Grid Tie with Battery Back-up Systems

The grid-tied system with battery backup provides for an energy-efficient home and business application.

Grid tied systems with battery backup has dual benefit of selling back excess power to the grid while have the use of backup batteries power for use if the grid fails.

Although batteries will add to the cost of system initially and maintenance to a grid-tied photovoltaic system, the peace of mind gained by knowing all or your essential loads will continue running when grid power is “down” may make it worth the extra startup costs.

This system is ideal for both residential and commercial purposes.

  • A battery back-up system acts similar to a generator
  • Can sustain your household for a period of time without drawing energy from the grid
  • Power is maintained if the grid goes down
  • These systems tend to be more costly due to the added battery hardware
  • Grid – connectivity €“ excellent investment as you are able to sell back power to the utility provider. You may be able to earn money every month.
  • Flexibility – systems allow expansion so you may start small and increase panel numbers and battery bank overtime
  • Batteries will require maintenance
  • Automatic conversion from solar power to utility power and vice versa
  • Possibility of no electric bills and no blackouts
  • Low maintenance costs
  • Durability
  • Reduce your dependency on foreign oil

When the sun is shining, the solar panels generate power, which reduces the consumption of electricity from the grid and cuts electric bills accordingly. If this power is not enough for your home, the required balance is automatically provided by the batteries before hitting the grid if needs require.

If the solar panel system generates more electricity than your house is using, it will feed the excess back to the grid after the batteries are fully charged, and may spin your electric meter backwards. Under normal conditions, a small portion of the energy is also used to keep the storage batteries charged.

Grid-tie with battery back-up photovoltaic systems is connected with the existing power grid and sell excessive electricity back to the utility with a plan known as Net billing or Metering. This means that at times when you are not using all of the electricity being produced by your system, your meter will spin backwards selling the electricity back to the public electricity grid at retail rate allowing the system owner to realize significant saving on their energy bills and faster returns on their investments.

Some battery facts

If wet cell batteries are selected, they need to be periodically checked for fluids. Sealed batteries do not need any maintenance but may not last as long as the wet cell types.

Our Carisol Grid Tie with Battery Back-up Solar Power Systems is available in following standard sizes but we can custom manufactured to any required size.

These are complete turn-key Grid-Tie with Battery Back-up solar system packages that allow for easy expansion at a later time by adding just a single panel at a time and are perfect to roll your meter backwards selling power to the utility grid.

Each Carisol Solar Power System is designed for tropical countries, adjustment to systems designs will be necessary for colder regions.

This system comes with standard PV roof mounting therefore depending on your project location, environmental issues, and roof configuration you may need extra parts for your mounting systems. Please consult one of our sales engineers for additional balance of systems components that you might require.

Q. Is my home or business suitable for solar power?

A. All homes or business is suitable for solar power some might need extra time on the job for the installer base on roofing type.

Q. What size system will I need for my home or business solar power?

A. The minimum size system available at Carisol is 1kW (1000watt). That has a potential output capacity of 1000 watts of DC (direct current) electricity. This DC output is sent directly to the inverter which converts the DC power into 220 volt AC (alternating current) power for use in your home, or export to the electrical grid. A 1kW capacity system will generate about 1470 kWh of electricity per year. You will be able to see from your last electricity bill how many kWh you use at each monthly billing period. There should also be a graph that indicates your last twelve months of usage. This should give you some idea of what size you will require.

Q. What kind of warranty comes with the system?

A. Each of the components comes with different manufactures warranties and conditions ranging from 5 to 25 years. If there are any faults with any component of the installation within the first 12 months, Carisol will arrange for an exchange or repair at no cost to you. The manufacturer warranties for the components will be outlined on your system description and diagram document that will be provided with your quote and agreement.

Q. Does my roof have to have a slope?

A. No as roofing mounts can create any angle requirement needed for system tilt angle.

Q. What if the panels are damaged by a natural event such as hail?

A. TUV testing and certification of our solar panels requires that a 1inch solid ice ball be fired at 50mph straight at the panel without breaking the glass or creating damages to the solar cells however there are those are rare cases where the stones that are bigger can and will break the glass. PV panels can be covered under your home insurance policy so we recommend call to your insurer if needed so you can add your solar power system to your home policy.

Q. How much will I save?

A. An entry level 1000 watt grid connected solar system will save an household using 300kWh per month around an average of 40% a year on the power bill.

Q. Will the solar system gives me power at nights?

A. Solar systems needs the sun to operate so at nights you will be taking power form the grid , however if you had produce more than you had use during the days then this will offset the power you take from the utility at nights.

Q. How long will the panels last?

A. A good quality solar panel will last a lifetime and comes with a 25yrs output warranty, it€™s important to look for the TUV quality certification symbol on product or brochure before purchasing.
