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.
C 20%If battery is not discharged at this mode or inverter switched to other mode,
float charge after one week, then discharge battery
