alarm will go off to inform users of the low voltage.
t7: As the battery voltage falls as low as 10 volt and the utility works normally, the
MCU will detect this and enter the bypass mode supplying electricity to the load. In
the meantime the AC charger and solar charger keep charging the battery to prevent
the unit from switching off. Also, the solar charger will be turned ON if the solar
current is higher than 8A to achieve the goal of energy saving.
t8: When the battery is fully charged by the AC charger and solar charger (battery
voltage around 15 volt), both chargers will be turned OFF to prevent overcharging.
t9: Once a power cut occurs, the MCU will switch to the inverter mode (<15ms) to keep
loads running.
t10: When the battery drops below 12.8 volt, the MCU will once again start up the solar
charger instead of the AC charger in order to save energy.
t11: As the battery voltage falls as low as 10 volt and the utility remains unavailabe, the
battery will be charged by only the solar charger. Then the battery will discharge
very fast since the inverter continues supplying power through it. The inverter mode
eventually shut down to prevent over discharging.
t12: If the solar charger current is more than 8A and the utility is not available at the
same time, the power to the battery is provided by the solar charger. As soon as the
battery reaches 15 volt again, the soalr charger will be turned OFF simultaneously.
