•
•
In case of flooding
Stay out of the water if any part of the Battery Module, Hybrid Inverter, or wiring is
submerged.
Turn off EP Cube. (Refer to Page 13)
If possible, protect the system by finding and stopping the source of the water and
pumping water away.
If the EP Cube service team has confirmed that it is safe to re-energize, let the area
dry completely before use.

SAFETY INSTRUCTIONS
CAUTION
The transportation, installation, and commissioning of the EP Cube must be carried
out under the specified conditions. Do not expose EP Cube outside these specified
conditions.
EP Cube can only be installed, repaired, replaced, and maintained by licensed
authorized personnel for safety and warranty purposes. Personnel must wear protective
equipment during any operations.
Do not place foreign objects on top of the product or insert them anywhere in the
product. Make sure there is enough space on top of EP Cube for ventilation.
Do not stack battery modules more than the specified quantity or reverse the polarity
of the battery.
Be careful to protect EP Cube from impact when installing EP Cube in a garage or near
vehicles.
Operating or placing in high temperatures, and near heating equipment or sources of
extreme heat will cause the battery modules to be thermally unstable, thereby exceeding
the thermal runaway point of its material and potentially causing a fire.

EP Cube has different operation modes: Self-Consumption and Time Of Use. The
owner can select a desired operation mode for daily use according to the descrip-
tion shown in the chart below.
DescriptionsOperation Modes
Self-Consumption
Time Of Use
Store surplus solar energy in the battery modules, and manage it to
discharge to support load when solar power is not enough.
Owner can set peak time and off-peak time on app based on local utility
Time Of Use billing mechanism, to save on electric bill.
Operation Mode
During self-consumption mode power generated by PV is utilized to supply power
to connected loads as a priority. Any surplus power is then used to charge the
battery modules. Only once battery modules are fully charged, power is exported to
grid. In an instance when power generation by PV is lesser then load consumption,
battery modules discharge to support loads. Once the battery modules SOC
reaches set value for reserve SOC, then loads are supported by grid power.
PV Power Usage Priority: Load > Battery > Grid.
Load Energy Source Priority: Photovoltaic > Battery > Grid
Battery Charging Source: PV only

During TOU mode user can set off-peak, peak and peak hours. 3 time-slots can be
set for each category.
During Off peak hours, EP CUBE can only be charged from PV as priority power
source. If PV power is not in excess then user can allow to charge the EP CUBE with
low price electricity from grid during off peak hours in order to ensure full charge
before peak hours.

During peak hours, EP CUBE supports the load’s power consumption from PV
power and battery to avoid use of high price electricity from grid. Loads are
supported by PV, and battery as priority power sources and excess consumption is
supported by grid. During peak hours, system operation is consistent with “Self
Consumption” mode.
