Tycon Power TP-BC24-300 - Manual (Page 4)

If you connect a solar panel or wind turbine to the BATTERY terminal at the same
time, if AC failed, when the battery voltage lower than 21.5V, the LOAD output will
turn off, but if the output voltage of the solar panel or wind turbine is higher than the
battery voltage, the battery will be charged by the solar panel or wind turbine, when
the battery voltage is back to 25.2V, the LOAD output will recover automatically.
The maximum load of the PS is around 300W, which means 8A maximum DC output
on LOAD and 12A maximum charge current on BATTERY. If the load draws 8A
output, then the charge current will be limited to around 4.5A, if there is no load, then
charge current may be up to 12A maximum.
The output voltage on LOAD terminal is regulated at 24V±0.5V, with over voltage
protection, over current protection and short circuit protection.
The charge voltage for wet battery is 28.8V, floating voltage is 26.4V.
The charge voltage for gel battery is 28.4V, floating voltage is 27.0V
When the charger is in charging mode and charge current is more than 2.5A, the
CHG indicator light will be YELLOW, when charge current is lower than 2.2A, the
charger turns to maintenance mode, the CHG light is off and CHD light is GREEN.
All LED indicators will turn off when AC fails except BATT and battery type
indicator (WET or GEL).
If no battery is connected on BATTERY terminal, then there will be no output on the
terminal.
The cooling fan on the model will operate when the unit is turned on. The speed of
the fan varies depending on the temperature control circuit.
