PES Supply Q3 2026: New Products, Brands, and Catalog Updates

PES Supply Editorial Team · ~15 min read · Quarterly catalog brief for trade customers

Quarterly updates risk reading like press releases, so we'll start with what actually changed for the people who buy from us: the catalog crossed 50,000 active SKUs and 169 authorized brands this quarter, the deepest additions landed in battery storage and hybrid inverters, and delivery is holding at 7–10 business days despite the tariff noise that scrambled half the industry's supply chains this spring. The rest of this brief is the detail behind those three facts — what's new by category, which brand relationships expanded, and how to use the expanded catalog to shorten your own procurement cycle.

It's worth saying plainly why we keep publishing these: a distributor catalog only has value if the trade knows what's in it. Every quarter we watch installers source around us for products we already stock, simply because the catalog outgrew their memory of it. These briefs are the fix. Skim them, forward them to whoever does your purchasing, and treat the tables as a spec'ing shortcut — every example SKU linked below is live, in the catalog, and quotable today. If something you need isn't listed, that absence is the exception worth a phone call, not the rule.

One framing note before the categories: we write these updates for installers and contractors, not for shareholders. That means we'll be specific about what the additions are good for, blunt about compatibility traps, and honest about where lead times still stretch. If you want the two-minute version, scan the tables; if you're speccing a Q4 project, read the category sections.

The authorized-brand count matters more than it might look. Every brand in the catalog is a manufacturer relationship with real warranty backing — not gray-market inventory of unknown provenance. When your AHJ or your customer's insurance company asks for documentation, authorized-channel paper is the difference between a two-minute email and a two-week problem.

Catalog expansion at PES isn't a purchasing department chasing a SKU count. Each addition follows the same path: installer requests and quote-gap analysis identify what we're being asked for and can't supply; our team vets the manufacturer on listing status (UL/ETL documentation, warranty terms, US service presence); a pilot order tests packaging, freight damage rates, and datasheet accuracy; only then does the line go live for quotes. The process is slower than buying whatever's cheap on the spot market, and it's the reason the warranty-claim experience through an authorized channel stays boring.

The Q3 battery expansion followed exactly that arc — installer demand for retrofit storage pulled the category, listing review narrowed the candidate list, and the lines that made the catalog are the ones whose documentation survived contact with a real permit package. When you see a brand in our catalog, it has already passed the paperwork test that your AHJ will run on it.

Buyers deserve the honest macro picture, because it shapes quoting strategy for the rest of 2026. Module prices rose 2–5% in the first half of the year on AD/CVD determinations and shifted supply origins; aluminum tariffs at 50% pushed racking and frame costs up; and the dollar moved around enough to make import pricing jumpy week to week. Against that, domestic module manufacturing capacity keeps expanding and balance-of-system costs have been stable-to-down. The net effect for a contractor: equipment pricing is more volatile line-by-line than it's been since 2022, which rewards two habits — quoting with expiration dates you actually honor, and locking pricing at contract signing rather than at install scheduling. We hold quoted pricing for the window stated on the quote, and the expanded catalog means an equivalent alternate exists when a line moves mid-project. In a volatile quarter, that alternate column isn't a courtesy — it's schedule insurance.

The panel category grew across every major class this quarter. High-efficiency residential modules in the 400W+ range now include multiple N-type TOPCon options with better temperature coefficients than the PERC panels they replace — worth real money in hot climates, as our seasonal production guide quantifies. Commercial-format modules expanded for rooftop and ground-mount work, and the bifacial selection deepened for flat-roof and ground-mount designs chasing rear-side gain.

Brand depth sits alongside the SKU count: Qcells, JA Solar, Trina, REC, and Mission Solar all ship from the catalog with current datasheets. One buying note: with module prices up 2–5% this year on tariff-driven supply shifts, the savings between brands have compressed — this is a good quarter to compare apples across manufacturers on the same BOM rather than assuming your usual brand is cheapest.

The inverter category saw its most meaningful expansion in hybrids — units that blend grid, solar, battery, and generator inputs in one box. The driver is no mystery: storage attach rates keep climbing, and customers increasingly want outage protection without a second box on the wall.

