Thank you for your kind words. From the beginning, I treated the project very seriously because I put a lot of effort, money, my time and your commitment into it.
There's something about it that makes me want more, do you have that too? Now the idea of building another inverter - a reserve one, or a "summer" inverter to power the air conditioning - is slowly blooming in my head. This time I will approach the topic more relaxedly.
These small casings are described, but the camera operator failed to focus
There is also a third housing, hidden under the battery BMS display. There is a BMS module start-up switch on it, and an additional fuse box set for 12V inside.
The radio noise is still there. I'm usually on the radio in the evenings, then I disconnect the PV thong by the breaker. Ferrite rings on the cables do not solve the problem. I would like to use full-fledged EMI filters on the MPPT inputs, I will look for new ones or build my own.
Now what I'm going to say will sound strange, because it contradicts what I said earlier. At first I assumed they could be there together because it's cold there in the winter, so I hoped the others would warm it up a bit. Lifepo4 does not like to be charged at low temperatures.
Now that it's all in place, I can take measurements and make a final decision.
