Advanced bidirectional power systems optimized for tropical grid stability
Costa Rica stands as a beacon of renewable energy, generating over 99% of its electricity from green sources like hydro, wind, and geothermal. As the nation pushes toward its goal of becoming carbon neutral by 2050, the adoption of Electric Vehicles (EVs) has surged. However, the next frontier in this "Pura Vida" energy journey isn't just driving electric—it's using those vehicles as mobile power plants.
In regions like Guanacaste or the Osa Peninsula, tropical storms can occasionally disrupt local grids. V2H technology allows Costa Rican homeowners to use their EV battery to power essential appliances, ensuring continuity during outages.
Boutique eco-hotels and lodges in remote areas are increasingly integrating V2H systems. By discharging EV energy during peak hours, these businesses reduce their carbon footprint and operational costs.
Under Law 9518, Costa Rica offers significant tax exemptions for EVs and charging infrastructure. Implementing V2H bidirectional chargers further optimizes the ROI of an EV investment for local businesses.
Dongguan Rama Charger Technology Co., Ltd. is a technology-driven enterprise integrating R&D, design, manufacturing, sales, and service into a seamless operation. We specialize in providing comprehensive system energy solutions for electric vehicle charging and related applications.
With strong independent R&D capabilities in charging controllers, Rama Charger can provide customized core master control boards for charging pile manufacturers. Over the years, we have established collaborations with numerous leading charging pile enterprises domestically and internationally, delivering outstanding ODM results and tailored solutions for the Costa Rican and Latin American markets.
Our headquarters has obtained multiple authoritative certifications, including DEKRA CB, CE, ISO9001, as well as recognition as a high-tech enterprise and technology SME. We maintain a robust quality management system and AAA credit rating, and have secured 15 software copyrights, multiple invention patents, utility model patents, and design patents.
Costa Rica's commitment to the National Decarbonization Plan makes it a primary market for bidirectional charging technology. Unlike many regions that still rely on coal or gas, Costa Rica’s energy surplus from hydro and wind can be stored in EV batteries during the night and returned to the home or grid during peak hours. This creates a "Virtual Power Plant" (VPP) ecosystem that is highly attractive to local energy providers like ICE (Instituto Costarricense de Electricidad).
For exporters and manufacturers, Costa Rica serves as a gateway to the Central American market. By partnering with Dongguan Rama Charger Technology, local distributors can leverage high-tech ODM solutions that are already compliant with international standards (CE, CB) and adaptable to the NACS or CCS2 standards commonly found in imported North American and European EVs.
Our V2H modules utilize Advanced Silicon Carbide (SiC) MOSFETs, which offer higher efficiency and lower heat dissipation—a critical factor in Costa Rica's warmer climate zones. Whether it's a 7kw wallbox for a residence in Escazú or a 44kw unit for a commercial fleet in San José, our technology ensures minimum energy loss during the AC-to-DC and DC-to-AC conversion process.
