$4 Solar Battery Charger

Simple Solar Installations A simple solar-panel installation keeps critical gear on a modest cruising sailboat powered up for extended passages. By Green Brett posted May 31st, at The goal was to maximize output with a simple self-managing system that would be robust enough to keep the basic devices on the boat running indefinitely. Gear that would rely on the panels included refrigeration, lights, fans, laptops and navigation equipment, including a chart plotter. The goal was to provide enough power to minimize the need to use the engine to charge the battery bank while living aboard and on passage. To get started, we used the battery monitor to map the power usage of each electrical device and determined how much electricity each would consume in a day. For instance, the refrigeration compressor draws up to 4. We went through each piece of gear the owner had aboard, and we were able to estimate that 60 to 80 amp-hours would be used in a hour period when the boat was in use, and 15 to 20 amp-hours would be required when the boat was left unattended.

Simple Solar Power Circuit with Rechargeable Battery Backup

The two panels may be connected through the inverter in the battery back-up system. You will have an AC line coming from your main service panel which is connected to the “AC in” on the back-up system. The “AC out” is then sent to the sub-panel only, not back to the main panel. During a power outage, power will be supplied only to the backed up sub-panel, not to the main panel. This requires that you relocate specific circuits that you wish to have powered when the grid is down, to the new sub-panel.

This is best accomplished by a licensed electrician.

If you are looking to add a solar heating system to your swimming pool and have questions about how to install solar panels, read on. From simple, single on ground panels for easy set pools to multi-panel roof mounted systems for in ground pools, I’ll explain the differences and how to get them up and heating your pool in a weekend!

Do not use PVC as it softens at too low a temperature causing leaks. When cutting lengthwise, be sure to cut in a single channel for the whole length. Cut the ABS pipe into two lengths, each I picked this width so it would fit between the roof rafters in my attic. This will be easier if you pre-drill with a smaller bit and gradually increase the size.

The water flowing down the grooves, picks up heat from the metal areas between the grooves. At the bottom of the collector, the heated water is collected in a .

Click the button to see our most recent upgrades: I know that was quick and brief but hopefully it gives you an idea of what our set up looks like and how it works. As you see we have two 65 watt solar panels for a grand total of watts. This solar setup was pretty basic. We had it installed at the Monaco factory when we picked up Windy in February Basic, Medium and Heavy use. They had the most amazing, and efficient, RV Solar set ups we have ever seen.

These are nice guys we met on the road who are doing cool things with solar power, and we felt the RV community needs to meet them!

Use the sun to power small solar and battery powered night lights, garden lights, and decorations for halloween. The first part of a solar circuit is a device for collecting sunlight. To keep things simple, we’re using a single nicely made small solar panel for all of these circuits.

The numbers above show the savings with a solar PPA for an average home in Delaware. The typical electric bill before solar power is super expensive, but with a PPA, your monthly expenses will be lower. You’ll be saving money and saving the planet all at the same time! Here’s an estimate of the monthly savings for a solar PPA in Delaware: With a PPA, your solar company essentially becomes a second utility provider, only the solar electricity is sold to you at a lower rate than the fossil fuel electricity you’ve been buying from the electric company!

But it will save you money! The less-popular cousin of the third-party solar family is the solar lease. It’s basically like renting your panels for a set monthly payment, and getting all the energy they produce—however much it is. Don’t get spooked by that language, though.

The photo is then loaded into a program and spits out a whole bunch of calculations. Solar Path Finder So once you upload the image into the software and then trace the treeline outline, you enter in your location, date and time. My reading with the pathfinder Then it spit out all the calculations:

Installs in almost all wells beside the submersible. Pump from ‘ water level with only moderate effort. Pump to pressure tank. Costs less.

All the batteries we offer are deep cycle and designed for use in solar systems. You will need to decide how much power you need from your inverter, if you are only running a laptop and a couple of small things then you can use a small W inverter, or if you want to run large appliances you want to use larger 3Kw inverter.

The Outback and Victron 3Kw inverters can be stacked together to give greater outputs when necessary, including making a 3 phase supply. You want to use a Pure Sine Wave inverter to give a smooth power curve to your appliance to ensure it runs properly and is not damaged. Do not use Modified sine wave as they will cause damage to motors and sound equipment if run from them. We only sell pure sine wave inverters. The outback and victron inverters can be programmed to auto start a generator, or connect to the grid if necessary when the batteries are running low.

