Solar inverter hookup
The market for home energy storage options like the Tesla Powerwall has taken off in recent years, and costs are falling quickly. Many homeowners and businesses are thinking about adding a battery backup to their solar panel system. The benefits of a home battery can be big, especially if you have solar: If you have time-of-use TOU rates for your electricity or pay monthly demand charges, you can even save money by using power from your battery when rates are high. Shoppers using the EnergySage Solar Marketplace to compare solar quotes often ask a range of questions when considering the addition of battery storage. Below, you can find answers to the top four most frequently asked questions about retrofitting a solar panel system with a battery.
Wiring solar panels: Do you wire solar panels in series or parallel?
I f you enjoy boondocking for days at a time in sunny locations like the Southwest , then a permanently installed RV solar system could provide the energy independence you're looking for. However, you won't get a return on your solar investment if you stay primarily in full-hookup RV parks and campgrounds. You might instead keep a portable solar panel kit on-hand for those occasional boondocking or no-hookup situations.
Still need answers? Here are answers to common questions and misconceptions new RV owners have about solar. My wife and I enjoy the freedom of traveling and camping without hookups and have been powering our RV from solar for many years. We don't use power-hungry appliances for extended periods and don't have a residential refrigerator. Our mid-sized off-grid solar system and battery bank provides enough energy to power our RV indefinitely as long as there's sun.
Our large AGM battery bank has enough reserve capacity to power our RV for at least a couple days without being recharged. In fact, we rarely plug in anymore. Since you're reading this, I'll assume you're thinking of adding solar to your RV and still have unanswered questions. So keep reading, this article is for you. The only time you will benefit from solar is when your RV is disconnected from shore power. There is no reason to have solar on your RV if you primarily stay in full-hookup RV parks.
If you prefer to camp in areas where there are no power hookups , then solar may be worth considering. If occaisional boondocking is your thing, then a portable solar panel kit may be all you need to benefit from solar and avoid a potentially costly permanent installation. When not on shore power or generator, your batteries become your primary source for DC power.
Onboard or portable generators do a good job powering your RV but require a steady supply of gasoline to run. The noise levels can also disturb nearby campers. A solar charging system requires no gas, makes no sound and can charge your batteries for hours and hours unattended as long as the sun is shining.
In fact the sole purpose of solar panels on an RV is for battery charging. A common misconception is that solar panels will power your RV. While this is not entirely false, it is a mistake to think of solar panels in that capacity. As I've stated the primary purpose for solar panels on an RV is to recharge your battery bank when your RV is not connected to shore power or powered by generator.
Solar charging systems are not standard equipment on most RVs as they only benefit RVers who camp for days at a time in areas where there are no power hookups. So solar remains a custom option like having a satellite dish installed. Many RV manufacturers will pre-wire for solar panels to simplify the process of running cable from the roof into the RV. In a well designed RV solar charging system however, there are many factors unique to each installation that determine cable type, thickness and length.
For this reason most " wired for solar " dealer configurations fall short. Here's why the "real cost" can get this high. Many new RV owners love the idea of free camping without hookups and using solar panels to power their RV. What they really want is a battery powered off-grid electrical system that powers their RV day and night while camping in those amazing locations.
Let's face it, solar energy is pretty cool. Which is why many new RV owners jump directly into pricing solar panels online trying to figure out " How many solar panels do I need to power my RV? In reality, there are several components needed to take your RV off-the-grid with solar. Solar panels are just one piece of the puzzle.
You should really start with your battery bank. Also keep in mind that the price and features available for each component vary considerably. The list goes on. Then add the expense to design a custom system and install it on your RV. You can cut labor costs if you're a qualified do-it-yourselfer. Your individual power needs will ultimately determine the size, cost and components you'll need.
There's no one-size-fits-all solution. Here are some ball-park estimates for three common off-grid configurations not including labor:. This setup can power basic small electronics like lights, laptops, mobile hotspot, TVs, and cell phone booster. This setup can power small electronics plus periodic use of a microwave oven, coffee maker, hair dryer, electric blanket. Over time you will figure out what your camping preferences and limitations are.
You'll be in a better position to decide whether an investment in solar is something you'll benefit from. Seasoned RV owners, on the other hand, will probably know whether solar is a necessary feature when purchasing a new RV. If you feel camping off-the-grid is something you're interested in, then I encourage you to try it out first before making a significant investment in solar or generators.
Consider starting out with a portable solar panel kit. There is no permanent installation required and they provide plenty of power to keep your batteries charged. Just store the portable panel when you don't need it. You could even create your own portable solar battery charger. Building your own is a fun way to learn the basics of solar. Here's a simple project video showing how to build a basic portable solar charger.
When we first started RVing, we primarly stayed in RV parks. We didn't even consider locations that did not have full-hookup sites. Over the years our preferences have changed. We still stay at RV parks periodically, but prefer to seek out more scenic locations. At first my wife was a bit uncomfortable with the idea of being off-the-grid and having to sacrifice too many creature comforts.
These days we don't have to sacrifice much while off-the-grid and she is totally on-board with boondocking without hookups. There are many beautiful campgrounds located on public, National Park, or State owned land. Camping at these campgrounds is inexpensive and often free. However, what you gain in beautiful scenery and solitude you lose in amenities.
