AfterFast, Reliable Solar Battery Storage & Backup Across Clovis
When the power goes out in Clovis on a 106°F afternoon, a solar array without a battery is just expensive roof decoration. We get calls from homeowners in the 93611, 93612, 93613, and 93619 zip codes who sized their panels for net metering that no longer exists under PG&E’s NEM 3.0 rules. The fix is usually straightforward: add storage sized to cover the 4 to 9 p.m. window, then stop bleeding money into time-of-use rates. Our Solar Battery Storage & Backup team has been doing exactly this work in Clovis for years, and we quote system sizes off your actual utility bill, not a brochure. Call (877) 550-6892 and bring us a bill. We’ll bring you the math.
What most homeowners don’t realize until their first September true-up statement is that Clovis sits in a unique spot for battery economics. PG&E territory, yes, but the combination of triple-digit cooling weeks, agricultural irrigation loads on the grid, and NEM 3.0’s brutal 4 to 9 p.m. peak window means a battery here pays for itself faster than almost anywhere else in the Central Valley. A 20 to 30 kWh evening offset in Clovis will shave hundreds off a true-up bill that coastal homeowners never see.
Key Takeaways for Clovis Homeowners
- Battery storage under NEM 3.0 in Clovis typically pays back in 5 to 7 years when sized for evening peak usage, compared to 8 to 10 years in cooler coastal markets.
- Most Clovis battery failures we see are thermal: 105°F garage temps cause inverter derating, not battery cell failure.
- Same-day service is available across Clovis, including Harlan Ranch, Loma Vista, Buchanan Estates, and Old Town.
- A battery retrofit on a SolarEdge string system is doable without replacing your existing inverter in most Clovis homes.
- Free second opinion on any written estimate, and the price we quote on a Tuesday is the same price on Saturday.
Why Gus’s Solar Is Clovis’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis put his name on the truck in 2011, and he’s been answering his own phone ever since. When you call about battery storage in Clovis, you reach a live person, 24/7. Not a voicemail tree. Not a ticketing portal. Not a call center three states away. That matters when your Powerwall stops discharging an hour before an excessive heat warning hits the Harlan Ranch area.
Our crew are background-checked, uniformed, and they’re the same people who installed the system. We don’t hand work off to subs. If something’s not right, the 90-Day Done Right Promise applies and one call brings Gus back out. Our no-hassle upfront pricing is built off your actual PG&E bill with your actual export rates, not a generic estimate that assumes you live in a mild coastal city. And if you need two weeks to think about it, take two weeks. The price will be the same. If a salesman needs an answer tonight, the answer is no. That’s the L.O.C.A.L. code: Local roots, On time, Community first, Accountable, Loyal.
We serve Clovis as part of our broader Fresno and Central Valley coverage. We’re not a pop-up door-knocking crew that disappears after the permits clear. We have a published address, a license number, and an owner whose name is on the building. When a retrofit on an older 93612 subdivision home needs a subpanel upgrade, we tell you before we start, not after.
Our Solar Battery Storage & Backup Services in Clovis
Tesla Powerwall Installation
A Tesla Powerwall 3 install in Clovis typically runs $12,500 to $16,800 before incentives, including gateway, wiring, and interconnection paperwork. The Powerwall is the most common battery we install in Clovis homes because it handles the 4 to 9 p.m. PG&E window well and integrates cleanly with existing systems. We keep common replacement parts in our vans: contactors, CT clamps, and firmware update tools. If your Powerwall 2 is acting up in the 93619 zip code, we can usually fix it the same day with our Clovis Solar Panel Repair service, without a ticket that bounces around for two weeks.
Enphase IQ Battery Installation
The Enphase IQ Battery 5P runs $9,000 to $14,000 installed in Clovis, depending on whether you’re doing a single unit or a stack of two or three. These are ideal for Clovis homes with Enphase microinverters already on the roof, since they share the same monitoring app and rapid shutdown hardware. The 5P discharges at 3.84 kW continuous, so two units cover a typical Clovis 4-ton AC plus lights and refrigerator for the full evening peak window. We install and service Enphase batteries all over Clovis, including the newer builds east of Leonard Avenue.
Whole-Home Backup Power
Whole-home backup in Clovis typically means a 25 to 40 kWh stack, which runs $22,000 to $38,000 depending on your panel size and battery count. That’s two Powerwalls or three IQ Batteries, along with a smart load center or backup switch. In Clovis summers, we size systems to run a 4-ton or 5-ton air conditioner for at least four hours of a PG&E public safety power shutoff. The goal is staying cool through the 4 to 9 p.m. window without drawing from the grid and paying those peak rates.
Battery Retrofit for Existing Solar
Adding a battery to an existing Clovis solar array is the single most common project we do, because most systems here were installed before NEM 3.0 changed the economics in April 2023. Many of these systems also benefit from Solar Panel Maintenance & Monitoring - Clovis homeowners trust to keep peak performance. A retrofit typically runs $11,000 to $18,000 for a single battery with all wiring, breakers, and PG&E interconnection updates. Older Clovis subdivisions in 93612 frequently have front-yard main panels without a spare breaker slot, so a subpanel upgrade may add $1,200 to $2,400 to the total. We’ll tell you that before we start and it’ll be in your written quote.
Time-of-Use & NEM 3.0 Optimization
This is the service nobody asked for but everybody in Clovis needs. Under NEM 3.0, PG&E pays pennies for midday solar export and charges 50 to 65 cents per kWh from 4 to 9 p.m. That means the whole game is shifting your stored midday solar into the evening window. We program battery discharge schedules around PG&E’s actual Clovis rate schedule, not a generic California default. For a typical 93613 home with a 7 kW solar array, a 13.5 kWh Powerwall set to export during peak can cut annual true-up charges by $1,400 to $2,200. I quote the year-25 output, not the day-one brochure number.
