Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

The Isc on 12v PWM starts to decline in the 13s and is a bit lower into the mid 14s then falls off a cliff around 15v. (see a panel's IV curve)
"It depends" whether you lose a bit of amps from that or from the battery being nearly full so it won't accept anymore and tapers the amps from that. Or both reasons for amps tapering can be happening. It depends on the charging rate, being the amps the panel can do wrt the "size" of the battery bank.
