4．Work mode introduction:
The 8KVA-12KVA OGM series inverters have two working modes: battery priority mode
(DC Priority) and mains priority mode (AC Priority).
4.1. Battery priority mode（DC Priority)：
When the battery voltage is normal, regardless of whether the mains (or diesel engine) input
is normal or not, the inverter works by inverting the battery's direct current into alternating current
to supply power to the load. When the battery voltage is too low, the inverter automatically
switches to the mains ( (Or diesel engine) to supply power to the load, but not to charge the battery.
After the battery is fully charged by the photovoltaic panel, the inverter will automatically switch
to battery inverter to supply power to the load. This mode is suitable for new energy systems such
as photovoltaic power generation and wind power generation.
(1) In battery priority mode, when the photovoltaic panel is generating electricity in sufficient
sunlight, the system works as shown in the figure below:
(2) In battery priority mode, when the photovoltaic panel does not generate electricity at night or
on a cloudy or rainy day and the battery voltage is normal, the system works as shown in the
figure below:
(3) In battery priority mode, when the photovoltaic panel does not generate electricity at night or
on a cloudy or rainy day and the battery is low, the system works as shown in the figure below:

4.2.AC Priority:
When the mains (or diesel engine) input is normal, the inverter works in the mains bypass to
supply power to the load and at the same time to the battery.When the mains power is too
high/low/severe distortion/frequency abnormality/fault and other abnormal conditions, the inverter
will automatically switch to the battery to supply power to the load. After the mains (or diesel
engine) input is normal, the inverter will be reversed. The converter will automatically switch to
the mains bypass to supply power to the load. This mode is suitable for the backup power system,
the inverter is always on, and it is suitable for the unstable mains or the need to ensure the
uninterrupted load to shorten the switching time.
(1) In the mains priority mode, when the photovoltaic panel is fully sunny and the mains input is
normal, the system works as shown in the figure below:
(2) In the mains priority mode, when the photovoltaic panel generates electricity with sufficient
sunlight and the mains input is abnormal, the system works as shown in the figure below:

(3) In the mains priority mode, when the photovoltaic panel does not generate power at night or on
a cloudy or rainy day and the mains input is normal, the system works as shown in the figure
below:
(4) In the mains priority mode, when the photovoltaic panel does not generate electricity at night
or on a cloudy or rainy day, the mains input is abnormal and the battery voltage is normal, the
system works as shown in the figure below:

instruction manual. Especially: Before starting the machine, pay attention to whether the input
voltage is normal; when operating, pay attention to whether the sequence of power on and off is
correct.
3. The equipment has automatic protection for short-circuit, over-current, over-voltage,
over-heating, etc., so there is no need to shut down manually when these phenomena occur; the
protection points for automatic protection are generally set at the factory and do not need to be
adjusted.
4. There is high voltage in the equipment cabinet, and the operator is generally not allowed to
open the cabinet door, and the cabinet door should be locked normally.
