Hi,
I have a Victron Smart Solar MPPT 100/20-48 and I recently replaced my AGM battery bank with a LiFePO4 battery that is rated for charging down to -15°C at 0,2C. I was going to set the Smart Solar to disable charging below -10° to be on the safe side, but it won't accept a value below 0°.
Is this something you're planning to change with a future firmware update?
Another feature request on the same subject, it would be nice if the Smart Solar could charge at full power above a set temperature, and a lower charge rate at lower temperatures.
