Home energy storage systems are becoming increasingly popular as the costs of batteries and solar panels continue to fall. A home energy storage system typically consists of a photovoltaic system, batteries, and inverters. The photovoltaic system produces electricity from sunlight, which is then stored in the batteries. The inverters convert the stored DC electricity into AC electricity, which can then be used to power your home. Home energy storage systems offer a number of advantages, including the ability to generate your own electricity, reduce your reliance on the grid, and save money on your energy bills.

MUST I HAVE PV/SOLAR TO OPERATE BONNEN HOME ENERGY STORAGE SYSTEM?
No. Home energy storage battery (or call Powerwall) can be charged with AC power from the grid or generator. Bonnen also provides an all-in-one pack including household batteries, inverter systems, and solar photovoltaic is optional per your request, and can be used for load transfer or standby power supply.
WHERE SHOULD I INSTALL THE HOME BATTERY ENERGY STORAGE?
Usually installed outdoors or in a utility room (e.g. garage or basement) –Consider the heat dissipation, ventilation –Consider no direct sunshine –Consider water showering
HOW A HOME BATTERY CONNECTS TO MY HOME?
Before connecting a battery to the grid, please install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from overcurrent. If it’s a hybrid coupled homes, before making Grid, Load and Gen port connection, be sure to turn off the AC breaker or disconnector first.WHAT’S THE DIFFERENCE BETWEEN SINGLE-PHASE AND THREE-PHASE ELECTRICITY?
Single-phase electricity is the most common type found in households, either connected at 230 or 240 volts; while three-phase electricity is typically used in commercial and industrial settings, either connected at 400 or 415 volts. One key difference between single-phase and three-phase electricity is the amount of power that can be transmitted. Three-phase electricity can transmit more power than single-phase electricity, making it ideal for high-powered applications. Additionally, three-phase electricity is less likely to experience power fluctuations than single-phase electricity.
SHOULD I CHOOSE SINGLE-PHASE OR THREE-PHASE TO APPLY TO MY HOME SOLAR SYSTEMS?
Single-phase systems are more common in residential homes, while three-phase systems are more common in commercial and industrial settings. If you’re not sure which phase your system is in, you can usually find this information on your electrical panel.
HOW MUCH POWER DO I NEED FOR MY HOME BATTERY ENERGY STORAGE?
We suggest you typically chose only their most important appliances to be connected to the battery, such as a refrigerator, a few sockets to charge phones, lights, and the wifi system. In the event of a total blackout, power stored by a typical 10 kWh battery will last from 10 to 12 hours, depending on what the battery is being asked to power. 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 most households choose a battery with 10-kilowatt hours of storage capacity. Sure before you purchase a battery storage system it is important to discuss your needs with our system designer.
HOW LONG DOES A HOME ENERGY STORAGE BATTERY LAST ON ONE CHARGE?
This is up to your loading status, the more house electric appliance used, the less time can be last. Let’s say a lasting 12 house is normally achieved by using some lights and basic consumptions. Bonnen engineer will design and calculate based on your history of electricity consumption data.
HOW LONG WILL MY HOME ENERGY STORAGE BATTERY BE CHARGED FULLY?
This is related to many factors, such the sunshine time, brightness, shading, outside temperature etc.
DOES MY HOME ENERGY STORAGE SYSTEM AUTOMATICALLY SWITCH ON WHEN THE GRID FAILS?
Yes. Bonnen HESS will automatically switch to the battery when the grid fails.
HOW LONG DO BATTERIES LAST? The lithium-ion batteries range from 4000 to 6000 cycles (charges/ discharges of the battery) at 80 per cent discharge rate, meaning an expected life of more than 10 years for high-performing systems (if cycled once per day). Bonnen LiFePO4 design life is over 15 years.
WHAT IS THE TOTAL INSTALLED COST OF THE HOME ENERGY STORAGE SYSTEM VERSUS THE EXPECTED OUTPUT OVER ITS LIFETIME?
Now we based on the current market level to count it for reference. Assume that the system is composed of 5kW inverter and 10kWh energy storage battery, and the selling price of the system is the inverter, battery, components and installation cost A total of 66000 yuan ≈ 10000 euros. Assuming that only 10kWh/day is considered for self-use and Internet access is not considered, 4 euros of electricity will be saved every day (we take average grid electricity at 0.4 euros/kwh), and the payback period will be 6-9 Years. If the subsidy factor is considered, the investment cycle can be further shortened to 2-3 years.
