    Modified Solar Wood Kiln

    I made some more progress on my kiln build. I finally decided on a dehumidifier to use and purchased. It should be here in a few days. I went with the AlorAir Sentinel HD55 - https://amzn.to/31wxNXH This should be more than enough to extract moisture and still is within my power usage envelope...

    45 foot shipping container rooftop solar.

    I agree. A 40ft container itself is around 4.5 tons. It will be ok. I am looking at doing similar with a 20ft container. It has a tare weight of around 2-2.5 tons.

    Modified Solar Wood Kiln

    I have researched the VT solar kiln extensively. My friend has a VT kiln and a sawmill. We have been using the kiln for the last 1.5 years almost continuously. I was going to build one for myself as his kiln is set up in the city. I am about 90 mins away in the country. Surprisingly he gets a...

    Modified Solar Wood Kiln

    I agree inside is too hot for batteries and monitoring controls. They will both be housed in a compartment I will hang on the end of the container. What fans are you looking at? I decided to go with some 8" HVAC duct fans. They are only 44W/.77A @120V. I got 5 of them. 2-3 to use for...

    Modified Solar Wood Kiln

    I am making progress on the solar kiln. I decided to go with a growatt hybrid controller. I purchased their 3000w 24v model several weeks ago. I have been testing the automation pieces and have had good success. I am able to measure temperature and humidity on multiple sensors. I am able to turn...

    Wire disconnect tool too big?

    That looks exactly like what I have. The prongs on the side and on the end are the same size though. Neither one fits these extensions. Is there a way to tell exactly what connectors I have? They dont seem to have any markings. But as I said above they do fit the ecoworthy 4 port combiner box I...

    Wire disconnect tool too big?

    I ordered what I thought was the right disconnect tool for some extension cables I bought locally. The tool is just one of the cheap blue plastic disconnect tools. It is too wide to fit in the slots. Is the tool wrong or do I have some weird extension cables? The cables fit on the 4 port...

    Newbie to solar water heating need advice.

    I am looking to do something similar with a wood kiln. I will have a solar hot water loop. I am planning on using software called Home Assistant. It is used for home automation. You can do just about anything with it and an add-on called node-red. Check it out it is free. You can even run it on...

    Modified Solar Wood Kiln

    Due to temp issues I am looking at AGM batteries like these. I dont want to have to worry about it as I have such a large temp envelope to cover. These batteries look like they will fit the bill. I would probably start out with 2-4. Comments? Has anyone used these particular batteries or can...

    Modified Solar Wood Kiln

    I am going to attach the solar panels and water heater loop to the top of the shipping container. You cant really mess with the integrity of the container to much by cutting big holes in the roof or sides without adding more rigidity. I am going to make minimal perforations for wiring, air...

    Modified Solar Wood Kiln

    One thing I am having trouble wrapping my head around is an enclosure for the controls. I am in NE TX. We can see anywhere from 10Fdeg to 115Fdeg. What am I going to have to do to not kill my batteries. I am leaning towards putting together a 24V system as above using LiFePO4 that are not as...

    Modified Solar Wood Kiln

    Then today I put a deposit on a 20' shipping container. Just a regular old beat up WWT. I do not want to afford the fancy side door container in the above picture just yet.

    Modified Solar Wood Kiln

    Yes I had planned on painting the South side. I dunno yet though. If I insulate the inside I am not sure how much painting it will help.

    Modified Solar Wood Kiln

    I am bouncing back and forth between a high end residential grade crawlspace dehumidifier(600$+) and just a regular in home room dehumidifier(200$).

    Modified Solar Wood Kiln

    Here is the plan in a nutshell: Want a solar kiln to dry wood. Thinking I can use a 20' shipping container to make a modified solar/dehumidification kiln. Using PV to power a 600W AC dehumidifier for 4-6 hours per day. Using PV to run a dc pump on a closed loop solar hot water heater to heat...
