Load Output Settings - Victron energy SmartSolar MPPT 150/45 Manual

By default, the solar charger uses its internal temperature for battery temperature compensated charging. An internal temperature
reading is taken in the morning and then again when the solar charger has been idle for at least one hour, for example when the
charger is not actively charging a battery or supplying a load.
When the solar charger is part of a VE.Smart network and receives a battery temperature reading from a Battery Sense or
a battery monitor with temperature sensor, the actual battery temperature will be used for temperature compensated charging
throughout the day.
Low temperature cut-off
This setting is used to prevent damage to a lithium battery by disabling charging at low temperatures.
The "Low temperature cut-off" feature is only active when the solar charger is part of a VE.Smart network and
is receiving a battery temperature reading from a Battery Sense or a battery monitor with temperature sensor.
The "low temperature cut-off" setting is by default disabled. When enabled, a low cut off temperature can be set. The default
temperature is 5°C, this is a suitable temperature setting for lithium iron phosphate (LFP) batteries. However, always check with
the lithium battery supplier to find out what this temperature should be set at.
The "low temperature cut-off" mechanism will stop battery charging when the battery temperature has dropped below the low
temperature cut-off setting. Battery charging will resume once the battery temperature has risen 0.5°C above the low temperature
cut-off setting.
Note that setting "low temperature cut-off" is not needed for Victron Lithium Smart batteries or for Victron Super Pack batteries
with serial number HQ2040 and above. This setting is only needed for lithim batteries that are unable to block charging when the
temperature drops too low.

5.2.2. Load output settings

The load output settings be used to drive the TX pin in the VE.Direct port, which can then be used to drive a BatteryProtect, a
relay or an other load-shedding device. For more information see chapter
