1. Company Overview
Wallbox was founded in 2015 in Barcelona, Spain, by Enric Asunción and Eduard Castañeda, with a mission to reinvent home EV charging as a smart, design-forward energy product. The company grew rapidly across Europe and expanded into North America, going public on the New York Stock Exchange in 2021 under ticker WBX. Wallbox designs and manufactures its chargers in Europe, with production facilities in Barcelona (including a dedicated factory inaugurated for North American Pulsar production) and Zerland, with the Atlas processor developed in-house. The company's product philosophy centers on compact, attractive hardware paired with a top-rated app and OCPP-compatible backend for commercial fleet and workplace deployments.
Wallbox serves residential, commercial, and public charging segments across Europe, North America, and parts of Asia and Latin America. Its three Barcelona production lines are dedicated to the Supernova public charger, the Pulsar for North America, and the Copper, Commander 2, and Quasar lines for Europe. The company has positioned itself at the intersection of EV charging, solar energy, and home energy management.
2. Current Product Lines

3. Recent Releases (2025–2026)
The headline release is the Quasar 2 bidirectional charger. Wallbox began U.S. pre-orders with deliveries expected in June 2025, making the United States the first market to receive the Quasar 2, with Europe and other markets to follow. The Quasar 2 enables Vehicle-to-Home (V2H) — powering the home during outages or peak demand — and Vehicle-to-Grid (V2G), supporting grid stability and earning incentives by feeding energy back. It also enables time-of-use optimization: charge when rates are low, discharge when they are high ([Wallbox](https://wallbox.com/en/blog/how-solar-powered-ev-charging-driving-future-home-energy)).
The Pulsar Max represents Wallbox's next-generation home charger, featuring the in-house Atlas processor for faster app performance and OCPP 2.0.1 backend compatibility, advanced solar optimization (3-phase-to-1-phase switching for up to 200% more daytime solar charging), an IP55/IK10 rugged enclosure, and operation to 50°C. The Pulsar Pro continues to serve shared commercial environments with secure authentication and metering. Wallbox inaugurated its third Barcelona factory with dedicated production lines for the Supernova public charger and North American Pulsar, scaling capacity for growing demand.

7. Technical Comparison: Wallbox vs. Competitors
| Criteria | Wallbox | ChargePoint Home Flex | Tesla Wall Connector | Grizzl-E |
|---|---|---|---|---|
| Max L2 power | 22 kW (Pulsar Max) | 12 kW (50 A) | 11.5 kW (48 A) | 10 kW (40 A) |
| Bidirectional (V2H/V2G) | Yes (Quasar 2) | No | Limited (Tesla) | No |
| Solar optimization | Yes (Eco/Full-Green + 3P) | Limited | No | No |
| OCPP 2.0.1 | Yes (Pulsar Max) | Yes (commercial) | No (proprietary) | OCPP 1.6 |

Wallbox's differentiators are bidirectional charging (Quasar 2 is the most accessible V2H/V2G charger on the market), advanced solar optimization with 3-phase switching, OCPP 2.0.1 compatibility, and top-rated app experience. Its warranty (2 years) is shorter than ChargePoint's (3 years) but the feature set leads the residential category.
8. Installation Notes
- Circuit sizing: Size the branch circuit at 125% of the EVSE's maximum continuous draw per NEC 625.42 — a 40 A charger needs a 50 A breaker. Pulsar Plus at 32 A needs a 40 A circuit; Pulsar Max at 32 A (3-phase) similar.
- Hardwire vs. plug-in: Wallbox chargers above 40 A should be hardwired. For plug-in installations, use an outdoor-rated NEMA 14-50 or 6-50 receptacle. ChargePoint recommends hardwiring for optimal performance.
- Solar integration: Enable Eco Mode to blend grid and surplus solar, or Full-Green Mode for solar-only charging — ideal for net-zero homes. The 3-phase solar optimization feature boosts daytime solar use by up to 200%.
- Bidirectional (Quasar 2): V2H requires a compatible bidirectional EV, a transfer switch or interlock for islanding, and proper permitting. Verify vehicle compatibility before specification.
- Panel capacity: Verify panel capacity using NEC 220.87 (metered demand) or 220.83 (nameplate). Consider an EVEMS for multi-charger or tight-panel installations to avoid a service upgrade.
- Surge protection: The 2026 NEC requires surge protection for all new and replacement EVSE. Add a Type 2 SPD at the panel. See our surge protection guide.
- Conduit & wiring: Pull the correct cable per NEC; use conduit where required for physical protection.
9. Frequently Asked Questions
Does Wallbox work with solar panels?
Yes. Wallbox's Eco Mode blends grid and surplus solar power for consistent charging while maximizing solar contribution, and Full-Green Mode charges the EV with solar energy only once enough surplus is available. The 3-phase optimization feature boosts daytime solar charging by up to 200%.
What is the Quasar 2 and how does bidirectional charging work?
The Quasar 2 is Wallbox's bidirectional charger enabling Vehicle-to-Home (V2H) — powering your home during outages or peak demand — and Vehicle-to-Grid (V2G), feeding energy back to the grid for incentives. It uses an internal DC-to-AC converter and communicates with the EV per ISO 15118-20.
What is the difference between Pulsar Plus and Pulsar Max?
Pulsar Max is the next-generation home charger with the in-house Atlas processor, OCPP 2.0.1 compatibility, an IP55/IK10 rugged enclosure, advanced 3-phase solar optimization, and operation to 50°C. Pulsar Plus is the established flagship with Eco/Full-Green solar modes.
Does Wallbox support OCPP for commercial networks?
Yes. Pulsar Max and commercial models (Pulsar Pro, Commander 2) support OCPP 2.0.1, enabling integration with third-party backends and energy management systems — ideal for apartments, workplaces, and fleets.
What warranty does Wallbox offer?
Wallbox chargers come with a 2-year limited warranty covering defects in materials and workmanship. The chargers are designed and manufactured in Europe and built to last. Warranty requires installation by a qualified electrician per local codes.
