Powerwall 3 Combo Packs — Deprecation Notice

Aurora now supports adding a Tesla Powerwall 3 and its expansion units as separate components. Because of this, the bundled "combo pack" components — such as Tesla Powerwall 3 + 1 Expansion Unit, + 2 Expansion Units, and + 3 Expansion Units — are being retired.

Combo pack components remain available through early September 2026. After that they will be marked deprecated: existing designs that already use them will continue to work, but combo packs will no longer appear in component dropdowns for new designs.

If your tenant has the updated storage experience enabled, stop using combo packs now. Use the base battery plus expansion units instead. You don't have to wait for the deprecation date — admins can turn combo packs off in their own catalog whenever they're ready.

⚠️ If you manage partner or dealer organizations, this requires action from you.

Components are assigned per partner, and your partners cannot enable components for themselves. When combo packs are deprecated, any partner organization you haven't enabled Powerwall 3 and Powerwall 3 Expansion for will lose the ability to quote Powerwall 3 entirely — with no way to fix it on their end.

Plan to update the component assignments and pricing for every partner organization in your account, not just your tenant-level catalog. See For admins: setting up your catalog below.

What combo packs are and why they existed

A "combo pack" is a single component in the Aurora component database that represents a fixed bundle of Powerwall 3 hardware — packaged as one selectable item.

Combo packs come in two shapes:

• One base unit plus expansion units — for example, "Powerwall 3 + 2 Expansion Units"
• Multiple base units, with or without expansion units — for example, "(2) Powerwall 3" or "(2) Powerwall 3 + 2 Expansion Units"

Combo packs existed as a workaround. Aurora previously allowed only one battery type per design, and a Powerwall 3 base unit and an expansion unit are two different battery types. To quote a Powerwall 3 system at the correct capacity and price, all of the hardware had to be pre-bundled into a single component.

This workaround had real costs:

• Component sprawl. Every valid combination needed its own component. A single tenant could easily have four or more Powerwall 3 entries in their catalog, plus tenant-scoped custom variants.
• Confusing dropdowns. Multiple near-identical "Powerwall 3" entries appeared in battery and inverter lists, with no easy way to tell them apart.
• Rigid configurations. Changing the number of expansion units meant swapping to an entirely different component rather than adjusting a quantity.
• Pricing complexity. Each combination needed its own price maintained in the component database.

What's changing

Aurora now models a Powerwall 3 the way it works in the real world: a base unit, plus up to three expansion units attached to it. 

You don't set the number of base units directly in Sales Mode. Pick a Powerwall 3 base unit and AutoStringer adds more base units if the system needs them. Adjust expansion units from there. In Design Mode, you can also add base units individually.

For admins: setting up your catalog

Do this before your reps start building Powerwall 3 designs the new way. Step 3 is optional. If your account includes partner or dealer organizations, step 4 is required.

1. Enable the individual components

In the component database, enable:

• Powerwall 3 — the base unit
• Powerwall 3 Expansion — the expansion unit

These are what replace the bundled combo pack entries. Reps select the base unit and set an expansion unit count, rather than picking a pre-bundled component.

2. Set and check pricing

Set a price on the Powerwall 3 component and a price on the Powerwall 3 Expansion component.

This step matters more than it looks. Storage component prices are captured when the first component of that type is added to a project, so prices need to be in place before designing — otherwise storage can show as zero on new projects. If your prices were only ever set on the combo pack components, the individual components may have no price at all.

Build a test design and confirm the totals match what your combo pack pricing produced. See Pricing and Financing Defaults for how to configure storage pricing.

3. Disable the combo packs (optional)

Once pricing checks out, you can disable the combo pack components in your component database. You don't have to wait for the deprecation date — turning them off early keeps reps from picking one out of habit and keeps your dropdowns clean.

Disabling combo packs does not affect past designs. Designs that already reference a combo pack keep working exactly as they do today. Disabling only controls what's selectable going forward.

If you don't disable them yourself, they'll be deprecated automatically in early September.

4. Repeat for every partner organization

If your account includes partner or dealer organizations, this step is required — not optional.

Components and pricing are assigned per partner. Enabling Powerwall 3 and Powerwall 3 Expansion at the tenant level does not automatically make them available to your partners, and partner users cannot enable components for themselves. If a partner organization still has only combo packs assigned when deprecation takes effect, their reps will have no Powerwall 3 option at all.

For each partner organization in your account:

1. Open the Partner profile.
2. Assign the Powerwall 3 and Powerwall 3 Expansion components to that partner.
3. Check any partner-specific price overrides. If pricing was set on the combo pack components for that partner, the individual components may have no price or the wrong price.
4. Optionally, unassign the combo pack components once you've confirmed the replacements work.

