Hi and welcome to FYI , a new informational tutorial series from Wholesale Solar. My name is Josh Roelofs and today we're going to talk about gridtied inverter system options. Your first option is the SMA Sunny Boy inverter. The SMA Sunny Boy is the only gridtied inverter which includes the secure power supply which can provide a minimal amount of backup power during a power outage provided the sun is shining. It's a USmade product, highly reliable, it's also your lowestcost option. These inverters are designed to work with solar arrays that are positioned in direct sunlight.
If you have shade from a nearby obstruction, such as trees, buildings or something else, you would want to consider one of our other gridtied inverter options such as the SolarEdge. SolarEdge is a highly efficient inverter system because there's a power optimizer on each solar panel. It can help mitigate the impact of shade on a portion of your array SolarEdge is the only gridtied inverter which includes builtin monitoring at no additional cost, giving you the ability to remotely view system performance from any internetconnected device. This system includes the Safe DC Voltage.
Feature which means you're not working with high DC voltage when you're wiring optimizers together. This inverter system is also expandable. If you want to add to your array at a later date you can plug in more optimizers to your existing group of optimizers to expand your system. SolarEdge offers the best balance between price and features out of any of the gridtied inverter options we sell. It's suitable for residential or large commercial systems. In some cases our customers will require even more flexibility from their gridtied inverter system.
Which is when we recommend the Enphase microinverter. The Enphase microinverter is a completely modular system where there's one inverter for every solar panel, so it's expandable. It can help mitigate shade but this system is really ideal for people who are starting out small and expanding later. There's no minimum requirement you could literally start with one panel and one micro inverter and get your system up and running This system uses ac wiring instead of DC voltage so it's considered to be safer and easier to install especially for the DIY.
Installer. The microinverters have a lot of great features including the longest industry warranty at 25 years, advanced monitoring is available with the Envoy hardware, it's also the most flexible system if you need several groups and panels at different parts of the roof or different groups of panel facing different directions. Enphase is going to offer you the highest level of flexibility from a gridtied inverter system. So these are three gridtied inverter options available. If you have any questions or need more information please give us a call.
FYI Four Main Types of Solar Systems
Hi, and welcome to FYI , a new informational tutorial series from Wholesale Solar. My name is Josh Roelofs and today we're going to talk about the different types of solar systems available. The first and most common option for a PV system is a gridtied power system in which the solar panels and your inverter is tied into the household electrical system and it simply offsets your energy usage. A gridtied system offers the lowest overall system cost, fastest return on investment. It saves money on energy expense by sending energy back into the grid and turning your.
Meter backwards. It's ideally suited for people who are trying to save money on energy costs. The drawback to a gridtied system is that it does not offer protection from power outages. When the power goes out, your gridtied system is going to shut down. So if you're in an area where the power is unreliable, or you want to protect against power outages, you'll want to consider one of our other options. A gridtied with battery backup system is going to offer the best and most comprehensive features for most people. It can provide backup power to your appliances during a power outage.
It can also turn back your meter to offset energy costs. This system is especially suitable for people who live in an area where the power is unreliable or people with critical equipment like computers, or a pump, or something you need to run during a power outage. Like coffee. Gridtied with battery backup is going to offer a combination between cost savings and independence from the power grid. An offgrid system is completely independent from the power grid. It's especially great for areas where there's no grid power available, or where it's incredibly expensive to bring.
In the power grid. You can literally buy land anywhere and install your own power system. This offers the highest level of independence for people who are seeking selfsufficiency. However, there's a price for that independence. The batteries are going to wear out quicker because they're being cycled every day. Typically they'll be replaced every 510 years, depending on the system. BUT. did I mention total independence A gridassist system works similar to and uses the same equipment as an offgrid system. Solar panels recharge your batteries and your appliances run off the battery system.
