- If you had no power , and just a few panel and no batteries, you would still be able to power and run the basics just off Solar.
We review the output capacity running with only the Sun (and then a few batteries)
The LVX6048 is a great unit as a stand-alone all in one Solar Solution for Off Grid and On Grid users alike.
It also has powerful features for time of Day (off-peak) Utility charging etc.
It weighs a hefty 87 lbs and is designed if needed, a battery capacity of at least 48V 250ah (12kWh , but 30kWh of battery recommended)
Pencil resistor to charge the caps.
Brilliant! 😆
Looks like a decent inverter for the price. You should invest in a proper splitter for load testing the AC output. That cheap power strip is a joke. I would like to see if this inverter can start a 4 ton condensing unit with a soft starter on it...maybe 55A surge @ 240V for 1 second.
I would be very interested in that also
Thank you! Great video. Still setting up my LV6048 and SOK batteries. Solar panels are next.
Incredible load test on this Low Frequency inverter that for sure to run high amperage power tools on both legs without it tripping or shutting down especially with 48 v DC and the PV modules keeping the power steady . Great video for all preppers who May be in serious solar and also likeing the video .
It would be great if a vid could be produced to show the relationship between locked rotor current LRA of a motor, and it's class and how this relates to the output of the inverter, and battery BMS capacity.
Starting a 240 volt compressor class B motor compressor can produce 25-30 amp peak inrush current.
The 6048 may be maxed to meet this, and the battery BMS output may require two or three LiFePO4 100 Amp in parallel to not trip out on start.
A vid showing the calculations and sizing would be very useful especially since off grid typically also means deep well pumps, table saws chop saws etc
The issue with the LVX to me is the standby power consumption.
I am researching separate Low Frequency (Aims) units that could be left off when not needed to run my shop equipement (Table saw, Jointer, Dust collection, Planner etc) since I don't need the standby power consumption chewing up power when the shop is not in use. A separate subpanel just for these high inductive loads would seem to be the best option.
A test on a 2.5Hp 240 volt (7.5 FLA, class B motor) air compressor showed peak inrush current in the 25-30 amp range (!) although only for a few seconds.
One option is to run a heat pump water heater with a batteryless system, and turn up the temperature a few degrees to capture more energy. In this use case, the water tank functions as your battery and is plenty to shower with -- especially for those in a home of 2 occupants who tend to shower at night! There are also ways to store heat for warming the air (look up the Sunamp heat battery) provided you have a very well insulated building.
Can’t wait to see the WP version in a video. Great info as always Ian.
It is here already. It is called the Sol-Ark or DEYE, MPP is using that technology / licensing the WP version from DEYE.
@@zekeboz5533 Sol-Ark is no doubt twice the cost??
@@zekeboz5533 ooooohh, wow really? Deye has a patent on it? that explains a lot....and mpp still can't get close to getting it to work according? odd..
As long as ive been researching solar power for off grid applications i cant believe im just now finding all of these inverters that dont require a battery system. I mean batteries are very convenient but a 6kw power source during an emergency "like a month long power outage" would be awesome even if its only for 4-6 hours a day. That could literaly save peoples lives. Then when you add the batteries, this unit could easily power a small home if done correctly.
I've been Off-Grid for a couple of years using an even smaller stand-alone unit from MPP Solar, the MPP-5048MG ,which is the 5KW predecessor of this 6kW controller. At first I tried it as a UPS, but because the controller had the Neutral bonded to the chassis ground internally, I stopped using the grid as AC input. Since I uses a 5KW step down toroidal auto-transformer to create a split-phase out of their 240VAC output. I did checked that it indeed could be used as a battery less inverter but there is no advantage to do so if you're going fully off grid. That's because you need power at night and only batteries can store electrical energy at night. So I started to build up my batteries banks slowly over the years to 70 KWH now. That's actually about twice what I need to power my whole house. But I wanted that extra power to feel less anxious during the Winter time when the weather goes bad for several days in a row and the days are short.
Ian as I own this unit I've made a general search for all UA-cam videos concerning the lvx 6048. That said your videos is one of the most complete videos I have seen. I especially appreciate the fact you've done close-ups on the connection board at the bottom of the unit!!!
I must admit I was under the impression I could charge it with my 110 generator. Needless to say I'm surprised I can only charge it with 220 volts. Thanks again for taking the time to create this very informative video.
Yeah, that sucks. The LE4 and other similar internal units seem to be the same way.
@@TheBlairHouseProject in the event I need to charge my batteries. I'll just do it outside of the unit. In other words I have an Aims 75 amp (the amps are variable I can take it down if necessary) although with a 48 volt lithium battery setup. It's my understanding you can pump as many amps into lithium as you want to charge and plug into a 110 outlet.
How is the LVX6048 treating you these days? Have you had any problems with it?
@ahuggins6 Actually my plans changed. I still have the unit in a factory unopened box. Looking to possibly sell it. Everything I've seen online speaks positively about the unit.
@@wideawaketotruth5301
Do you still have it? If so how much do you want for it?
It would be very interesting to see your thoughts/methods for setting this up with two or more units as I think many will take this approach
Agree code [09] how You fixed
that is the only mpp inverter i would buy but it likly has high idle amp there is a few low freq inverters with low idle i like this guy on video he speaks truth
If the unit can manage power sources that well then I imagine it would vastly improve the life of the batteries. Things are developing so fast in this space even after only 3 years after buying my set up. I will be watching to see how its longevity goes....
