Master Battery , a Spanish-owned company specializing in autonomous energy production and distribution , is participating in PVBook 2025 , the international catalog developed by Energía Estratégica , with a comprehensive range of products designed to boost projects linked to the energy transition at different scales.
With an industrial network spread across Europe and Asia , the firm guarantees exhaustive quality control in its production lines and builds bridges of international collaboration, standing out for its offering that ranges from technical consulting to the delivery of turnkey systems .
“We offer our clients a comprehensive and valuable offering that ranges from consulting to project development and integration into their applications,” the company emphasizes in its catalog.
Among the products on display are hybrid inverters, off-grid solutions, and high-durability lithium batteries, designed to meet the diverse needs of today’s energy market.
One of the keys to Master Battery’s positioning is its technical approach focused on its own engineering , which allows it to design and adapt specific solutions for each client and application.
This differential translates into systems that are modular, scalable, and parallelizable , designed to maximize flexibility in BESS projects, self-consumption, and smart microgrids. The company offers all-in-one plug-and-play systems and custom developments.
These features are especially attractive to EPCs, developers, and utilities looking to reduce installation and operation times without compromising technical reliability.
Within the Master Battery portfolio in the PVBook, the “Omega UM V5 6K” off-grid inverter stands out , with a nominal power of 6,000 W , a battery voltage of 48 V and a maximum efficiency of 93% , specially designed to operate in isolated grid environments.
In turn, the “GreenE 5K” model , a hybrid inverter with 5,000 W output and up to 6.5 kW of photovoltaic power, reaches a maximum efficiency of 97.6% and operates with a wide MPPT voltage range between 80 and 560 V , ideal for residential or commercial installations that integrate solar generation and storage.
The catalogue is completed with two models of LiFePO4 batteries , recognised for their robustness, thermal stability and high number of useful life cycles , ensuring reliability and low operating costs in the long term.
The UE-12L1100 offers a nominal capacity of 100 Ah and up to 2,500 cycles , with the option of connecting up to 4×4 units in parallel and series. Meanwhile, the UE-48LI51201 achieves a lifespan of over 6,000 cycles and can connect up to 50 units in parallel , adapting to large-scale projects.
“Our LiFePO4 batteries exceed 10,000 cycles, with solutions that can be connected in parallel to adapt to any energy need,” Master Battery emphasizes.
In line with this comprehensive proposal, the firm projected a participation of 34 GWh in projects in 2024 , consolidating its growth as a global provider of storage solutions.
Participating in PVBook allows us to showcase the scope of our solutions and strengthen strategic relationships throughout the region. And with solutions geared toward energy autonomy, Master Battery is positioned as a key player in the BESS ecosystem , integrating robust hardware with intelligent design.
