RE: Renogy 100ah LifePo4 Lithium - Max Surge Current

...... and we are ok with the 2000w PSW inverter we have now. Newer MWs will run on MSW (BTDT), but not this 1991 job.I would not buy any inverter over 1000w to be connected to lithium battery of 100 amp max current. Probably 800w max inverter for best results. I realize you have more battery but we are talking about a current limited lithium battery. My point was that AFAIK there is not any MW small enough for that, where a 700w is already 1050w for input. So Li does not change the basics same as Wet or AGM that you need more than 100AH if you want to run a MW unless there is a smaller size Panasonic inverter type you can run at half power maybe.

RE: Renogy 100ah LifePo4 Lithium - Max Surge Current

I don't think a microwave has much surge at the start. s/b easy to stay under 100 amps. Only real surge in an RV would be an air conditioner and that is not really a concern if you are limited to one battery. A "700w" Danby MW we had wanted 1050w input and made the 1000w PSW inverter pull 100 amps as seen on the Trimetric. The inverter showed its overload light but kept running. After a few times doing that, the inverter burnt out some components on its circuit board.You need a Panasonic 'inverter' microwave. Set to low power these actually draw less current instead of cycling the megatron. Yes, that would be an advantage for using a bigger MW that can hold bigger pots without pulling more amps via inverter. That 700w was too small. As it is the MH we have now has a big enough 1991 Dometic "RV" MW which will only run on PSW, and we are ok with the 2000w PSW inverter we have now. Newer MWs will run on MSW (BTDT), but not this 1991 job.

RE: Honda 2000I versus Cpe 2000 inverter

That link says what the X does somewhat. The regular 90's specs are given there too, but are not very clear. That 2200 is more of a gen than the 2000 for sure, and it must also do more than its rating. DLS 90 specs say 21.8a x 108v so that's 2354w but no mention of the 0.7 PF it has. Of course the Honda will be more like 123v doing the 90, which muddifies things. How can the 2200 do 21.8 amps?? Same power 2354/123v = 19 amps. 2200/120 = 18 amps, 1800/120 = 15 amps EDIT--2200 has receptacles marked 15A but have the slot to take 20A plug. (I haven't read the manual where it probably explains that) Output of the 90 is 1200w it says, but at 14.6v DC (battery voltage) that would be 1200/14.6 = 82 amps Doing it backwards, output at 90 amps with battery at 14.6v = 1314w. 85% efficiency makes input 1546w, PF 0.7 makes that 2208VA, so the 2200 gen at 123v would be at 17.9 amps. As usual with the converter specs you see, they don't help much. They normally understate the input requirement for the generator to supply by not mentioning VA and PF, but just the "watts" as though PF were 1.0 You do need a 20A circuit to run that 90 amper with its 0.7 PF. Same with the PD 80 amper. The PowerMax 100 amper (but not the 75 amper despite some ads that say it does) has PF-correction so it can have its 15a plug, but it is borderline for a 20A plug depending on if it will be continually run or just temporary by some NEC rule it seems. ISTR you can order it with whichever plug you want. Newer USA RVs have all 20a branch circuits with 12AWG wire so at least you are good there. Older RVs with 15a branches not so much. Note the new IQ4s you can get now with different charging profiles to suit your battery type. (like yours for the AGMs) There is also a special IQ4-X for the X models.

RE: Solar power battery novice question

This might be what you have: (scroll down to "dual bank") https://gpelectric.com/product-category/solar/page/2/ Lots to read on how the controller works in the "Products" links. If you believe that battery SOC from a solar controller, you are living in fantasy land. You need an hydrometer to check the SG for the real SOC. Also your own battery voltage reading does not give you the SOC unless the batts have been disconnected entirely for an hour or so (actually a day is more accurate, but an hour gives you a "close enough"). The controller does not know where its output amps are going. How much to loads and how much to battery. (Not talking about the "load" terminals--just the "battery" terminals which also have loads as well as battery) An actual battery monitor such as a Trimetric shows battery only. Even it needs to be calibrated (reset) fairly often using the SG with Flooded batts or its ammeter with AGMs.) In their blurb they say the batts are at 100% when they reach the high voltage set-point. That is false. That is just the start of the Absorption Stage. Anyway, you will figure it all out best by watching it work while camping. Just don't believe that SOC reading!

RE: Honda 2000I versus Cpe 2000 inverter

Just as a point of reference, my Honda 2200 has no issue pumping out all 90 amps using my Iota 90 amp charger. Verified using a Victron bmv712 battery monitor on my AGM batteries. It is not running at 100 percent, either. Do you have the 90 or the 90-X ? I see a typo in the 90-X where they said 30 where they meant a 20a receptacle. https://www.solar-electric.com/lib/wind-sun/DLS-90-specs.pdf I think it means the 90 and 90-X do not have PF correction, so expect 0.7PF. The Honda 2200 is rated for 1800VA continuous vs 1600 for the 2000

RE: Renogy 100ah LifePo4 Lithium - Max Surge Current

There are "inductive" loads and "resistive" loads, but also you get "in-rush" like with converters, and "surges" like with motors winding up. I got lost trying to figure out if any of them is the same thing as another. "They" do advise if your inverter won't run an inductive load at full speed, just add a resistive load like an incandescent lamp to the mix. That might only apply to MSW inverters, don't know. I don't know if that trick would help with an Li's BMS.

RE: Converter kaput need to buy better one.

Ok, so whatever you find out, we have lots of ways to spend your money! Having that big gen gives you many options. If the sun is shining while you do your gen recharge and you can set your charger volts to equal your solar controller volts, they will add their amps for an even faster recharge. It is handy if they are adjustable voltage so they can match their voltages.

RE: Converter kaput need to buy better one.

