AfterFast, Reliable Solar Battery Storage & Backup Across Converse
Solar battery backup in Converse runs $9,500 to $18,500 installed, depending on whether you’re adding a single Tesla Powerwall 3 or building a whole-home system with multiple Enphase 5P batteries. Most Converse homeowners we work with want one thing: power that stays on when CPS Energy’s grid wobbles during a July thunderstorm or a February freeze. We’ve been installing and retrofitting battery systems in Converse’s 78109 neighborhoods since long before battery storage became a buzzword. Call (877) 550-6892 and we’ll give you straight numbers off your actual utility bill, not a brochure estimate.
Why Gus’s Solar Is Converse’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011, and his name is on the truck, the building, and every quote we hand a Converse homeowner. We’re not a pop-up sales crew running a door-knocking blitz through Northampton or Meadowbrook. We’re the company your neighbor calls when a battery system installed by an out-of-state outfit stops talking to their inverter. Our Solar Battery Storage & Backup team has retrofitted batteries onto existing solar arrays all over Converse, from the subdivisions along FM 1516 to the streets off Toepperwein Road.
Converse homeowners have told us the same thing for years: they want a face they’ll see again at H-E-B, not a 1-800 number that routes to a call center in another state. Gus answers his own phone. If something goes wrong, you call, a live person picks up, and Gus’s own background-checked crew comes out. We don’t hand work off to subs. The uniformed technician on your Converse roof or in your garage is on Gus’s payroll, not a third party’s.
We’ve worked on enough Converse homes to know the difference between a Northampton brick-veneer ranch and a newer Lennar build off Kitty Hawk Road. We know which subdivisions have architectural review committees that will flag a street-facing battery disconnect, and which ones don’t care what you put on the back slope. That local knowledge keeps you out of HOA trouble and keeps your project moving. No trip charge inside Bexar County, free estimates, and the 90-Day Done Right Promise in writing on every job. If it’s not right, one call brings Gus back.
Our Solar Battery Storage & Backup Services in Converse
Battery Retrofit for Existing Solar
Most Converse homes with solar already have panels on the roof and an inverter on the wall. What they don’t have is storage. We retrofit batteries onto existing systems all the time, including older SolarEdge and Enphase setups that installers said couldn’t be upgraded. If your panels are five or ten years old and still producing, we can almost always add a battery. In the Northampton subdivision just off FM 1516, our crew retrofitted a Tesla Powerwall 3 to a 2012-built brick-veneer home. The homeowner’s Enphase microinverters were already showing afternoon production drops from west-facing roof surfaces hitting 150°F in July, and the HOA had previously flagged a neighbor’s street-facing panel array, so we ran the new battery circuit through the garage subpanel, kept all conduit inside the interior wall chase, and filed the ARB modification using the community’s pre-approved color match for the exterior disconnect. That’s the kind of work you only get from a crew that has actually done it in Converse, not one reading a spec sheet.
Whole-Home Backup Power
Whole-home backup in Converse means sizing a battery system to carry your air conditioner through a Bexar County summer afternoon. That’s a different conversation than backup in Michigan. A single Powerwall 3 holds 13.5 kWh, which might run lights, fridge, and a window unit but won’t carry a 4-ton AC through a 100°F afternoon without careful load management. Two or three batteries start to make true whole-home coverage realistic. We model the math honestly using your actual CPS Energy usage history, not a generic kilowatt-hour guess. If the numbers don’t work, we’ll tell you. Gus would rather lose a sale than sell you a battery that browns out the first time your compressor kicks on.
Time-of-Use & NEM 3.0 Optimization
CPS Energy is not NEM 3.0 territory, but Converse homeowners on time-of-use rate plans still need their batteries programmed correctly to avoid pulling grid power during peak afternoon pricing. We configure battery discharge curves to match your actual rate schedule. Many Converse homes we service have batteries that were never properly commissioned, so they sit fully charged while the homeowner pulls expensive grid electricity at 4 p.m. We fix that. A properly optimized battery in Converse shifts your stored solar into the evening and early morning when the grid is priciest. That’s where the real bill savings show up, not in the day-one marketing brochure.
Battery Replacement & Expansion
Batteries degrade. A battery installed in Converse in 2018 is now seven years old and has been baking in a Texas garage where summer temperatures routinely hit 110°F. We replace aging batteries, expand existing systems with additional units, and rebalance old battery stacks so they actually deliver their rated capacity. If your FranklinWH aGate or first-generation Tesla Powerwall is underperforming, we can diagnose it and give you an honest replacement number. We keep parts for the major brands stocked locally, which means faster turnaround for Converse customers than waiting on a shipment from a warehouse in California.

