The issue:
Load output does not switch at the configured voltage in the "User defi. algorithm 1" settings. See attached screenshots. Looking at the trends graph, the "off <" voltage seems static at 11V + 120 seconds delay (?) and the "on >" seems static at 13V + 120 seconds delay.
I was hoping to have the load switch off rather sooner than 11V and later than 13V. What am I missing here, why doesn't it work as expected?
The setup:
- SmartSolar MPPT 75/10
- 6Ah LiFePO4
- Static-current load @ 1A
- 30W solar panel
What I've tried (in this order):
- Searched other issues on this forum; then
- have the latest firmware installed (v1.63);
- reset the device to factory defaults;
- disconnected the SmarSolar from everything for a couple of minutes, and reconnect loads first, then battery, and solar last; and
- waited at least 2 mintues before making my conclusions about the load output's behavior.
Good to know:
- the voltage of the battery measured at it's terminals differs from the app by 0.0 - 0.3V;
- there is no jumper on the VE.Direct port; and
- the load output configuration for "always on" and "always off" work perfectly fine, so this doesn't seem to be a hardware issue.
- Streetlight function is disabled.
- MPPT settings save file
