Hi everyone!
I'm new here, and I have a question:
I bought this: https://www.cotek.com.tw/sr1000t-1000w from ebay, and it's very close to what I wanted.
It has 240v AC and 48V DC inputs.
You can configure it so that DC is primary, and AC is secondary, and you can configure under voltage and over voltage limits, which is nice, but the highest voltage you can set it to swap from using DC back to using AC is 48V, which isn't good for my LiFePO4 batteries.
I would prefer it to swap over at 50 or 51V so I don't drain them too far, but I cannot set it this high.
This means I have to manually swap over with the physical switch on the front, or try and get a serial cable that works so I can control it from a computer.
Neither is ideal because I don't want my computer to be polling the inverter all the time, with the risk that it won't swap over at the right time (dodgy coding on my part, system crashes, or having to have the computer connected/on all the time etc).
Can anyone recommend a similar device where you can set a more sensible voltage or a LFP system?
I contacted the manufacturer, who at least replied, but said there is nothing I can do to change the limits.
I know there are ATS that are similar, but most seem to be 2 x AC inputs, so I still need a separate inverter, which would be annoying.
Thanks!
