Things You Need For Your Grid
We live in exciting times where power is available across most of the country to help you carry on with your day to day life easily. From homes and offices to shops and factories and hotels, power has revolutionized the way life is lived and enjoyed. And thanks to renewable energy sources like the sun, it is no longer necessary to burn fossil fuels to generate electricity and harm the environment. Problems of load-shedding or power cuts are easily handled too,with the help of advanced power backup systems.
Why go solar for power?Driven by rapidly escalating power tariffs, and a pressure to shift away from fossil-fuel based energy, there are cleaner and cheaper alternatives now available to meet the power needs of your household. Solar power is driving the change, especially in India, with its abundant sunshine.
The diagram below represents an optimal solution, with the added peace-of-mind of a back-up. For discussion we take a household system as an example.The principle applies equally to commercial/industrial use as well.
A close look at grid-tied solar systemThis grid-tied system connects your household solar system to the power supply grid. Your panels feed electricity into the grid, and the utility credits your account for the power you generated. You can draw on that power whenever you need it . This system enjoys two benefits.
Two: More importantly, the grid acts as a backup when your panels stop generating electricity for whatever reason.

Takeaway: Summer Exports Offset High Winter Usage
A home with grid-tied solar panels will generate lots of excess solar power during the summer. The homeowner can then carry these credits over and use them during the winter when their grid imports are higher than solar power exports.
In other words, the high solar generation over the summer serve to cancel out the relatively high imports of the winter. In fact, with a properly designed system, a home with grid-tied solar panels can even end up with zero net electricity usage charges for the year.

Smart Solar Holds A Lot Of Promise
The introduction of hybrid solar systems has opened up for many interesting innovations. New inverters let homeowners take advantage of changes in the utility electricity rates throughout the day.
Solar panels happen to output the most electrical power at noon not long before the price of electricity peaks. Your home and electrical vehicle can be programmed to consume power during off-peak hours .
Consequently, you can temporarily store whatever excess electricity your solar panels in batteries, and put it on the utility grid when you are paid the most for every kWh.
Smart solar holds a lot of promise. The concept will become increasingly important as we transition towards the smart grid in the coming years.

Selecting Charge Wire And Fuse
Lastly, we must select the wire from the charge controller to the battery. The charge controller will put a maximum of 20 amps into the battery, so we need a wire that can handle 20Amps.
To calculate the minimum fuse size, we have to calculate the current that goes through the wire, which is 20amps. We multiply that by the 1,25 safety factor to become 25Amps. The wire can be 12 gauge, but since there is no 25Amp fuse, we have to use 10 gauge.
The maximum fuse for a 10 gauge cable is 35A. Now we need to choose a fuse that is in between these two. We will use a 30A fuse. The maximum length will be 6ft. Keep this distance as short as possible.
Standalone Emergency Battery Backup Power Systems
Whether or not you have solar power at home, having a source of emergency power is a great idea. Our portable power banks are an easy way to acheive that. Completely independent of your grid-tied solar system, this method of battery backup doesn’t automatically activate it’s an emergency power source you can plug your critical appliances into during a power outage. While energy capacities are lower than you’d usually have with a true grid-tied solar system with battery backup, a standalone home battery storage solution like these are less expensive and portable – great for true emergencies.

Youre Not Eligible For Net Metering
Solar-plus-storage systems that include a battery are particularly beneficial if your utility doesnt have a good policy for compensating homeowners who generate excess solar electricity. For example, some utilities dont have retail rate net metering for solar, which means you wont receive a full bill credit for solar electricity that you send back to the grid. If you live in California, net metering 2.0 means that new solar homeowners will be enrolled in time-of-use rates with their utility. As a result, the credit you receive for your solar electricity will vary depending on the time of day electricity sent back to the grid during peak hours generally results in higher value credits. In both of these cases, you can benefit from storing your excess solar energy at home even though youre still connected to the grid.
Should I Install A Grid
Some people want to just purchase the equipment and install the panels themselves. For some, this works out well. Especially those with prior experience with electronics, solar, roofing, and/or construction.
Were obviously biased towards having professionals install your solar panels, and batteries for you. For arguments sake, here are some of the benefits and drawbacks of a DIY solar installation.

What Is Battery Depth Of Discharge
It shows the amount of power that can be drawn from the battery without causing damage.
For solar energy storage, two basic types of battery are used:
Deep-cycle lead-acid batteries can be discharged up to 80% but 50% is normally advised to preserve the longest life.
LioFeP04 batteries can be discharge up to 95%, so this DoD represents a greater value for money.
How Do I Integrate A Battery Backup With A Grid
One of the most common questions asked by customers is how to integrate a battery backup solution with an existing grid-tie system. As designed and required by law, grid-tie systems shutdown during a grid power outage. To get a better understanding as to why that happens, read this article for a more detailed explanation on the subject. The main reason is to make sure solar panels are not back-feeding power into the grid while line workers are attempting to make repairs. With those details being known, customers want to maintain some level of power during a grid-outage for powering essential appliances or critical loads. Resolving that issue requires integrating a battery backup alongside your grid-tie system that does not feed power back into the grid.
In closing, AC Coupling offers a fail-safe option to power critical appliances like freezers and water pumps if grid power goes down and allows the system to back-feed the grid when grid power is active while ensuring your battery bank is fully charged.

