Residential Energy Storage System Solution Application Scenarios

During peak electricity demand periods, concentrated usage from commercial, industrial, and residential users often strains the grid, risking overloads. PV energy storage systems reduce reliance on grid power by discharging stored energy, easing the load on transformers and other grid infrastructure to avoid overload tripping. This is particularly beneficial for factories expanding production but facing delays in grid capacity expansion. Additionally, they serve as “flexible regulators” for urban power grids—pilot projects in a megacity showed a 25% improvement in regional grid stability.

Basic System Introduction:

PV Module: Converts light energy into DC power to charge the battery via the all-in-one machine, or directly inverts it into AC power to supply loads.
Mains or Generator: Connected to the AC input terminal, it can power loads and charge the lithium battery at the same time. If no mains or generator is connected, the system can still operate normally, with loads powered by the battery and PV modules.
Solid State Battery: Ensures normal power supply to system loads when solar energy is insufficient and no mains power is available.
Household Loads: Various household and office loads can be connected, including AC loads such as refrigerators, lights, TVs, fans, and air conditioners.
Inverter-Controller All-in-One Machine: The energy conversion device of the entire system.
The specific system wiring method is determined by the actual application scenario.

Residential Homes:
Balcony PV Energy Storage + Wall-Mounted Units, a Self-Sufficient Home Energy System. Standalone PV systems have time-dependent power generation limitations—high output during daytime peak sunlight often coincides with low household/enterprise electricity demand, leading to significant energy waste or feed-in at low grid prices. Conversely, PV generation ceases during evening peak usage, forcing reliance on grid power at premium rates. PV energy storage systems store surplus daytime electricity for release during peak demand, boosting PV utilization from 65%-75% to over 90%. Additionally, they leverage time-of-use (TOU) electricity price differences by charging during off-peak hours and discharging during peak periods.

FAQ

1) Charging Mode

PV Priority
Charging is prioritized by PV power; mains charging starts only when PV power is unavailable. Solar power is fully utilized during the day, and charging switches to mains power at night to maintain battery capacity. It is suitable for areas with a relatively stable grid and high electricity prices.
Mains Priority
The battery is charged by mains power first; PV charging starts only when mains power is unavailable.
Hybrid Charging
PV and mains power charge the battery in combination. PV MPPT charging is prioritized; mains power supplements charging when PV energy is insufficient and stops when PV energy is adequate. This method offers the fastest charging speed, making it suitable for areas with an unstable grid to ensure sufficient backup power at any time.
PV Only (Only Solar)
Charging is performed solely by PV power without activating mains charging. This is the most energy-efficient mode, as all battery power comes from solar energy. It is typically used in areas with good sunlight conditions.

2)Power Supply
PV Priority Mode
Switches to mains power supply and charging when PV power is unavailable. This mode maximizes the utilization of solar energy while maintaining battery capacity, suitable for areas with a relatively stable power grid. The power supply priority order is: PV → Mains → Battery.
Mains Priority Mode
Switches to battery inverter power supply only when mains power is unavailable, and switches to mains power for charging and supply when mains power is available. The device functions as a backup UPS, suitable for areas with an unstable power grid. The switching does not affect PV charging. The power supply priority order is: Mains → PV → Battery.
Inverter Priority Mode
Switches to mains power supply only when the battery voltage drops below the set point (Setting 04), and switches back to battery discharge mode when the battery voltage charged by mains power rises above the set point (Setting 05), realizing cyclic battery charging and discharging. This mode maximizes the use of DC power, suitable for areas with a stable power grid. The switching does not affect PV charging. The power supply priority order is: PV → Battery → Mains.

Answer: Solar energy storage supports dual charging from mains power and solar energy, and can supply power independently off-grid. It has larger output power and longer battery life, suitable for long-term backup power for home and outdoor use. Ordinary UPS is mainly used for power-off delay protection of computers and other equipment with short battery life. Ordinary power banks have low power and cannot drive high-power equipment such as household appliances and power tools.

Answer: Semi-solid lithium batteries have higher safety and stronger thermal stability, which are not easy to bulge or catch fire. They have longer cycle life and higher energy density, with larger capacity under the same volume. They are also more environmentally friendly, meeting the long-term use needs of new energy storage products.

Answer: Pure sine wave output has the same waveform as mains power, which is compatible with refrigerators, air conditioners, motor household appliances, precision electronic equipment, without noise or equipment damage. Non-sine wave (modified wave) may cause unstable operation of some electrical appliances, generate noise, and even damage sensitive equipment.
