2 Overview
This chapter introduces the inverter intro and its operating mode.
2.1 Product Intro
SPH-BL(3600-5000) series inverter is PV energy storage inverter, which mainly applies for household
energy storage system, as shown in Figure2-1.
The household energy storage and management system consists of energy storage inverter, PV array,
batteries, grid, and smart meter(optional), which allows customers to reduce their dependence on grid
and even become energy self-sufficient. The system can achieve an optimal match between the PV
generation, loads and grid and at the same time guarantee the stability of the grid. Moreover, the system
can provide back-up power for important household appliances in case of a power outage.

2.2 Operating mode
The inverter status can transfer automatically between grid-connected and off-grid mode according to
grid status. In the grid-connected status, there are four operating modes: self-consumption priority,
battery storage priority, peak shaving and energy shift scheduling. When grid is abnormal or failure,
inverter will work in the off-gird emergency mode.
Self-consumption priority
When the energy generated by PV array is sufficient, PV array will supply power for load in advance,
the remaining energy will charge battery. If there still has remaining energy, it will be supplied for grid-
connection generation. When the energy generated by PV array is insufficient, PV array and battery
will supply power for load in advance, as shown in Figure2-4.
Figure2-4 Self-consumption priority
Battery storage priority
If battery doesn't charge fully, PV array and grid will charge battery fully in advance to meet the
emergency power requirements of key loads. When the energy generated by PV array is sufficient
(more than charging energy), it will charge battery in advance, the remaining energy will be supplied
for load. If there still has remaining energy, it will be supplied for grid-connection generation, as shown
in Figure2-5.

Figure2-5 Battery storage priority
Peak shaving
If the electricity price makes a big difference in the peak and valley time (In the valley time, the
electricity price of grid-connected generation is cheaper than PV array generation, in the peak time, the
electricity price of grid-connected generation is cheaper than PV array generation), user can set the
charging time and discharging time of battery by WiseEnergy(Equipped monitoring software for PC).
In the peak time, set to battery discharging mode(for household used);in the valley time, set to battery
charging mode to charge battery, as shown in Figure2-6.
User not only can make full use of PV array generation, but also can use electricity price difference in
the peak and valley time properly to improve power consumption strategy and save electricity, which
can provide more economic self-consumption power supply plan.

Energy shift scheduling
If the electricity price makes a big difference in the peak and valley time(In the valley time, the
electricity price of grid-connected generation is cheaper than PV array generation, in the peak time, the
electricity price of grid-connected generation is more expensive than PV array generation), user can
set the charging time and discharging time of battery by WiseEnergy(Equipped monitoring software
for PC). In the peak time, set to battery discharging mode(Except household used, the remaining energy
will be supplied for grid-connection generation.); in the valley time, set to battery charging mode to
charge battery, as shown in Figure2-7.
User not only can make full use of PV array generation, but also can use electricity price difference in
the peak and valley time properly to improve power consumption and generation strategy and save
electricity, which can provide more economic self-consumption power supply plan and get more
benefits.
Generally, in the energy shift scheduling mode, the battery capacity should be more than 3-4 times of
rated power.

Figure2-7 Energy shift scheduling
Off-grid emergency mode
When grid abnormal or failure, inverter will work in the off-gird emergency mode. The inverter can be
regarded as back-up power to supply power for major load, as shown in Figure2-8.
In the off-grid emergency mode, the remaining power supply time depends on battery capacity, load
and battery remaining energy when grid failure. Set to the corresponding working mode according to
different emergency requirements, which is to avoid affecting emergency power supply time for battery
remaining energy isn't enough.
