The Thunderbolt Magnum 100w Solar Panel Kit is on sale, with coupon, from Harbor Freight for $149.99 through October. Re: Newb - Harbor Freight Kit + Eagle II Wind Generator - Few Questions Um, actually no. The box and ads suggest that you can simply plug into cigarette lighter. Question: has anyone done this yet.? Just bought a Thunderbolt 1.5 watt solar charger for my RV from Harbor Freight. One diode with a sufficient rating is somewhat preferable to two under-rated diodes in parallel (because the two may not divide the current evenly). Should it be putting out more volts with 145watts? Protect your 12 volt lead-acid or gel cell battery from overcharging and deep discharging with this 30 amp solar charge controller. They were on sale and I purchased two more kits. Mine is off 250mV or .25V This is a big deal when using batteries. We cut out the middleman and pass the savings to you! Amperage would have to be determined by operating conditions. Attached is what I'm thinking. Finally, make sure to add an inline fuse near the battery terminal (such as 5A). Solar Panel Charger; Slide Log Splitter; 100 Watt Solar Panel Kit; 100 Watt Solar Panel; 5 Watt Solar Panel; Save even more with the harbor freight credit card. : Like many of us who are interested in solar power, I bought a Harbor Freight 45 Watt Solar Panel kit for about $150 which came with three solar panels, and a charge controller. In fact, the voltage would go down about 0.1 volt to become 12.4 volt. Participated in the Instructables Outdoor Projects Contest. Our homes are beautifully decorated, pet-friendly, and located in safe, family-friendly, and vibrant neighborhoods throughout the Northeast Ohio area. During the day, the front panel shows about 13-14 volts so I leave the charge controller on, but when I come back from work, I found that the battery wasn't charged at all. Compare to. I do want to make sure it's safe and that my approach makes sense. Then there is always wind generators. harbor freight solar charge controller schematic. Thunderbolt. It’s a 555 based simple circui… Bill of Materials. "F1" would normally indicate a "fuse". The solar charge regulator features three LED indicators (high voltage, low voltage, charging) and three connections for the solar panel (keyed two-pin connector), battery (keyed two-pin connector) and 12v output (3 in. Since I don't know the charging circuit inside the box, the effect of this added blocking diode on the solar panel and battery charging is not clear. Page 14: Parts List And Diagram List and Diagram part Description part Description Solar Panel Screw 4-in-1 Splitter Cable Connection Brace Charge Controller DC Connector & J-plug Battery Clamp Cable Wing Nut LED Light Page 14 For technical questions, please call 1-888-866-5797. pigtail). What is the part number for this component? Given all the unknowns, I wouldn't risk charging any expensive batteries. Solar Charge Controller; 5 Watt Foldable Solar Charger; 500 Lumen Light; Related Categories. I also obtained the schematic I am working to changing the charge voltage from 12.5 to 14.0 DC max. Seeking more power than what a 1.5 watt solar panel could provide, it’s time to step up to the 100 watt solar kit, Harbor Freight item #63585.The manual, posted online as a PDF, fails to describe a few useful details which we’ll cover here.. Reply It’s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source. 1N5822 can handle 40v 3A so I use two of them in parallel to make sure it can handle the current from the solar panel. 44118-2160, The Cleveland Real Estate Investor Podcast, Cleveland Ohio Real Estate Investment Opportunity – Turnkey Solution Targets 6-10% ROI, Cleveland Rocks (But You Already Knew That). Harbor Freight buys their top quality tools from the same factories that supply our competitors. 1) Do not put blocking diodes on the battery - the whole point is that this system stores energy into the battery as well as taking it out again, so that flow needs to be two way. For now, I need to move on to the next project with desulfator. Batteries now days can handle up to 14.0 volts DC. download BOM xls file . So what is the blocking diode for? Harbor Freight #63585 100 Watt Solar Kit Seeking more power than what a 1.5 watt solar panel could provide, it’s time to step up to the 100 watt solar kit, Harbor Freight item #63585 . A low 1-amp rate is also good for warming the battery of a vehicle prior to starting it on a cold morning. To maintain efficiency of the Solar Panels, it is recommended to disconnect them from the Charge Controller at night. Sunforce 60022 at $99.99. Sunforce 60022 at $99.99. I suspect that when the voltage from the solar panel is below the voltage of the battery, it may be discharging the battery. This unit is compatible with Tracer A(N) , TRIRON N, Tracer BN, VSxxxxBN series controllers ONLY from EPsolar. Op states to place the stripe towards the charge controller. mines fried too. pigtail). There are advantages to having a solar battery backup in certain situations, but it’s not essential for everyone.. I had it hooked up wrong. NEW. Both charge controllers failed after working fine the first day and the next mornig both were down around 2.5 V output. 5 years ago, Amazon has a 100w pannel for about 15dollars more much much better i purchased one and it works very good your choice why I got a 45 watt system when you can get a hundred lot system for ten fifteen or twenty dollars more, Do not buy from harbor freight.i did bad choice, Can I add more panels to this charger controller or does the controller only accept x amount of input and if so what is the x amount, the charge controller can only handle 100 watts. Compare to. Just bought a Thunderbolt 1.5 watt solar charger for my RV from Harbor Freight. Reply I will be getting two batteries for it. Rover Elite 40A MPPT Solar Charge Controller . Thunderbolt. PV and turbine both connect directly to batteries. The longest tape measure I have is 25' but based on the length left over, it looks like the overall stretched-out length is 30'. You actually need a single diode that can carry the entire load. Use a multimeter to measure the entire system, from the solar battery and solar charge controller to the solar panel, first disconnect the solar panel and measure the voltage, as long as there is sunlight, there will be solar output. David Parker says: December 7, 2020 at 2:11 pm . I would suggest that, if you setup the system correctly and find it does discharge (the battery) when the Sun goes down, the unit is defective. Solar Charge Controller – Keeps the solar panel from over charging your battery or batteries. The instructions, however, say that you should not use it without a voltage regulator. I bought a Harbor Freight 45 Watt Solar Panel kit for about $150 which came with three solar panels, and a charge controller. A low charge rate of 2 or 1 amps is ideal for charging motorcycle and lawn mower batteries. Add to Cart Add to My List. If you do use a diode, make sure it has enough current rating (and that it's placed so it's OK to get hot). Test your charge controllers people. pigtail). Email our technical support at: productsupport@harborfreight.com. The Thunderbolt Magnum 100w Solar Panel Kit is on sale, with coupon, from Harbor Freight for $149.99 through October. The diode I am using is 1N5822 which happens to be in my toolbox so I guess many other diodes would work as well. The Bonneville sun should turbocharge it! This is very much an experiment so be careful not to overcharge. I initially placed the diode on the battery side but based on recommendations from "evilmunkey", the diode should now be put on the solar panel side. 30 Amp Solar Charge Controller. Sunforce 60022 at $99.99. The housing is a very nice aluminum extrusion which is also used as a heat sink for the electronics. Amazing deals on this 100 Watt Solar Panel Kit at Harbor Freight.
