<p dir="ltr">I would stop there and see if it is corrected. I have seen high SG when there is little or no boil offand water is not added, if someone has added acid the SG is not usable. You can use the entire system as it is a load tester turn off the pv, gen set and the wind put a 2 k load (ac) on the system and keep in on for some time now check the voltage at each battery this can show a poor or failing battery without the use of a carbon pyle or resistive load dump. I have done this with my off grid system and it works well.<br>

He had a bank of 4 year old Interstate L16HCL batteries, 2 strings of 8, 48V system, 840Ahr. We went through the batteries and got specific gravity on all of the cells post-equalization. I was a bit surprised to see some very high numbers ie over 1.32 for the specific gravities (higher than my refractometer goes). The specific gravities were all over the place, but I haven't seen numbers this high. I don't have a great explanation. He has a stacked 3648 VFX Outback system, and the set-points were 58.8V Absorb for 2 hours, and 62V Equalize for 2 hours. He has a decent amount of solar (about 3400W) and a 1000W wind generator.</div>
<div><br></div><div>Any ideas why the specific gravity is so high on some cells? Also, is there anything wrong with having SG this high, post-equalization? For this very standard battery, what settings do you go with (Bulk, Absorb, Float, Eq, and times for Abs and Equalization).</div>
