SPS Mppt Solar Hybrid Inverters.
These are Mppt based solar hybrid inverters and are equipped with inbuilt MPPT Charge Controller. They have DSP based Intelligent technology and have a LCD based display for showing of parameters like battery voltage, charging current, output voltage, input voltage, solar voltage, solar current, solar output, daily KW/H, total KW/H etc and LED’s for showing inverters functionalities like inverter on, solar on, battery float, battery charging etc. They have inbuilt status Protection against reverse polarity and have a Dynamic short circuit protection with fold-back current limiting capacity. They have Protection against all possible errors like battery low, overload, heavy load, short circuit etc. They will give an early warning for battery low and overload conditions and system continues normally if the errors is corrected. These inverters are Ideal for mixed load applications. They have a Indigenous design with proven technology. They are equipped with the Generator compatibility enabled. They have UPS ,Inverter mode selection switch to switch between UPS and Inverter. These are Pure sinewave inverters and are safe to all kind of loads. These inverters are based on switching MOSFETs. They have the Priority Solar Charging mode or otherwise called hybrid mode. In Hybrid mode, they will enable the inverter to charge the battery by sensing the solar light at day time and charge from grid when the solar light is absent. So grid energy and solar energy will be utilised based on the light availability. Hence the name hybrid. If this Solar Mode/Hybrid Mode switch is OFF , the Inverter will be in Hybrid mode. In this mode, inverter will charge from both solar and grid. If Solar present, it will charge the battery from Solar. If solar light is not detected, then it will charge from Grid/mains. If Solar Mode/Hybrid Mode switch is ON , then the Inverter will be in Solar mode. Inverter will charge the battery from Solar Only. These inverters are compactible with both Lithium and lead acid battery types. These inverters available in both aluminium and copper based transformers. Care should be taken while connecting the battery and Solar panels to this inverter. Always connect the battery first, then connect the solar panel.
