Re: Is anyone using an arc welder with an offgrid system

Well, 220A on 35mm2 cable means 6.3A/mm2, not so bad, but of course in 24V, if you have some distance, it can still have drop in voltage. Of course the bigger the better. Do you have a mechanical power ON/OFF switch on the inverter ? So it can easily and remotely be controlled by paralleling the swi...

Re: Is anyone using an arc welder with an offgrid system

I'm on 24V, 8x160Ah WINSTON LiFeYPO4 cells with Electrodacus SBMS http://electrodacus.com/ For best temperature, I have the battery in the house, and to get as short cable as possible to the inverter, I'll probably install the inverter also in the house. But I should only need the inverter when work...

Re: Is anyone using an arc welder with an offgrid system

Hi Dave. No I didn't try google lens. I didn't even know about ! I tried to figure out how to use it but didn't yet understand if I can use it from my laptop or if I need an Android phone to use it. It's very unclear ! I have an Iphone but need IOS11 I think and I'm on version 8. Then I must upgrade...

Re: Is anyone using an arc welder with an offgrid system

Hi Dave What kind of BMS do you have for your Lithium cells ? Did you try some inductive load on it ? Like a compressor or high pressure cleaner, something with an induction motor as they seem to be the worst to start ? I got in touch with a Chinese supplier, the price seem good, but shipping to Fra...

Re: Is anyone using an arc welder with an offgrid system

I had a large Victron on my barge in France for 8yrs and so far this thing is performing .... My next test of this thing is going to be charging my electric car at around 4,800-5,000VA. Regds, Dave Dave, where are you ? I thought you were from Australia but here you're talking about France. I'm fro...

Re: Is anyone using an arc welder with an offgrid system

Well, thank you very much for the photos !

It looks a big transformer indeed !

How much did you pay ?
How much for shipping ?

Re: Is anyone using an arc welder with an offgrid system

For me, LF inverter are the type to chose when you have big inductive loads like motor. In that case you mostly need high starting capability, (high surge current) for short time. Once the device has started, the load goes down back in the inverter's spec. Plus most of the power tool will run for so...

Re: Is anyone using an arc welder with an offgrid system

You should have ask if it has toroid transformer or EI iron core transformer because it can make a big difference in power ability/weight, toroid are supposed being much more better in the ratio power/weight. Plus one of the problem with all inverter but worst with LF inverter is the no load consump...

Re: Is anyone using an arc welder with an offgrid system

One solution may be to use a smaller inverter with an auto switch through when a stable 240vac supply is sensed on the mains input. Do you mean "when a stable load is sensed on the line" ? That way all the low power devices can run on the smaller more efficient inverter and the bigger draw items po...

Do grid tie inverter have "NO LOAD CONSUMPTION"

My question might be a little stupid, but learning about inverters, I discovered that off grid inverter would have a quite high "NO LOAD CONSUMPTION". Some have 25W, 50W when on standby mode, and some up to 192W (PV3000-MPK from MUST-SOLAR° So I wonder if grid tie inverter would have such kind of co...

Re: Is anyone using an arc welder with an offgrid system

Hello Coulomb. Being a specialist (if not THE specialist) of the MPP-SOLAR inverters, for my needs, and from your point of view, would you go for the HF MPP-SOLAR PIP-4024 or the MUST-POWER PV3000MPK 24V/6kVA. The prices seems to be almost the same. About your previous post, I think yes, the solutio...

Way to start and stop an inverter

Hi everyone.

I've videos were people start or stop load already plugged in inverter from the inverter"s switch interrupter.

Is that a way to go with no bad side effect ?

Or should be the inverter started first, then plug the load, use it, unplug the load and last switch OFF the inverter ?

Re: Is anyone using an arc welder with an offgrid system

As I am in contact with both MPP SOLAR and MUST SOLAR to make the choice about my inverter; again MPP SOLAR are very confusing not directly and accurately answering my question. I asked them if the PIP-4024 could start the same inductive load as the PIP-5048 (considering what said offgridQLD) and th...

Re: Is anyone using an arc welder with an offgrid system

Yeah, got it back to front, PIP4024MSP. I thought the P stood for parallel capable, not a different power factor. They are sold as 4kW/5kva, 60 amp max 240vac charging, 80 amps MPPT controller with a max open circuit of 145vdc and Vmp range of 60vdc to 115vdc. We also use their MPPT solar charge co...

One of the off grid house setups we did powers a stick welder from a 2440 MPP solar inverter supported by 600Ah @ 24v of Winston lithium cells.. . .. T1 Terry 2440 or 4024 ?

Re: Is anyone using an arc welder with an offgrid system

The biggest point from now is that I've no feedback from the LF inverter from MUST SOLAR. The Must brand causes a few of us to bristle, because they were the original illegal cloners of Voltronic Power / MPPSolar products. But their other products may be fine. Would be any feedback, review, fix or ...

Re: Is anyone using an arc welder with an offgrid system

Hi everyone. And thanks so much for these very helpful response. I think you'd be better off with an inverter with an old style big low frequency iron transformer in it, like a Victron. They have a better surge rating, and it seems to me that several of your intended loads will have significant inru...

Is anyone using an arc welder with an offgrid system

Hi to all. Is anyone using an arc welder with an offgrid system ? I have a 24V Solar panel/battery/regulator and am currently trying to choose an inverter. (battery is 8S 160Ah LipoFe4 WINTSON cells capable of 1600A for 5s peak at most, 480A for 15min, 80A continuous, so, 38kW for 5s, 11kW for 15min...
