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.

HELIOS COMBO SPH3600/5000-BL

2 Overview

12

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.

HELIOS COMBO SPH3600/5000-BL

Figure2-6 Peak shaving

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.

HELIOS COMBO SPH3600/5000-BL

2 Overview

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.
