SOLAR ENERGY BASIC CONCEPT:
Solar power generation is a clean energy system that generates electricity from sunlight that falls on the earth. It can be used just about anywhere-in large buildings, in factories, and in residential homes. Nowadays we must think on a worldwide scale about such issues as dealing with global warming and reducing emissions of carbon dioxide. Solar energy, which has few resource limitations and minimal adverse environmental impact, will surely become more and more essential to our lives in the years ahead. Solar Power Generation Systems begin with the solar module. Solar modules capture solar energy and generate direct current (DC) electricity. Inverters (power conditioners) convert DC into AC (alternating current) to run many common appliances and equipment
SOLAR INVERTER:
A Solar inverter or PV inverter is a type of electrical inverter that is made to change the direct current (DC) electricity from a photovoltaic array into alternating current (AC).
The solar inverter is a critical component in a solar energy system. It performs the conversion of the variable DC output of the Photovoltaic (PV) module(s) into a clean sinusoidal 50- or 60 Hz AC current that is then applied directly to the commercial electrical grid or to a local, off-grid electrical network.
These types of Solar Inverters are used only for rural areas, where there is no electricity at all. The same above concept is used, but with more panels and bigger external charge controllers are supplied to handle more currents. As the systems are mainly depending on charging from solar panels.
At the heart of the inverter is a real-time microcontroller. The controller executes the very precise algorithms required to invert the DC voltage generated by the solar module into AC. This controller is programmed to perform the control loops necessary for all the power management functions necessary including DC/DC and DC/AC. The controller also maximizes the power output from the PV through complex algorithms called maximum power point tracking (MPPT). The PV maximum output power is dependent on the operating conditions and varies from moment to moment due to temperature, shading, soilage, cloud cover, and time of day so tracking and adjusting for this maximum power point is a continuous process. For systems with battery energy storage, the controller can control the charging as well as switch over to battery power once the sun sets or cloud cover reduces the PV output power. The controller contains advanced peripherals like high precision PWM outputs and ADCs for implementing control loops. The ADC measures variables, such as the PV output voltage and current, and then adjusts the DC/DC or DC/AC converter by changing the PWM duty cycle
The number of panels depends on various backup requirements and also the customers paying capacities. Ideally in the case of only solar systems, we have to give the same wattage of panel inputs, as to what the load is. In case of hybrid systems we can reduce the panels to half or 1/4th of the total power required (as the charging is also done through main electricity line ( Apart from solar panels).
SOLAR HYBRID INVERTER:
A purely solar power solution for general lighting load is very expensive as far as initial investment is concerned. Also, due to frequent power failure, a regular battery backup UPS / INVERTER barely gets time to charge the battery from mains. The Hybrid Version combines solar energy and mains utility to give an excellent solution by providing the best of both worlds.
Our hybrid solar inverters are designed with extreme flexibility so that you can add panels as and when required in the future to increase the percentage sharing of solar power.
You are assured of uninterrupted supply, even during frequent and long power failures. More importantly, you get to use Green Power and in turn help maintain a pollution-free environment.
The Solar Inverter comes with the choice of charging of batteries by both solar as well as mains utility (Hybrid Solar Inverter), with automatic change over from mains to battery and from battery to mains like a regular inverter. It employs an inverter circuitry, two-level battery charging from mains, Solar Charge Controller ie. MPPT and fast change over mechanism during power failure and resumption.
Solar Hybrid UPS / Inverter/ Home UPS
Solar Hybrid UPS / Inverter/ Home UPS
Mahatma Gandhi once said the soul of India lives in its villages . But the villages in India are still reeling under heavy load shedding and acute power shortage. Keeping this in mind True Power has introduced Solar Hybrid Home UPS for optimum performance, ensuring availability of electricity even during long and frequent power cuts. True Power Solar Hybrid UPS work as follows:
When solar power & grid power both are available, it takes full 12 amp charging current from solar panel to charge the battery depending on solar panal current. In case solar current available is less than 12 amp then its takes balance power from the mains.
Only when there is no solar power, then it will take 12 amp from the mains. However in case of power cut during day time when solar is present the 12 amp load will be taken the solar panel and the rest of the load will run on battery, thereby increasing the backup time.
So can you can save some money on your electric bill maximizing the uses of solar power.
If installed as additional Inverter for home, solar power would be very helpful during frequent power cuts where minimum required power for charging the battery is not available from grid.
Generally grid power is available in night to domestic user & power is absent during peak hour. Solar Hybrid UPS battery remains charged during the night from grid power for early morning usage and during day time it is charged through solar for evening time usage, So True Power Solar Hybrid UPS takes care of battery charging problems and make sure you enjoy peace of mind.
