Fast, Reliable Solar Battery Storage & Backup Across Highland
Solar battery storage in Highland, CA typically runs between $12,500 and $18,500 for a single Tesla Powerwall 3 or Enphase IQ Battery 5P installed and connected, before any service panel upgrade. Most Highland homes complete the job in one to two days once permits clear with San Bernardino County. If your house sits north of Base Line Street in the CAL FIRE High Fire Hazard Severity Zone, the battery sizing math changes before anyone touches a roof, and that’s exactly where our Solar Battery Storage & Backup team starts. Call us at (877) 550-6892 and we’ll walk your actual property, not a brochure estimate.
Why Gus’s Solar Is Highland’s Preferred Solar Battery Storage & Backup Company
We’ve been working Highland homes long enough to know that a 1970s tract house off Victoria Avenue doesn’t quote like a 1990s build near Greenspot Road, and neither should sound like a canned sales pitch. Gus Petrakis puts his name on every job and answers his own phone, which matters when a transfer switch trips at 9 p.m. and you need a human, not a ticket queue. Highland customers call us because the crew shows up background-checked and in uniform, the price on the written estimate is the price on the final invoice, and the owner is the one who comes back if anything isn’t right within 90 days. That’s the 90-Day Done Right Promise, in writing, on every battery job we do in the 92346 zip code.
We coordinate scheduling from our Inland Empire office, and crews reach most Highland neighborhoods within 24 to 48 hours for non-emergency calls. For grid-down situations, a live person answers at (877) 550-6892 around the clock. You won’t leave a voicemail and hope someone calls back after the weekend.
Our Solar Battery Storage & Backup Services in Highland
Tesla Powerwall Installation
A Tesla Powerwall 3 install in Highland runs $14,000 to $18,000 for the battery, Gateway 3, and labor, with homeowners north of Base Line Street often needing a 200-amp service panel upgrade added on. These homes, many built in the 80s and 90s, still carry original 100-amp panels that can’t safely feed the Powerwall’s internal transfer switch. We quote the panel work in the first number we hand you, not as a surprise change order after the permit comes back. Gus’s crew wires the battery into your existing panel, sets it up in the garage or on an exterior wall, and commissions it through the Tesla app before we leave.

Enphase IQ Battery Installation
Enphase IQ Battery 5P installations in Highland generally land between $12,500 and $16,000, and they’re a strong fit for homes that already run Enphase microinverters on the roof. The 5P pairs naturally with existing Enphase arrays from the 2010s, which we see regularly in Highland’s newer subdivisions east of Weaver Street. Because the system uses microinverter-level communication, winter morning shading from the San Bernardino Mountain ridge line doesn’t kill the whole string the way it does on older central-inverter systems. We size the battery against what your array actually recharges during daylight hours, not what it produced ten years ago.

Whole-Home Backup Power
Whole-home backup in Highland means running your AC through a summer evening when temperatures above 105°F push SCE time-of-use rates to their peak, and the grid decides to sag. A two-battery configuration, either dual Powerwalls or dual IQ Battery 5Ps, typically runs $24,000 to $34,000 installed and covers the high-draw loads most Highland households actually run: central air, refrigerator, well pump if you have one, lights, and the garage door. For homes near the canyon mouths feeding down from the San Bernardino National Forest, where outages can follow wind events, we design the backup list with the homeowner room by room. No generic “essential loads” checkbox.

Battery Retrofit for Existing Solar
This is the biggest request we get from Highland homeowners with solar arrays installed between 2005 and 2018. A battery retrofit pairs new storage with your existing panels, and in Highland the retrofit conversation has to start with two local realities. First, fire-zone setbacks north of Base Line Street often shrank the original array by 2 kW or more compared to what the national installer promised. Second, many of those systems still run original string inverters that a modern battery platform won’t speak to without an inverter swap. A full retrofit, including inverter replacement and battery, runs $16,000 to $25,000 in Highland depending on whether your existing racking and wiring can be reused. We pulled a Tesla Powerwall retrofit for a homeowner off Greenspot Road whose existing 6 kW system was squeezed by HFHSZ setbacks on a 1990s composition-shingle roof. Their 100-amp service panel couldn’t safely handle the Powerwall’s transfer switch, so we upgraded to 200 amps, landed the battery in the garage, and now their AC keeps running through SCE’s summer peak without feeding the older 4 kW array into an undersized inverter.

