For people wanting a smaller portable system, look to Bluetti or Anker for their all in one LFP "solar generators". For people wanting to put stuff together themselves, Here's a video of Will Prowse making one on a hand truck. I use this exact same inverter on my golf cart to run the pancake air compressor and sheet metal nibblers around the property. https://www.youtube.com/watch?v=PjdB5m38MTs

If you guys are running a portable generator, keep in mind that it'll run wide open at 3600rpm the entire time it's running. Read the manual and you'll likely find that you should change the oil at 25 hours or 100 hours. So you should be changing the oil at least every 4 days. What oil to use? If the generator has a splash oil system, look for the words "non detergent" or "ND" on the bottle. Ordinary automotive oil will foam up in a splash system.

Never shut down a generator under a load! If it has a voltage regulator, it will spike current to the armature as it's spooling down and burn up the brushes.

Savannah's first deer hunt. She shook hard for about 5 minutes after...not cold....it was her adrenaline dump. She was 9 years old and has begged to go with dad since she was 5. Since this time she has hunted Nebraska with dad and has11 deer harvests of her own. Thanks for viewing.

I want to thank all the wonderful positive comments on my video. Savannah and I have had a great time reading them. This video has been used in several hunting expo's, conferences and events all over the world as a positive hunting experience between father and daughter. It has gone viral far far beyond Youtube. Check out the link at the end of the video for her younger sister Sydney's first deer. Thanks and Happy Hunting........ Jason

I realize that most of us will not be doing land navigation but I just found an old compass in a cabinet. Decided to check the azimuth against a cell phone tower from here and it was off by 10degrees of true north. The booklet that came with the compass is probably 30 years old and shows 2°W for my area... but it is presently 8W. So I just calibrated the dial to true north. Just a fun thing to do. There's a small screw on the ring that allows the center scale to rotate.

Handy dandy morse code visualization.

I made a small programming change to one of my 48v DC solar chargers today that required it to reboot. That's the notch out of the dark blue at 10am. However, look at noon.... the dark blue represents total solar production and it dropped at noon and nearly simultaneously the light blue jumped up. What happened at this moment was the amount of power I exported to the grid increased when my house system's batteries got full and suddenly switched to selling power. If I permitted that 48vdc charge controller to continue making power it would export too much power and disconnect the grid. In that case I wouldn't sell much power for the rest of the day. So better to forego 3kw of power and still be able to export 17kw for the rest of the day.

For those wondering, the small amount of power exported to the gird prior to noon is a completely separate solar inverter that only sells to the grid and does not interact with the house.

Rose has been a bad girl on the chat and I’ve just unbanned many of you that I wasn’t aware were banned.

TLDR: if your solar charger/inverter won't connect to your generator, it might be that the generator is running out of spec on RPM or "line frequency".

Generators... 2 pole generators should be set to idle between 61-62hz (3660-3720rpm) in north america or 51-52hz (3060-3120rpm) in 50hz countries. One reason for this is that the generator will bog down a little under heavy load and this allows a little overhead before it gets to 59 or 49hz. Another reason is that if you run it in parallel with solar equipment, as the load comes off RPM will rise.... as the frequency gets over 60.5 or 50.5hz, the solar equipment will not connect and thus not back feed your generator and blow it up.

From here out, I'm going to not say 50/60hz... just know that the theory applies to 50hz markets.

An example of how varying frequency is used on the solar side of the house... older solar inverters will only connect if the frequency is 59.5-60.5hz. Newer inverters will stay connected from 59.5 thru to 64hz. A neat thing happens with the newer ones.... if the line frequency is 62hz, your solar inverters will remain on "hot standby" but making 0 power. if you turn on something like an oven in the house, the generator will dip to a lower RPM. As soon as the line frequency goes below 62hz, the solar equipment will start making more power.... all the way to 100% of what it can make at 61hz. Between 59.5 -61hz the newer solar inverters will make 100% of what they can. Between 61-62hz they will ramp down to zero. This allows you to run your generator in parallel with solar equipment without the solar equipment damaging the generator.
