MICROTEK Micro-Controlled based High Efficiency,PWM SOLAR MANAGEMENT UNIT (SMU) is best suited for Low-Power Solar Applications. Microtek introduces a new and unique device 'Solar Management Unit ". SMU (solar management unit) is a special and unique Indian device that converts your simple Inverter into a Solar Inverter. -The same SMU works on both 12V & 24V inverters. The charging process is designed for long battery life and improved system performance. Comprehensive self-examination and extensive electronic protection can prevent damage to the wrong cable or system errors. When the sunlight is full the solar charge controller charges the solar battery with the first value of solar energy, when the battery is fully charged, it runs the load from the sun and automatically starts to move the load to the power back in the evening. The solar management unit gives priority to the solar panel. In this SMU, you get a built-in PWM Solar Charge controller, which maintains the efficiency of solar panels and solar battery life for a long time. The best part of Microtek SMU (solar management unit) is that it operates on a single inverter with one or two batteries. It has great features in automatic battery selection. Available in 12V or 24V with 1 year warranty. BENEFITS OF SOLAR MANAGEMENT UNIT High speed with high performance The Microtek (SMU) solar management unit is equipped with a high-speed microcontroller that increases the efficiency of the solar system. The solar management unit provides the ability to perform its function reliably and efficiently. High Reliability with Long Work Life It is very reliable and has a long working life. The solar management unit can operate in extreme environmental conditions and can be operated at a temperature range of 0 ° C to 60 ° C. Prioritize solar energy over grid power SMU ensures the use of more solar energy in addition to state electricity (grid) to reduce grid use. In daylight mode, the system will prioritize solar energy and use grid power only when solar energy is insufficient to support the load requirement. Extend battery life SMU uses four stages of battery charging that improve battery life. In the bulk phase SMU supplies the battery with continuous charging power until its capacity reaches 14.4V and float current, and in the suction phase it maintains this voltage above 14.2V for three hours. Auto / manual operation The system can work as a home inverter and a solar inverter automatically or manually by switching out of the night mode. In the night mode, it will first harvest the stored battery power and then act as a standard home inverter. Protection Designed to Avoid Battery Charging and Overcharge SMU has the ability to charge a solar battery that goes into a deep discharge mode. It can charge the battery if the battery capacity at the time of discharge reaches 8V per battery. The solar control center uses four stages of battery charging namely Boost, Absorption, Float and Equalization. This feature protects the battery from overcharging. Very Low Consumption in Inactive Condition It has very low consumption of inactivity, in the case of inactivity it uses less than 20mA current making it more efficient than any other solar management unit. Electronic protection By charging Voltage, By charging Current charges, Under power, Protection of battery reverse polarity, Solar protection from solar polarity, Convert current night flow from battery to solar components, Above temperature, Solar Low Voltage
