systems. If you have a SolarEdge inverter from a 2015 install, we can pair it with a compatible battery. If you’re starting fresh, we’ll spec what fits your home’s electrical panel and your actual usage. No brand loyalty for its own sake. FranklinWH’s aPower system has become a solid option for Kingsburg ranch homes with agricultural draws because the surge capacity handles well-motor startup without flinching. Parts for the common brands are stocked in our Central Valley warehouse, so a Kingsburg service call doesn’t wait on a shipment from out of state.
Common Solar Battery Storage & Backup Problems We See in Kingsburg Homes
- Undersized battery banks. Homeowners add a well motor or packing-shed evaporative cooler after the initial install, and the original Powerwall can’t cover the startup surge. The battery trips offline right when it matters. We size for future load, not just today’s bill.
- Tule fog season battery starvation. From November into January, solar production drops hard. Six to eight weeks of fog means a battery that never reaches full charge on NEM 3.0 export credits, leaving you on grid power at peak rates. We build winter production modeling into every Kingsburg proposal.
- 100-amp panel failures on interconnection. Older ranch homes in Kingsburg often still run 100-amp main panels. PG&E’s interconnection application for battery backup requires rapid shutdown and disconnect clearances that 100-amp panels can’t meet. We handle the panel upgrade as part of the battery install, not as a surprise change order.
- Improper transfer switching. We’ve seen installs from out-of-area companies where the critical-loads panel wasn’t wired correctly, and the refrigerator wasn’t on backup. After a PGE shutoff, that customer found out the hard way. We test every circuit before we leave the driveway.

FAQs - Solar Battery Storage & Backup in Kingsburg
A single Tesla Powerwall 3 holds 13.5 kWh of usable storage. A typical 5-horsepower well pump draws roughly 4,500 watts while running, so one Powerwall runs that pump for about three hours of continuous duty, or a full day of intermittent cycling. We size Kingsburg systems around your specific pump motor and run it off stored solar during the 5-8 p.m. peak window. Call (877) 550-6892 and we’ll run the numbers for your well.
Usually yes, but it requires a panel upgrade. PG&E’s interconnection rules for battery storage demand rapid shutdown and disconnect clearances that 100-amp panels built in the 1960s and 1970s can’t satisfy. We do the panel upgrade and battery install under one permit and one crew. In Kingsburg, that upgrade runs $2,800-$4,200 depending on your meter location and house configuration.
Yes, and this is one of the biggest opportunities most solar installers in the Valley miss. AG-4B agricultural rates on Kingsburg parcels with well infrastructure carry demand charges based on your peak draw. A solar-plus-battery setup with a smart controller can shift pump cycles to midday solar hours and discharge stored power during the demand window, cutting the demand charge component of your bill substantially. We configure the FranklinWH or Tesla system’s load control to match your irrigation schedule. Kingsburg sits in the heart of this dual-load market, and we build for it specifically.
For a 1970s ranch home with an existing solar array from the 2010s, the answer depends on your inverter. If you have a SolarEdge string inverter, a SolarEdge-compatible battery or a FranklinWH aPower system retrofits cleanly. If you have microinverters, Enphase IQ batteries tie in directly at the combiner. Our team rewired a 1978 ranch near the high school with an Enphase IQ battery after the original installer told the homeowner storage wasn’t possible. It is. Call us with your inverter brand and we’ll tell you what fits.
For Kingsburg homeowners with a battery fault, a tripped system, or a PG&E shutoff event, we’re usually on site within 24 hours. Scheduling and dispatch are coordinated from our Fresno, Central Valley office, and our crews serve Kingsburg locally. A live person answers our phone 24/7 at (877) 550-6892. If it’s late and your battery won’t hold, someone real picks up.
