10.3.5. DC input low pre-alarm
DC input low pre-alarm With this setting one can determine the level at which the Low batter pre-alarm indication starts. Note that
in fact the parameter which is changed is an offset voltage relative to the DC input low restart level which in its turn is relative to
the DC input low shut-down level. The result of this is that, when changing either one of DC input low restart and DC input low
shut-down, this "DC input low pre-alarm" level changes also!
10.3.6. Low SOC shut-down
If the Multi is set to have State of Charge enabled, you can use this feature to shut it down when it reaches the set level. This can
be useful on systems where battery voltage does not give a good indication of battery level.#
10.3.7. AES
Energy saving setting to conserve power if there is no significant load drawn from the inverter.
If the system has consumers with high inrush characteristics (such as microwave ovens and air-conditioning) deactivate AES to
prevent them from switching on too slowly and causing overload
10.3.8. PowerAssist
Use PowerAssist to prevent an external AC input circuit breaker to trip due to excessive load. If the load exceeds the AC input
current limit the Multi will start inverting in parallel with the external AC supply and will provide the extra current needed. Note:
When PowerAssist is enabled there is a minimum AC input current limit depending on the device type. Setting a lower limit than
this minimum will result in the minimum limit. Note that in a parallel system this limit is per device!
10.3.9. Assist current boost factor
This value is normally set to 2. This is a safe value because any small peak will be compensated by the inverter and the
excessive power will not overload the input circuit protection. Be very careful with this setting and change it only once you have
carefully considered the possible negative aspects of doing so!
