DC coupled solar + energy storage solution

Alencon Systems LLC's SPOT (String Power Optimizer and Transmitter) is a string level DC-DC optimizer which optimizes the power from PV string inputs with voltages ranging from 600V to 1500V. The SPOT-ES family of products has been specifically designed for the needs of DC-coupled Solar + Storage deployments. The SPOT-ES V5 includes a true 1500V input based on 1700V rated Silicon Carbide (SiC) rated mosfets, an ability to map a wide battery charge/discharge voltage range, reliability enhancements developed in concert with Solar + Storage technology providers and integrators, as well as flexible communications options for better integration with Solar + Storage and Microgrid control systems. The SPOT-ES's galvanic isolation concept isolates the PV input from the output by attaching isolation transformers to each PV input. This technique provides a unique benefit in the DC-coupling of Solar + Storage because the integral magnetics to the SPOT can be easily configured from one deployment to another to easily support a broad battery charge/discharge DC-bus voltage, where the voltage range could vary by as much 20% from complete discharge to full charge. The SPOT-ES V5 includes an ultra-fast circuit to protect it from sudden system power output overloads. The SPOT-ES V5 features enhanced communications features to allow it to be interfaced with third party system controllers via either Modbus TCP, for communicating to the SPOTs wirelessly, or Modbus RTU, which allows for hardwire communication to each SPOT directly. The enhanced communication functionality offered in the SPOT-ES V5 allows for granular control over the PV, including the ability to curtail production at the string level.
