Residential Energy Storage Solution FAQ

What is an energy storage system (ESS)?

An ESS (Energy Storage System) refers to converting electrical energy from power systems into storable electrical energy. The energy flow can then be a channel in the home electrical system to power household appliances. 

Why is an energy storage system important? 

Energy storage plays a critical role in our lives and can significantly help us create a safer and more flexible grid system. Many innovative energy systems allow you to remotely control and monitor your household energy through a mobile app. The system will charge the batteries during off-peak periods and discharge them to the load at peak hours to reduce electricity consumption. 

Is the energy storage system worth the investment?

Generally speaking, residential energy storage solutions are worth the investment. Your property can exponentially grow in value. Besides, your investment will return within few years from the installation. Your electric bills will be cut, making both you and the planet happier.

What to consider when selecting an energy storage system?

• Product operation type
• Average usage/day
• System size profile
• Life span
• Charge efficiency / minimum charge

Here a general picture to understand which is the optimal device for you based on average usage and size profile.

1. Young Adults: 

Utilization focused early in the morning and evenings. More usage during the day on weekends.

Average usage 20kWh per day

Optimal Solar System Size: 5kWh

2. Retirees: 

Usually at home during the day. Heating and cooling system through day and night.

Average usage 30kWh per day

Optimal Solar System Size: 6.6kWh

3.Extensive Energy User: 

Warehouse, Swimming pool, commercial buildings. Electronic devices operate through summer and winter.

Average usage 50kWh per day

Optimal Solar System Size: 13kWh

How does an energy storage system (ESS) work?

An energy storage system (ESS) is a complex equipment that can control and store the electricity flows in the power system. The power source is an indispensable part of ESS. The most common power source used in ESS is solar energy.

Another critical component is an inverter. The inverter can convert DC to AC and feeds to the grid. Thus, the power can be used in household appliances. 

The core of the ESS is the battery. This component stores the incoming energy or electricity from the power system and discharge later when needed. A battery will have a maximum capacity and needs various times to charge fully.

The energy monitoring system acts as a sensor in the energy storage system, enabling users to visualize all the power flow through the ESS. More importantly, it knows how much energy is consumed from the grid, the battery information, and the consumption pattern. This system allows users to monitor the real-time performance of ESS through a mobile app. Any system failure will be detected instantaneously and reported to users. 

What is a Lithium battery?

Lithium batteries refer to “Lithium Iron Phosphate” batteries with lithium iron phosphate as the positive material. The cathode materials of lithium-ion batteries mainly include cobaltic lithium acid, lithium manganate, lithium nickel acid, ternary materials, and lithium iron phosphate. Among them, lithium cobaltite is the cathode material used by the vast majority of lithium-ion batteries.

What are the main advantages of using lithium batteries?

1. Long life
2. Safe use
3. Fast charging
4. High-temperature resistance 
5. Large capacity
6. No memory loss effects
7. Environment friendly
8. Pow price

What are the benefits of energy storage systems?

Reduce Electricity Bills 

Adding an energy storage system to your home can effectively reduce the electricity bill. Installing an energy storage system will keep the total power consumption below a specified value. With on-site storage, you can charge your batteries whenever electricity rates are at their lowest (during off-peak hours or with your free solar energy). 

Maximize Self-Consumption

The energy storage system can perfectly suit commercial and residential uses. During the daytime, the system can collect and store the energy, which can be used at night whenever needed. Property owners are provided with the most efficient use of solar energy at home, including grid independence, increased self-consumption, and reduced electricity bills.

Emergency Power Backup

Don’t worry about the sudden power failure. Residential energy storage solutions integrated with solar panels can ensure energy backup. The backup power system is used to provide energy when the primary source fails for 7 * 24 power supply.
