No time to get the Trimetric before my trip but things are looking better. Today's observations ...
- RV20 controller showed 13.0v after sitting for weeks in storage with just solar and nothing on during that time. It was early evening, no clouds all day, and cool temps in 60's so should have been as good as it gets.
- I got a copy of the RV20 user manual and it recommends doing a "Battery Fuse Removal Test". Pulled this fuse and it went from 13.0v to 13.3v. This is good sign controller is ok and connected to battery properly.
- Started generator and got 13.6v. This is better than got last trip. Checked with DMM directly at battery bank and got 13.45v
- Plugged in my new IQ4 module to the Iota DLS and fired generator again and now getting 14.7v on RV20 ..... YES!!!! .... DMM at battery shows 14.54
- Let the generator run and after about two hours noticed it dropped down to 14.1v .... Seems perfect, was in bulk charged and now switched to absorption. Will let it charge for several more hours until see it go down into low 13v's to know it switched to float.
It is dropping into the 30's tonight so will see how the batteries now do as heater will run a lot tonight.
Will tweak RV20 for a little higher solar voltage tomorrow.
If anyone wants the Shell Solar RV20 user manual pm me email address and I can send.