We would highly advise using the Outback and Victron inverters in preference to the cheaper models we offer where you can afford to, for example if you can cope with 1.

Solar powered fans are mounted on the top part of the plenum and these draw down warm, moist daytime air from near the top of the greenhouse through an improvised duct. and this arrangement turns out to be very simple to set up, since most 12V DC axial fans will happily run directly from solar panels designed to charge 12V batteries.

I used a 6 by 6 by 6 metal box for this. The junction box out at the array. The grey PVC conduit goes to the house. The black cord comes from the first in the line of micro-inverters. The junction box is supported on MDO plywood, which is very water resistant — its what freeway signs are made of. I did this wiring before connecting the micro-inverter cables to the PV panels, and before connecting the new circuit breaker to the house power, so there was no power applied to this circuit during the wiring from either the PV end or the house power end.

You will need one of these. The wiring connections in the junction box are: The grounding lug should be attached to the box with a self tapping screw so that it makes good electrical contact with the box. The wiring of the junction box at the array end. Make sure the wires enter through appropriate bushings. The Enphase interconnect cable comes in through a weather proof strain relief fitting.

The wire to house exits through the PVC conduit. The box comes with a metal cover to cover the open side.

The Radiant Heat Experiment (on a seriously low budget)

Considering the ever increasing price of fuel it really is a no brainer. Not to mention the reduction or even elimination of the wear and tear on the RV generator itself! A fairly common “irritation” out in the woods, for many RVers, is the RV “neighbor” who serenades us with the never ending drone of their RV generator. Cut your neighbors a break and install an solar power system on your home on wheels!

With a properly designed and installed RV solar power system you can greatly reduce or even eliminate the demand to run a generator.

One or two days of boondocking between sessions of hooking up to shore power does not require solar, and its auxiliary systems. You can get by for a couple of days on a reasonable size battery bank.

I don’t recall the peak voltage, but it went over The liquid in the battery made bubbling sounds and “boiled” freely the hood was open and no danger of a spark. I had a car battery last more than ten years that way. I also added EDTA early on and of course, made sure to add distilled water as needed. I suppose you were talking about a sealed or “gel-cell” battery though. Yes, the question posed was for a sealed lead acid battery, where any venting reduces capacity.

What you describe is more or less correct for a wet battery, and is certainly a good justification for the electrolyte active maintenance you did.

The Emergency Backup Power packages keep your home or business powered up when the grid is knocked out by blizzards, ice storms and other natural disasters.. Battery Backup Power can also be added to an existing grid-tied solar power system. Any of the systems below can work alongside your existing gridtied solar system.

Since the project is placed away from the house, it is more convenient to use a battery to supply power, rather than a long extension cord. During the day, the weather station should run from a solar panel as much as possible to avoid consuming the battery. And, rather than a person occasionally checking on the battery levels and replacing the batteries, the circuit should recharge the battery pack from excess solar energy from the solar panel.

This article describes the solar and battery backup circuit, along with the recharging results so far. Simple Solar Circuit Schematic of a simple solar-panel based circuit. A solar panel is on the left side of the schematic. A diode D1 protects the target device against a negative voltage in case the solar panel is installed in reverse. The diode is a Schottky type such as 1N so that very little voltage is lost going through it.

The device itself contains the usual power supply circuitry, such as capacitors to stabilize the power source and a voltage regulator to establish a voltage level usable by all of the chips and other components.

How do I wire solar panels to a charge controller?

There is now a choice of purchasing lightweight flexible polycrystalline solar panels. These could have been used to reduce the weight of our portable solar array, but we would have needed to build a frame, and these are not as solar efficient. Again we went for the higher priced, but more versatile and efficient unit.

SETTING UP A SOLAR PANEL/BATTERY AND 12 VOLT FRIDGE SYSTEM The formula is simple. Always choose a needs and set up accordingly. On average, the 80W solar panel [twin folding 40W] sitting flat on your roof in full sun will put out about out about 5 Peak Sun hour Equivalents.