The difference is A gridassisted system can use the power grid as a backup power source. The grid will turn on automatically when the batteries are low, because it's nighttime, or because there's not enough solar power to support your appliances. This will save you some money on your energy bill, especially if you're in an area where they charge higher rates during the day based on TimeofUse Metering. These are your 4 main system options available from Wholesale Solar. If you have questions or need more information, feel free to check out our website or give.

SolaX X Series Solar Inverters
Every Solax inverter begins with the highest quality components. Over 90 come from longestablished manufacturers in Germany, Japan, and the U.S. We select only the most reliable components, with a focus on high efficiency and longevity. For example, an LEM current sensor is used to collect highprecision data. Its high sensitivity, low temperaturedrift and superior antijamming ability make it the best choice available. Our IGBT's come from Infineon, a worldleading semiconductor manufacturer, and number 1 in providing efficient and reliable components for solar applications. And our dualCPUs both come from Renesas, builders of some of the most reliable CPUs.
On the market. The two CPUs work as a redundantready system, which increases efficiency and provides failsafe mechanisms for safety. Designing the inverter to use these highquality components means keeping a constant eye on heat management and developing unique heat dissipation technologies, something Solax is proud of having achieved. A large heat sink is exposed on the exterior while maintaining direct internal contact with multiple heat generating components. This eliminates the need for noisy fans while ensuring effective and efficient thermal management throughout the device. Large conductors, a typically common source of heat buildup, are uniquely designed to.
Operate from inside an aluminium container that is filled with insulative glue. Encasing these components in this way results in high levels of conductivity which significantly improves cooling within the device. In addition, high heat generating MOSFET's have custombuilt auxiliary heat sinks directly attached. These formfitting heat sinks further reduce internal heat, increasing both the efficiency of the component and its operating lifespan. Solax is the one of the rare inverter producing companies that controls the entire production of our components. Rather than relying on 3rd party SMT facilities, Solax constructed.
One and builds our PCBA boards inhouse one of the very few inverter manufacturers who do this globally. Controlling everything gives us complete quality control AND reduces your cost. Every inverter goes through a rigorous 8step quality control process, including Automatic Optic Inspection Testing Single Board test Safety Testing Automatic Testing Equipment Testing Ageing Testing Second Safety testing Second Automatic Test Equipment Testing Vibration Testing And now Your inverter is ready to go. Quieter operation Lower failure rate Longer lifespan The most efficient energy output Solax Inverters The only inverter in its class.
What Type of Electrical Panels Are Good For Solar
What types of electrical panels are good candidates for solar And what are bad candidates for solar Is a question I asked John Shaw project engineer for Bella Energy. Long story short there are panels out there through grand father clause, if any contractor came in and did any type of electrical work, that electrical work could not pass because of the fact that there is a panel there for a particular brand because of law suits and stuff like that, but that is a bit too nit picky. The things I look for when doing a site visit are.
100 amp main service limit the size of the back feed breaker that we use to feed the house there are other ways to integrate a system into the house with line side taps which can be done in a couple of different locations. We are looking for 150 plus amp service with empty breaker spaces at least two that is going to be the best scenario. We can certainly get around anything and everything we run into but it is a question of how much addition time and weather or not we are service upgrade or we might need to ask Xcel for a.
Service upgrade or stuff like that. The easiest way to integrate a system into your home which is what is called a backfeed service breaker onto your service panel some people call a breaker box. If there are a couple of empty spaces we take a special breaker instead of drawing power and sending it to your living room actually takes power from the PV system and puts it on to the bus bar which then is just another source of electrons on those bus bars for all of the other breakers to pull from.
But we are limited in the size of the breaker we can put in there, by the overall service. So for example lets say you have 100 amp service, the biggest breaker we can use to back feed the system is 20 amp breaker That would mean that you could only do about a 2.5 to 3 kilo watt system. If I am not mistaken. 3 sounds about right I would have to do the math to figure it out, I don't have it in my head there are some other.