Common Solar Battery Storage & Backup Problems We See in Highland Homes
- Original 100-amp panels can’t carry a Powerwall transfer switch. Homes built across Highland’s 1970s to 1990s suburban tract boom often still run their original 100-amp service. Grid outages with a battery attached to an undersized panel cause repeated breaker trips, exactly when you need the backup working.
- Battery retrofits on 1980s and 1990s tile roofs reveal degraded underlayment. Conduit penetrations through older tile often expose cracked or crumbling underlayment underneath. We flag it during the site survey, but unpermitted repair there can stall interconnection approval for weeks.
- Winter morning ridge-line shading limits recharge from east-facing arrays. Homes in Highland’s northern tier, near the canyon mouths feeding down from the San Bernardino National Forest, often have a legacy east-facing array that barely recharges a battery during short winter days. Backup capacity ends up too low for after-sunset AC loads if the system wasn’t sized for that shade.
- NEM 3.0 rate structures leave old solar owners exporting power for pennies. Any Highland homeowner who installed solar under NEM 2.0 and hasn’t added storage is giving SCE cheap daytime exports and paying peak evening rates. A battery changes that math, especially with summer AC loads driving the consumption side.

FAQs - Solar Battery Storage & Backup in Highland
Your battery goes inside or against an exterior wall with no additional fire-zone restrictions, but the solar array feeding it is what’s constrained. HFHSZ designation north of Base Line Street forces mandatory panel setbacks from roof edges, which shrinks installable array size compared to lower valley cities like Fontana or Rialto. So battery sizing in Highland often starts with how much backup the remaining panels can actually recharge during summer heat waves. A parcel with a 6 kW fire-zone-compliant array charges a battery differently than an 8 kW array in a valley-floor tract. Call (877) 550-6892 and we’ll pull your parcel’s FHSZ designation before we quote anything.
Most 100-amp panels, common on Highland homes built through the 1990s, cannot safely accommodate a Powerwall 3’s transfer switch without a 200-amp upgrade. The panel upgrade adds $3,000 to $4,500 to the job in Highland. During our site survey we confirm your panel rating in the first visit, so the upgrade is in your first written number, not a change order after the permit comes back from San Bernardino County. Call (877) 550-6892 for an exact assessment.
Yes, east-facing legacy arrays in Highland’s northern neighborhoods often lose an hour or more of morning production to ridge-line shading in December and January. An IQ Battery paired with microinverters handles partial shade far better than a central string inverter, but total daily recharge still drops. We size winter backup capacity against actual winter production numbers from your monitoring history, not summer peaks. Call (877) 550-6892 and bring us a year of production data if you have it.
Under NEM 3.0, SCE pays far less for daytime solar exports, so the financial case for a battery in Highland is no longer about export credits. It’s about holding your own daytime generation to run the AC when time-of-use rates peak from 4 p.m. to 9 p.m., which in Highland summer months is exactly when indoor temperatures push past 90 without cooling. A properly sized battery shifts your heavy evening load off the grid and onto stored solar. Call (877) 550-6892 and we’ll model your bill under NEM 3.0 with and without storage.
A Tesla Powerwall 3 with the inverter integrated handles the retrofit cleanly, typically $16,000 to $25,000 installed in Highland with panel upgrade included. The original central inverter comes out, the Powerwall’s built-in inverter takes over, and you avoid the cost of a separate string inverter replacement. If the roof array is also nearing end of life, we’ll tell you straight whether replacing panels and adding storage together is the better spend than retrofitting aging hardware. Call (877) 550-6892 for a written quote after we walk the roof.
