This is a set of integrated systems combining a hybrid inverter with energy storage battery, which could connect the grid and solar PV as the source of electricity. Solar panels will produce energy during the day for self-consumption and charge batteries. The energy storage system will output energy to power supply the load during the night.
Different from traditional PV generation, the significance of SCU PV generation + ESS solution is solving technical difficulties, diversified income, and additional value-added functions.
Key features:
a)Power dynamic increase
When you need a power supply capacity increase, there will be slow process, long time and high cost. Energy storage could be a better solution.
b)Peak shaving
With the deepening of power reform, the expansion of peak valley price difference will become a trend.
c)Improving power quality
By dynamically adjusting reactive power, the reactive power loss is compensated. The reactive power can be adjusted to more than 0.95.
d)Self-consumption
Using solar energy to generate electricity, saving and earning you money.
Working modes:
On-grid mode：
When load is larger, the load can be supplied by Solar, genset, or genset+battery.
Off-grid mode:
When the load is smaller, the genset could be off and the load is powered by battery only.
- BAT SOC>Setting point, PV>Load: Firstly, Load supply, then extra energy can be stored in BAT
- BAT SOC>Setting point, PV<Load: PV+BAT together to supply the load
- BAT SOC<Setting point: DG started through Dry contact, Firstly Load supply, then extra energy can be stored in BAT.
Benefits
- Saving diesel generator investment, the load can be supplied by genset+battery.
- Saving diesel consummation, the genset can be off when the load is small and powered by battery.
- Solar energy consumption, store the extra solar energy and use it at night time.
- 24/7 uninterrupted power supply and seamless switching make sure the load will not lose.