Common Solar Battery Storage & Backup Problems We See in Converse Homes
We’ve been inside enough Converse garages and attics to know the failure patterns. Here’s what we see most often:
- Battery sized wrong for the AC load. A salesperson quotes a single battery for “whole-home backup” without checking the compressor’s LRA draw. The first hot afternoon, the battery trips and the house goes dark. We size systems using your actual AC specs and load profile, not a square-footage guess.
- HOA architectural review skipped. Converse has multiple planned communities with active ARBs. A battery installed on a street-facing wall or with the wrong disconnect color triggers a violation letter and sometimes a forced move. We know which subdivisions require pre-approval and file the paperwork correctly the first time.
- Battery installed on a failing roof. Homes built in the early-to-mid 1990s in Converse are hitting the 25-to-30-year roof replacement window. Some installers will mount panels and run conduit right over a roof that needs replacement next year. Then the roofer won’t touch it, and the roof warranty is void. We flag this early and coordinate a re-roof or panel removal before the battery work happens.
- CPS Energy interconnection delay ignored. CPS is the nation’s largest municipally-owned utility, and its Distributed Generation program has a real application backlog. Some Converse homeowners buy a battery expecting immediate grid export, then wait months for approval. We set realistic timelines from the start and build the battery’s value around backup and load shifting, not uncertain export credits.
Pricing for Solar Battery Storage & Backup in Converse, TX
A single Tesla Powerwall 3 with installation in Converse typically runs $9,500 to $12,500 before incentives. Adding a second battery pushes the total to $18,000 to $24,000.

FranklinWH aGate systems in Converse run $12,000 to $16,000 installed. What changes the number: whether your existing panel needs a subpanel upgrade, how far the battery sits from your main breaker, and whether we’re retrofitting onto existing solar or starting fresh. Every quote we give Converse homeowners is built off their actual CPS Energy bill and their actual roof, not a standard price sheet. Call (877) 550-6892 for a free estimate. Take two weeks.

FAQs - Solar Battery Storage & Backup in Converse
It depends on your subdivision’s architectural guidelines, but in most Converse planned communities with an active ARB, yes, you’ll need approval for any exterior-mounted equipment like a battery cabinet or disconnect, and approval typically takes 2 to 6 weeks depending on the committee’s meeting schedule. We handle the filing, use the community’s pre-approved color matches, and design the placement to avoid street-facing slopes wherever possible. Call (877) 550-6892 and we can pull your subdivision’s specific requirements before you spend a dollar.
CPS Energy’s Distributed Generation program has a real application backlog, and a battery system that exports to the grid won’t be approved overnight; the queue time can range from a few weeks to several months depending on application volume. That’s why we don’t sell Converse homeowners on export credit payback. We design the battery’s value around backup power and load shifting, which work the day the system is installed, regardless of where you sit in CPS’s queue. Call (877) 550-6892 and we’ll check your address’s current CPS status for free.
Yes, but not through a PACE lien. VA loans prohibit PACE liens, which is one of the most common financing paths national solar companies push. So we structure Converse battery proposals around cash, traditional home equity, or unsecured solar loans that don’t attach to the property title. If a salesperson tries to put a PACE lien on your Converse home and you’re on a VA mortgage, walk away. Call (877) 550-6892 and Gus will walk you through the financing options that actually work for a VA-backed mortgage.
We retrofit batteries onto existing systems from other installers all the time, and if your Converse roof is 25 or 30 years old, we’ll flag that before we add any battery load or conduit work. A battery mounted on a failing roof creates a warranty mess and a future re-roof problem. We’ll give you options: re-roof first, move panels, or phase the work. The original installer doesn’t matter to us. We have a free second opinion on any written estimate you’ve received, and we’ll tell you honestly if your existing system can support a battery without major rewiring.
A single battery usually will not cover a 4-ton or 5-ton central AC through a full Converse summer afternoon of 100°F plus heat, but two or three batteries sized correctly can carry the compressor with smart load management. The honest answer is that most Converse homes need at least two Powerwall 3s or three Enphase 5Ps for true whole-home comfort during a July outage. We model your actual compressor draw and your actual CPS Energy usage so you know exactly what a system will and won’t carry before you sign. Call (877) 550-6892 and bring us a bill. We’ll bring you the math.
