The available operation modes are:
• BatteryLife (default setting):
This algorithm is self-adapting and aims to maximise the battery's lifespan. For a detailed explanation of its functionality, please
refer to the
BatteryLife [7]
chapter for a description of its functionality.
• Conventional algorithm 1:
12V system: OFF when Vbatt < 11.1V, ON when Vbatt > 13.1V.
24V system: OFF when Vbatt < 22.2V, ON when Vbatt > 26.2V.
48V system: OFF when Vbatt < 44.4V, ON when Vbatt > 52.4V.
• Conventional algorithm 2:
12V system: OFF when Vbatt < 11.8V, ON when Vbatt > 14.0V.
24V system: OFF when Vbatt < 23.6V, ON when Vbatt > 28.0V.
48V system: OFF when Vbatt < 47.4V, ON when Vbatt > 56.0V.
• Always off:
The load output is always OFF.
• Always on:
The load output is always ON.
• User defined algorithm 1:
OFF when Vbatt < Vlow.
ON when Vbatt > Vhigh.
• User defined algorithm 2:
OFF when Vbatt < Vlow or Vbatt > Vhigh.
ON when Vbatt is between Vlow and Vhigh.
The "always off" and the "always on" modes will respond immediately. The other modes have a 2-minute delay before the load
output changes. This is so that the solar charger does not respond too quickly when, for example, an inrush current briefly lowers
the battery voltage below the threshold.
The load output settings also control the
deeply drained. The streetlight settings are overridden should the battery voltage falls below the load disconnect voltage. When
the battery voltage increases to the load reconnect voltage, the streetlight function will resume.
5.2.3. Programmable relay settings
The programmable relay can be configured to a variety of relay modes. Each mode will cause the relay to switch under different
conditions. Some of these conditions are pre-determined and some are customizable. In addition to the "relay mode" a relay
minimum closed time can be set.
