As you can see by the chart above, we hit float for over three hours yesterday! That's really exciting to me. We haven't seen float since last fall. The minimum battery voltage throughout the winter was always so low that float was cancelled the following day. In spite of that causing some very extended absorption times, the Surrette batteries are still only sipping distilled water. I don't have to add very much at all to keep them topped up.
You can also see that we equalized a few days ago - that's another exciting aspect of the longer, sunnier, warmer days - we are starting to have the ability to equalize again. This should help with the long term health of the batteries. It also means that when it DOES equalize, the equalization voltage doesn't go over the 33.6V that causes our inverter to shut off. It can be a little bit of an annoyance to lose internet access in midwinter for a few hours while the batteries top up.
This is just another in a long line of blessings I count. (Donna and Kenny being my daily number one choice!)
