I have been looking into solar for two reasons: 1) quiet home emergency backup lights, medical and gas heat fan, and battery charging station. 2) Radio shack communication backup or standby with minimal led cfl type lighting. Centralized wall mounted led sconces @ 3500k brightness will illuminate more rooms and save energy.

@barndweller4573 7 лет назад

I have been running solar for a few years now out here in my barn. I started witht he few 12 volt panels then went with the 250 wall 36 volt panels. For the charging side if you run the panels (the same panels) in series and get the voltage up there is less need for the more expensive heaver wire. My batteries are about 50 feet from my man cave / shack and even with 2 runs of #6 wire on each side I needed to get on the the MFJ power boosters you spoke of. My Flex 6300 did not like the voltage dipping under 12 volts on transmit. My bank is 4 sets of 2 each 120 Amp Hour 6 volt golf cart batteries, I run the rigs (1 HF and 3 vhf) usually until 2 am every day and have never had a time when I run down to 12 volts at rest. I will never take mine under 12 volts the batteries are the most expensive part of my setup! Another nice video, THANKS

@mdouble100 7 лет назад

Excellent video, nicely done and comprehensive. I have 16 solar panels on my roof 8 460 Amp Hour deep cycle lead acid batteries in a bank connected via two charge controllers and an inverter. I power some of my house but not everything. All the points you've made are critically important for those considering using solar to power a HAM shack or anything else. My advice is to take care and buy tested and true quality components for the system. Spend the extra time to research every product carefully before putting it in your system. When it comes to solar systems quality really does matter. Clean power from a pure sine wave inverter is especially important. Be always aware of the negative impact of both heat can cold on your overall system. In summer heat can play havoc with roof mounted solar panels causing incoming voltages to drop. In winter cold panels will produce much more power and may create an overcharge situation unless the charge controllers are up to the job of controlling the power. The time and effort you put into designing and installing your system will pay back many times over, especially if you are dependent on solar. PS: A back up generator is a really good idea for winter months.

Wow how things have changed! New Lifepo4 batteries are lighter and last longer than lead acid battery and can give more power for size. Must have change controller! They can't take a joke! Over charge or over discharge can damage them, but this is true for all batteries. Just that the charge and discharge curve is different. They still give 12 volts when down to 15%, but start dropping fast after this. So you can get more out of them but need to be sure you don't take them to low. Keep in there large sweet zone they can last for 10 - 20 years some have 10 year warranty!

@DonDegidio 7 лет назад

Hi Dave, This August will be one year that I had Solar City install a 4Kw (15 panels) system on my roof. I just returned to the hobby and did not have a station up and running before the install was started. I had read articles about RFI from solar panels, but had no way to know if I was going to have that problem. Now that my station is operational, I do have periods of interference mostly on 20m. Need to get a portable receiver to go scout out where the interference may lie. 73 WB3BJU

@davecasler 7 лет назад

The issue with the panels, or more accurately, the associated switching power inverters and whatnot, is the harmonics from the square-wave switching transistors. This would probably manifest itself as buzzing at multiples of the switching frequency, usually about 50 kHz or so (at least in the past), and would tend to die down as the frequency went up. If you can correlate your interference with the activity of the panels, then ferrite chokes on the cables will help. Hope that helps! 73, Dave

@Jason-jd1jv 7 лет назад

I'd like to see a video about D-Star, System Fusion and other proprietary digital modes. Do you ever use any of them and if so, do you have radios specifically for them or was it an afterthought after purchasing a radio with one of these capabilities? I'm also curious if one is better than another or, more to the point, does one have more limitations than another? This may be a subject that is too broad in scope for a video and then again, it may be much simpler than I thought. I'm thinking of upgrading radios and I'm just wondering if any of this is something I might base a decision on or simply not worry about it.

@davecasler 7 лет назад

Jason, there are proprietary systems competing with each other. We have no digital voice repeaters here on Colorado's western slope, so I don't have much wisdom to offer. I suggest asking your local club members, as they may have a favorite that's most common in your area. Good luck! 73, Dave, KEØOG

@sammas7440 Год назад

I just installed two 100 watt panels (full sun in SoCal all day at a 34deg angle to the South), 40 amp MPPT charge controller, and 200ah LiFePo4 battery and a 3k sine wave inverter. I connected my IC706 to the Load Output of the charge controller (mfg said the output is rated for 40 amps). Is this ok, or should I connect the radio to the battery terms? What is the best practice to ground this setup. Currently, I have a 8' copper rod (a couple feet from my shack) into the ground, with a AWG2 to a good commercial quality buss bar in my shack. Along with my tuner and radio, do I ground the neg term of battery to the buss bar? Do I ground anything else in the to the common buss bar? Do I ground my Hustler 5-BTV to the ground rod?

