Brief Introduction to Working Principle:

The controller has the function of intelligent charging management for the electricity from solar photovoltaic array to battery, achieving high accuracy rate control through micro-chip’s sampling and calculation for battery terminal voltage, ambient temperature and other parameters related to the battery capacity. With adopting high efficiency PWM battery charging mode to the controller, battery working is ensured to be the in the best state to extend the battery life.

The inverter is an AC power supply that provides multiple protection. It can not only convert the DC energy stored in the battery to AC output to the load, but also output the main power to the load through the internal static and dynamic switch automatically, at the meantime also recharging the battery. Note: The charging function is optional, which should be determined based on specific application requirements.

The inverter uses the power from the solar photovoltaic array,firstly in the battery working mode and AC output running state. When the PV array provides more energy than the load energy, the PV array provides energy to the loads energy, at the same time, the remainder stores in the battery. When the energy provided by the PV array is not enough to load the working energy, the energy provided by the PV array is all delivered to the load, and insufficient energy is provided by the battery. When this condition persists,like the midnight time, when the energy of the battery drops to the low voltage alarm threshold (single 12V battery <10.5V), the power supply of the load is automatically switched to the mains system, then electricity is supplied by the mains, at the time the battery is in recharging. When the battery is added to the full threshold (single 12V battery> 13.6V), the inverter will automatically work charging by battery, at this time the AC output is in the running state, the load energy provided by the PV array and the battery, the electricity is in the standby state.
