Taking another step in my solar experience.

[Ikkarus]

Hello,

I am new here and new to really getting into solar systems. I have played around with small solar systems and solar generators, and now I am making another step. I have a shop that I can't get power to, and I need to run a compressor and a welder in that shop. So I am looking to solar to solve the problem. I was pulled in by Will's video on the Lowest Price DIY Off-grid Solar System for 2025. So I am looking at work with those components.

I am thinking about making this a mobile system so I can disconnect it from the back shop and use it instead of my generator if we lose power.

A little nervous about the Yixiangpower battery, but I am also trying to do this as cheaply as possible.

What size compressor and welder?
Do you have any idea what the inrush current is on the compressor?

I would suggest one or two Schneider xw pros, on final clearance after decades of production of the xw platform.

Conext XW Pro 6.8kW 120/240 Volt Inverter 48V Charger

Note: Please look at our 865-6848-21 Schneider kits, you will find a 10-20% discounted system with these kits. NAZ-Schneider-XW-Pro-007 NAZ-Schneider-XW-Pro-008

They have huge surge capabilities beyond their 6.8kW rating, can deliver 12kW for 60 seconds. For welders and compressors its perfect.

Need one of these to configure a pair in master/slave, and monitor:

Schneider Electric InsightHome Energy Management device for smaller or residential systems

This is a poor suggestion for a beginner, the Schneider equipment really requires a trained professional to install.

Yes, looking at a single Sungold's price you could have a full one minute of 24 KW surge for $ 2900 using two XW's and an Insight home and PDP.
Would need two of the batteries and would need to source MPPT's separately if charging the batteries by solar instead of an inverter.

Or, reading your post do you have Grid AC available at the other location? If so maybe a two cart system with one inverter and one battery each then roll them in and connect the 120/240 outputs.

My nephew is working on a cart set up for a single XW pro, an eco-worthy 14.3 KWH battery, 500 volt 6000 watt MPPT and a mini PDP. Depending on what air compressor and welder you have a single XW may be enough Inverter.

I was watching an XW PRO video made by Schneider themselves and the designer/engineer said he knew of cases of a single XW pro running at over 9000 watts was able to start an additional surge motor load of over 60 amps with no shut down.

Quatro is right about the install and programming being more involved the XW pro operators manual is a thick book for sure, but several members have wired and programmed these Schneiders for over a decade already and this forum is a great source of help.

I have XW pros and ancillaries, but am currently running on an EG4 18k PV and it does a great job, like you in a grid down situation my air compressor requires to much surge current for the single HF Inverter to start it. I bought and plan to use the XW Pros for the high surge motor load buildings

Back to the basics like above we need the Model of welder and air compressor before any definitive concrete advice

Actually a single xw pro can simply be connected to a 48V battery and you are off to the races. No Insight needed.

David Poz ran his home of one like that for a couple weeks:

Interesting specs on the overload time. XW Pros can surge to 12K+ for a full minute and even higher for short surges but looking closer at the "20KW " surge spec on the SunGold: the same ~12K+ load would cause a shutdown in 5 seconds.

Actually there is wiggle room in that spec and it is possible that an 11.5 KW load could shut down the Sungold in 5 seconds.

XW is solid value for the price at this point

But OP said solar , I would sort of agree if they actually meant backup battery only.

You would need to add battery busbar to accommodate and pick a separate SCC

With a hybrid there’s fewer ways to fall off the wagon as a novice from being overwhelmed. IMO novices need to accept a factor of inefficient $$$ spending to compensate for what they don’t know. Which means probably buying a big HF AIO to be able to run shop loads

Will has a lot of HF inverter + “shop load” test videos. Referring to running his lift tests

Back when I was running the OEM version of the inverter the OP is asking about I had no issues starting my air compressor.

Need to know what size of compressor the OP is running.
Also, what's the surge rating for a single BMS in that yiaxiang pack?

Is the lift really a challenging load?

 

[455dan]

They are generally between 1 and 2 HP hydraulic pumps. My 10K bendpak is a pretty easy load for the Inverter.

The air compressor not so much although once the wheels are off the ground the pump does have an immediate load which means also an immediate high motor surge draw as well.

 

[Ikkarus]

for both the compressor and the welder, I can run them off my generator, which is just a 13,000 Watt Tri tri-fuel portable Generator from duromax.

The compressor is a 110 compressor, and I run the welder right now on 110 in the back shop. I am usually not pushing it back there; rarely anything thick.

In the future, I would like to run both off of 220, but not sure if I should go right to that or take smaller steps. I have to admit 220 scares me a little.

I am bad at maintenance, and one of the reasons I set the generator up like this is so it would force me to run the generator, that way an emergency doesn't happen, and I am stuck with a generator that isn't working. I have never run it off of gas, just LP and natural gas.

I didn't explain everything. The back shop has no grid power, just power from this generator. This same generator is what I use on my house if we have a prolonged power outage. It will run the 13000 watt generator (on natural gas, so more like 9000 I think). I have run our HVAC, Fridge, Gas stove, two fans at night, network equipment, and charge devices during the last long poweroutage. I am using small portable solar generators for the network equipment and freezer in the garage. I keep those devices connected to AC, until we have an outage, and then I move those over to solar.


The welder is an Eastwood 200 Amp Elite MP200i Multi Process Welder
The compressor is an old 110 Harbor Freight cheapy back when they had central pneumatic

The idea of a novice needs to accept a factor of ineffiecient $$$ spending to compensate for what we don't know makes sense to me. That being said, there is still a ceiling, I guess it would be better to say I don't want to spend more than I have to at my knowledge level.

I am good with paying more for something that will make me more successful and make learning easier, as long as I am not wasting money I didn't need to spend. So if my knowledge level (which is low) could do this for 200 dollars (I know that is a silly number) I don't want to pay 1000.00 to find out someone with my knowledge should have been able to do it for 200.00.

I am just trying to head off as many mistakes as possible.

 

[42OhmsPA]

I'll think you'll be just fine running them with the AIO you're considering, other options would work too.
I would put the compressor and welder on opposite legs. If you're running the welder on max off 240VAC you'll be around 85% output on the AIO, I don't think this would happen very often.
My biggest concern would be a single battery is undersized if you're running at max output for extended periods.

So I chickened out, and I am going to go with the double Pecron 3600 setup, take the back shop 100% solar. Move the generator to a shed near the generator plug, and abandon the mobile part of it.

The final cost of the double PECRON setup was about $2,400. Now, I am working on panels that will fit best. I didn't want to use the PECON panels because they are mobile panels, and I plan to mount them on the roof.

I am checking with the city to see if I can put panels on the shop without permits if the shop is not hooked to the grid.
