    Keeping it simple stu...

    Retiring before death is a goal of mine and should I achieve said goal I will then build a battery that does my offgriddle paradise justice. For now, I have to keep it simple, quick and cheap and I'm overdue to replace my first pair of lifepos with something more beefy, yet still temporary. I...

    Cool & sunny is better.

    Cool sunny days are better than hot sunny days for solar gain; don't forget to calculate for PV panel thermal loss where applicable. Peace. :cool:

    Chat Rooms are not anything new under the sun ..

    Chat rooms are certainly nothing new under the sun, but wouldn't it be cool to have one here, only open when there is a live moderator in the room of course? Anyways, these photos are of my latest solar project in the works. Regards, OG

    How Forgiving are built in BMS's?

    When mixing different brands of 12 volt, Lithium iRon Phosphate batteries containing built in, non used programmable BMS's, is there a compatibility issue amongst the different BMS's when the batteries are connected together?

    You would think that I could use the cam switch as a simple two pole manual transfer switch but NOOOOOO!

    Ok, I purchased this three phase BAOMAIN, SW26-63/D303.3 cam switch switch in hopes that I could use it as a simple two pole transfer switch to supply 110VAC to a tiny off grid home by switching between generator power OR inverter power. I tried "ohming it out" with my volt ohm meter so I could...

    Bluetti Update WITH handy series parallel diagram, (see foto)!

    At present moment, these four, 160, watt panels are hooked up in series pairs then parallel to produce approximately 42 volts which is fed into 150' of #8 gauge copper wire to charge a new, 2400 watt Bluetti. With about five hours of direct full sun per day, it takes about one and a third...

    I'm still performing testing and recording measurements on my "measurement question" post and thank you everyone for your help. On a side note, this lithium powered bike came in this week. Because of the WWCFP, (World Wide Covid Flu Panic), the homesteady who purchased it had to order and wait...

    Measurement question ...

    A wattmeter reads how many watts are flowing through the meter on the way to a load, therefore, a wattmeter cannot necessarily give an accurate, maximum, reading of how many watts a panel array is producing, UNLESS, the load is asking for 100% or more of what the panel array is capable of...

    Panelos

    The homestead was all abuzz upon the arrival of one out of six 160 watt panels purchased directly from Rich solar. Breaking the one dollar per watt threshold, the panels cost $140 each including the "free" shipping. FURTHER ADDING TO THE EXCITEMENT, the homestead executive purchasing officer...

    Six and a half years with no refrigerator ... the saga part three.

    Hi all, THIS 2400 watt Bluetti arrived Friday ... the 1500 went back to the vendor and while she did not apologize for sending a 1500 when we purchased the 2400, she did eventually refund the money because she had no 2400 to send. Amazon also deserves honorable mention for their...

    Well, technically I have had refrigeration courtesy of mother nature for approximately 6 months of every year, but now there's a new DC freezer in town, almost. Frankly the new Whynter freezer belongs to my homestead neighbor who said I could freeze water jugs and rotate them out every few...

    Solar gain in the snain.

    It's both snowing and raining at the moment so at least some progress is being made towards that glorious week of summer. The solar panels are registering a lazy 14.3 volts at the input to the SCC which made me wonder: *ACCORDING to my Epever manual, when the green charge light is steady, that...

    why my solar system cuts out out intermittently on sunny days

    Like so very few USAmerican people I do not consider spectating a sport, in fact I do not consider spectating an activity at all. So instead of forking over a queen's ransom to buy expensive sports pay tv programming or hideously expensive tickets to sedate myself while I ,"go large", watching...
