    I guess I'd be interested in an isolation transformer (which is not something I knew about before this discussion) feeding the inverter. There is lots of info about sourcing inverters out there, but less it seems about isolation transformers. Where does one source a 6000W isolation transformer...

    I think I found and appropriate isolating transformer. About the same price as the inverter! Oh well. 15 kVA 240 Volt to 120/240 Volt Single phase Isolation Transformer SC15C-K/Z3 Or a cheaper one with aluminum conductors: 15 kVA 240/480 Volt to 120/240 Volt Single phase Isolation Transformer...

    Thanks for that. When originally shopping for inverters, I also considered the MPP LV5048, which seems like it was two 2.5KW inverters mounted side by side in one case (no transformer?). Would something like that work in my setup, or would it have the same issue? Is the fact that the generator...

    I'm communicating with Franklin at Sigineer and he is also flummoxed. Our back and forth reveled one aspect I still don't get. I understand that since the input to the inverter, all the loads, and the generator L1 and L2 output are all in the same transfer box, the inverter can "see" and try to...

    I'll admit that most of this is over my head, but here is what I think is happening. Since the inverter input is connected to the same junction box as the generator and all loads, the inverter input can "see" the loads being drawn from other sources even though they are not connected to the...

    I have written to Sigineer to ask if transformerless inverter/chargers would encounter the same problem. For about the same money, I could stack two of these together: M3048NC I could then use the inverter I already have in a separate out building that is powered by its own generator.

    Just to follow up, I did end up installing two M3048NC and so far, so good. Loads in the house (which the inverters power) pull power from only their respective inverter. When the generator is running, the loads from the barn and shop are not affected by the inverters, and no unplanned balancing...

    Yes, the inverter is connected to the same junction box fed by the generator where the load from all other sources is also connected. This seems like it must be the case - but I didn't know it was possible for the inverter to "see" voltage draw from sources it is not connected to other than...
  • Post in thread: Documenting Purchase from Amy Wan of Shenzhen Luyuan Technology Co. LTD. Alibaba

    Hello @myles. I am in BC, Canada and ordered 16 cells from Amy about a month after you did. I am curious if the rest of your cells arrived and if and when the UPS tracking page ever populated with delivery dates. My cells are being delivered to Vancouver Island and I'm hoping they can avoid...

    Hello all. I live very remotely with no access to grid power. I use a diesel generator without any real battery storage systems. I am in the process of adding a 48v battery system to power my house in the evenings so I can turn the generator off. Eventually, I will add solar to the system to...

    My generator can put out 20KW, and I sometimes will be create large 120V loads on only L1 or L2 . If I'm understanding you correctly, the inverter could see a 10KW imbalance from the shop and/or barn and try to rectify it. But I would assume the transformer in the 6KW inverter would be overtaxed.
