[@JamesKC3OXN]

Thanks Julian, for the insights. I wish you were putting out more content because I'm addicted to this stuff right now. I'm in the process of developing a network of hams for what I'm calling EM4P "EmComm for Preparedness". It's very difficult to get information that isn't the EmComm associated with public service i.e., ARES/RACES, etc. The ARRL seems to have captured the emcomm market and hasn't left much for those of us that are concerned with personal preparedness and dealing with SHTF situations. I'm not against someone volunteering for public service, of course, but I want to form networks that are separate from any public or commercial enterprises, as I'm certain if things got bad enough, we couldn't expect to rely on anyone but our people. Perhaps you could make a video that touches on this subject a bit deeper than you have already. I trust your thinking on these matters. 73 KC3OXN

@@OH8STN I have always understood this to be the case as well. Interestingly, however, I was surprised to see the manual for the Genasun GV-10 (purchased June 2022) recommends connecting the CC to the panel first. The manual states, “While connecting the battery first will not damage the GV-10, we recommend connecting the panel first. This eliminates the risk of short-circuiting the panel while the GV-10 is operating, which can cause damage.”

Excellent presentation! I love your setups! I want em all! I have too many projects going on! Building my rig, a 99 Jeep Cherokee XJ, I'm also setting up a solar rig for running my Ham Shack and emergency backup for my oxygen machine and CPAP machine! I'm getting ready to order my first batch of batteries! I've decided to start with a larger 280ah 12V cells in battery boxes. Going to build 2 and start at 24V. I bought a 2500w inverter, 24/13.8V 20A step down transformer. This way seems best for my needs. Serves me immediately. I can pull one for trolling motor use or camping. I am going to build a 3.2V 100AH X 16@ 51.2V and design my own case with the intention of a rack of 6 for the house system and a larger 48V all in one inverter. I am also planning on building 2 of each of your smaller battery packs for portable ops. Julian, I love your channel but Dad gone it, it's expensive trying to keep up with you !!!😂 Semper Fi!

@@OH8STN Hey Julian, I don't really stick do a budget here. I already have a KiwiSDR, added Wifi and also have 2x 6Ah 12V batteries. My main concern right now is to find a solar controller with low RF noise emission. I also run one of the Victrons on my boat which is great with gathering statistic data and has a great overall performance but is maybe overkill for charging 12Ah batteries and could need some tweaking RFI wise :) I will keep you posted if you like. Also if you want any technical details. Too much information for a youtube comment ;) 73s, Andy, DG7LAN

Bought a charge controller and ht from gigaparts, they came in yesterday.

[@dougdaniels]

Thanks for another great segment in this series. I was wondering if you could do a review of solar panels with respect to quality/efficiency, cost and weight values for these projects. For instance, the Powerfilm 60w foldable (3.2#) is $900 while the 40w Bioenno (3.97#) is only $125. It's 50% more power at about 25% less weight, but 7x the cost. I never want to trade value for price, but some of us need to get the best system we can afford. 👍

[@OH8STN]

It's a good question and the great point. It's quite much work to feature the budget panels on the channel. As the risk is so low, I wonder if a community approach would be better. If the community buys them, tests them, then shares their results, I would be willing to share those results on the blog or Channel. This Channel won't have to purchase all of these panels, pay the shipping, the import tax... for something I'd probably never use again. It's brilliant idea but something I'd prefer to do as a community, rather than the channel using all of its resources and taking all the risk alone. Does this make sense?

[@dougdaniels]

@@OH8STN Absolutely makes sense. I wasn't sure, with your network of technical Hams, if you'd be able to source the different gear among them for analysis. On a similar note, I'm looking to get a Buddipole Powermini2 as soon as they are available again. I am currently using the Bionenno solar charge controller, and would be happy to share my comparisons. TU et 73.

