Solar Grid-Tie Packages

PV on-grid rooftop solar power system is one of the most popularly used solar solutions for houses and commercial establishments. Grid-tie solar , also knows as on-grid, works in connection with the main grid. It offers the advantage of running load directly through solar and selling excess solar power back to electricity company by feeding the grid.

Su-Kam's grid-tie inverters have high efficiency of more than 97%, guarantee reliability, and are meant for India's harsh weather conditions. Packed with superb features they let you make ROI in just 3 years – yes, you can recover the cost of the system in only 3 years.

Rooftop solar panels convert energy from coming from sun into electric energy, Direct Current (DC), which is sent to inverter.

The inverter then converts DC it into Alternating Current (AC) because it is not possible to use DC directly – all our electronics need AC supply. Grid-tie inverter also regulates the voltage. The PV cells may make excessive DC but that can’t be fed into your main supply as it may be too much to handle. Inverter regulates the voltage of DC that it gives to the main supply.

Inverter converts DC into usable AC and feeds this to the main supply.

Now that it is in your main supply, any electrical appliance can be plugged in to enjoy free, clean and green solar energy.

When solar power is being converted into AC electricity and powering connected load, the electricity meter stops – meaning you don't take anything from the electricity company. If there is a surplus of solar power after running all the load, it can be fed back to the grid for a price of Rs. 6-9 per unit depending on the net metering policy of the state.

In the absence of solar such as in the evening or when there are thick clouds, the grid-tie inverter runs the load through main grid supply.

Amazing Features of Su-Kam's PV Grid Tie Inverters:

  1. Equipped with Latest MPPT Technology Which Guarantees 97% Efficiency :

    Our grid-tie inverters run on most advanced Maximum Power Point Tracking Technology. It boosts the incoming current from Solar. For example, if the solar panels are making 6 or 7amps of current then MPPT enhances it to 10 or 11 amps – you get 30% more electricity from the exiting solar panels – similar to having an extra solar panel.

  2. Wide Operating Range:

    MPPT charge controller inside Su-Kam's grid-tie inverter has a very broad operating voltage (150v to 500v for 1.5k to 5kw and 200v to 850v for 10k to 50kw) which means that they are able to make the solar power system run even on cloudy days or during early mornings and late afternoons.

    No matter how little the sunshine is, our grid-tie inverter will work hard to get maximum out of it. Inverters that don't have a wide operating voltage may not work during inadequate sunshine.

  3. Make Even More Solar Power Thanks to Dual MPPT:

    With our dual MPPT enabled grid-tie inverters you can use more than one side of your rooftop to produce maximum solar energy. You can split your solar panels over two different areas of your rooftop – you can install solar panels in both east and west side. Dual MPPT will make the best possible use of power generated from both the sides.

    For example, if one set of solar panels gets damaged or comes under shade then dual MPPT will still provide power from the other, good (unshaded side) set of solar panels. This also means that you can generate maximum solar power from east-facing panels in the morning and west-facing panels in the late afternoons.

    Without dual MPPT you would have to spend a lot of money on installing a separate grid-tie inverter.

    Dual MPPT also supports unbalanced arrays i.e. on a 16 panel system you can have 7 panels west facing and 9 east-facing. In this way you can best utilize the sunniest side for more solar power generation.

  4. Shade Tolerant MPPT Algorithm:

    Due to features such as Dual MPP tracking and wide operating voltage, our PV grid-tie inverters continue to work even during periods of partial shading due to clouds or dust.

    However, no solar panels or MPPT are tolerant to complete shading so Su-Kam's team will install the panels in such a way that they get maximum sun.

  5. Meant for Tough Indian Conditions:

    Su-Kam's grid-tie inverters are designed to stay tough during extreme weather conditions in India such as heavy rains, storms, and heat. They have a rating of IP65 which means that they can handle dust and heavy rains. They can function equally well when temperature hits more than 50 degrees or when it drops below 0 degrees Celsius.

    As grid-tie inverters are installed outside, it becomes very important that they should withstand fluctuations in weather.

  6. Hi-Frequency and Transformer-less Design:

    Due to being transformer-less, PV grid tie inverters have a high frequency which leads to high efficiency of 97%. It also makes them light-weight and easy to install

  7. LCD Screen to Monitor Performance:

    The screen on inverter help you see the performance of inverter such as DC input voltage, output voltage and current, units of electricity being made etc. It also alarms the user in case of any problem.

  8. Minimum Maintenance:

    The ability to function in even extreme weather conditions and absence of moving parts (such as fans) means that it is maintenance-free – plug and forget!

  9. Easy to Install:

    It is a transformer-less compact unit that can be easily mounted. It also has plug and play AC and DC connectors which makes installation easy.

  10. Monitoring from Anywhere in the World:

    Our grid-tie inverters can be connected to Su-Kam's PV monitoring kit through which you can access all information related to the functioning of your solar power system such as DC input voltage, output voltage and current, units of electricity being made etc. You can access this online no matter which part of the country you are in. Offline monitoring is also possible. It records data of up to 25 years and can be used with as many as 64 grid-tie inverters.

  11. Make Money with Net Metering:

    Grid-tie inverters are capable of feeding excess solar power generated back to the grid. Depending on the net-meting policy, it is possible to make money by selling energy to your electricity company.

Who Should Install Grid-Tie System?

  • If you have a large shadow-free area on your terrace and you do not experience many power cuts you should install grid-tie system as you will be making huge saving on your electricity bill. Our customers in Chennai who have installed grid-tie system in their houses get electricity bill of as low as Rs. 300 per month. [Read More]
  • If you live in a state that offers attractive net-metering policy then on-grid solar is an obvious choice. For example, in Bangalore the state offers a high rate of Rs. 9.41 per unit.
  • If you are a commercial establishment then solar will ease your soaring electricity bill. Businesses usually pay a higher rate to electricity companies so going solar will be a good financial decision.
  • School, college or any business whose operating hours are during the day, can immensely benefit from grid-tie installation as they will be paying NOTHING to the electricity company. They will be able to run all their load directly though solar during the day.
