Q: What are home energy storage systems?
A: Home energy storage systems are gaining popularity as battery and solar panel costs decrease. Typically, these systems include photovoltaic systems, batteries, and inverters. The photovoltaic system generates electricity from sunlight, stored in batteries. Inverters convert stored DC electricity into AC electricity for home use. These systems offer advantages like generating your own electricity, reducing reliance on the grid, and saving on energy bills.


Q: Bonnen home energy storage technical specifications.
A: Bonnen provides two types of residential energy storage systems. Our first option offers either wall-mounted or stand-mounted batteries with capacities of 5.12kWh and 10.24kWh, typically compatible with inverters ranging from 3KW to 7KW. You have the flexibility to choose your preferred inverter brand, or alternatively, you can opt to purchase home batteries separately.
Additionally, we provide an all-in-one stack system. Bonnen has developed both low-voltage and high-voltage stack systems, allowing buyers to select the desired voltage and power. The modular design of the high-voltage battery system enables stacking of 3 to 7 battery modules, with capacities ranging from 15.36 KWH to 35.84 KWH and voltages from 153.6V to 358.4V. This system is equipped with an output inverter rated between 8KW to 12KW.


Q: What does a bonnen home energy storage battery do?
A: A Bonnen Home Energy Storage System (HESS) serves multiple purposes. It stores solar energy generated during the day for nighttime use, ensuring continuous power supply. Additionally, it acts as a backup power source during grid outages. Depending on your location and local electricity rates, the home battery can potentially save you money by allowing you to shift energy consumption from high-rate to low-rate periods. Lastly, it empowers you to take control of your energy usage and achieve self-sufficiency from the grid.

Q: Can I determine the charging priorities for my home energy storage battery?
A: Yes, you have the option to set charging priorities based on your preferences:
Self-Powered: Utilize the stored energy from your solar system to power your home after sunset.
Backup Only: Reserve all the energy in your home battery for emergency backup power during periods of low or no sunlight.
Balanced Time-Based Control: Power your home after sunset while avoiding costly on-peak electricity rates by utilizing the electricity stored in your solar system.


Q: Is solar panel installation required to use the Bonnen home energy storage system?
A: No, it is not necessary to have PV/solar panels to operate the Bonnen Home Energy Storage System. The home energy storage battery, also known as Powerwall, can be charged using AC power from the grid or a generator. Bonnen offers an all-in-one package that includes household batteries and inverter systems, with the option to include solar photovoltaic systems upon request. Solar panels can be used for load transfer or as a standby power supply, but they are not mandatory for the operation of the system.


Q: Where should I install the home battery energy storage?
A: Typically, the home battery energy storage is installed either outdoors or in a utility room such as a garage or basement. Factors to consider include heat dissipation, ventilation requirements, avoiding direct sunlight exposure, and protection against water exposure.


Q: How does a home battery connect to my home?
A: Prior to connecting a battery to the grid, it's important to install a separate AC breaker between the inverter and the AC input power source. This ensures that the inverter can be safely disconnected during maintenance and is fully protected from overcurrent. For hybrid-coupled homes, before making connections to the Grid, Load, and Gen ports, ensure that the AC breaker or disconnector is turned off.


Q: What's the difference between single-phase and three-phase electricity?
A: Single-phase electricity, typically found in households, operates at either 230 or 240 volts, while three-phase electricity is commonly used in commercial and industrial settings and operates at either 400 or 415 volts. One notable distinction between single-phase and three-phase electricity is the power transmission capacity. Three-phase electricity can transmit more power than single-phase electricity, making it suitable for high-powered applications. Additionally, three-phase electricity tends to experience fewer power fluctuations compared to single-phase electricity.


Q: Which is better for my home solar system: single-phase or three-phase?
A: Single-phase systems are typically preferred for residential homes, whereas three-phase systems are commonly used in commercial and industrial environments. If you're uncertain about the phase of your system, you can usually locate this information on your electrical panel.


Q: How much power do I need for my home battery energy storage?
A: We recommend selecting only essential appliances to be connected to the battery, such as a refrigerator, a few phone charging sockets, lights, and the wifi system. During a complete blackout, a typical 10 kWh battery can provide power for approximately 10 to 12 hours, depending on the load it is supporting. For instance, a 10 kWh battery can run a refrigerator for 14 hours, a television for 130 hours, or a single LED light bulb for 1,000 hours. Therefore, many households opt for a battery with a storage capacity of 10 kilowatt-hours. Before purchasing a battery storage system, it is crucial to discuss your requirements with our system designer.


Q: How long does a home energy storage battery last on one charge?
A: The duration of a home energy storage battery's charge depends on your electricity usage. The more household appliances in use, the shorter the battery's lifespan on a single charge. For example, with basic consumption and lighting, a battery may last approximately 12 hours. Bonnen engineers will design and calculate the battery capacity based on your historical electricity consumption data.


Q: How long will it take to fully charge my home energy storage battery?
A: The time it takes to fully charge your home energy storage battery depends on various factors such as sunlight duration, brightness, shading, outside temperature, etc.


Q: Does my home energy storage system automatically switch on during grid failure?
A: Yes, the Bonnen Home Energy Storage System will automatically switch to battery power in the event of a grid failure.


Q: How long do batteries last?
A: Lithium-ion batteries typically endure around 6000 cycles (charges/discharges) at an 80 percent discharge rate, translating to an expected lifespan of over 10 years for high-performance systems if cycled once per day. Bonnen LiFePO4 batteries are designed to last over 15 years.


Q: What is the minimum order quantity (MOQ) for bonnen?
A: In fact, there is no minimum order quantity for Bonnen home energy storage systems. Bonnen welcomes distributors, resellers, PV installers, and system contractors as its target customers. Even a single sample order is welcomed. Let Bonnen assist in expanding the ESS market and enhancing your profitability!
