This integration eliminates the need for separate components, simplifying installation and reducing costs. Connect your PV modules directly to the base of the SMC200, and experience a seamless, cost-effective solution that maximizes energy harvest with minimal complexity.

Built for High Voltage PV Modules  

Designed to keep pace with the evolution of solar technology, the SMC200 is suitable for high voltage PV modules. It boasts an impressive MPPT voltage range of 900V to 1300V, ensuring optimal performance even under demanding conditions. Paired with an output voltage range of 600V to 900V (700V-900V at full load), the SMC200  delivers up to 200kW of charging power with a maximum charge efficiency of 99%. Whether you’re working with lead-acid or lithium-ion batteries, this controller adapts effortlessly.

High Ingress Protection and Compact Design  

The SMC200 is engineered for durability and practicality. With an IP65 protection rating, it excels in outdoor environments, offering excellent waterproofing and resistance to harsh weather conditions. Its compact dimensions (780/770/210 mm) and lightweight build (65kg) make it a smart choice for easy installation and space-saving container solutions. Despite its small footprint, the SMC200 doesn’t compromise on power, featuring intelligent fan cooling to maintain performance in temperatures ranging from -25°C to +55°C. This blend of ruggedness and efficiency ensures long-term reliability without the hassle.

Comprehensive Protection for Peace of Mind  

Safety and stability are at the core of the SMC200’s design. It comes equipped with various types of protection, including input and output over/under voltage protection, overcurrent protection, short circuit protection, overheat protection, and Type II lightning protection. Additional features like a built-in DC breaker and emergency shutdown functionality provide an extra layer of security, making it a dependable choice for mission-critical solar projects. With the SMC200, you can trust that your system is safeguarded against the unexpected.

Scalability with Multiple Units Parallelable  

Flexibility is crucial for large-scale solar deployments, and the SMC200 excels with its parallelable design, allowing unlimited grid-connected units. Its modular architecture allows you to scale up effortlessly by connecting multiple SMC200 units, accommodating projects of varying sizes. This scalability, combined with a transformerless topology, ensures maximum efficiency and adaptability, making it an ideal solution for growing energy needs. This press-need investment approach minimizes upfront costs and allows phased expansion, making it versatile for projects of varying scales, from remote microgrids to large industrial setups. 

A Unified Energy Storage System for Maximum Impact

The SMC200 is designed to work hand-in-hand with ATESS PCS battery inverters (100kW to 1MW), including American-standard models. Supporting both AC and DC coupling, it mates with all ATESS PCS series , enabling flexible on/off-grid solutions. Up to 8 PCS units can be paralleled off-grid, delivering megawatt-scale power for high-demand applications.

The SMC200 is the cornerstone of ATESS’s comprehensive energy storage solutions. When integrated with ATESS PCS battery inverters, Bypass cabinets , and battery systems (e.g., BR172R–215R), it ensures seamless on/off-grid transitions within 10ms. This energy storage systm supports diverse applications, including peak shaving, grid regulation, and self-consumption, while ATESS battery solutions with 3-level BMS and high battery capacity provide reliable energy storage. The system’s redundancy, high stability, and remote monitoring via the ATESS Enerclo cloud platform guarantee operational excellence.

Look at the SMC200: a solar charge controller and PV combiner in one, with 8 built-in MPPTs for direct PV connection at its base. It’s convenient, cost-effective, and ready to power the future.
