Hello Wrenches,<br><br>
An MX 60 boiled a 24 volt bank of 4 Trojan L-16 batteries last summer.
The batteries all checked out to be in good shape. It is not totally
clear that the CC was not set to auto equalize, but the EQ voltage was
only set at 31.0 V. <br><br>
The battery bank has been replaced by 8 Full River L-16 AGM batteries.
The parameters have all been reset for AGM with EQ disabled. The
homeowners are concerned that the charge control may not work, and damage
their new battery bank. <br><br>
If there is a problem with the CC, it is very intermittent. Has anyone
ever seen an intermittent MX 60? <br><br>
Outback tech support says if we send it in they will update the firmware
for $90, and do a 24 hour bench test. It appears that the firmware update
will not do anything useful for this off grid system. There are no new
boards available for this unit. I'm not sure if the bench test will show
up an intermittent problem. <br><br>
Has anyone had this situation before? Would it be better to:
<ul>
<li>Replace the CC
</li><li>Send the CC to Outback
</li><li>Do nothing
</li></ul>Thank you,<br><br>
Drake <br><br>
