Switch Off; Emergency Procedure - Rayleigh Instruments RI-ENERGYFLOW-3P-MODULAR RI-ENERGYFLOW-HYBRID User Manual

S t e p 3 : Turn on the external PV switch.
S t e p 4 : Turn on the external grid switch.
S t e p 5 : If backup load is applied, turn on the external Backup switch.
NOTE:
The Backup switch is only used when a backup load is applied.
S t e p 6 : Open the battery switch cover and turn on the battery switch on the cable
box of inverter.
S t e p 7 : Close the battery switch cover and the outer shell of the cable box.
NOTE:
If PV=0V under sunshine, please check whether PV is connected reversely or
whether the circuit is normal.
NOTE:
Appliances such as air conditioner are required at least 2-3 minutes to restart because it is
required to have enough time to balance refrigerant gas inside of circuit. If a power shortage
occurs and recovers in short time, it will cause damage to your connected appliances. To
prevent this kind of damage, please check manufacturer of air conditioner if it is equipped
with time-delay function before installation. Otherwise, this inverter will trigger overload fault
and cut off output to protect your appliance but sometimes it still causes internal damage to
the air conditioner.

3.3 Emergency Procedure

When the E8KT/E10KT/E12KT energy storage system appears to be running abnormally,
you can turn off the grid-connected main switch that directly feeding the BESS, and turn
off all load switches within the BESS, turn off the battery switch at the same time. To
prevent a potentially fatal personal injury, if you want to repair or open the machine after
the power is switched off, please measure the voltage at the input terminals with a suitably
calibrated voltage tester. Before working on this equipment, please confirm that there is no
