I feel dumb posting this but I am perplexed after trying a couple online calculators. I’m helping a local/neighbor install a 6548, two server-rack 5kWh batteries, and twelve roof-mounted 300W panels. The solar panel cabling will have ‘losses’ and that’s ok. Initially used a calculator that...

I have been using this power inlet for several years now to feed my stationary RV. Quite happy with it. Recent acquisition of property naturally has led me to begin formalizing formerly temporary things. The L5-30 kit linked above enabled me to feed the 1012LV-MK for battery charging...

I’m pretty sure I’ve seen threads on this… coupla searches and I couldn’t find what I needed. Plan: “Stationary RV” - 25’ Camper- ~65 feet from my shop building 0ne conduit to contain six 10ga 120VAC conductors: two green, two neutral, two hot. One ‘set’ will serve generator output to camper...

I did something wrong today. I had to weld a couple small things and was about to plug into the generator when! I thought it would be inter-cool-resting to see what happened if I tried to use the solar system. I have a 2000W psw QZRELB/Reliable inverter currently sourcing from only two 140Ah...

Longish post. I think my plan is fine. Criticism IRL has me second guessing myself. Context: I have what most consider a ‘small’ system of currently/newly 2500W of solar panels. These are all home-runs to 4 SCC’s. I’ve always been a bit fussy about homeruns to avoid fire risk (resistance...

I am about to pull the trigger on purchasing an inverter generator. While this would be convenient for backup power, I’m actually purchasing it to run bigger equipment as needed. Most daily things I can successfully run on my 2000W inverter. The bigger, tablesaw, and the 240 V compressor as...

Bought a 3500W predator inverter generator with $100 off coupon. Haven’t opened the box as I’m having second thoughts. Noticed this morning that I can buy a “3650W” Champion for $50 less than HF price after coupon. But that’s not what’s most important to me. Which one is better? Champion...

I have tried to find anything other than create-my-own display panel for Drok meters. I have several in use for different purposes but I’m rebuilding the system wall to enable planned upgrades and wish to have a compact and “neat” means of panel mounting these displays. Here is an example of the...

I was fortunate to pick up forty-one thin film panels for free last night. Metered at sunset 75VOC which was not unexpected being closed to dusk. Panel labels say ~96VOC 1.2A imp, 60W, roughly 39”x36” which should yield ~8.7A charging, each, at 13.2V if they were new. I need to research it but...

Yours is the twin? Mine is the four cylinder engineering masterpiece that in race trim in the 1970s they would run at like 16,000rpm. No collector value for some reason but it’s cool. I shortened the blinker stalks, put a low euro bar on it (bmw style, not the low street racer bar), cut the...

New thread to discuss nuetral-ground bonding of a Reliable 2000W inverter to continue the topic without hijacking a separate thread. Posting here for lack of a better idea. Up in smoke?! Hope not? Reliable (QZRELB) 2000W manual states that bare/green/G cannot be connected for a bonded system...

I installed two Btr Power 140Ah 12V in parallel a week or do ago. No problems other than cloudy days which isn’t a failure of course. Charged fine with 4S2P 100W panels through the existing 1012LV-MK. Previously had charged 36+ hours to 14.5V to reach zero amps with a 10A voltage controlled...

This is about high C-rate charging of manufactured LFP batteries. Contents: I’m studying up before I do something stupid because I know enough to know what I don’t know; I snippet-quote from other threads I comment on the context I ask a few questions 1: @Substrate said: These threads are...

I have a weird thing with a long explanation post. If you don’t want the challenge in this problem just skip the post and move along. Solution is done but my posting here is for entertainment. Because technically this is a camper trailer (RV). 99.44% stationary, offgrid solar, “improved” for...

I’m a little surprised other people have not run into this need or desired this setup variable. I’m assuming that people don’t because my searches yielded little. To nothing. What about automatic transfer switches for 12VDC? One thread presented a good option for the scenario mentioned but it...

Setting the stage I have intentionally bought too many watts of panels not because I need the watts- but rather because I wish to have enough voltage to create usable charging in poor sun /overcast conditions. Overcast conditions are a consistent problem here in the Northeast Kingdom of...

Since santan and amarzon are indefinitely out of Epever 8420AN and eBay has them but $100 higher than above and other vendors had them a few weeks back. And with “shipping from manufacturer” (China) I’m trying to find a vendor with one. SNYOAW came up as a supplier with a quick-ish turnaround...