Connected To The Grid: Meters Monitoring & Net Metering
Most electric meters measure electricity moving both into and out of your home or business. Generally, we are taking electricity from the electric grid for our needs. The meter runs forward as it counts up the kilowatt hours we have consumed. But if you generate electricity with a grid-tied PV system and you make more electricity than you need, net metering allows this excess electricity to run the other way through the meter and back into the electric grid.
For example, on a sunny summer day a PV system might produce more electricity than needed at the time. Conversely, in the evening when everyone is home, electricity needs may exceed the output of the system.
If you put 10 kilowatt-hours of excess electricity into the electric grid during the day, net metering allows you to take 10 kWh of electricity out of the grid later and pay nothing extra for this electricity. In effect, you are allowed to bank these 10 kWh and use them later to offset your need to buy this electricity.
Your inverter probably has a display showing cumulative generation, but if you change inverters, you would lose the count to that point. So the best way to monitor the output of your solar electric system is a dedicated meter at the inverter.

Ac And Dc Coupling Combined
Most modern interactive inverter-chargersand such as the Selectronic SP PRO, SMA Sunny Island and Victron Multiplus, can function in both AC and DC-coupled configurations. This offers the best of both worlds and provides backup DC battery charging in the event of an AC shutdown.
Combination AC and DC Coupled system – Can be configured as Grid-interactive or Off-grid with generator
If there is an inverter shutdown in a remote location due to low battery voltage or low SOC, the DC-coupled solar charge controllers will continue to function and recharge the battery system, which preserves the battery life and can restart the system if configured correctly. This is a more fail-safe setup, unlike pure AC-coupled systems, which are sometimes unable to be automatically or remotely restarted unless a backup generator or AC source is functioning.

A combined AC and DC-coupled off-grid solar system – Selectronic SP PRO AC coupled to a Kaco solar inverter. The lead-acid battery bank is also charged with two DC coupled Victron MPPT solar controllers.
Which Is Better Grid Tie Or Hybrid
The best choice for you depends on your individual needs and requirements. Grid-tie solar systems are designed to connect to the utility grid and feed excess electricity generated from your solar panels back into the grid.
This means that you dont need any batteries and will usually get credit from your utility provider for the extra electricity generated. However, the main drawback of a grid-tie system is that it wont generate electricity during a power outage.
Hybrid systems are more complex and expensive than grid-tie systems, but they have the added benefit of storing electricity in batteries for times when the grid is down. This makes them ideal for people who live in areas with unreliable grid power, such as remote and rural locations.
The ultimate decision of which is better, grid-tie or hybrid, really depends on your individual needs. If you live in an area with reliable grid power, a grid-tie system may be ideal since it could save you money on your energy bill by selling back excess energy you generate.
If you are looking for a backup of power in case the grid goes down, then a hybrid system might be better for you. Ultimately, it is important to look into both options and see which meets your individual needs.

Why Would You Choose A Grid
Off-grid solar technology is becoming more advanced every year, and a growing number of companies are manufacturing solar batteries for home. If you install battery storage along with your PV system, you can store excess solar electricity when its produced and then use it as needed later. Theoretically, this means that you can completely sever your connection with your electricity utility. In practice, it often makes more sense to stay grid-tied, particularly if you live in an area with significant climate variation.
Most of the solar batteries for home use available today, like the Tesla Powerwall, are designed to store solar energy generated during the day for your home to use at night. This can help you reduce your reliance on utility electricity by storing your excess solar power at home instead of feeding it back into the grid.
The trickier proposition is generating and storing enough extra solar electricity in the summer when solar power generation is highest to cover your future needs in the winter, when solar potential is at its lowest. According to 2021 EnergySage Marketplace data, the average solar shopper offsets approximately 97 percent of their annual electricity use with solar a significant amount, but not enough to go truly off the grid.

High Voltage Vs Low Voltage Batteries
The new generation ‘high voltage’ batteries operate in the range of 200-500V DC as opposed to the traditional 48V battery systems. This offers several advantages, including lower cable losses and improved efficiency as the solar array typically operates at 300-600V which is very similar to the battery voltage. Higher voltage batteries and compatible hybrid inverters use lithium battery systems operating between 120-500V, rather than 48V. Higher voltage batteries can be configured in two different ways:
DC-coupled between the solar array and inverter.
DC-coupled directly to a compatible hybrid inverter .
Since most solar arrays operate at high voltages around 300-600V, high voltage batteries use efficient DC-DC converters with very low losses. The first generation Tesla Powerwall was the first 400V battery available and was mated to the popular SolarEdge Storedge hybrid inverter.
The LG chem RESUH and BYD HVM series batteries are some of the most popular HV 400V battery systems available, being compatible with many hybrid inverters including SolarEdge StorEdge, SMA sunny boy storage and Fronius Gen24.