Work through your full partner list before the deprecation date. A partner you miss won't be able to quote Powerwall 3, and won't be able to resolve it without you.

See Assigning Modules & Components to Partners for the assignment steps.

If you sell as a partner organization

If your company sells under a parent installer or EPC's Aurora account, the steps above aren't yours to take. Which Powerwall 3 components you see — and what they cost — is controlled at the parent organization level.

If Powerwall 3 or Powerwall 3 Expansion isn't showing up for you, or the pricing looks wrong, contact the Aurora admin at your parent organization. They manage component assignments and partner pricing from the Partner profile in their account, and they're the only ones who can enable these components for your organization.

For reps: what to do instead

Adding a Powerwall 3

In Sales Mode:

1. Open a project in Sales Mode.
2. Click the battery icon in the top navigation bar to open the Storage page.
3. Select Powerwall 3 from the battery dropdown — not a combo pack entry.
4. Set the number of expansion units (up to 3 per base unit).
5. Click Simulate.

Powerwall 3 has no quantity field in Sales Mode — you set expansion units, not a base unit count. If the system needs more than one base unit, AutoStringer adds them when it strings the design. Multiple Powerwall 3 base units are supported in Sales Mode as long as they're the same battery type, so the design stays editable and you can keep adjusting expansion units from the Storage page.

This is what replaces the combo packs, including the multi-base ones. To replace "(2) Powerwall 3 + 2 Expansion Units," select Powerwall 3, let AutoStringer size the system, then set the expansion units.

In Design Mode:

1. Open the Create New Storage System modal (or the Create New Inverter modal).
2. Select Powerwall 3.
3. Set the number of expansion units in the field that appears.
4. Repeat for each additional base unit, distributing expansion units as the installed system will be configured.

Use Design Mode when you want to control the number of base units yourself rather than letting AutoStringer determine it.

In both modes, the Powerwall 3 and its integrated inverter are managed as a single component — the inverter follows its battery and can't be edited separately.

What happens to my existing designs?

Nothing breaks. Designs that already use a combo pack component will continue to work, simulate, and quote normally — both after the deprecation date and if an admin disables combo packs early. Deprecation prevents a component from being added to new designs; it does not remove it from designs that already reference it.

If you want to use the new storage structure on an existing project, you'll have to recreate the project once your tenant has access to the storage update — there's no way to convert a legacy design at this phase.

FAQs

How do I know if I'm using a combo pack? Check your component database for battery entries whose names include a unit count — an expansion unit count like "Powerwall 3 + 2 Expansion Units," a base unit count like "(2) Powerwall 3," or both. If your reps are selecting one of those, you're using a combo pack.

Can I disable combo packs before the deprecation date? Yes. Admins can disable them in the component database whenever they're ready, and doing so has no effect on past designs. Just make sure the Powerwall 3 and Powerwall 3 Expansion components are enabled and priced first.

How do I add more than one Powerwall 3? You don't add them manually in Sales Mode. Select a Powerwall 3, and if the system needs more than one base unit, AutoStringer adds the rest when it strings the design. You can adjust expansion units afterward, and multiple base units of the same type stay editable in Sales Mode. If you want to control the number of base units yourself, use Design Mode.

Can I keep using combo packs after the deprecation date? Not on new designs. Existing designs that reference them will continue to work.

Will my quotes or pricing change? Capacity and output stay the same — the same hardware is being represented, just as separate components. Pricing depends on your component database. Confirm your admin has set prices on the Powerwall 3 base unit and the expansion component so totals match what your combo pack pricing produced.

Does this affect my TPO or financing integrations? Yes — for the better. Because the base unit and expansion units are now modeled as separate components, Aurora sends financing partners a more accurate representation of the system. Combo packs bundled multiple pieces of hardware into a single object, so the equipment and quantities submitted didn't always reflect what was actually being installed.

I don't see the expansion units field. What's wrong? Your tenant may not have been reached in the phased storage rollout yet. Contact your CSM or Aurora Support to confirm your status. If you sell as a partner organization under a parent installer, check with the admin at that parent organization first — they control which components are available to you.

I'm a partner org — can I enable the components myself? Component assignments and partner pricing are managed by the admin at your parent organization, from the Partner profile in their account. Reach out to them to get Powerwall 3 and Powerwall 3 Expansion enabled and priced for your organization.

Are other combo packs affected? This change covers Powerwall 3 combo packs. Other bundled components in your catalog are being reviewed separately; your account manager will reach out if any of yours are affected.
