FAQs about Solar container battery cabinet voltage is lower than how many V the battery has a problem

Should lithium batteries be charged at a low voltage?

If lithium batteries have been deeply discharged they should be charged at a very low rate until they reach their minimum voltage above which they can accept the usualy high currents. So this sounds like a protection feature to me to prevent damage. but your batteries should never be seeing a low voltage disconnect event!

What if a boost voltage is less than 13.5v?

If the voltage doesn't exceed 13.5v that'd be a bit weird and counterintuitive to having a boost voltage of 14.4. Think of it like if the battery is below 14.4v the controller will throw as much wattage as possible at the battery.

What if my Pos battery is too low?

Bought 3 Rover Elites and that POS goes into a "overdischarge protection" mode if the battery gets too low, but when the panels come back up again, it won't start to charge again. Panels meter at 70V input and that controller won't come out of it's sulk and do it's job.

How many Watts Does a controller float if a battery reaches 14.4V?

Once the battery reaches 14.4v the controller “equalize/float” and will only give the battery as many watts as it takes to maintain that 14.4v (usually for a set time,2hr is standard). I believe ampere time balance voltage is 14.2-14.6v meaning if the battery never gets there it'll never have time to do any balancing.
