MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202441068601 A) filed by Mrithumjayan Jayakumar Jayabhavan, Alappuzha, Kerala, on Sept. 11, 2024, for 'solar off grid control panel.'
Inventor(s) include Mrithumjayan Jayakumar Jayabhavan.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "Nowadays many incentives are given to the house holds for the installation of solar panel and energy production through the solar panel. As the On Grid system is costly and cumbersome, many households have converted their existing home inverter to a solar management unit by adding a solar panel and an MPPT ( maximum power point tracking) which is a charge controller whose input is the solar panel voltage. During day time the MPPT charges the home inverter battery to a set voltage level and the grid supply to the home inverter is disconnected in the morning to deliver power to the connected load on the inverter line of the house. In the evening, when the sun light diminishes, the MPPT connects the home inverter back to the grid supply when the battery voltage downs to a set voltage in the MPPT settings. Thus around 1.2 KW of electricity is saved daily through this method depending upon the load connected to the inverter line of the house and availability of sunlight. A major drawback of this arrangement is, when the MPPT re-connects the home inverter to the grid power in the evening, the home inverter charges the battery to a set voltage level in the home inverter and thereby grid power is used for the battery charging. This charging consumes nearly 1 KW and thereby the energy saved during day time through the solar power is nullified. Moreover due to a voltage sensing transformer in the home inverter which is energized all the time, a power consumption of 10 watts/hour happens due to the inverter connection even if there is no power failure and every time when the power fails, the inverter consumes nearly 1KW for charging the discharged battery to the set levl of voltage in the inverter. The invention has taken care of all these drawbacks in the off grid system integrating the existing home inverter and ensures a power saving of 36 KW (1.2 kW for 30 Days) by reducing direct consumption, 7 KW avoiding the constant daily charging of the batteries through the home inverter (10 watts daily for one month) and another 6 KW assuming a power failure happens 6 times in a month. Thus nearly 50 KW of energy can be saved by installing this invented device in solar off grid system in the households. Unlike the On Grid system, where the consumers are lured to consume more energy, this type of Off Grid system brings a sense of reduction in energy consumption in the consumers as they get subsidies from the government for lesser energy consumption."
