I have not selected a charger yet. Still looking into the AIMS 75a as it can do LifePo4 too. I bought a Uni-T UT210E DC clamp meter that has a nice low 2A range. The RV/Bus has less than 10ma of system drain which is very nice considering its got 100s of connections relays breakers and stuff...

I have done one and only one group buy using the above group buy. For me it worked out well but apparently I was one of the last. Sad that Will has had to clamp down because I fear a side effect will be a bit less vitality on the forum. OTOH it was starting to get a little "noisy". I am...

So did anyone actually MEASURE the AIMS drain when not plugged in?? Just curious as I have a cheap charger that destroyed a good battery set for this very reason.

I totally get what your asking here but as you can see from the responses your not likely to get concise answer. The best resource Ive found is still some of Will's videos. He swats away the nonsense and directly answers the questions. In fact, for a first time setup Id probably choose one of...

Ah ok. I was hoping that L2 ground was selectable.

I'm thinking if high current loads like AC, coffee pot, microwave are 220V euro the 120v transformer can be fairly small reducing the "core losses". Obviously the transformer needs to be protected by a suitable breaker like all loads. More questions. Do the 220V euro inverters float the...

Can you comment on the idle/parasitic draw transformers place on the inverter? Do some designs have lower idle draw than others?

Heres some points Ive noticed in this thread so far. > 220v inverters are more efficient at load than 120v (lower current loss) >Auto transformers are kind of dangerous but seem to be efficient. >Isolation transformer is safe >Isolation transformer is much larger for same VA >Transformers...

Ill be looking for some similar 3phase solution soon. In my case 3phase grid power is not an option. While there are many inverter systems than can function in 3phase mode all I have found must stay in inverter mode. That is they CANNOT take two phase 240 and pass through as 3phase. The...

My workshop has 220V split phase power (USA). Im have a nice area for Southern facing Solar array however I need to also provide three phase power for some sensitive equipment. There are some commercial three phase converters running about $5k but of course no solar or battery ability. I...

Real inverter units compressors are three phase and constantly optimize voltage/current phase for load. Very little wasted power.

Ah good point! This goes double for mobile minisplit installation then.

The Alibaba site has some prices. Not sure if I would want to bury one of those in a wall or roof though.

Close to 1k about a 1 1/2 years ago IIRC. Currently the 35 foot coach is broadside to the full sun. I made bubble wrap window covers for most windows. 9k could handle it except for roof insulation. The old insulation provides little protection. Having roof solar panels would help a lot though...

Thanks on the panels. Im guessing they are harder to make than it would appear since Vans/Buses have such limited insulation area. Some casual searching has not turned up much in the way of DIY VIPs.

What about the flare sealants? Will these improve the situation?

A bit old post but Im testing a 9k Mr Cool in a 35 Grayhound in 100+ Texas heat. I find here that NOTHING matters more than insulation. In fact, insulation is by far a bigger factor than any SEER/Solar configuration. This is such a big deal that Ive started looking looking at these so called...

A DC-DC charger look like the only way to go with modern charging systems controlled by the vehicle ECU even though they are somewhat limited in power. But if you have an older vehicle with conventional Alternator/regulator you may have more options such as running a 24volt alternator and...

I wonder how these respond to over current conditions like charging Lithium chemistry. If they are constant current up to the voltage set point then running in parallel might work. Perhaps use an SBMS0 board to put them in standby until needed.

Whats the idle draw with these little boards?

Oh right, yours actually has a lot more sensitive systems I imagine. Is your chassis 12v or 24v?

I get the current limiter but why the desire for galvanic isolation between the two systems?

Sterling and an interesting pro-split battery isolator however Im not sure if its designed for the lithium voltage range

Its a 1964 GM 4106 parlor coach with the 50DN style alternator. The original AC is removed but Im planning on installing a modern system in its place although somewhat lower capacity. Originally the 4106 was 12v but I converted it to 24v. It was a big job with all the details but the large...

Looking for a 100am 24-24 boost/buck charger to solve a design problem. Ive found a Victron unit but its really designed for the smart alternator systems. Anyone know of some hi amperage alternatives? This bus has an oil cooled 250 amp alternator designed to run cntinuously at rated output...

Since its designed for auxiliary duty and has an intergrated regulator the details should be available to find out where it gets its startup power(some are self exciting) and if it has a temperature sensor as well as its output voltage at various currents and temperatures. It may have a remote...

Yeah that's kind of true but rest assured, America is getting thoroughly bashed in China too! Besides Ive found that bashing the bashers is like beating a growling dog. Its too easy to become part of the problem. I grew up in the 60s and remember well cheap American made products. Ingenious...

The problem is not whether they can make good products. The issue is they cannot make consistently high quality products significantly cheaper. But, most of us are willing to roll the dice since we are not relying on these tools dayin/dayout to make a living. Where you can get into real...

Just wondering what your results were on testing this unit. Did it meet your expectations?

I know this is an old thread but recently read an article on linear compressor tests. In that article 53Hz was the optimal efficiency point. On either side it drops off. But its still way more efficient that the stop/start of a conventional compressor. Seems the linear compressors have had some...

Or cold ones too! Retains heat.

The new norcold in my RV conversion is great if your in cold weather and have propane. But otherwise its got to go. Anyone have experience with the LG linear compressor? This 6.9cuft LG LRONC0705V does not have a fan and should be efficient with the linear compressor vs the 1950's induction...

This seems to have the samsung linear compressor: LG - 6.9 Cu Ft Single Door Refrigerator - Platinum silver Model:LRONC0705V SKU:6452360 Any opinions?
