Looks like a flat battery. Solar not enough to cover use.
Well there we go, two different interpretations of what is displayed on the screen, however, if it is showing 12.6v, then I am not of the opinion that the battery us goosed.From left to right, is telling you that your leisure battery voltage is 12.6v, (almost fully charged), as you appear to be using 3% of it's capacity, and that your solar input is only 0.1 Amps. However, the last graph is showing an even balance, ie, neither a drain nor a charge.
That's just my honest opinion on what I see from the screen.
How can that be when the battery voltage is showing full, ie, 12.6v/12.7v? If that were the case, the voltage reading would be nearer 11.0v.It’s showing you only have 3% capacity left in your battery. In other words you’re about to run out.
Going by the capacity it is empty. But as you all say the voltage is good. Go figure.Well there we go, two different interpretations of what is displayed on the screen, however, if it is showing 12.6v, then I am not of the opinion that the battery us goosed.
I'm no luddite, but does anyone really need the interior of their motorhome to look like something out of the starship Enterprise?.....I respect those of you with the intelligence to interpret these technologies, but really I have managed for decades without all this "hi tech" stuff..
Yes I think that you have cracked it. The Ah setting had not been correctly calibrated. A good plan to be sure you are fully charged on EHU and reset to 100%. I set mine (a different system but does show Ah) to 2/3of the total lead acid capacity so I only ever go down to that level before being alerted. In reality with a good solar system and a B2B I rarely even get below 50%. My batteries are now 8 years old. I keep hoping they will fail so I have an excuse to buy lithium! If you have AGM I believe you can safely discharge them lower.Morning all
Thanks very much for all your replies. Update: read the Sargent manual and it states AH reading is approx capacity of battery= so 3% at that time. Does say more important reading is the V.
I checked the AH setting in the unit and it was on 0%. Although not sure why or if that was a true reading of the current battery status (x2 95Ah = 190 Ahrs??) I changed the setting to 60% as an estimate of its current charged status as we had been off grid for 4 days. Once done the AH display reflected new inputted measure ie 60%. Settled down for the rest of the day/night, usual tv, lights, water…. without crashing. Checked this morning and the AH is at 50%. So at my reckoning that is a 10% loss of capacity. As the initial reading said I had 3%, that’s a difference of 7% so would indicate AH reading was incorrect, set wrong for some unknown reason? Volts now12.5!
Plan: moving to ehu site today. Charge every thing up for 2-3 days. Unplug, note all readings, set AH on unit settings to 100%. See how get on from there as will be heading to Lincoln SG for 4 days shortly, test out again off grid!
Apologies if I have rattled on a bit, I do like to tell a good story.
If in the meantime anyone has any further advice, it would be gratefully received. Thanks again