Hi Dave, im confused about something. I have a 300w solar charge controller. My 150 w solar panel puts out 18 volts. My controller says it needs 20-50 volts input to work. Do I have the wrong controller?

@Jimwill01 7 лет назад

A question that is bit late - but I guess better late than never! I have a 12 volt 45 watt system that consists of 3 panels (15 watts each) that I have run through an MPPT charge controller. Recently I was given two 24 volt panels with higher wattage. Can I connect two of the 12 volt panels in series and parallel them with the 24 volt panels? I have read else where that the panels should be "matched" so that is why I'm wondering. Oh, and I have always ran all my ham gear (Icom IC718 and Alinco 2 meter)from solar, only problem was when the "deep cycle" battery developed an internal short.

@davecasler 7 лет назад

If the two 12v panels are the same size, then yes, connect them in series and then in parallel to your 24v batteries. I'm assuming the panels are relatively new, like in the past 10 years or so.

@matthewmiller6068 7 лет назад

For your batteries, do you fuse the batteries separately (in case one malfunctions - I had a cell go bad in my car battery and assume it could on a standalone system) or just fuse the bank of batteries from the main feed? Also, how do you tell the real MPPT controllers and real Pure Sine inverters from fakes? I have had a couple of the inverters that said "sine wave" but when I got hold of a scope it was a series of square steps.

@davecasler 7 лет назад

I fuse the battery bank. That's the way I've always seen it done. Because of the safety issue here, I'll caveat this that you should do what a solar-qualified electrician says. Regarding the MPPT trackers, I think there are no guarantees if buying on eBay or Amazon from abroad. I'd suggest sticking with vendors such as Samlex that already have an established reputation. That said, my inexpensive little charge controller for my 24v battery works beautifully! 73, Dave, KEØOG

@VanishingNomad 7 лет назад

I have a UPS for a computer. It throws out a surprisingly large amount of HF interference. It sounds like a pulsating "Buzz" sound. I don't know if this is the inverter, or the charge controller. When I start moving into solar, how do I know which Charge Controllers and Inverters are going to not cause this kind of interference on my station?

@davecasler 7 лет назад

This is an ongoing issue, as noted in a recent QST article. So far as I know, there's no "safe" list. As I mentioned, I did have to take one inverter out of service because it created RF noise. I wish the ARRL tested inverters and charge controllers! 73, Dave

@lyfandeth 5 лет назад

Here's a funny thing, Dave. You actually should not charge your batteries with DC. It forms microbubbles on the plates and slows down the charging while cooking the electrolyte. Instead, you can gain 10-15% more efficiency, and reduce boiling, by using pulse width modulated DC. (PWM controller.) Or, better yet, use an MPPT controller, which will give you 10-15% gains and beat what a plain PWM controller will do. Using raw panels, without an MPPT controller, is just using brute force, wasting power, and shortening battery life.

@davecasler 5 лет назад

The bubbling in lead-acid batteries comes if you charge with too high a sustained voltage. My charge controller is MPPT. Don't connect a solar panel directly to a battery without a charge controller of some sort in place.

@davecasler 5 лет назад

A 12v battery that has "rested," meaning hasn't been charged or discharged in several hours will put out 12.7 volts when full, and 12.0 volts when half empty. Unfortunately, that latter voltage is too low for many of today's HF rigs that are used to 13.8 vdc. MFJ and TGelectronics both make battery boosters to get the voltage up to 13.8. I have the TGelectronics one in my station, which runs off batteries.

Solar is only 14% efficient, and most radios just sip power, why not save all that trouble and just plug it in the wall. No panels, no inverters, no lead acid batteries laying around. No worries about snow covering the panels all the time and trying to shovel them too. We got enough to shovel around here in the winter to keep getting on the roof. Ive done the math and it's WAY cheeper and better, and easier to just plug the radio in and run it.

@davecasler 5 лет назад

I don't think expense has anything to do with it, though panels are now widely available for around $1/watt. I've explored solar for over 20 years now and find it a cool hobby in its own right. That said, my system is disconnected at the moment.
