S550 new and not lasting
Hi all. I am new to the forum.
I live off grid with no grid ties.
I have a Schneider conext SW 48v inverter and an Outback 60 controller with 9 Canadian solar 330 watt 24 v Panels. They are hooked up in series of 3’s. I’ve bought new batteries last year in the fall - 8x Rolls Surrette S6 L16 HC 6V (formerly known as S550) 445 ah.
Over that winter they were excellent. Go to bed with 50.9 volts and wake up with 49.8 volts. All was good until one day in the spring I added distilled water as per schedules maintenance and immediately after turning system back on the overnight voltage dropped to about 48.8 at bedtime and 45.7 in the morning. I think that sounds crazy because that shouldn’t make any difference and could just be coincidence but it is fall again and I’ve had to run my generator several times even during the summer when I normally never do to daily now that the sun is less.
I’ve never equalized the batteries and am not sure how to. Can someone please help. Thanx
