I have the operation & intallation manual for the batteries, now, thanks to the internet and a lot of patience (11 MB!) Yes there's a correction factor in the appendix of the manual, but how do I turn that into a useful instruction to the C40? It came with a temp sensor, but how do I know that the right correction will be applied? I can't configure this factor. Maybe that's a question better asked of Trace/Xantrex.
What's really got me squeamish, and I should have explained in my original posting, is that the C40 has "bulk" charge and a "float" charge settings. As far as I can see in the battery manual, there is no "bulk" charge voltage specification. It doesn't mention bulk charging at all.
Should I set the "bulk" and "float" knobs to the same voltage, so as not to overcharge these cells? I've already discovered that equalization charging is clearly not recommended for sealed batteries.
+/- 10% on the SOC, eh? Then I'm somewhere between 80% and 100% hehe.
The loads currently are pretty light, but I'm on the verge of trying electric water heat in the horses' water troughs (approx 1200Watts). This is just within the inverter's limits and there may be some significant voltage drops in the wiring I have available. However, I want to go ahead when I have the rest of the system set up, and that will be soon. Maybe just from the "management" point of view, it's better to get the C40 in ASAP and then push on to heavy electrical loads.
Thanks, I needed to talk that out. I feel better now.
