RE: Westinghouse i4500 Generator

Itinerant1- no, I don’t have soft starts. That may be in my future, but- * I can start and run an AC fine using batteries and Magnum alone, static current draw ~180A with sundry other draws * Magnum doesn’t appear to be playing well with my generator (now 2 generators) * i4500 should have plenty of guts to start the AC but the Magnum kicks it out and doesn’t let it bring AC up on own * If I put magnum in load support, or start on Magnum and then try and bring genny in, it Overload Faults and indicates about 400A draw ******Occasionally I have started AC with inverter off and with inverter in load support by playing combinations of manually soft starting, varying VDCO, dropout voltage, etc but it’s’hit and miss’ with success ~10% at best I have a call in to Magnum tech support, I really think there’s an issue with the way it ‘qualifies’ the incoming power and/or sync’s with it.

RE: Westinghouse i4500 Generator

Itinerant1- Thanks Good news is I changed 3 things this morning (AC input from 22A to 27A, LBCo from 10 —> 11v and Search from 10W to OFF); it was mid 90s out after church and it fired up like a champ: without inverter support being on, and with charging on. Ran for 3-4hrs with one AC on, brought SOC up from 60% to 95% and kept coach in low 90s on the one AC while outside temps climbed to 103deg. Genny power was pretty consistent at ~3.24kW for most of the time, tailing down to ~2.3kW towards end as batteries mostly charged: powering charger, 1 AC, and the low fan on the other AC (no compressor)). Bad news is I decided it was time to experiment and learn a little :( * I turned off the charger, genny power to ~1.8kW; turned on the inverter support; and attempted to start the second AC. Inverter kicked out the genny and faulted. Worse, is now I couldn’t get the genny to power any AC!!! I played for 20-30min trying to start AC on just genny, with inverter support, on inverter and then trying to bring genny in, with charger on and off and anything I could think of. Once the genny over current faulted and took itself out, but all the rest of the times the inverter would kick the genny out or not let it in sometimes faulting itself. Temperature is rising and I’m kicking myself for messing with it. Finally looking under inverter tech section on faults I noticed Vdc was at 10.5 during last fault so I moved cutout down to 10.4v and next attempt the genny started and ran the AC (without going slow - fan, then compressor; and without locking the charger out. At this point I’m running an AC again and not messing with it any more today. Tomorrow AM I’ll call Magnum, it sure seems like their “qualifying” of genny before/as switching it in is somehow not playing well with the generator and AC surge. Unfortunately I didn’t put an inverter bypass in when I installed the Magnum so can’t take it completely out of the loop. Greatly appreciate your thoughts and help. If you have any other ideas I’m all ears, but doubt I’ll risk loosing AC again today :)

RE: Westinghouse i4500 Generator

Itinerant1 - I noticed that too. I did that to try and allow the genny to work through the surge at the advice of the Magnum tech a few weeks ago. I’ll play with it some tomorrow. It sounds like yours behaves as I would expect, namely you can set input amps wherever you want and Magnum boost will seamlessly take over above that. For some reason my Magnum seems to be rejecting incoming power because it’s falling before it takes over.?? I’ll mess around tomorrow and hopefully comparing your setting will lead to a solution. Thanks again !

RE: Westinghouse i4500 Generator

Bob213 - my Magnum inverter is feed from the shore umbilical and then feeds my whole RV through the panel. I tried starting with the inverter off, but no go there too. When the inverter is ‘off’ it passes through 60A per leg, but it still has the voltage integrity checks etc. I’ve mess around some more and now am starting to think that I might have been too cute trying to limit the input current and have the boost take over. I’m thinking that it may be the input current limit was kicking in and not letting the genny do it’s job. And for some reason the boost function isn’t just additive to what’s coming in but instead might somehow be kicking out the source for another integrity check and then getting in a loop. I’ve now upped the input limit to 27A (altitude based output of the genny) and it’s been running fine for quite a while. Given I’m getting cooling I’m done messing around tonight. Tomorrow I’ll try restarting with these settings, maybe even take input limit up to 33A (generator boost capability) or higher and let genny take itself out of the loop instead of Magnum dumping it out. I’m hopeful that that will resolve my issue. Still don’t understand why Magnum boost doesn’t just add to incoming without forcing integrity check if that’s what it’s doing. I’ll mess around some more tomorrow and maybe call Magnum support on Monday. Thanks for letting me think this through on-line…and for any suggestions still to come Ron

