3.4.2 Inner component layout
Inner component layout is shown in below figure:
DC/AC breaker
The AC main switch can be used to disconnect the AC side of the inverter from the
grid. The DC main switch can be used to make the DC side of the inverter
disconnected from the battery assembly. If you use AC main breaker under load , the
components of the inverter will be subjected to considerable stress. Frequent use of
the AC main switch can result in individual components damage due to stress and
may cause inverter failure.
Fuse
There is a mark on the fuse holder, the mark turns red indicates that the fuse is
damaged; professional technicians are required to check the cause of the damage of
the fuse and then replace the fuse.
3.5 working mode
HPS5000TLS/HPS7500TLS/HPS10000TLS is designed with flexible working modes:
3.5.1. Off-grid mode
(1)When PV power is higher than load power, PV supply priority to load power,then
to the battery charge.
(2) Battery discharge automatically when PV power is lower than load power.
3.5.2 Grid-connected load priority mode
(1) Make full use of PV power. When the PV power is insufficient, the battery is given
priority for the load, and the second grid is used for the load.
(2) This mode has two situations: anti-backflow and no backflow prevention. PV
power meets charging power and load to prevent power feeding to grid.
(3) Working status:
A. When the PV power is greater than the load power, the PV preferentially supplies
power to the load, and the residual power is charged to the battery;
B. When the PV power does not meet the load, the battery is automatically
discharged. If the battery is discharged to the undervoltage protection point, the PV
and the grid together supply power to the load. To protect the battery, the PV side will
use a small amount of power to charge the battery, and the battery can be recharged
to a certain extent to restore power.
3.5.3 On-grid backup priority mode
(1) Grid supplies power to load and charges battery when PV power insufficient.
(2)When the back-flow-prevention works, PV power can meet battery charge and
load power.
(3) operation state
A.PV supply priority to the load, the remaining to load and grid when PV power is
higher than load power
B. When PV power is lower than the charging power, PV supply priority to battery,
the grid supplies to load and battery.

3.5.4 On-grid economic priority mode
(1)At this mode, the inverter can prevent the current from flowing back by default, PV
will only need to meet battery charge and load power.
(2)Valley price: working logic is the same to the backup priority mode’s. PV and grid
supply priority to battery, the remaining to load.
(3)Fair price:
A. Battery can neither discharge nor be charged by grid.
B.PV power supply priority to load, the remaining to battery when PV power is higher
than load power.
C. When PV power is lower than load power, PV and grid supply to load, PV does not
charge battery
(4)Peak price:
A. Grid will not charge battery.
B. When PV power is higher than load power, PV supply to load , the remaining to
battery.
C. When PV power is lower than load power, there are two conditions:
a. When battery voltage is normal, PV and battery supply to load.
b. When the battery is under voltage, battery will not discharge, PV and grid supply to
load only, not to battery.
3.5.5 On/Off-gird switch
Operation logic: When grid power on, HPS can switch into on-grid mode
automatically; when grid power off, HPS can switch into off-grid mode automatically.
3.5.6 Fault mode
When the Hybrid energy system fails, the inverter will immediately disconnect the
AC/DC contactor and enters into the fault mode, so as to ensure the safety of the
system. Inverter continuously monitors fault status and will not enter charge and
discharge mode until the fault is eliminated.
3.5.7 Permanent fault mode
When the Hybrid energy system is in serious failure, the inverter will immediately
disconnect the AC/DC contactor and enters into the Permanent fault mode, so as to
ensure the safety of the system. For example: inverter module failure etc. please
contact your local dealer or ATESS directly when inverter enters permanent fault
mode, repairmen on site is not allowed without authorization of ATESS.
3.6 Battery setting
Battery is an important part of energy storage system, strict protection is needed in
the whole operation process. Protection threshold need to be set on HPS10 to
ensure safe operation of battery, parameters including: battery quantity and unit
quantity, capacity, charge current, discharge current, over voltage protection, under-
voltage protection and so on. Battery parameter setting need to be done by
professional personnel. Improper setting of battery will affect the normal
