Slowly Understanding the Battery Monitor

I checked the battery monitor about an hour ago and I was still 20AH away from a full charge and only putting in 4A. Now, it’s flashing full!!!

I think I know what is going on.

The solar monitor gives me a reading at a given moment. I might be putting in 7A for a few minutes, but then the clouds come out and I start putting in 4A. I could end up averaging only 1A coming in for that hour despite that 7A reading at the beginning.

I think the battery monitor is giving me delayed information after the fact. That is, every so often, it tallies up what really came into the bank and then adjusts the amp hour total up or down. The computer is certainly sophisticated enough to do this.

Moreover, I woke up at about 24AH down and have been charging for 8 hours. The AH total has barely budged all day, until now, even though I was supposedly putting in about 3A all day. 3×8=24.

I wish there was a Xantrex LinkPro for dummies book. The information that comes with the monitor isn’t very helpful.

A Homey Day

Today was really low key. It’s a chilly and windy out there, so I’ve stayed in. An invasion force of pterodactyl-like pelicans landed this morning and have been providing Neelix and me with entertainment all day.

Caroline and her husband came by in the afternoon to tour the rig. Her husband gave me his thoughts on how and where I could add a giant monitor to my office setup. The number one thing keeping me from doing so is that I want to run the monitor off DC, not AC, so that I don’t have to turn on the inverter. He said that it’s doable so I’m going to do a bit more research on that.

Caroline had a nice present for me, a cross-stitch project that she’ll never get to, so I’ve already started on that and will continue tonight with a movie. I found a DVD with eight surprisingly good movies on it for just $5 at Walmart and have been watching one a night. It’ll be nice to have something to keep my hands busy in the evenings now.

Two Good Electrical Days In a Row

Today is another day with more sun than expected. It’s chilly, but I’m not complaining!

I’m going to have the computer on charge all day since I’m in major backup mode. My MacBook Pro keeps crashing, so complete hard drive failure is imminent. I just need to decide on a new drive and order it; the choices are a little overwhelming. I want to make sure I have several recent Time Machine backups and two different bootable backups. It’s likely way more than I need, but with the current drive being only good for the dump, I want all the chances I can get to be up and running perfectly about four hours from the new drive making it here.

Power right now is at 88% and holding. I’m actually getting 7 to 8A in, so I’m breaking even. The more the batteries are depleted, the more efficiently the alternator charges them, so I’ll wait till about 4PM and then run the engine for a bit to make sure I’m at at least 90% capacity tonight and then I’ll aim for 100% tomorrow.

In other news, R and S from Colorado are back, so a beach party is imminent!
