Off-the-Grid with Outback not so good

[GrandmaOffGrid]

Hi. I have been off-the-grid for 2.5 years and things have never been quite right. Has really been deteriorating since Nov 2021. Looking for consultant who can help problem-solve. Suspecting Outback. Live northeast of San Diego.

Have you contacted Outback Power regarding the firmware issue to get that resolved? That is where I would begin in order eliminate that issue. It looks like you have a Frankenpack of BigBattery Lithium and Pb battery chemistries which could be why they are not holding the charge. More data is needed.

I agree. I suspect the firmware too. I think I may have found someone who can help. I may be back with more questions if this person cannot assist. Thank you.