I am going to put my ~2kW of panels online at some point. I know most sunny days in winter I have been fully charged by 9-10AM with only 800W split direction array. With the cost of propane I have explored a couple of options to shave propane heat use this winter. A promising option...

I was researching a bit and watched Will’s vid on 280Ah cells touted to be the cheapest on allie and I noticed these voricorre batteries as one of the options in his affiliate link. Now I’m pretty good with a lot of things but I’m a diy LiFePo idiot. I like these bolt-together cells rather...

I have some 20V Porter Cable tool battery packs that were fine until they get dropped. I have taken a couple apart and I get voltage some places, not in others. Conclusion: likely broken welds (circuits seem ok) I’ve never welded batteries but I am looking at this portable welder which is a tad...

I have a couple 140Ah LiFePo batteries on their way. Ya, ya, ya, I know: cheap and maybe not dependable. I only see a few BMS failures- no other complaints and the price is right for ~3kWh of storage. I bought these: Now that that’s out of the way let’s not ramble into “should’ve bought …”...

It appears there are limited to no choices for 250VOC charge controllers below Victron, maybe Midnite, or Sigineer. No Epever, Ampinvt, or MPPSolar offerings? I just purchased six REC ~45VOC 315W panels new but 2016 mfg. just never installed. and hoped for 3S2P but my Epevers would...

I was offered a Solaredge 3.8 but from my ignorance in the gridtie sector I’m not certain I can use it. Key issues are: appears to be for microinverter use which I do not want. Can this be used with traditional panels in series or are microinverters with their built in SCC required? Is there...

I have an expired Office365 and I am averse to paying $100 a year for something I seldom use. I remember Apache had openOffice years ago; is that a decent option ? Looking for opinions from folks currently using that under Windows 10.

Not sure if I should post here or here: https://diysolarforum.com/forums/vehicle-mounted-systems.7/ My camper range hood fan works; it works fine- not great. I’d like to merely replace the motor with something a little bit stronger but in looking on Amazon the price varies but appearance and...

I bought the new Triron specifically for the 150VOC headroom. Then I read this: Now I know I don’t know everything but can someone make some sense for me head why/how the mppt range tops at 92V for a 150V controller?! I cannot comprehend this.

I can’t seem to locate the thread listing various inverter idle / no-load consumption. Think filterguy started it I’m selling my daughter’s unused stuff from her Sprinter project (she sold it) and a wzrelb aka Reliable 2000W pure sine inverter was in there. Naturally I hooked it up and measured...

My AN50 Epever cuts out while monthly equalize mode is active. I have a thread on my discovering of the problem. Before I just go all out and dump it for an AIO I thought I’d play games which gave me two questions- below. Today I adjusted some parameters that included moving Equalization...

I want to record the actual usage of my 12V solar and battery system. This device will do that but they don’t have the ‘ask a question’ feature. One review mentioned that it only records KWh in the ‘riding number’ direction. But I’d like to hear that verified. Is anyone using this device...

I have noticed- being that it’s very cold in Vermont this time of year- that running the coffeemaker sags my voltage down to where it triggers restarting the ‘boost’ on my Epever 50A SCC. Coffee is ~700W for 3-4mins; 60A draw Granted, it bounces back to mid-12s immediately after the coffeemaker...

A fun little experiment I did. Information and setting first, questions at bottom. In a slightly hijacked conversation we were having about atypical backup power using a fairly long run distance but reasonably low amperage I mentioned a thing I was going to try. Applicable to this subforum I...

In a recent thread the idea of ‘stealth’ or ‘guerrilla solar’ grid tie microinverters came up. Since I’d been thinking about that it prompted me to purchase one of these units and use it with some spare panels. Since then, however, I have been plagued with the fact that I have 800W of panels...

I have an AN50 that’s been working great. No complaints other than a broken terminal screw out of the box. EDIT: this thread has developed into solving problems with equalize mode which is apparently the issue. Latest posts (Feb2022) discuss my desire to get a fix from Epever I have a question...

^PIC: “open ground” lit (open N looks lit in pic but it is not) I have been reading with interest the several discussions regarding inverter Neutral - Ground bonding either present or missing. It occurred to me I couldn’t recall actually testing this on my inverter. I had ordered and received...

I recently got tasked to sell my younger daughter’s equipment left over from her abandoned Sprinter camper conversion project (truck is sold). One of the items is an Epever AN50. I had a brand new AN60 recently purchased and offered it to a guy who came to buy the AN50 (who thought maybe the...
