DATASHEET FOR SOLAR MONITORED INVERTER (SMI) 1/1 -10KW 10 KW Solar Monitored Inverter (SMI) Brief SMI series online Solar Monitored Inverter (SMI), a fully intelligent digital Solar Monitored Inverter (SMI), highly combines the latest controller and the most advanced software. It takes the sixth generation low-exhaust and big-power IGBT and static switch as power devices. This kind of Solar Monitored Inverter (SMI) is a perfect production of Baykee. It adopts the digital controlling technology, of which the core is high-speed on-line programmed microprocessor. Application Apply to Computer center, Network management center, Communication system, Automatic control system, ATM; Precision instrument and equipment, household appliances etc. widely apply to Home, Industrial. Feature:  Pure sine wave output, true on-line dual conversion design  Adopt 4 layer PCB, and SMD technology.  High efficiency IGBT (Insulated Gate Bipolar Transistor) inverter technology the sixth generation low-exhaust and big-power IGBT with excellent high speed switch feature, high voltage feature and large current feature. Drives by electric voltage, only need small control power. The sixth generation with lower saturation voltage, the inverter has high efficiency, low temperature, high reliability.  Touch screen display, with the simple operation and Intuitive data. Set the work mode on the display directly, INVERTER mode, ECO mode, EPS mode.  Intelligent detecting function - this system microprocessor can continually online detect power status, the breaker status and all the working status of the circuit.  Excellent load feature - It is completely capable to load from 0-100% while no need to change to bypass, which make sure the output reliable.        Cold start - When mains failure, can directly use the battery to start the inverter until the battery discharge to low voltage, when mains recover, can self-start Solar Monitored Inverter (SMI). Generator compatible - Solar Monitored Inverter (SMI) is compatible to the generator highly improves the generator input efficiency, save the energy. Intelligent communication - With RS232 and RS485 standard collocation, optional SNMP and dry contact Perfect protection - Input/output over/low voltage protection, input surge protection, phase sequence protection, battery over charge/discharge protection, short circuit protection, over-temperature protection and so on, as well as alarm function. Selectable battery inspection module - can test the single parameter and display on the LCD, battery failure will immediately alarm and inform the administrator. High-powered dynamic feature - adopt kinds of feedback control such as instantaneous control mode and virtual value, not only reach the high dynamic adjustment, but also reduce the output voltage distortion. Input harmonic filter - effectively restrain the input THD, raise Solar Monitored Inverter (SMI), input power factor and reduce the input THD current.
