Outback RE200's DEAD

Hello,

I have a AC coupled system, Radian8048A (48v) with 8 batteries connected in an IBR. We have never had a power outage in our area since installed. I've checked them periodically for SOC and they have always been fine.

This afternoon I noticed my Mate3 was off, went to check it out and the batteries were at 11V.

I have no idea how this happened, more bad luck. There was no data logging going on.

Thoughts on how to get these batteries charged back up?

Mike

How did you check the batteries?
SOC is an only an estimate of the charge level and if based off the FNDC can be wrong.

Unfortunately a multimeter will not be accurate but may give you a guide if you isolate the battery bank and allow it to "rest" for at least 12 hours.

Regards getting the batteries charged up, I hope someone else can provide you with some input as I am sure it has been mentioned in other topics. I can only recommend getting a suitable external charger or somehow getting the solar charge controller (FM80) to power up by getting more than 10V to its battery/output terminals then "the LCD should be on, and once solar is available it should start it normal wake-up."?
