Status
t1: When user turns on the ISI-501, battery voltage will be sensed. If battery
t2: While the ISI-501 operates, battery voltage will slowly drop; when battery
t3: If the power provided by the PV module is greater than the load consumption,
t4: When battery voltage drops to 13/26/52V again the charger will automatically
，
t5: If the power provided by the PV module is less than load consumption, even
t6: If the charger continuously charges the battery, the battery voltage will slowly
t7: Same action as t3.
voltage is greater than 13/26/52V, it means the battery is adequately charged
and the charger circuit will remain de-activated to prevent overcharging.
voltage is lower than 13/26/52V, battery low signal will be detected and the
charger will automatically activate and charge accordingly.
the battery voltage will increase. When this battery voltage reaches 14.4/28.8/
57.6V, the charger circuit will stop charging the battery modules to prevent the
batteries from overcharging.
restart the charging action.
if the charger is operating, the battery voltage will still drop. When battery
increase. When battery voltage reaches 13/26/52V, the system will re-power
The status of the inverter changes depending on the power provided by the
PV module and its load consumption.
on after three minutes and start providing AC voltage output.
voltage is below 10.5/21/42V, the ISI-501 will shut down to prevent the battery
from over discharging thereby increasing its lifetime.