[@OH8STN]

@@dougdaniels sticking to solar panels as your first mentioned. All of the budget panels are rebranded panels from china. It doesn't matter if it's Bioenno, Goal Zero, Jackery, Bluetti, Ecoflow, ... They are all usually made in China. The best advice I can give regarding the budget panels, is pick a brand, read the reviews, then find the best deal. Just avoid the completely unbranded Fly by Night panels. I particularly like Renogy as an option, and will show them on the channel during the autumn. If you'd like to understand how to compare other panels to powerfilm, here's a post I wrote explaining Powerfilm panels specifications, manufacturing and certifications. Once you read that you will understand why the military uses them. oh8stn.org/blog/2021/06/24/powerfilm-solar-foldable-vs-rollable-solar-panels-and-others/ If you don't need a backpack portable solar panel, please check out Renogy.

[@cojim]

Just a suggestion to simplify all the different connections between components in a portable power pack: use different color PowerPole connectors based on function. For instance, I use yellow/black PowerPoles for solar panel to charge controller wiring, lavender/black Powerpoles on the charge controller to battery wiring; and orange/black Powerpoles on the battery to the power distribution bus. All connections from the distribution bus to the radio and other 12 VDC accessories use the typical red/black Powerpoles. Note that my portable operations are typically not "camping" portable but mostly RV portable at remote sites without the typical utility connections. Mine consists of a 20 Ah LifePO4 battery with an MPPT charge controller, plus various PowerPole, USB, and a 12 VDC accessory socket. I also have a battery status meter that shows state of charge (percentage), amps remaining, and battery voltage. My rigs include an Icom IC-703 for QRP operation and an Icom IC-7200 for QRO operation--the latter is the primary reason for the larger capacity battery.

[@Subgunman]

Color coding connectors is a great idea, I have been using white/black for my solar panel to controller connection. Red/black stacked top bottom for battery to controller and standard config for power to equipment hook up.

[@tunnelrabbit2625]

Wish I could afford all that great equipment, but there are competing priorities, so one can only do what they can on a tight budget. There could be interest in getting it done on the 'cheap' .

I don't necessary need it to be pocket size but, I want to be able to pack up and if I have to go, I would like to have my radio gear ready in case. I want to be prepared for off grid radio.

Great videos, Julian. You briefly mentioned using an efficient PA for QRO operations. Do you have any experience with the Hardrock-50 amp? I'm curious how it would fit into your operating paradigm.

[@OH8STN]

The Hard Rock 50 is an amazing amplifier. The only reason I didn't choose that one, was its weight. It's more of an amplifier meant for the desktop when using a qrp radio at home. The PA 500 in contrast, is an amplifier meant for the field. So I absolutely love the Hard Rock 50 as a home amplifier. Hope this helps. 73 Julian oh8stn

[@OH8STN]

Well it's easy to measure the VHF UHF gear. You just need an inline voltage wattage current meter. Your laptop might be a little bit more complicated. If you have a 19 volt laptop how do you get power to it when you're out in the field? I always recommend field radio operators use laptops with USB C power delivery Thunderbolt 3 charging. Then we can simply use a cigarette lighter adapter for USB C power delivery from our battery pack, to the USB C port on the laptop. If you have a 19 volt laptop and you're using an inverter or something like that, you'll have to measure it between the battery and inverter to see how much the laptop and it's power system are using.

OH8STN, why did you choose MPPT over an PWM?

Pwm charge controllers are noisy. They put RF hash all over HF Spectrum making it difficult to accomplish weak signal work. Moreover mppt is constantly searching for the maximum power point of your solar panel configuration, making the best use of the energy coming in.

[@OH8STN]

You'll have to be a little bit more specific. When you say small portable power station, what capacity and to power what? I generally have multiple power stations. Some of them are pocket size, others are larger. Each of them has a unique purpose like powering a radio or Keeping the refrigerator going in a grid down. The one thing I've learned on this topic is there is no such thing as a 1 size fits all. If we get it wrong,l we can end up leaving them behind Because they're too large.