Westinghouse i4500 Generator

I posted a few weeks ago about trying to run my AC with a Yamaha 2k genny and Magnum 3000W boost inverter. Sort summary - the Yamaha just wasn’t strong enough with surges to work. So now I’ve purchased a Westinghouse i4500 which we just picked up today in Salt Lake. It’s 100deg out so I expected I could run my AC, maybe both ACs with the boost inverter…no joy :( Altitude here is 4200ft so I don’t expect the full 3.7kW static performance but still it should start and run an AC!??!! By playing around with Magnum control settings I can nurse the genny (with Magnum boost support) to start one AC once in a while (Magnum VAC dropout=60v, AC input limit=20A; manually start AC fan on low early; etc). Still have to futz with it a dozen times or so to get success. When running the Westinghouse shows it’s providing 2.3k power (AC, fan, converter). But even when I nurse it up on one AC it only ran an hour then kicked out, a half hour the second time. Just spent 10min getting things going again, hopefully longer this time but we’ll see. When it kicks out the boost inverter takes over and keeps the AC and fan running by drawing about 170A from my batteries. Not sure why genny kicks out as it doesn’t show overload, just reduces to 0power and the Magnum timer to kick it in starts dancing with the genny but it doesn’t ever come back in. As I’m typing, the genny just kicked down to 1.3k power and my Magnum is supplying load support of 50A from batteries for a couple minutes; then genny went back up to 1.7k and is running the AC on it’s own again. Anyone have a clue what’s going on, and why the Westinghouse can’t start and run an AC on it’s own?

RE: 12 volt AGM battery

Toed toes - last I looked Optima’s weren’t’cheap’ batteries. For about the same price you could get Lifelines that come with lots of technical info backing up performance expectations. https://batteryguys.com/collections/lifeline/products/lifeline-gpl-27t

RE: 12 volt AGM battery

Lifeline. They are not cheap, but last and perform better than cheaper ones. If you only want a battery to last 2-3 years, or want to run them down to 11v, then just buy the cheap ones. If you take care of them and want them to last 10yrs, Lifelines are worth it. On the other hand, if you REALLY want to spend $$$$, get lithium’s :)

RE: Filling the water tank at home

Swimmer spe - I’d consider UV disinfecting and adding fluoride “treating” the water before it shows up in your tap… https://en.m.wikipedia.org/wiki/New_York_City_water_supply_system With that said, we’ve kind of taken this thread way off topic. To get back to OP, I always use an in-line filter for any water going into my 5er tank. Additionally, when we used to have a private well, I used to add a small amount of chlorine to my tank from home if it would be sitting more than a few weeks.

RE: Filling the water tank at home

Used to drink water straight from lakes in BWCA in late ‘70’s (took from below surface)…but by early 2000’s it was recommended to filter it before use. Backpack filters are a pain to use, but we never got sick…which would be more of a pain. I too am a little surprised about lake source for drinking water Then you won't want to learn about where and how NYC gets it's water. LOTS (most?) cities get water from lakes and rivers, but pretty sure it’s treated before it shows up in your tap. Pulling drinking water directly from surface sources is what surprised me…

RE: Duramax Turbo

Sounds to me like it might be a.problem with the ECM, another turbo after only 8000 miles is to me unlikely. Agree it’s very unlikely the turbo (think that $3500 was wasted :( ). Other than ECM is there anything else that might be suggested? Saw one comment on another site about maybe MAF sensor? Anything else? I’m going to have to spend more $, I want to nail it this time!

