  • Post in thread: Why I moved to Henderson Nevada...

    I am from the south. my wife's family has a place in Quartzsite. I'll take trees, water and humidity over SCORCHING HELLSCAPE WITH NO SHADE. can you tell I'm usually there in August?
  • Post in thread: Lead acid cost

    LA is age old tech. I'm sure they hit the price floor long ago.
  • Post in thread: We have 24 Batteries for sale

    you need to list location, age, previous use, price for the whole lot. also its kinda a faux-pas to make your first post on a forum a for sale post. some forums require a minimum account age/post number to post FS threads. if you have seller feedback elsewhere you may want to dig that up.
  • Post in thread: How to charge the Ryobi 18v and 40v batteries directly from solar

    I've been soldering leads to the main pos and neg and charging with a mpt-7210a There's room enough in the case for a xt60 probably Battery hookup has some 40v packs for $6 right now. Get a dozen and learn.
  • Post in thread: Need Multimeter Choosing Help :-)

    just some cheap, tough meter for daily use. my "nice" meter is a fluke87 iii that I picked up doing some trading at a pawn shop. it stays in my electronics/soldering kit for the most part. my "beater meter" is one that apparently belonged to my wife's grandfather, found forlorn in a collection...
  • Post in thread: Solar wifi security camera

    How's your current wireless network? How's the land? Do you have LoS from your outdoor AP's to the area you want cams? I would suggest camera clusters, wired PoE cams with a wireless backhaul. Mikrotik makes good AP's, dahua makes good cams, and there are many small PoE switches with 48v DC...
  • Post in thread: Solar And Mini Splits

    I'm going to suggest getting the home's wiring futurproofed, you're gonna need extra breakers no matter what. go ahead and put a sub-panel in beside your service panel. take small loads off the main panel. free up at least two slots (one on each phase) this way you can feed the service panel...
  • Post in thread: cheapest place to buy panels ? and other questions?

    shipping for 20 panels from santan to my house in AL was $300. it would have been $230 if I picked them up at a terminal about an hour away. the panels, 250w 60cell, were $800. shipping was $300, in total it was just under $1850 for 20 panels, a mpp2424 and epever 30a delivered to my garage.
  • Post in thread: Anyone buy used panels from eBay?

    I delt with santan via email, they were great. I got 20 250w 60cells, a mpp 2424 and a 30a epever. I wanted 8-12 panels for my planned array. shipping was $300 to my place, $230 if i picked it up at a terminal. I haven't started the build yet, I have sold 9 panels to people with no complaints...
  • Post in thread: Design a portable battery bank

    see lithiumsolar's "diy solar generator" build on youtube (and its followup), it's a great blueprint for any type of those builds. jehu garcia did one using one type of phone batteries
  • Post in thread: cheapest place to buy panels ? and other questions?

    panels are hampered by logistics. try to find local sources. I wound up getting 20 250w panels for $1100 shipped from santan. if you want cheaper lithium, look at the diy lifepo4 battery sub-forum. you could probably get triple the storage for the price of two BB's. maybe order 20 cells...
  • Post in thread: Where did you come from/where else do you go?

    I quite literally grew up on the internet. from a kid in the late 90's to today in my mid 30's I've left a mark just about everywhere online. main drivers were the search of knowledge or piracy. the big factors in my teens were: irc, direct connect, icq/aim, hardOCP (leaving around the time...
  • Post in thread: Off Grid LED Lighting

    I use 12v LED strip everywhere possible. mount it where your eyes can't see the LED's. 5050's will use more energy than 3825's, strips with 60 led/meter will use more power than 30led/meter. you should dim them with PWM and not voltage, but I do typically run the ones I deploy at work at 10-11v...
  • Post in thread: I ordered 20 250watt panels and other gear today.