A spec'ing note from the counter: the hybrid class splits into AC-coupled retrofit-friendly units and DC-coupled new-build units, and ordering the wrong architecture for an existing system is the most common inverter return we process. If the customer already has a grid-tie inverter under warranty, retrofit batteries like the Enphase IQ 5P or an AC-coupled cabinet from the ESS category usually beat a rip-and-replace. If it's new construction, a native hybrid wins on cost and simplicity almost every time.

Rather than listing 169 logos, here's where the brand bench is deepest heading into Q4 — the lines with the broadest SKU coverage and the shortest path to a complete BOM:

Deep benches matter for a boring reason: alternates. When one line goes allocation-limited — and in this tariff environment, some line always is — a deep bench means your project pivots to a spec-equivalent unit instead of waiting six weeks. That's the practical value of a 169-brand catalog, and it's why we keep investing in breadth rather than exclusivity deals that would narrow it.

The delivery promise is worth unpacking because it's the line item customers are most skeptical about. Small equipment — breakers, controllers, disconnects, wire — ships parcel and typically beats the window. Palletized freight — panels, batteries, inverters — ships LTL with liftgate service, and the 7–10 day window includes the freight carrier's scheduling reality, not just our warehouse clock. Two practices keep freight drama rare: we photograph pallet condition at dispatch, and we tell every customer to inspect and note damage at delivery before signing. A damage note on the delivery receipt turns a freight claim from a fight into a formality. Refusing to inspect at delivery is the single most expensive habit in solar freight — five minutes with a camera phone protects a five-figure order.

Will-call and scheduled freight for commercial jobs are available; mention the site constraints (liftgate, limited access, delivery windows) in the quote request and the logistics plan gets built into the price instead of appearing as an accessorial charge later.

Storage is where the catalog invested hardest. The batteries and energy storage category now spans three clear tiers, and knowing which tier a job belongs to saves real money:

The compatibility warning from the original version of this update stands, and Q3's expansion makes it more important, not less: more brands means more combinations that don't talk to each other. Closed-loop battery communication is brand-paired — an EG4 rack behind a Sol-Ark needs verified open-loop settings, and not every combination is sanctioned. When you send us a BOM, compatibility verification is part of the quote, not an upsell. The 20/80 battery rule and sizing guide cover the operating discipline once the hardware lands.

Modules and inverters get the headlines; racking and BOS get the red tags. Q3 additions in the unsexy categories: expanded rail profiles and clamp coverage, more flat-roof ballasted options, additional standing-seam clamps for penetration-free metal-roof attachment, and deeper ground-mount structure inventory including the PES 24-panel Sinclair Sky Rack commercial kit. On the electrical side, the electrical supplies category added PV-rated disconnects, PV SPDs (mandatory under NEC 2023+ — see the NEC 2026 rundown), listed 10 AWG PV wire, and the breaker coverage to match the expanded inverter line.

Generators round out the resilience side of the catalog — the standby generator category now pairs cleanly with the storage additions, from the Cummins RS20ACE 20kW to Generac Guardian-series units like the 26kW with 200A ATS. Solar-plus-storage-plus-generator is no longer an exotic request; it's a standard quote line, and stocking all three under one PO is the entire point of the catalog buildout.

The generator category deserves its own paragraph this quarter because the buying pattern changed. Contractors are no longer quoting generators as an either/or against batteries — they're quoting both, with the battery carrying overnight and short outages and the generator carrying multi-day storms. The transfer equipment that makes this safe is the other growth line: transfer switches and interconnection hardware, including service-entrance-rated ATS units, expanded to cover the hybrid-plus-generator configurations that used to require custom engineering. If you're new to pairing the two, the whole-home generator sizing guide and the 26kW generator guide cover the load math, and the 22kW primer handles the most-quoted residential size.

Not every customer is a contractor, and Q3 expanded the pre-engineered end of the catalog accordingly: DIY solar kits, complete packaged systems, and grid-tied system bundles that ship with matched components and documentation. The engineering value of a kit is real — string lengths, conductor sizes, and compatibility are pre-solved — but we tell DIY buyers the same thing every time: the kit solves the equipment design, not the permitting. The permitting guide is the companion read, and a licensed electrician's involvement is still the right answer for anything that touches a panelboard.

