Aux 2 Waste Not Temp Compensated?
« on: November 12, 2017, 09:29:44 PM »

I've been using the Local App to monitor a new system that has an opportunity load. As the sun goes down, I can see that in float, AUX2 is pulsing high well below the target compensated voltage(28.5v) minus the offset(-0.9). It appears to be offsetting from the set voltage(27v). I've seen the AUX2 light come on all the way down to 26.5v, at that point a safety contactor opens cutting off the opportunity load.

While researching how to set up an opportunity load with Waste Not Hi, I came across several posts that indicated that Waste Not was temperature compensated. Possibly that changed in later firmware? Can anyone confirm that it is, or isn't?

Thanks

Yes, it does follow the temperature of the battery.

Maybe unplug the temp sensor and try ?

I'll try that the next time I get out there. But I don't think it's a temp sensor issue, because it's correctly compensating the charge voltages.