You have enough generator to run a 100 amp or even higher amp charger. A. What do you mean by "two banks"? Is this just the usual 4 sixes in series/parallel you can charge all at once, or some other set- up that you can only do two at a time? If so, why? B. If getting ready to do more off-grid, why not an inverter-charger? They come with up to 150 amp chargers in them, 120 amp is common. You can do that. C. Many prefer separate charger and inverter (me too),so you can still get a 2000w inverter and a 100 or 120a charger. (Again I like the PowerMax versions of all those, but there are other choices.) BTW, nobody questioned whether your converter is indeed toast. Are you sure, or should we get into whether it is toast or not?

RE: Converter kaput need to buy better one.

The RV's 30a has nothing to do with the converter size. The converter size in amps is related to the power output of your generator, measured in VA. A typical converter has 0.7 power factor. If your generator can run 1600w (VA) as its rating, then your input to the converter can be 1120 watts. Typical converter efficiency is 85% so output would be 952 watts. Output is in DC and you want 14.8v for those 6s, so 952/14.8= 64.3 amps. So you can have a 60 amp converter, but not a 75 amper unless you have more of a generator. I like the adjustable voltage you get with the PowerMax LK models so you can also crank it to 16.2v for equalizing the 6s every so often as , eg Trojan recommends. Nobody else makes a converter like that, and check out the price! https://www.boatandrvaccessories.com/products/powermax-pm3-60lk-12-volts-60-amp-power-converter-battery-charger-w-led-light You can do all four 6s at once with a 100 amp LK, but you need more like a "3000w" generator to run it. Maybe a 2500.

RE: Jayco TV antenna

On one of the videos (Jay Feather), if the antenna cannot be raised, it is wooded by the air conditioner. Luck of the draw if the stations you want are in the blind arc or not. If it is just stuck down, maybe pry it off (Eternabond where it was) and put it on top of the air cond. shroud. You can add a piece of coax to reach there.

RE: Honda 2000I versus Cpe 2000 inverter

Thanks! So that solves that part of it. I don't know what elevation Mr Wiz is at. Still a mystery about his various readings. IMO at least do a calibration check on the meters cross-checking with other meters. Also could confirm readings match the known wattages of the appliances. Beats me.

RE: Honda 2000I versus Cpe 2000 inverter

"... provide 2000 VA for the specified 30 minutes," Where is that in the specs? Thanks. (It didn't say anything like that in my 3000's specs AFAIK)

RE: IOTA Circuit breaker Box

You have a 20a breaker on the main panel for the inverter's output, but what is the circuit in the RV that the new breaker protects, and what is on that circuit? How does that circuit's wire (12AWG yellow supposed to be) also wire to that same new 20a breaker? Would the breaker when off be able to stop inverter power from getting to that circuit? Not like a Main and a Branch? Some folks use a sub- panel with circuits on it to run from the inverter. That way they can leave the converter, etc, on the main panel and not have that on the inverter. The 120v wire from inverter output to the breaker has a ground wire (bare copper) in it. That ground wire should go to the RV frame, same as the 30a Main breaker's wire does. Neutral goes to the N buss, Hot to the breaker. I have a 2000w PSW and a 300w MSW inverter. Both show two yellows (proper) with the three light tester in their 120v receptacles.

RE: Honda 2000I versus Cpe 2000 inverter

Thanks for the follow up. The key might be in this statement from a blurb about the Honda 2000i "•Honda EU2000i has 2000W starting power, stabilizing at 1600W continuous power" So just what does that mean? How long before it can't do 2000 anymore? My B&S P2200 claims it can do "surge" power for starting motors--"a short burst of power needed to start electric motors". It shows overload warning flashing red immediately with the 75 amper (converter has some starting "in-rush" but I don't know if that is a "surge")at 1700VA but keeps running with the red light flashing. Add a little more load and red goes steady and shuts down the 120v output. Reports on here that some gens with batteries in them for electric start can use that battery for an "assist" in keeping running at above running watts for a time. ISTR claims for 30 minutes with Yamaha gens?) Still unhappy with the inconsistent V and A. I will add more on here with an edit about that EDIT: Say the Honda unloaded is 125v. Loading reduces that in a consistent way as seen with my Honda 3000 and P2200 as posted earlier. Here we have: 115.5/17.03 115.5/17.09 123.9/16.89 122.8/16.xx 122.9/12.3 A 17 amp load cannot be both 115.5v and 123.9v, and A 12.3 amp load and a 16 amp load cannot be both 122.8 volts Is there a mix-up where the 115s are with the Champ? Something else going on here?

RE: Electrical issues

ISTR inverter-chargers require 12v to work at all, unlike converters which can work with only 120v. OP says he is getting fault signals from his I/C, so he is getting 12v to the I/C if that is correct. Where from? The shop screwed up (assuming they also put in the new batteries), so they should fix it.

RE: Battery Monitors

http://www.bogartengineering.com/wp-content/uploads/docs/TM-2025%20Users%20Instructions062017.pdf 98% for charging efficiency makes sense, based on what has been said. They do heat up some during a recharge. I don't like Bogart's idea of "full" so I don't use that to get a percentage SOC, but I still get lots of use from my Trimetric I got ten years ago. Others who know Li batts can answer the questions.
BFL13 11/28/19 07:58am Tech Issues
RE: Battery Monitors

Thanks for the additional info. No doubt that the Li batts are a good thing. I still don't understand how the percentage SOC can be at all accurate, but OTOH you don't need it to be. And I don't have to figure it out, thank goodness. I guess you "have to be there" to see how it all works. IMO Li does not change the general monitor situation that has been explained to the OP. In all cases, the monitor must be reset often enough using other meters/evidence to keep it from becoming off-kilter and giving misleading info.
