How MPPT of this Inverter

I got this inverter because my 3 year old inverter died. (I added 2 computer fans and got 6 extra months because it was overheating). Eventually fuses kept blowing and he died. The new inverter appears to be better designed for cooling as it has 2 fans on one end as opposed to the old inverter's 2 smaller fans on opposite ends resulting in fewer holes and less airflow. I kept 2 computer fans so I'm hoping this new fan will stay as cool as possible and last longer. I have a 24v solar system (I used a 24-12v converter for the fans) and it is connected directly to the batteries. Haven't seen it running in full sun yet, but I've noticed that the inverter's MPPT matches exactly (maybe -20%) what the charge controller is putting out, which I like as it doesn't drain the batteries as quickly. to the cutoff point I set on the relay that powers it. (shown in figure 2) This will still drain the batteries, but not as quickly, which saves the relay. (which also has a computer fan for cooling) The old one ran at full power until the battery voltage dropped. It's only the first day of installation, so I'll update whenever possible.
