    What Budget 200Ah LiFewPO4 to buy for freezing weather August 2022?

    Thanks for the heads up on the Lisuateli brand. So I read the Q&A and guy opened his and found they are pouch cells. I have no info about the reliability of pouch cells, anyone want to chime in? Other than being pouch cells all the reviews seem positive.

    What Budget 200Ah LiFewPO4 to buy for freezing weather August 2022?

    Just leaving them connected in the camper with the solar disconnected, but AC Power connected, and the battery dips below full charge then tries to take a charge in the winter when it is cold. I tend to use my camper as a Man Cave to escape honey do's over the winter.

    What Budget 200Ah LiFewPO4 to buy for freezing weather August 2022?

    I am having a hard time finding a budget 12V 200Ah LiFePO4 battery with low temp shutoff, that can stay in my camp trailer which sees 10F to 140F temperature swings over the year. I had purchased an "Energized Outdoors" brand battery that listed it had both low and high temperature battery...

    Quick check, Epever 10A SCC Series pair 200w 24v panels?

    I ended up going with the 20A SCC, and returned the 10A. I was able to make the 20A just barely fit the spot I had, by laser cutting a mounting plate with top and bottom screw holes instead of using the SCC's side mounting flange screw holes.

    Quick check, Epever 10A SCC Series pair 200w 24v panels?

    I actually ordered the RS485 to USB cable. I have a 12v mini pc for a media player, a 32" 12v monitor, and a 12v soundbar in my camper. Should be easy to setup with the windows software. I am trying to do everything I need with 12V in my camper. Edit: I'll look up and order the temp sensor too.

    Quick check, Epever 10A SCC Series pair 200w 24v panels?

    I went with the 20A SCC, because of size. I can barely fit it where it's convenient for wiring, however the 30A model is 1/2" too wide. The 20A is supposed to be able to output 260W for 12V, and the unit is supposed to be rated safe for solar inputs 1.5 times the 260W output, or 390W. Since I...

    Quick check, Epever 10A SCC Series pair 200w 24v panels?

    Thanks for your reply. I edited to clarify my post. I assume then that the specification of naming an SCC as a 10A solar charge controller means then it will only OUTPUT 10A to the battery. I was under the assumption that the naming of a 10A solar charge controller meant it can only take in 10...

    Quick check, Epever 10A SCC Series pair 200w 24v panels?

    I have a pair of Rich Solar 24v 200W panels on my camper, feeding my Bluetti AC200, working fine, and by noon the Bluetti is always fully charged. I want to charge 600Wh (12V 55Ah) worth of LFP boat battery with these panels each day too, so I plan on connecting the solar panels through an...

    Series Parallel 100W with 190W panels...Are Specs Close Enough?

    Thanks for the reply, I thought I had done enough research and properly mix and matched a system as best I could for my RV, but I just had to hear from someone on this forum that I came up with a workable combination. I just didn't want to find out some surprise that I overlooked. I had been...

    Leaking Electrolyte from Bigbattery Powerblock

    I just read this topic, and wanted to throw something out there about HF. I worked in the semiconductor industry for 40 years, and have extensive experience with both Hydroflouric Acid, and Hydrogen Flouride gas. It is used to eat away glass or Silicon. I have been burned by it, and I have seen...

    Series Parallel 100W with 190W panels...Are Specs Close Enough?

    I watched Will's Bluetti AC200 video last spring, and got mine from the Indiegogo campaign. I wired it into my 7'x14' toy hauler to run everything except the rooftop AC. I want to use Solar panels to charge it, however because of the placement of the rooftop AC and the roof fan, I cannot fit...

    Super Cheap Shunt Wiring Question

    Thanks so much for your reply. I thought the wiring seemed redundant at first then it occured to me that this meter says nothing about being bi-directional, so by swapping the Yellow and Blue wires, the meter can measure total Watt Hours going into the battery, OR going out of the meter, and...

    Super Cheap Shunt Wiring Question

    I want to measure (don't need to be super accurate, within 5-10% is good) the Watt Hours that I can get out of my 55Ah LiFePO4 in my trailer, but am too frugal to pay for an obscenely overpriced shunt/meter. I ordered an under $20 set, and this is the wiring diagram: So my question has to do...

    My first solar project plan... Please evaluate..

    OK, Now I see what is not workable. I did not realize that I need to see an actual AC grid tie to turn on. I thought the output of the 4 panel microinverter could feed an inverter-charger directly, and at sunrise, somehow internally see the AC output of the inverter-charger as a grid tie to...

    My first solar project plan... Please evaluate..

    OK, Thanks for the reply and calculator spreadsheet. The spreadsheet is very helpful. About the microinverters, the thinking was to simplify wiring by using microinverters to convert the solar panels output into AC right at the panels, and I would be able to use 14awg wire to the inverter...

    My first solar project plan... Please evaluate..

    I came up with: 1670 Watts Full Load 3750 Watts Full Surge 2560 Watt Hours Full Load Also of note, I usually only get full sun when it is directly overhead in the summer as I would be camping in the pines mostly, and in the fall I camp in the open, but may have overcast days.

    My first solar project plan... Please evaluate..

    My name is Robert, and I have a camp trailer arriving this month that I would like to outfit with a solar system that I would not have to rebuild anytime soon. I have watched several Will Prowse and Hobotech videos, and am thinking I want to do things a little different than most people do, but...
