My house is currently 240V. Can I use this inverter which is 120V?: https://sungoldpower.com/collection...erter-parallel-wifi-monitor?sscid=41k6_lksx1&
Yes as long as it is ok if no 240v items need to run.
I have no idea, but I do know that live in North America. LOL. I'm trying to figure out the best value inverter to cover all needs and allow maximum expansion potential. I would like to put more and more of my loan off grid, but keep access to the grid.Is your house 240VAC@50hz or 120/240VAC@60hz?
In other words do you live in North America or elsewhere?
If the Sol-Ark is out of your price range AFAIK that leaves MPP or Growatt.The Growatt SPF5000ES seems like it would be great, but I just saw a video from Jan. in which Will explained there are issue with grounding.
This one (https://watts247.com/product/lvx-6048-hybrid-solar-inverter-split-phase-120v-240v/) seems good too and can be paralleled up to 9 units (54kw). Sol-Ark may be the best, but the cost is prohibitive. Any opinions about any of these? Or do you have another one that you think is better?
I think that unit is a single phase, 240 volt, European model. Not worth the headache, IMHO.The Growatt SPF5000ES seems like it would be great, but I just saw a video from Jan. in which Will explained there are issue with grounding.
They ‘can’ but I wouldn’t do it. I’d buy the right US models and properly arrange them to run a subpanel that handles your needs safely without hoop jumping or high wire dancing. I can see why you would want to run a 240V well pump on solar but if you’re wanting to be running a water heater or electric range I personally would not want to spend the money to accomplish that.Can a transformer be used so that 240v items can be powered by a 120v inverter?
Or can a transformer only allow 120v items to be powered by a 240v inverter?
No, not in North America. You could step it up to 240v single phase, but anything here would take 240v split phase. The motors inside the equipment are wound differently. In some cases you could use two separate 120v inverters to make a "split phase" 240v, but you definitely need to check the spec sheets and make sure they can be linked.Can a transformer be used so that 240v items can be powered by a 120v inverter?
That could be done, but would more or less defeat the purpose of getting the 240v unit, because you still couldn't run your 240v items.Or can a transformer only allow 120v items to be powered by a 240v inverter?
Transformer can step up the voltage, step down the voltage, and/or create split-phase 240/120 service. However the size to power your home will be significant and the set up will be a costly addition. Transformer does not make power, just converts voltage.Can a transformer be used so that 240v items can be powered by a 120v inverter?

I think it should start the A/C fine. Run time will depend on battery capacity. I assume the running power is close to 3kWI live in northern California (CA). I just saw that Sol Ark now has a 15k system coming out in May-June. Maybe that's the way to go. Do you think that would be enough to run my 3.5 ton Mitsubishi VRF (variable refrigerant flow) central A/C for 2-3 hours per day?
