I'm just saying it would be better to run parallel/mppt, if and when the panels and controller are hot. Less bucking means higher efficiency, lower heat generation, and thus better overall performance.
Same as when not hot. 1% efficiency difference between 33v and 66v (12v system), same power. I'm sure the owner's manual graph ignores voltage drop ๐

Are you saying you have some loads tied directly to the controller's 'load' terminals?

smk, I hope the Tracer qualifies as a 'good' controller ๐ If so, a great deal at $150 (incl remote monitor)

Good point regarding using the solar to power loads. I don't usually think in terms of powering loads, just charging. Of course, I do realize solar is running loads all the time, in essence... just thru the bank first.
Yes, I'll try contacting ep solar, and see what they have to say. Maybe as long as I add a fan or two, it'll handle being maxed out.
The loads don't run through the bank first. The power out of the controller is there with no resistance unlike there is when the bank discharges. The only reason any power comes out of the bank is because the demand is higher than the output of the controller. Also I have started a system up, started a inverter running a light and then removed the battery. as long as the sun shown the light stayed lit.
That's why we have a A/C that pulls 450w, one of the burners on the cook top pulls 475w, a heater that pulls 400w and so on. The batteries are there for the short term big loads, over night and bad weather. Most days they are rarely out of float.

I would call Tracer and ask. The Eco-w doesn't say it will or wont clip amps but I have seen someone running a pair of 150ws in series and pushed it past its 20a limit. It stopped at 20.1a. It will also clip amps if it gets hot too.
I believe someone here uses a Rogue 30a MPPT controller with 490w, maybe they could chime in on how often they see it clipping amps.
I would over panel the MS in a heartbeat if I had the room. It would be great for lower light situations and let me do more earlier. It would also let me use higher watt items during the peak hours. It would be nice to see the full 60a the controller is capable of.