Three practical takeaways for contractors planning Q4 work:

• Consolidate POs. With panels, inverters, storage, racking, BOS, and generators in one catalog, kitting a whole job on one purchase order cuts freight, receiving trips, and invoice reconciliation. We've watched shops save a full admin day per project just by stopping the five-vendor procurement habit — and that's before counting the warranty simplification.
• Send complete BOMs. A quote request with panel model, inverter model, battery count, racking type, and footage comes back same-day to 48 hours. A request that says "need stuff for a 10kW job" starts a phone tag chain. The catalog is deep enough now that a complete BOM almost never hits a gap — and when it does, we flag it on the quote rather than letting you discover it at the install.
• Ask about alternates. With 169 brands, there's usually a spec-equivalent alternate when your first choice is backordered or tariff-priced. The alternate-suggestion step is standard in our quoting — say yes to it in the notes field and we'll include it automatically.

For the policy backdrop shaping Q4 pricing — tariffs, domestic manufacturing, and the NEC transition — the 2025 H1 industry retrospective remains the piece to read, and its lessons (diversify module sourcing, budget for aluminum tariff exposure, lock quotes early) all still apply.

To make the consolidation point concrete, here's a real-shape residential storage retrofit quoted this quarter: 16 × 450W-class modules, one 12 kW hybrid inverter, four rack batteries, roof racking and flashing, 250 feet of PV wire, disconnects, breakers, and a service-entrance transfer switch. Under the old five-vendor habit, that's five quotes, five freight schedules, five warranty contacts, and a week of coordination. As a single PES order it's one quote (returned next day), one freight plan, one delivery window, and one invoice — with the compatibility check (battery-to-inverter closed loop, breaker-to-panel listing) done inside the quote instead of discovered on the roof.

The part contractors underestimate is the warranty side. When the whole BOM comes through one authorized channel, a failure in year three is one phone call with one order number. Split-sourced jobs turn every warranty claim into a forensic exercise in who sold what. Consolidation isn't just cheaper on freight — it's cheaper on every future service event.

The pipeline for the fourth quarter includes further storage platforms, next-generation hybrid inverters, and deeper commercial BOS inventory. The direction won't change: broader authorized-brand coverage, complete-BOM kitting, and 7–10 business day delivery. If there's a product line you want us to carry, the request channel is the contact page — the Q3 battery expansion started exactly that way, with three contractors asking the same question in the same month. Ask — it genuinely moves the catalog.

A final operational note for the people who actually process the orders. Every PES quote breaks out line-item pricing, lead time per line, freight classification, and warranty documentation links. Three fields deserve attention before you cut the PO: the lead-time column (mixed orders arrive on the longest line's schedule unless you ask us to split-ship), the freight class (liftgate vs. dock delivery changes the site requirement), and the alternates column (accepting a listed alternate up front prevents a mid-project substitution conversation). Shops that read those three fields stop having receiving-dock surprises. Shops that don't, call us — which also works, but the first way is faster.

That is really the whole theme of this quarter's update: the catalog got broader, the stocking got deeper, and the logistics got more predictable, so the contractors who plan a week ahead spend less of their margin on surprises than the ones buying day-of. Everything we added in Q3 exists to make the planned purchase easier than the emergency one.

How many SKUs does PES Supply carry?

The catalog crossed 50,000 active SKUs from 169 authorized brands in Q3 2026, covering solar panels, inverters, battery storage, charge controllers, racking, generators, and electrical BOS for residential, commercial, and off-grid projects.

What is the delivery time on orders?

Standard delivery runs 7–10 business days across the catalog. Large commercial orders and freight-heavy items may run longer; your quote states the timeline for each line item.

What was added in Q3 2026?

The deepest additions landed in battery storage (rack batteries, integrated ESS, and portable lithium), hybrid inverters in the 12–15 kW class, high-efficiency N-type TOPCon and bifacial panels, expanded racking and flat-roof options, and NEC-compliant BOS including PV SPDs and listed disconnects.

Can PES Supply verify cross-brand compatibility?

Yes — compatibility verification is built into the quoting process. Send a complete bill of materials and the team confirms battery-inverter communication pairs, listing requirements, and spec-equivalent alternates for backordered items.

Does PES Supply stock generators as well as solar?

Yes. The catalog includes standby and portable generators from Cummins, Generac, and Champion alongside the solar and storage lines, so resilience projects can be kitted on a single purchase order.

How do I request a quote for a complete system?

Use the Request a Quote page and include your full BOM — panel model, inverter model, battery count, racking type, and conductor footage. Complete BOMs come back same-day to 48 hours with trade pricing and full OEM warranty documentation.