    I finally put my money where my mouth is. today I made my santan order: 20x 250w 60cell panels 1x mpp 2424lv 1x epever 30a mppt controller I plan to mount 8-10 panels on a old boat/utlity trailer, this array will have the MPP on it. I'm going to start with some rural king golf cart batteries...
  • Post in thread: Using excess power

    look up "diversion load" -- you could possibly use that as a template to do what you want to do. you may want to post your battery capacity, how soon your bank is fully charged on a typical day, pump watt draw, blah blah you could get a low voltage disconnect and wire it to the pump, set it to...
  • Post in thread: Cinergi's 28 kWh / 4 kW Solar / 10 kW inverter RV build

    my plan is basically a mini-version of yours. 1997 diesel pusher MH, I am using 32x 120ah cells (I have 48), chargery 8t's, and am strongly considering victron inverters I replaced my progressive 12v80a charger with a mpp-style AiO 12v inverter/mppt controller/ 20a grid charger. I went with a...
  • Post in thread: Temco lug terminal crimper

    Just got this $61 crimper in. Seems to be well made The wire is 5g and lug is 4 in the pictures
  • Post in thread: Determining correct bolt on fuse size

    You fuse for load+20% or so OR the maximum safe amp rating of the wire, whichever is the smaller number.
  • Post in thread: Off grid refrigeration

    I agree, for people without size limits its just better to vastly oversize your system. gives you the flexibility to run unexpected large loads like saws and microwaves-- if budget allows you could even build big enough to run a mini-split for heat pump/ac/dehumidification. even RV'ers are...
  • Post in thread: Idea I had this morning with wifi power strip I converted with Tasmota flash..

    sorry, I can't give traffic to a website that supports alex jones, anti-vaxxers and the like. do you have it hosted anywhere else?
  • Post in thread: My New DIY Portable 400 watt Solar Generator (with pix)!

    If you have a 1/2" impact you can use huge lag bolts. Makes the process much easier. Idk about you but I always carry my impact on road trips. Makes changing a tire trivial.
  • Post in thread: All-In-One - Is A Battery Required To Use Inverter?

    to preface this: batteryless setups do exist, but I haven't looked into them. my plan for my first build (all parts purchased and delivered, working on building a structure out now) is to use a small battery bank as a buffer with a mpp all in one. the setup will be 8-12 250w panels, a mpp 2424...
  • Post in thread: Love this Dual Fuse. Any reason why everybody not using it?

    Regular car audio fused distro blocks are cheap and typicaly use anl/mini-anl fuses Examlle that I have not used: https://www.amazon.com/dp/B078SCQJNM/
  • Post in thread: MPP solar is Garbage from E bay

    Nope. If that laptop dies/gets replaced I can spin up the VM in a few minutes. Ideally it would be pushing a nightly backup to my nas. In my opinion, unless you have a physical hardware reason for it (hardware dongle, no vt-d support), nothing that you rely on should run outside of a...
  • Post in thread: Wire crimping tool

    hfqpdb has them all
  • Post in thread: Temco Lug Crimping Tool

    I got the first one linked and really like it. once I get a few dozen crimps I'll post firm opinions about it. I wish I had bought one years ago when I got into car audio.
  • Post in thread: What is the best way to charge a 12v lead acid bank from a 24+v LFP bank?

    that reminds me I need to do a post about the fire extinguishers I snagged from ebay seller pjfireco a while back. I do some flame effects and pyro so having refillable extinguishers around is comforting.
  • Post in thread: SLA Battery Banks to all in one converters?

    ***links are for example purposes only. not endorsements of any specific product or seller*** if your batteries are top post only you'll need some terminals, maybe like these (idk that seller) -- you'll also want some distribution blocks. keep your wiring runs as large and short as possible...
  • Post in thread: Aoyue soldering irons

    there's a ebay seller with custom battery holders for them, I'm sure you could have some 3d printed locally though once you build a pack, you could look into a TS-100 iron for mobile use. be sure to document your builds here. I need to build some rechargeable path/boundary lighting for...