Having a totally self-contained and self-sufficient RV prevents us from having to sacrifice much. In fact we can function quite well off-the-grid without campsite amenities. We have more options for camping, are more spontaneous, and even save money by not relying on expensive RV parks. Don't ditch your generator for solar. You'll need to put back the power you took out of your batteries, even on those days when exposure to the sun is limited. This is when a auxilliary generator comes in handy.
A generator can also power an air conditioner, heater or other power hungry appliance when you're battery bank and inverter can't. If you don't have a large on-board generator, a small portable generator can provide enough power to recharge your batteries and run a few small appliances. There are cases when some have abandoned their generator completely and made the necessary adjustments for living solely off of solar.
As for us, we have less of a need for a generator since installing solar and a large battery bank. Solar is our primary source of battery charging, but we still like the security of having a generator available if we need it. We also boondock only in locations with a moderate climate. Extremely hot and humid climates are generally not optimal for boondocking with solar.
The solar panels on your RV are used mainly for battery charging. Therefore, the amount of power electrical load you can draw is determined primarily by the capacity of your battery bank and inverter, and NOT by the amount of solar on your roof. This is a common misconception people have when they ask " how many solar panels to I need to run my whatever?
In some cases small coffee makers, low power microwave ovens, toasters, and low power hair dryers can be used for very short periods depending on your battery's state of charge and size of your inverter. Power hungry components like those will rapidly drain your RV batteries. For this reason, most RVers who rely on solar relocate throughout the year to sunny locations that have moderate climates.
Is it possible to run an air conditioner off of an RV battery bank? Yes it is. Is it a practical solution? No, not at this time. As the price of off-grid lithium battery systems continue to fall, we may start seeing lower powered AC units for off-grid RVs. For now, I'd stick with a good fan. If your RV has a residential refrigerator that only runs on electricity, you'll need a large lithium battery bank and solar array. The best way to figure out what your needs are is to just go do some dry camping for a few days while measuring your power usage.
To get an accurate indication of your state of charge, you will need a battery monitoring system. Without one, you'll simply be guessing and probably guessing wrong. The battery voltage or level gauge your RV came with will not give you an accurate measure of your battery state-of-charge how much reserve power available. So this is an essential first step to figuring out how much power you need while out camping. Take your RV dry camping and watch that battery monitor.
You won't need solar panels for this experiment. Just use your RV and see how long it takes to get down to 50 percent of available capacity if using lead acid batteries.
AC WIRING HOOKUP TO YOUR RV ELECTRICAL SYSTEM. Inverter/chargers have a unique feature that allows automatic operation when wired into the RV's. Our solar experts will help guide your DIY home solar panel installation. and electrical hookup, everything you need to conquer your DIY solar project . mounting and installing the solar panels, inverter(s), safety disconnects, and so on.
Mixing solar panels of various voltage or wattage, or produced by different manufacturers, is a frequently asked question by most DIYers. When you intend to wire two panels produced by different vendors, the vendors are not the problem. The problem is in different electrical characteristics of the panels, together with different performance degradation.
How to Connect Solar Panels Together Connecting solar panels together is a simple and effective way of increasing your solar power capabilities.
While the technology behind solar energy seems complex, when broken down, how solar power works is easy to understand. Whenever the sun shines and even in overcast weather , the solar cells generate electricity.
AC Wiring Hookup to RV System
So you are producing energy with a windmill or solar panels, now how can you use this to power your light bulbs? The technology behind renewable energy systems is confusing for those new to the field. Your renewable energy sources can be grid connected, or off-grid, with battery backup in case the grid goes out, or without, and that is just the beginning. This section intends to give an overview of the basics involved in connecting renewable energy sources together, and to the grid. There are several sections that are increasingly more complex:.

What does a power inverter do, and what can I use one for? A power inverter changes DC power from a battery into conventional AC power that you can use to operate all kinds of devices You just connect the inverter to a battery, and plug your AC devices into the inverter The inverter draws its power from a 12 Volt battery preferably deep-cycle , or several batteries wired in parallel. The battery will need to be recharged as the power is drawn out of it by the inverter. The battery can be recharged by running the automobile motor, or a gas generator, solar panels, or wind. Or you can use a battery charger plugged into an AC outlet to recharge the battery. A very simple way to use an inverter for emergency power such as during a power outage , is to use a car battery with the vehicle running , and an extension cord running into the house, where you can then plug in electrical appliances. We carry many different sizes, and several brands of power inverters.
This instructable will show you everything you need to put together a pretty good sized electric solar panel system.
As a homeowner who is just learning about solar energy options, it is easy to get confused with all the technical terms you might read or hear about. Your installer is likely to mention different ways that arrays of solar panels are wired. And your first thought might be that it does not matter how they are wired.

What are the benefits of grid-connected solar panels vs. Deciding whether or not to grid-tie your solar panels is usually pretty straightforward — the clear-cut benefits of being grid-tied appeals to the majority of homeowners. There are, however, some people that choose to live off the grid. What would be the best in your situation? Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept — a solar system that is connected to the utility power grid. A grid-connection will allow you to save more money with solar panels through better efficiency rates, net metering, plus lower equipment and installation costs: Batteries, and other stand-alone equipment, are required for a fully functional off-grid solar system and add to costs as well as maintenance. Grid-tied solar systems are therefore generally cheaper and simpler to install. Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries. Net metering or feed-in tariff schemes in some countries play an important role in how solar power is incentivized.
