    Weco vs. Pylontech?

    Hi, I have three options in regards to lithium batteries, Everexceed, Pylontech and possibly Weco. I´m not very fond of Everexceed that has 5000 cycles at 80% DOD and no BMS. So how are your experiences with Pylontech and Weco? I get 3 years of warranty on the Pylontech, but I understand...

    What are your experience with Growatt and their service?

    I thought most Growatt was high-frequency inverters? It´s difficult to buy from outside Uruguay, so whoever Ian is, it´s not an option.

    Adjustable tilt vs solid mount array for solar trailer build

    When you get above about 45 degrees relative to horizontal, you stop winning energy in the wintertime with increased angle, but are loosing heavily in the summertime. I´ve made some calculations, but they are particular to my location.

    I´m considering SPF-5000 TL BL-UP, because of the higher charge rating and switching time.

    Thanks, but I´m in Uruguay, so that´s not an option for me.

    Yes, I´ve heard about that, so that´s why I´m curious about it. I´m not sure I can get a low frequency inverter here in Uruguay, everything here is Chinese. This guy seems to be able to start a compressor, that already have some pressure in it 29 mins in:

    Do you think Growatt is a serious company? I´ve been trying to get some kind of surge rating from them, but they only asked where in the world I live and then they didn´t trouble themselves with answering.

    Designing a Stand-By System?

    If economy isn´t much of an issue and you´re willing to change the batteries once in a while it might be fine, but else I would be concerned about letting the batteries stand and do nothing in a stand-by situation, I think most batteries go bad if not being used for a couple of years. If you on...

    Mechanized pole mount

    You are most likely not going to benefit the environment by a lot by doing this. You have to consider the dirty power used to mine the materials, make the panels, transport them e.t.c. Also the materials that goes into the frame and tracker. Then we have the inverter, same issue, with the added...

    Adjustable tilt vs solid mount array for solar trailer build

    Yes, even if you found the optimal angle according to your preference, you might change your preference later and then it´s no fun to invest in a new support for the panels. The drawback to your particular situation could be driving on a bumpy road with a flexible mount, it would have to be...

    The real off-grid situation :) If you depend on spareparts, you´re indirectly on-grid.

    Adjustable tilt vs solid mount array for solar trailer build

    Another thing I considered is that we rarely get golf ball sized hail where I live, so wouldn't like to lay them down flat. Anyway I want to optimize for winter sun, so where I live 49 degrees relative to horizontal is optimal and if I don't get to cover the panels before the hail, they'll sort...

    Love it! 😁 I moved from Denmark to Uruguay, 1 km outside a small sleepy town. I noticed exactly the same as you. Denmark had become a fascist police state, they are really chasing people for nothing. While at the same time they let the big criminals run. Where I live now I know the police...

    Lol :-D But you´re right, today it´s getting increasingly difficult to have money with inflation, negative/zero interest and Central Bank Digital Currencies (CBDC) coming. A piece of land stays under the feet :)

    Why in the world would you like to have 40 acres? Sounds like a lot of maintenance? I have 2 ha (about 5 acres) and that´s more than plenty for anybody who´s not a farmer :) I´m new to solar, but have been investigating a lot and I think it doesn´t sound unreasonable in regards to economy...