Ways to get around it too. What the code actually says is that if it is a 100 service that usually means you have a 100 amp bus bar in your service panel and 100 amp main disconnect that means you can only feed the bus bar with 120 of its rating, so it is feed by the main breaker usually 100 percent of its main rating you can have 20 but if the main breaker happens to be an 80 amp breaker on a 100 amp bus bar that is another 40 amps you could add or.
DIY Solar Panel System Cost
The total of the system and materials was $22K. I ended up spending about another $1,800 in permit fees and a structural engineer and $400 for an electrician, several hundred dollars for a guy to come help me out for the two afternoons he spent with me. Xcel Energy gave me $16,538 rebate. Fix cost based on the number of kilowatts you are installing and has nothing to do with how much you pay the permit office or the electrician. My final cost after rebate was $7,237. I started my research in solar probably about a year before I actually installed it went.
And got a couple of bids from some of the local solar people both from contractors that my friends have used as well as just searching the internet and while talking to one of the guys I find of developed a good feeling from him, and I asked the question Would it be possible to do some of the work myself and kind of learn along the way he said Sure I absolutely support the doityourselfer DIY so I said why don't you throw me bids, what it would cost just come home and have solar one day and what it would cost to have.
It done where I do some or all the work myself. And throw them both to me and I said let's try the second one. The guys name is Steve Cross from Sun Spot Solar. I gave him my electric bills and said this is how much I think I need to generate and he said I agree and lets do these types of panels 180 watts each, you will need some where around 19 to 22 we figured out 21 fit pretty well. So I went and got all the permit information from Golden, filled it out. He came by 12.
Hour one day he type all the Xcel application on the internet and I kind of ran the process and when I had a question I would just send him an email and he helped me out. I think in parallel we order the equipment he dropped off in my driveway. Then one of his installers came out and helped me for two afternoons and I pretty much myself put in the whole rack system on the roof and the installer came out and helped me kind of a two man job carrying the panels up, putting the panels down and bracketing them down.
How to Install Solar Panels Wiring Fuses to Solar Panel DC Side
Alright, now we're ready to wire up our fuses and charge controller on the solar panel DC side. We've got our charge controller ready to go, we're just going to slip our BX wire, which I've actually insulated one of the tips, here, so we don't spark our machine. We'll feed that wire through a strainer leaf and put another little strainer leafer, here, on our BX. Tighten that up a bit. So you can see with that little spark there, that we do have power and we should use some.
Kind of fusing in here just so, if something goes wrong and the fuse blows out instead of the electronics. So, we've got a standard car fuse, this one's rated 40 amps at 32 volts. Really, all we need is about a 15 amp fuse, here, but this should give us some measure of protection. We're going to wire this through on the positive side. We've got a fuse holder that matches our fuse, and we'll just strip off a little bit of this insulation here. We'll form a little edge, a crimp, on this so it will loop under our device nicely. Got.
Screw terminals, here, and we're just going to slip that positive wire right under one of our terminals. In a larger installation this will be done in a separate box, but for a small one, this should be fine. Now, we need to run the other side of the positive wire to our charge controller and we need a little piece of wire for that. So now we've got our little jumper wire ready to go, we're going to strip that off and connect it to the other side of our fuse. Demo So.
Installing Solar Panels
Photo voltaic cells are an important focus of our retrofit. The photo voltaic or PV Cells are destined for the garage roof. There is enough space there to accommodate the 1.2 kW array. Current government rebates apply to the installation of the array but rebates are subject to change so you will need to check if you qualify. The panels are mounted on aluminium frames. This is vital to ensure that they are set to the correct angle. In this location it's around 7 degrees. When it is finished we are hoping to generate about 7kwh per day which goes back into the.
Grid. It may even give us some return. The panels are interconnected and the electricity fed through to an inverter. The PV Cells have a life expectancy of more than 25 years and they are virtually maintenance free so you can be assured of getting a good return on your investment. Installing a 1.2 kW array of photovoltaic cells and connecting into the grid is a relatively simple exercise. The finished array looks very neat and in these conditions will be paying its way in no time. Ok, there it is, the photovoltaic's are installed on the roof. They are wired into here, this.
