Great, thanks! I have all the gear ,(vacuum pumps, gauges for many refrigerants, nitrogen purge system, etc) BUT I only have an EPA 609 license, and thus can't buy or work with R-410A. So unless the precharge compressor and inside coil include a bit of extra refrigerant for filling the lineset...

So is it just the line sets that may or may not be pre-charged?

High temperatures here have been running around 101˚f/38˚c. The solar power equipment is in a small concrete block shed. A few years ago I put in a 14k BTU "Through the wall" AC unit, powered by the inverters @ 240vac. (The previous owner had already made the wall opening and installed a...

Mine is mounted on the West wall of a concrete block shed. Setting Sun heats up the wall. I put a shade outside to keep the wall cooler. Insulated the doors, which the thermal camera identified as a heat source. Put a large box fan blowing on the system from across the room The best thing was...

Thanks JustJoe! I have a 3 year old Conext gateway (865-0329) It is running v1.17, XW-Pro's are running 1.11.01bn49. I powered off the gateway, removed the original micro-SD, put in a generic 32G micro-SD, (Lexar 32GB ), powered up the gateway. After a few minutes, logged in and was...

WOW, thanks, that is a really nice solution, I'll learn more about it!

Yes. When the heat pump is running. I plan to open the breaker w/ the heat pump turned off, then start the heat pump afterwards . For some reason, this procedure does not effect the heat pump.

Investigating methods to open a breaker remotely. All the solar electronics are installed in a shed, 200 ft. behind the house. There is 60A 2P Square D QO breaker in the shed that provides grid power to the Schneider XW Pro inverters for "Grid Support". I need to open this breaker from the...

I like DIY projects! Dad passed when I was 2, mom never re-married, so I grew up alone. (mom was always working) She had kept his tools from WW2 Navy work. No way to pay anyone, so I learned how to fix things around the house at a young age. Carpentry, plumbing, painting, electrical, masonry...

I always use QO, probably because all the industrial work I did years ago was QO. Local Home Depot has most sizes in stock, but I also look @ ebay for used QO breakers. I buy whatever lot is available and sort them out, cost is a fraction of new, and they still work great.

I have used these to protect POE Ethernet, in cases where running fiber was not practical: https://www.polyphaser.com/gigabit-ethernet,-poe-surge-protector-lightning-arrestor-series

Yep, Winnebago, built on a Mercedes Sprinter 3500 Diesel truck chassis. Just enough for two of us, 13-14 MPG towing a little Honda.

We just returned from a week @ the beach, first time w/ Starlink, great! I put the WIFI and PS in the side compartment of the RV that has a power receptacle and a small opening in the floor to run the Ethernet cable through. Put the antenna on top of the RV. App showed me the best alignment...

Cleaned the filters on the XW Pro's for the first time today. Inverters have been in service for about 3 years, installed in a shed. Did not look plugged up, just dirty. High temperature here will be 96°f in a few days, so cleaning should provide all the air flow possible. I used compressed...

Hamfests, local electronic surplus stores, eBay…..
