I've recently switch from a Bogart Engineering Trimetric + SC2030 to a SmartSolar 100/50 MPPT.
Aside from underwhelming bulk gains and inaccurate metering, I'm also having problems with the absorption termination.
The manual states this is done based on either a (fixed!) 2A current limit, or a very crude 4-option time calculation based on voltage at first light - whichever comes first.
The problem I am having is that auto time calculation is consistently off, always skipping to float prematurely, far before the 2A cutoff or battery recommended termination current. Consequently, this unit is consistently failing to achieve 100% SoC (accurately measured with the Trimetric monitor) .
Is there any way to remove the time limit from this unit entirely, so it holds absorb to 2A termination? Or better yet, an adjustable amp value? I've set the 'max absorption' to 6h but it seems to just ignore this setting, and I see no other parameters to tweak.
It's very disappointing - right now this unit is failing to achieve what the far cheaper PWM Bogart unit has been doing reliably for years.
