3 PRODUCT INTRODUCTION
3.1 BRIEF INTRODUCTION TO PRODUCT
EOV is a new generation of household energy storage system with two output specifications of
220V and 110V, which can meet the diversified needs of global users. The EOV energy storage
system adopts a modulardesign, including power modules and battery expansion modules, so it
can be easily combined into a system of any capacity required by the user
The lithium iron phosphate batteries with high performance and long service life are used in the
energystorage module. Meanwhile, the modular structure design is adopted. Each energy storage
module is internallyintegrated with the intelligent BMS system, which can be easily expanded and
can be combined into 20KWH battery pack at most.
The brand new topological circuit design is adopted in the power module, which can realize the
energy exchange between photovoltaic, mains, battery and loads, and has the function of
photovoltaic and mains charging. The photovoltaic charging module adopts the latest optimized
MPPT tracking technology, which can quickly track the maximum power point of the photovoltaic
array in any environment, and obtain the maximum energy of the solar panel in real time. In
addition, MPPT has a wide voltage range. The advanced control algorithm is adopted in the mains
charging module to realize the fully-digital double closed-loop control of voltage and current, so
the control precision is high and the volume is small. The AC voltage input range is wide,and the
input/output protection functions are complete, which can realize the stable and reliable charging
and protection of batteries. The inverter module is based on the full-digital intelligent design,
adopts the advanced SPWM technology, outputs pure sine wave, converts direct current into
alternating current, and is applicable for household appliances, power tools and other AC loads.

system,which can solve the problem of electricity consumption in areas without electricity.

4.1 APPLICATION SCENARIOS

4.1.1 APPLICATION SCENARIOS WITH ONLY MAINS POWER BUT NO
PHOTOVOLTAIC
When the mains is normal, it charges the battery and supplies power to the loads.

-8-
When the mains is disconnected or stops working, the battery supplies power to the load through
the power module.

4.1.2 APPLICATION SCENARIOS WITH ONLY PHOTOVOLTAIC BUT NO MAINS

POWER
During the day, the photovoltaic directly supplies power to the loads while charging the battery.

At night, the battery supplies power to the loads through the power module.

At night, the mains supplies power to the loads, and continues to charge the battery, if the battery
is not fully charged.

If the mains is disconnected, the battery supplies power to the loads.

4.1.3 COMPLETE APPLICATION SCENARIOS

During the day, the mains and photovoltaic simultaneously charge the battery and supply power
to the loads.

8.6 BATTERY EQUALIZATION DESCRIPTION

Equalization function is added into charge controller, lt reverses the buildup of negative chemical
effects like stratification, a condition where acid concentration is greater at the bottom of the
battery than at the top. Equalization also helps to remove sulfate crystals that might have built up
on theplates. lf left unchecked, this condition, called sulfation, will reduce the overall capacity of
the battery.Therefore, it's recommended to equalize battery periodically.

HOW TO APPLY EQUALIZATION FUNCTION

You must enable battery equalization function in monitoring LCD setting program 30 first.
Then, youmay apply this function in device by either one of following methods:
1.Setting equalization interval in program 35.
2.Active equalizationimmediately in program 36.

WHEN TO EQUALIZE
In stage, when the setting equalization interval(battery equalization cycle) is arrived,
or equalization is active immediately, the controller will start to enter Equalize stage.

EQUALIZE CHARGING TIME AND TIMEOUT
In Equalize stage, the controller will supply power to charge battery as much as possible until
battery voltage raises to battery equalization voltage.Then.constant-voltage regulation is applied
to maintain battery voltage at the battery equalization voltage. The battery will remain in the

However, in Equalize stage, when battery equalized time is expired and battery voltage doesn't
rise to battery equalization voltage point, the charge controller will extend the battery equalized
time until battery voltage achieves battery equalization voltage. If battery voltage is still lower
than battery equalization voltage when battery equalized timeout setting is over, the charge
controller will stop equalization and return to float stage.
