Designed to comply with European network codes (EN 50549-1) and localized Spanish zero-export and self-consumption standards.
The metropolitan region of Barcelona, spanning major industrial hubs like Zona Franca, Mercabarna, and the Vallès Oriental, is experiencing a fundamental transition in how energy is generated and distributed. Guided by Catalonia's ambitious self-consumption policies and the *Pla de l'Energia i el Clima de Catalunya*, local businesses and grid operators are adopting advanced hybrid energy storage systems (BESS). These systems manage load volatility, reduce dependence on Endesa's distribution infrastructure, and mitigate high demand charges (término de potencia).
Our hybrid solar inverters serve as the centralized brain for these microgrids. By combining high-efficiency MPPT trackers, battery charging management, and multi-directional grid interfacing into a single platform, these systems maximize self-consumption. In dense urban and industrial settings in Barcelona, space constraints require high-power density hardware capable of managing dynamic grid requirements. Our units ensure seamless compliance with RD 244/2019 and RD 1183/2020, delivering smooth zero-export operations and active frequency control.
All hybrid inverters dispatched to Catalonia are built with integrated energy monitoring and anti-backfeed control conforming to Spanish UNE 217001 regulations. This allows commercial operators in Barcelona to bypass complex grid injection authorization delays by installing pre-configured, physical zero-injection loops.
Ensuring grid stability and backup capability for agricultural estates, logistics centers, and telecom infrastructure in Catalonia.
Modern solar installation projects require high engineering standards. At our factory, we build inverter topologies utilizing high-frequency isolation and high-performance Silicon Carbide (SiC) MOSFET switches. These choices reduce switching losses and maintain system efficiency above 98.2%. The multi-core processor configuration inside our control board responds to load swings in under 10 milliseconds, preventing transient back-feeds into the local distribution grid.
Our three-phase hybrid inverters feature asymmetrical phase loads, allowing installers to deliver up to 100% of nominal power on a single phase. This is highly useful for older commercial buildings in downtown Barcelona, where single-phase load distribution is often uneven. It eliminates the need for expensive phase-balancing autotransformers.

Designed for commercial complexes, high-voltage battery storage installations, and demanding industrial applications.
Reliability in energy assets is non-negotiable. That is why Luzz Solar integrates localized support services, providing prompt delivery, custom configurations, and compliance assurance. Our inverters carry all necessary European grid compatibility documentation.
The convergence of solar generation, energy storage, and Electric Vehicle (EV) fast-charging infrastructure requires intelligent control systems. Our current hardware roadmap focuses on integrated Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) bidirectional interfaces.
Through AI-assisted firmware updates, our inverters calculate dynamic tariff changes (*tarificación regulada PVPC*) in Spain to charge connected EV batteries during low-cost hours and discharge power back into the facility during peak pricing periods. This turns your commercial vehicle fleet into a distributed battery resource.
Answering high-level engineering and regulatory questions from commercial clients, EPCs, and installers in Spain.
Our inverters feature integrated telemetry ports that interface directly with external smart meters and CT clamps. The firmware runs a high-speed control loop (processing under 10ms) that dynamically adjusts the inverter output to match the building's load. This prevents any backflow of electricity to the local distribution network (e.g., Endesa), fulfilling all regulatory criteria for zero-injection systems in Spain.
Yes, our three-phase commercial hybrid inverters support 100% unbalanced loads across all three phases. If Phase A requires 6kW, Phase B requires 2kW, and Phase C requires 0kW, the inverter balances output dynamically via internal circuitry, eliminating grid consumption without requiring external balance transformers.
Our charge controllers feature pre-configured CAN and RS485 communication protocols for major battery brands using Lithium Iron Phosphate (LiFePO4/LFP) chemistry. They also support lead-acid (gel/AGM) batteries. The open BMS protocol allows for custom battery profile mapping via our PC configuration software.
We maintain regular production batches at our main plant, with direct sea and rail cargo options to the Port of Barcelona. For local projects, we supply commissioning documentation, remote diagnostic assistance, and hardware replacement support through regional logistics partners.
