Ultimate Guide to Finding Sonnen Porsche Parts Locations in the US

If you own a Sonnen Porsche—a classic Porsche converted to electric drive by the German company Sonnen—you know that sourcing specific parts can be a challenge. Whether you need a replacement battery pack, a motor controller, or a custom adapter plate, knowing where to look is essential. This guide covers the most reliable places to find Sonnen Porsche parts in the United States, along with practical advice to keep your conversion running smoothly.

Where to Find Sonnen Porsche Parts

Directly from Sonnen

The first and most obvious source is Sonnen itself. Although Sonnen is primarily known for home energy storage, their Porsche conversion division in Germany still supplies parts for existing conversions. Contact their support team via email or phone. Be prepared to provide your VIN or conversion serial number. Shipping from Europe can take several weeks and incur duties, but you get genuine parts and compatibility guarantees. For critical components like the battery management system or high-voltage wiring, direct ordering is often the safest route.

Specialized EV Conversion Parts Suppliers

Several US-based companies focus on electric vehicle conversion components. They may not carry dedicated Sonnen parts, but their universal components often work with Sonnen’s architecture. Look for suppliers that sell:

• Battery modules – LiFePO4 or NMC packs with similar voltage and capacity.
• Motor controllers – Compatible with the AC induction or permanent magnet motor Sonnen uses.
• Chargers – Onboard chargers that match the Sonnen BMS communication protocol.

Popular suppliers include EV West, EVolve Electrics, and Thunderstruck Motors. Call them with your Sonnen specs to confirm compatibility.

Porsche Classic Dealers

Some components on a Sonnen Porsche are still standard Porsche parts—brakes, suspension, body panels, interior trim. For those, visit an authorized Porsche Classic dealer. They have access to original parts and aftermarket options. Use the Porsche Classic parts locator on their website to find a dealer near you. For the electric-specific items, they likely won’t help, but for the rest, it’s a reliable source.

Used & Salvage Parts Specialists

Because Sonnen conversions are rare, used parts occasionally appear through specialty salvage yards that focus on electric or imported cars. Check with:

• Electric car salvage yards – Places like Electric Auto Recycling or ReVolt Salvage may have components from wrecked EVs that cross-reference to Sonnen.
• Porsche breakers – Yards that dismantle Porsches (like Parts Pros or LA Dismantlers) might have standard Porsche parts you need.

Always ask for the exact part number and inspect photos before buying. Used batteries come with unknown health—consider a capacity test upon arrival.

Tips for Sourcing Sonnen Porsche Parts

Verify Compatibility with Your Conversion Serial Number

Sonnen made several iterations of their conversion kit. The parts from a 2015 Sonnen 911 may not fit a 2020 model. Always reference your conversion’s serial number when ordering. Keep a record of the original specifications sent by Sonnen.

Understand Voltage and Communication Protocols

Many aftermarket components claim compatibility but fail due to mismatched CAN bus protocols or voltage ranges. If you’re replacing a motor controller, you might need to reprogram it. Hire a technician experienced with EV conversions—preferably one who has worked on Sonnen vehicles.

Shipping and Import Considerations

For parts shipped from Germany, factor in lead times of two to six weeks. Customs duties apply (typically 2.5% to 4.5% for EV parts). Use a freight forwarder if your order is large. Keep copies of all invoices for warranty claims.

Leverage Online Forums and Clubs

Join the Sonnen Porsche Owners Group on Facebook or the E-Porsche forums. Owners often sell spare parts or know where to find them. These communities can be faster than commercial sources for rare items.

Final Recommendation

For maximum reliability, start with Sonnen directly for high-voltage and proprietary components. Use US-based EV conversion suppliers for items like chargers and contactors, after confirming compatibility via phone or email. For standard Porsche parts, visit a Porsche Classic dealer or a trusted Porsche specialist. If you’re on a budget, carefully source used parts from electric vehicle salvage yards, but be prepared for some trial and error. Keep detailed records of your conversion to simplify future parts searches. With the right approach, you can keep your Sonnen Porsche on the road for years to come.