Same-Day Battery Repair & Troubleshooting
We offer same-day service to Clovis because we know a battery failure on July 28th is not a “schedule it for next Thursday” situation. Common fixes we handle same-day include failed grid-charging contactors, CT clamp misreads, inverter thermal shutdowns, firmware hangs, and breaker trips on retrofitted subpanels. Hourly diagnostic rates start at $95, and we offer a free second opinion on any written estimate from another company.
Last July, our crew responded to a same-day call from a homeowner in the 93619 zip code near Harlan Ranch whose Tesla Powerwall 2 stopped discharging right before an excessive heat warning. We traced the fault to a failed grid-charging contactor and a degraded CT clamp on the main service panel, swapped the parts from our van stock, and ran a full rapid shutdown and interconnection self-test before the sun set, leaving the family with whole-home backup running by dinner.

Trusted Brands We Service in Clovis
We work with the industry’s leading equipment brands, including Panasonic, Canadian Solar, FranklinWH, Tesla, and Enphase. When a battery inverter fails in a Clovis garage during a heat wave, waiting a week for parts from a warehouse in Nevada isn’t an option, so we keep a rolling stock of common replacement components in our vans and at our Central Valley office. Whether you have a FranklinWH aPower system installed last year or a Panasonic EverVolt that’s been running since the NEM 2.0 days, our Clovis customers get fast turnaround on warranty claims and out-of-warranty repairs alike.
Common Solar Battery Storage & Backup Problems We See in Clovis Homes
- Thermal derating in garages: Clovis summers routinely push garages past 110°F by 3 p.m., and battery inverters start dialing back output to protect themselves. That means your “whole-home backup” can drop to half capacity right when the AC is working hardest. We install ventilation upgrades and, where possible, move batteries to cooler wall locations.
- NEM 3.0 undersizing: We regularly see Clovis customers who bought a 10 kWh battery thinking it would cover the evening peak, only to drain it by 5 p.m. during a triple-digit week. September true-up statements for those systems are ugly. Right-sizing means 20 to 30 kWh of usable storage for most all-electric Clovis homes.
- No spare breaker slot in older panels: Front-yard main panels in many 93612 subdivisions were installed in the 1990s and have no open slots for a battery breaker. That forces a subpanel upgrade before we can connect the battery, and it’s a cost homeowners don’t see coming from a generic online quote.
- CT clamp and contactor failures: The grid-charging contactor in a Powerwall or FranklinWH unit takes a beating from PG&E’s frequent voltage swings at the edge of Clovis’s agricultural irrigation load zone. Contactors and CT clamps are the two most common same-day repair items we see in the 93619 and 93613 areas.

FAQs - Solar Battery Storage & Backup in Clovis
Yes. You don’t need to replace your SolarEdge inverter to add a battery, because modern AC-coupled batteries like the Tesla Powerwall 3 and FranklinWH aPower work independently of your existing inverter. We run a separate battery inverter and wire it into a new breaker on your main panel or subpanel. In Clovis homes where the SolarEdge unit is still under warranty and performing fine, we leave it alone and add storage alongside it. The only exception we occasionally see is a home with a very old SolarEdge model that lacks the updated rapid shutdown firmware, and even then the battery install is unaffected. Call (877) 550-6892 and we’ll evaluate your existing system for free.
For most Clovis homes, 20 to 30 kWh of usable storage is the sweet spot to cover the 4 to 9 p.m. peak window during triple-digit summer weeks. A typical 4-ton AC with lights, fridge, and a pool pump draws 6 to 9 kWh per hour during peak, so a single 13.5 kWh Powerwall gets exhausted before 7 p.m. Two batteries or one larger FranklinWH system sized at 25 kWh or more generally gets you through the full window. We’ll calculate this off your actual PG&E bill and your actual cooling load, not a rule of thumb. Free estimates and no pressure. Bring me a bill, I’ll bring you the math.
Far and away, it’s a failed grid-charging contactor or degraded CT clamp on a Powerwall 2 or FranklinWH unit, often triggered by the frequent utility voltage swings from PG&E’s agricultural irrigation load in the eastern Central Valley. The symptom is simple: the battery stops charging from the grid or stops discharging during an outage. In Clovis summers, garages hitting 110°F also cause thermal derating that cuts output, and we see that almost as often. We keep contactors, CT clamps, and replacement firmware tools in our vans, so most of these are same-day fixes across the 93611 to 93619 zip codes.
Yes. Adding a second Powerwall to an existing NEM 2.0 system in Clovis is straightforward and typically runs $9,000 to $13,000 depending on whether a gateway upgrade is needed. Your NEM 2.0 export agreement stays intact, and the second battery gives you more stored midday solar to shift into the 4 to 9 p.m. window where PG&E now charges the highest rates in the Central Valley. For homes in the 93612 and 93613 areas, adding storage to a pre-NEM 3.0 system is one of the highest-return upgrades you can make right now. We’ll verify your interconnection agreement before quoting anything.
No. Battery installation doesn’t touch your roof. The battery mounts on a garage wall or exterior wall, and we run conduit from the battery to your main electrical panel or subpanel. There’s no roof penetration, no panel removal, and no inverter replacement unless your current inverter has failed on its own. In 93611 homes with a 200-amp main panel, we usually land the battery breaker directly on the main. In older 93612 homes with a 100-amp or 125-amp panel, a small subpanel upgrade may be needed, and we’ll quote that clearly before any work starts.
