Solar MPPT and lithium batteries
I switched my AGM batteries to lithium's. I can't get a definitive answer on MPPT charge parameters, except to "user define" which I have done. My question is: since MPPT chargers rely on voltage drop to start the charging process, and lithium batteries maintain a consistent voltage until depleted, how will the controller know when to charge? The "user defined" parameter settings seem like a work around, but spending a week and watching the voltage stay the same, but capacity drop with minimal amperage charging from the solar panels, I wonder how long before they are depleted? Is there a solar charger that uses capacity drop to start the charging process?2.1KViews0likes9Comments
