Call (877) 550-6892

Gus Petrakis put his name on this company in 2011, and he still answers his own phone. Our Solar Battery Storage & Backup team works Ennis the way it should be worked: we show up when we say we will, we quote real numbers off your actual electric bill, and we tell you to take two weeks before you sign anything.

Why Gus’s Solar Is Ennis’s Preferred Solar Battery Storage & Backup Company

Ennis homeowners have been burned by out-of-state outfits that quote one number on the phone and another at the door. That does not happen with us. Gus publishes his address, his license number, and his cell number. When you call (877) 550-6892, you get a person, not a queued recording. Local roots, on time, community first, accountable, loyal. Those are not bumper stickers to us. They’re the L.O.C.A.L. values Gus built the shop on.

We have worked on homes radiating out from the historic downtown: the 1950s ranch streets near Baylor Scott & White Medical Center, the 1970s subdivisions off Kaufman Street, the newer construction pushing west toward I-45. Our crews have retrofitted batteries onto original 100-amp panels near the Ennis Railroad & Cultural Heritage Museum and threaded conduit through carports off Ennis Avenue. We know which neighborhoods still have alley-loaded electrical service and which ones got panel upgrades in the last decade.

Response time to Ennis matters when a hail system rolls through in March and your freezer’s full of beef. We send crews out of our Dallas-Fort Worth office and we’re generally on site in Ennis the same day for emergencies. Not “sometime next week.” Same day.

Every job carries the 90-Day Done Right Promise. If it isn’t right, Gus comes back and makes it right. In writing.

Our Solar Battery Storage & Backup Services in Ennis

Tesla Powerwall Installation

A Tesla Powerwall 3 installed in Ennis runs $13,000-$17,500 depending on your panel situation. On the 75119 and 75120 side of town, where homes carry 1950s-1980s panels, the first question is almost always whether your 100-amp service can handle the load. Often it can’t, and we fold the upgrade into the same quote so you’re never surprised at permit time. Powerwall handles Ennis’s spring outages well, and the integrated inverter means fewer boxes on your wall.

Enphase IQ Battery Installation

Enphase IQ Battery 5P systems typically run $12,000-$16,000 installed in Ennis. We like these for smaller ranch homes because the modular design lets you start with one battery and add capacity later without rewiring the whole wall. The 5P pairs naturally with Enphase microinverters already on many local roofs, and it’s quick-disconnect compliant for fire safety, which matters when your battery sits close to the house on a tight lot near downtown.

Whole-Home Backup Power

If you want to keep the air conditioner running during a March-June severe-weather outage, that’s a whole-home backup, and in Ennis that means $18,000-$25,000 for a multi-battery stack with a smart load panel. We calculate your actual loads off your utility bill. Bring us a bill, we’ll bring you the math. Most Ennis customers two batteries are enough for refrigeration, lights, a well pump, and the microwave, but not the 4-ton AC. We tell you that up front, not after you’ve signed.

Battery Retrofit for Existing Solar

The majority of our Ennis work right now is retrofitting batteries onto existing solar arrays that were installed five to ten years ago without storage. If your system was permitted under Ellis County’s previous interconnection rules and is in good shape, adding a battery is doable for $10,500-$14,500. We check your inverter, your rapid-shutdown compliance, and your panel capacity before we quote anything. No pressure. Take two weeks. The price will be the same.

Trusted Brands We Service in Ennis

We install and service batteries from Tesla, Enphase, FranklinWH, and SolarEdge, and we pair them with panel brands like Qcells, REC, and Panasonic. We keep common Enphase and Tesla parts stocked at the shop, which means when your Ennis system throws a fault code, we’re not waiting on a freight shipment from California. For Ennis homeowners with existing REC or Qcells arrays, retrofitting with Enphase or FranklinWH storage is straightforward and keeps your monitoring under one app. We don’t push one brand. We push the one your existing system supports best.

Common Solar Battery Storage & Backup Problems We See in Ennis Homes

• Heaving pads on gumbo clay. Ellis County’s black-clay soils swell when wet and crack when dry. A battery pad poured to standard depth will heave within two wet-dry cycles, cracking conduit and pulling disconnects out of alignment. We pour deeper footings on every Ennis ground-mounted battery, and we’ve repaired six pads this year that were poured by installers who didn’t know the soil.
• 100-amp service panels blocking interconnection. The 1950s-1980s ranch stock that dominates Ennis’s residential streets often still carries the original 100-amp panel. Oncor will not approve a battery interconnection on an undersized panel. We include the panel upgrade cost in our quote up front so it doesn’t ambush you at permit stage.
• Alley-access and narrow-side-yard conduit issues. Older homes near downtown Ennis have tight alley clearances and shared utility poles. A sloppy install can block a neighbor’s access and trigger a code visit. We route conduit through existing carports and garages wherever possible, and we check clearance before we mount anything.
• Batteries configured without time-of-use optimization. We see Ennis systems installed by national crews that never programmed the battery to discharge during peak-rate windows. The homeowner draws grid power at 4-7 PM, pays peak rates, and sees no true-up reduction. We fix that. Your battery should earn its keep, not sit charged while you buy expensive kilowatts.

What Makes Ennis Different for Battery Backup

Ennis sits on the same flat blackland prairie hail corridor that has pushed local insurers to mandate Class 4 impact-rated roofing across Ellis County. Hail here is not rare. It’s structural. Yet most battery backup proposals we review still skip impact-resistant enclosure specs. That’s backwards. If your roof needs Class 4 shingles to satisfy your carrier, your $12,000 battery sitting on a poured pad in the backyard needs the same respect. We spec impact-rated enclosures and position batteries on the lee side of the home wherever possible, away from prevailing southwest storm tracks. That’s an Ennis-specific design decision, not a generic brochure line.

The open prairie gives Ennis excellent solar exposure. Minimal tree cover, no horizon shading, strong annual sun hours. That’s the good news. The bad news is that same open terrain lets spring straight-line winds hammer equipment with debris. In the 75119 and 75120 zip codes, we’ve replaced crushed conduit and cracked enclosures after April wind events. Our installs account for that: heavier gauge conduit, stainless hardware, and batteries anchored to pads with footings cut for gumbo clay’s wet-dry cycle.

And that gumbo soil deserves its own word. The expansive clay under Ennis homes is the same soil that causes chronic foundation movement on the older ranch stock. A ground-mounted battery rack anchored for sandy loam will shift or heave within a season or two. Our crew retrofitted an Enphase IQ Battery 5P onto a 1980s ranch home near the historic downtown, where the original 100-amp panel had to be upgraded before the interconnection application could even be submitted. We routed conduit through the existing carport to avoid alley-access clearance issues, and set the battery on a poured concrete pad with deep footings to handle the gumbo clay’s wet-dry heave. The homeowner now runs essential loads through rapid shutdown-compliant microinverters during spring storm outages without losing refrigeration.

That job took two days. The quote was the same on the last day as it was on the first. If a salesman needs an answer tonight, the answer is no.
