230VAC all-in-one + Step down converter -VS- 110VAC all-in-one?

I'm wanting to put together a 48VDC MPP Solar 5000 watt all-in-one system, and in looking at the options, it seems that the "230VAC" versions are not only cheaper, but have more of the features I'd like to have; bluetooth, remote LCD, etc.

So, as far as I can tell, I would save @$500-US going with the 230VAC (MPP Solar PIP-5048GK (230VAC) and a step down converter ELC T-5000 5000-Watt Voltage Converter -VS- the MPP Solar LV-5048 with 110VAC output built in...?

My question to the much more knowledgeable folks here is:
Is this a dumb idea? Will there be a ton of loss in the step down transformer? Anything else I should be considering?
Any and all help is greatly appreciated.

I like the idea. I have also stayed away from the all in ones for similar reasons. My questions would be to make sure the MPP and the transformer are the same phase. I also saw where it said not recommended for things like coffee makers so make sure your usage will work with the transformer.

Im interested in others thoughts as well!

I think using 230V Asian/EU model is not a great idea in NA.

1. It's adding a point of failure in the system when using step down transformer. The reason we want to use All-In-One is for simplicity.

2. The step down you posted is only rated for 2500W continuous usage. You may need two, and thats about $300

MAX - 5000 Watt for 30 Mins Use. For continuous use: 2500W. Make sure you multiply x2 the wattage of your item and get a transformer bigger than that.

3. $646 + $145 (shipping) + $300 = about $1100
why not just buy LV5048 for $1300 and its local US shipping with local warranty?



I am currently own a LV2424 and it's great. I use for not only induction cook and but also pressure washer with 8 6V Costco GC2 battery ($90 CAD each)

Both good points. Thanks for the replies.
In keeping with the "Keep It Simple Stupid" montra, and expansion potential, I went ahead with the LV5048. Should be here in a couple days!

Now I just need a charge profile and BMS for two Tesla Model S battery modules. Any suggestions?

be aware in the custom settings, the battery cut off voltage is 20V as lowest, when grid available is 22V

charging to 90% is about 24V for Tesla battery

Tesla battery can go down to about 18.5V, recommend is 20% @ 19V

so by using MPP, essentially you can only using <60% of the battery (about 3kWh)

it's true Tesla battery still cheaper and better capacity, but they are not playing well with standard equipment, which is painful

The LV5048 is a 48V system, but yes, I see what you mean on setting #29 page 19 of the manual where the lowest setting is 40V, but then on page 28 it shows a Low DC Cut-off Voltage of 38.4V, which is what I was focused on, but I may be misunderstanding that. I wonder what the reality is.
