ENERGY MANAGER (STK)
Sunways STK is a bidirectional smart meter supporting various grid voltages and grid types, which collects voltage, current, active power, reactive power, active energy, reactive energy, and other information and records the real-time power and energy that feed in and take from the grid. Together with Sunways monitoring system, the STK records and presents various energy flows data such as self-consumption. Thanks to the rapid communication with Sunways inverters via Modbus RTU interface, it can fast process export limitation & control with on-grid inverter and realize perfect coordination among hybrid inverter, PV string, battery, grid and loads, optimized the whole system energy management and improved self-sufficiency rates. STK also integrated another feature of record and present self-sufficiency, energy flows and other information around the clock.
