What I do not like is the rated Load Current max of 20 amp. Also Max PV input power. I have 1000 w, this spec states = 24 V system and not 12.


No 40a mppt controller will handle 1000w of 12v without clipping the excess amperage, thus defeating the whole purpose of mppt.

I'm afraid you misunderstood the specs. 40 amp output at even 14v is only 560 watts. No way it will throughput 1000 watts.
