Guess What Just Left the Factory? 10 set SUNDTA 51.2V 100Ah Rack Batteries for Cuba!

HEFEI, China – SUNDTA has announced that its 51.2V 100Ah high-voltage rack-mount lithium battery has successfully completed production and passed all factory testing protocols. Marking a new milestone in the company‘s global market expansion, ten complete sets of the high-voltage rack-mount lithium battery system have been prepared and are now scheduled for packaging and shipment to Cuba.

Developed to meet the growing global demand for modular and scalable commercial energy storage solutions, the SUNDTA 51.2V 100Ah high-voltage rack-mount lithium battery system delivers a range of advantages that place it on equal footing with leading global brands. Based on advanced LiFePO₄ cell chemistry, the battery features high energy density, a compact footprint, and superior safety performance under continuous high-duty cycling. The module design supports energy expansion by adding additional racks, allowing commercial and industrial users to scale capacity incrementally without the need for system-wide redesign, while achieving round-trip efficiency of over 90% and lifecycle performance exceeding 6,000 cycles beneath 80% depth of discharge. Each battery is equipped with an intelligent Battery Management System (BMS) that provides comprehensive protection against over-discharge, over-charge, over-current, over-high temperature, and low temperature, while automatically balancing current and voltage across individual cells, extending battery life and maintaining long-term capacity stability.

The shipment to Cuba arrives at a pivotal moment for the Latin American nation as it intensifies its energy infrastructure transformation. Cuba is currently advancing a 100-solar-park program with a total installed capacity of 2,000 MW, part of which has already begun operations, while simultaneously constructing 50 MW battery storage systems across four substations to address grid stability challenges. With solar parks already covering an estimated 49% to 51% of Cuba‘s daytime electricity demand, the integration of high-voltage rack-mount lithium storage systems is critical for maximizing solar utilization and reducing reliance on thermoelectric generation.

Beyond the battery modules themselves, SUNDTA distinguishes itself by offering a complete turnkey photovoltaic energy storage solution. Customers partnering with SUNDTA receive a 100kW + 100kWh Energy Storage System that integrates 100kW energy storage inverters (bidirectional hybrid PCS), solar panels, mounting systems, energy management systems (EMS), and BMS-controlled battery racks into a fully coordinated solar-storage platform. This approach eliminates the complexity of coordinating multiple suppliers, ensures component compatibility, and streamlines the entire project lifecycle from design through commissioning.

Recognizing that successful energy storage deployment in emerging markets demands not only premium hardware but also specialized technical expertise, SUNDTA further differentiates itself by deploying professional engineering teams to customer locations. When a client orders a high-voltage rack-mount battery system along with the corresponding energy storage infrastructure—including 100kW energy storage inverters, PV array configurations, and EMS integration—SUNDTA can dispatch its technical specialists directly to the project site to provide on-site installation guidance, system commissioning, and operational training. This hands-on engineering support ensures that each system is configured for maximum efficiency, proper BMS communication, and seamless inverter-battery coordination under local grid conditions.

As the world‘s energy storage sector continues its rapid expansion, SUNDTA remains committed to delivering both high-performance hardware and integrated, customer-centric services that enable clients across the globe to build resilient, future-ready solar-storage ecosystems.
