Aug.26-27th, São Paulo,Brazil

Kehua Tech captivated the energy industry at Intersolar South America 2025, showcasing groundbreaking advancements in energy storage and PV solutions, unveiling groundbreaking innovations that redefine performance standards across energy storage and solar technology sectors.

I: Grid-forming Energy Storage Innovations Take Center Stage

The highlight is undoubtedly the comprehensive energy storage portfolio, designed to meet the diverse needs of the Brazilian energy market. Advanced 1500V Containerized Energy Storage & Transformer systems (BCS8000K~10000K-C-HUD/T8 Series), which incorporate sophisticated safety mechanisms including real-time insulation monitoring and transformer surveillance systems. These solutions are engineered to perform reliably in South America's diverse climatic conditions, from high-temperature environments to coastal areas with salt exposure.

A particular focus was placed on the intelligent grid-forming capabilities of these systems, which provide crucial inertial support to stabilize grid operations with millisecond-level response times. This technology enables multiple critical functions including Black Start capability and VSG operations, making valuable solutions for evolving energy infrastructure.

The S³-EStore ESI215-100K-M system emerged as another star attraction, featuring remarkably fast grid switching capabilities that complete transitions in under 100 milliseconds. This integrated solution combines power conversion systems, battery technology, and smart controllers to deliver scenario-based power management tailored to specific customer requirements. Visitors were particularly impressed by the advanced thermal management system that maintains temperature differentials within 2°C at the pack level and ±1.5°C system-wide, ensuring optimal performance and longevity.

II: Smart Inverter Solutions for Diverse Applications

On the solar energy front, Kehua presented a robust lineup of three-phase string inverters designed for maximum efficiency and reliability. The SPI75K-BLV model stood out with its innovative 9-MPPT design achieving efficiency rates up to 98.8%, while offering exceptional protection ratings (IP66 + optional C5) that ensure durability in challenging environmental conditions.

The exhibition also featured the groundbreaking SPI350K-B-H X2 inverters, which support up to 75A maximum current per MPPT – making them ideally suited for large-current and bifacial module applications. These inverters incorporate intelligent temperature monitoring at both DC and AC terminals, coupled with PV shutdown functionality for enhanced system safety.

Kehua inverter solutions are designed for wide operating temperature ranges, ensuring high adaptability to various environmental conditions across diverse geography.

Intersolar South America attracted substantial attendance from energy professionals across the region. Kehua team engaged in productive discussions regarding application scenarios and technical specifications. Kehua is committed to pioneering energy transformation and co-creating a sustainable future.
