1.GENERAL INTRODUCTION
1.1 System Introduction
WH-SPHA series hybrid all-in-one battery energy storage system (BESS) is designed
for both indoor and outdoor use. BESS can store the DC power generated by the PV
array into the battery, or convert it into AC power to loads. This user manual applies
to the following products: WH-SPHA3.6H-5.12kWh/WH-SPHA3.6H-10.24kWh/WH-
SPHA4.6H-5.12kWh/WH-SPHA4.6H-10.24kWh/WH-SPHA5.0H-5.12kWh/WH-
SPHA5.0H-10.24kWh/WH-SPHA6.0H-5.12kWh/WH-SPHA6.0H-10.24kWh.
1.2 Safety Introduction
1.2.1 Protection of Warning Sign
●SYMBOLS EXPLANATION

6
●SAFETY WARNING
Any installation and operation on BESS must be performed by qualified electricians,
in compliance with standards, wiring rules or requirements of local grid authorities
or companies (like AS 4777 and AS/ NZS 3000 in Australia).
Before any wiring connection or electrical operation on BESS, all battery and AC
power must be disconnected from BESS for at least 5 minutes to make sure BESS is
totally isolated to avoid electric shock.
The temperature of BESS surface might exceed 60℃during working, so please make sure
it is cooled down before touching it, and make sure the BESS is untouchable for children.
Usage and operation of the BESS must follow instructions in this user manual,
otherwise the protection design might be useless and warranty for the BESS will be
invalid.
Do not open BESS cover or change any component without WIFO PRO ’s
authorization, otherwise the warranty commitment for the BESS will be invalid.
Appropriate methods must be adopted to protect BESS from static damage. Any
damage caused by static is not warranted by WIFO PRO.
The neutral continuity is NOT maintained internally, it must be achieved by external
connection arrangements like in the system connection diagram for Australia on page 31
section 2.3.3.
This BESS includes an integrated residual current device (RCD).
If an external residual current device (RCD) is used, a device of type A should be used, with
a tripping current of 30 mA or higher.
This BESS uses active anti-islanding protection, the method is shifting the frequency of the
inverter away from nominal conditions in the absence of a reference frequency (frequency
shift).
This BESS is a multiple mode inverter, it is used for outdoor unconditioned without solar
effects. The maximum operating ambient temperature is 55 ℃.
Product should not be used in multiple phase combinations.
In the event of an earth fault, an error message will be sent to eCactus App and the status
lamp on our product will turn into red.