RE: Duramax Turbo

OP here after a couple years on this thread. Short summary is that my Duramax started throwing P2599 codes about 125k mile (hence the thread). Since then I ended up replacing the turbo at 152k miles (last Feb). Now at 160k miles I’m back to the same problem. Pulling heavy this morning I went into limp mode twice in the Rockies. Both times I cleared the codes and kept going. Any ideas what service I should look at next?

RE: Yamaha 2000iS and softstart with AC?

I have 630AHr Lifeline AGMs connected with 4/0 throughout, batteries have no problem supplying 400A. Even though it’s momentarily, I’m not happy driving those type currents in the Magnum 3012, nor the ~35+A that implies to the AC. Necessary to start, but oscillating around those numbers can do real damage. As stated, I need a bigger generator, period. My 3012 boost capability is great when plugged in to 30A as it allows me to run two ACs, misc light stuff and not pop the breaker when my wife turns on her hair dryer. I expect it will do the same when I get a beefier generator too.

RE: Yamaha 2000iS and softstart with AC?

Itinerant1 - watching the arc50 battery current draw is how I saw those numbers. I don’t fully understand why starting the AC when the generator was on and Magnum3012 in load support showed numbers higher than when I started the AC just on the 3012 without the generator involved. I suspect some of the issue is sampling, as well as syncing behavior of the 3012 as it attempts to titration current with the generator involved…but I do know the generator was bogging down during this as was the AC. With that said, I tried it two or three times and got similar results: arc50 shows +30A or so charging batteries from generator; AC turned on and current swings momentarily to -400A 12v current or so, oscillates briefly then 3012 kicks generator out and settles down to -180A (had some lights and other things on) running AC fine; after little bit 3012 tries to bring generator back in (still running) and current jumps back up to -400A range again. After a few sequences watching this oscillatory behavior I chose to run AC off of batteries alone for an hour or so (it was HOT out) but didn’t want to subject my AC to any further experimentation. I discussed all of this with Magnum tech support and their only suggestion was to lower VAC cutout voltage allowing more time for 3012 to establish load support instead of source replacement…again, I’m not inclined to continue experimenting to the detriment of my AC. I’m convinced my Yamaha2000iS just isn’t the generator for the job

RE: Yamaha 2000iS and softstart with AC?

I would only add that though the generator may struggle a bit while on Eco, the transition time for load switching is typically stated to be approx 16 milliseconds which equates to approx 1/2 of a single sine wave, so in the grand scheme of things the transition happens fairly fast… 3 tons Not fast enough to keep Yamaha2000iS from bogging down and sending the system into oscillation causing 400+A draw from batteries (and not doing the AC any good)…

RE: Yamaha 2000iS and softstart with AC?

The answer to my initial post is clear, I need a more robust (and preferably larger) generator. I errantly expected that my hybrid inverter (on board, not to be confused with the inverter generator) would just make up the difference between what my AC required and what my underpowered generator would provide. The reality is that the older Yamaha 2K generator can not deal with surge currents (or in-rush, or how ever you want to define motor start up required current), it drops voltage as a response too quickly to play well with the hybrid inverter. Consequently an oscillation is set up between the sources instead of complimenting each other. I momentarily witnessed 400-500A being drawn from my battery bank! Not good for anything in that path including the AC!!! Prior to starting this thread I’d already discussed the situation with Magnum tech support who suggested (as did otrfun) lowering the VAC dropout to help eliminate the oscillations. Not a solution I’m willing to attempt because of the large current stress that would put on the AC. Bottom line, my generator is too puny. If it would act like an ideal voltage source just limited to 13A, or 10A or whatever, my hybrid inverter could make up the difference and I’d be happy. The Magnum is very capable of starting and running my AC on it’s own I just don’t want to be drawing 200A from my battery bank for hours instead of minutes. My hopes at a cheap/quick solution (softstart) we’re naive, I just need a bigger generator to run AC. I’m sure that a 2200 Honda would marginally work, but if I’m spending money anyway I’m not going to cheap out on the right solution (like my initial question was pondering…
