maximum wattage load with quatro 3000

I have a quatro 3000 24v and doesn't like to run to 2000 watts for very long, I know its supposed to handle 2400 continuously, so if its not the quatro what else might be not coping with the load?

Wiring and heat issues? Battery not able to cope with high amp drain. At 24v you need a bank that can sustain 125A

If it cuts off there should be an alarm LED blinking/on.
Overload, over temperature or low battery.

The rating for 2400W continuously is at 25°C.

Hi Mathias the Quattro reports low battery, but I have a new AGM battery bank of around 900 ah so would be surprised if that was limiting the power output, so the rating of 2400 @ 25c would be lower at a lower temperature Ie winter/summer, morning/afternoon?

If the size of the battery is not an issue, then it will be cable size or resistance causing a voltage drop. Bank configuration as well causing bad current sharing? Unless ESS is installed and C rating is too conservative in the assistant making the system shutdown early.

Hi Alexandra cable sizes are fairly short and over rated so can’t imagine that would be a problem and I’m sure the bank config is good, though I might try checking the terminals are tight, sorry but i Have no idea what ESS is, could you explain please.