How Is it going so far?
this channel should have more views!!! amazing tests always the best
I also am signed up on your site for a ping when the WP version is available. Thanks Ian!
Nice, mines run 24k btu AC and grid export on
Finally an overview of this inverter, thank you. Can't wait for the WP version of this
You and me both!
WP?
@@aaronrunkle It’s the UL waterproof version coming this fall. That unit is going to sell like crazy.
Ian, let us know when you will be taking pre orders for them
Hi there, I have a question about how to hook up the LVX6048 MPPT Solar Inverter to the utility and home panel. May I run the utility power to the AC input and then the house panel into the AC output? Please advice. I have 48V bank batteries 12 batteries 12V 75Ah in series and parallel. What do you suggest? I want to charge my electric vehicle in my garage where the utility power panel is located. I have 12 440W solar panels in series and parallel. The project is under construction now. Please give me some advice.
I'm worried by the time the WP comes out they'll be impossible to buy 😔😪
Excellent Review..!!
Thank you so much for the little details
I would like to know if I can use the AGM battery and LiFe-PO4 in parallel on 24 or 48 Volts
hi Ian, i was curious if this would work to a hot water heater direct as its batteryless.i have 3k watts worth of panels i want to use with it. thanks.. it would drive one element of the heater
Another excellent video Ian!
Glad you enjoyed it
Where can I get a owners manual for this unit?
Nice video
Is the transformer an isolation transformer or midpoint transformer ?
what's the difference?
How did you arrive at this number: a battery capacity of at least 48V 250ah (12kWh , but 30kWh of battery recommended). I looked through the manual and could not find it.
It's weird. I don't get anything across L1 to L2. I get 120v from ground to L1 and N to L2. I don't know what is going on.
Hello, have you tried it on NETWORK INJECTION, thank you.
Did it come with those 2 big gray connection points for the PV input?
Mine acquired 3 months ago had much weaker attach points
That is pretty amazing.
Can this inverter be AC coupled with a SolarEdge 6000 Grid tie system? Does it have a mechanism to shut down the SE solar once the batteries are full? Can it be programed to perform electric rate arbitrage?
Does this inverter create RFI?
Ian how do you reboot it? Mine went off in the night. battery is full but no power in house. If i turn on power it runs but no in house power.
Hi Ian,
I would like to buy this solar inverter LVX6048 but I want to know if I can put in a series of 5 x 48V solar panels and use 12 batteries 12V 75Ah 4 in series and 3 rows of batteries in parallel. Do I need the 6 String PV Combiner Box for Solar Panels or NOT if I am using the solar panels in series? What about the batteries that are enough for the 4 or 5 solar panels 48 V 440 W per panel.Thank you
Did you try Menu #30-31 Utility charging, not working on mine.
How objectionable is the low frequency hum? Can not hear from your video. Others have made comments from extreme to hardly audible.
Can anyone tell me the brand name / model number of the combiner box?
Nice video i I love. How much is the sistema complete 🤔.
Hello could you explain how someone could get split phase if you parallel two of these LVX6048 together? For the LV6548 it is easy because one hot from each inverter AC output ( Therefore one hot from the one unit fed 120v for one leg of the panel the other fed the other 120 to get split phase. In this one your have 2 hots from 2 inverters. How will you go about wiring these?
In the case of each inverter covering each respective leg, they still have to be in sync so that they are exactly 180 degrees out of phase. I’m this case they have to be exactly *in* phase.
I will like to see how you program the software
i just saw some one ON you tube back feeding to the grid OMG he thank s it.s a grid tie and he is saying the inverter is junk
Better to stay off grid 😉
can you determine whether the LVX6048 AC output is truly split phase ? or via an isolating transformer ? or an auto transformer ? the apparent increased weight implies a transformer of some sort. Thanks
auto transformer with 120W idle consumption as reported by WP.
@@errcl65 wow! is this inverter safe because I saw some other videos about autotransformer's connected to inverters?
Can this inverter handle over paneling like putting 8000w total panel so it can produce more durring cloudy days? Thanks
yep, I over panel my little Goal zero 3000. It has a MPPT charge controller with 275 watts output, and I have 800 watts of solar panels on it. Works so good even in clouds.
Are you hook it grid-tie mode?
How sensitive is this to putting all the load on one leg of the 120? Can it handle all wattage through one leg?
That will be my next video test, was thinking the same thing
I would think 3000 watts per leg because more amps is more heat in the inverter.
Hi
I see it can parallel.
But you did this can you get 3 phase . ?
I guess you have some 3 phase appliances you want to power?
Hi I am trying to understand these inverters, when not using any power they will charge batteries and if you put load during the day they will pull directly from inverter instead of batteries? What if you pull 2kw load on 5kw array will 3kw still be used to charge batteries and 2kw pulling directly from inverter? Thanks for anyone who knows this xD
Yeah, you can set it up for solar first, then Utility, then Battery, "SUB" mode. And the battery is optional so what is super neat, is we can connect solar panels and grid power and power the load with some solar even if the solar is not enough like in the morning or evening but at least the solar helps. The battery is just there in case the grid goes down.
