Fitted 165w solar array via Votronic MPP 250 controller with associated LCD Solar Computer display a few days ago and all worked well considering available light.
Yesterday however, in full (low) sun, I noticed the red 'V' symbol flashing on the MP 20-T van control panel. This would normally indicate a low Hab Batt voltage yet output from the MPP indicated 12.7v to H.B.
I disconnected the S.P. and the warning stopped.
2 x 90a/h AGM H.B.s
Resting voltage is 12.7v after 20 hrs.
S.P. max output was 2a
MPP controller set to Lead Acid / AGM1 (main charge voltage 14.4v ! )
EBL 101 does not have AGM setting and is set to Gel as per original fitting.
I don't feel I should ignore the warning and the only solution I can think of is to change the MPP setting to Gel thus producing something similar to the EBL.
Has anyone else encountered this problem ?
Any assistance, ideas or words of wisdom would be very much appreciated.
Many thanks
