[RE-wrenches] Outback settings adjustment so batteries consume less of PV output

[Tuss, Lones]

Hi Chris
Thank you for taking my phone call.
In looking at the optics site I see your array peeking up to 4230 watts at times. The Inverter being used is a GS4048A so it is selling up to its limits. The good news is with an oversized array your yearly harvest will be increased as you have more solar panels being able to contribute during low sunlight hours. However during peak solar events the inverter becomes the limiting factor as there is more harvest available than the inverter can sell.
I hope this helps.
Take Care All

I have not been able to find a way to set my customers battery charging parameters so that the AGM batteries do not consume less of the pv output to maintain charge.  Here is an Optics view of the situation with a small image embedded. (If you can answer, please remove image per Mr. Welch's request.

I have the absorb voltage at 54.3 for one hour, the float voltageat 54, the equalize at 56 (disabled for this battery type).

It seems like this is a lot of energy being used by the batteries, but I am hoping that some one with more experience in these settings can weigh in on any changes I should make, or if this is just how it is.  Thank you, Chris
