    FAQs About Energy Storage System from Bonnen Battery

    You need more than just a single lithium battery. You need a veteran manufacturer who has been in the field for 10+ years to save your project time, build your brand and grow your profits. Let Bonnen Battery help you achieve business success.

    Bonnen is an expert in lithium battery manufacturer. We have successfully provided all kinds of comprehensive lithium battery solutions to different counties for about 10 years.

    Yes, with more bulk size orders, prices will be cheaper.

    Normally 30 days after payment is received, but it can be negotiated based on order quantity and production schedule.

    In order to maximize the use of solar power, battery storage makes sense. During the evening, the battery can be used to store the electricity that was not used during the day.

    Bonnen lithium solar cells use CATL, Gotion, EVE Lithium A grade lithium iron phosphate (LiFePo4) cells. These cells are designed for up to 15-20 years of use. Various factors determine the battery’s lifespan. Experience shows that Bonnen energy storage battery can assume a service life of over 20 years and more than 6000 charging cycles.

    Storage energy should be selected based on the amount of PV power installed as well as the amount of power consumed. Battery storage energy should:
    Not exceed 1.5 KWH per 1 KW of PV capacity
    Not exceed 1.5 KWH per 1000 KWH/a of electricity consumption
    Be installed only if the PV power exceeds 0.5 KW per 1000 KWH/a of electricity consumption.

    The storage energy of Powerwall battery can be adapted to your energy requirements. Basically, the storage should be large enough to supply a single-family home with solar power from the evening until the next morning. For an average four-person household with an annual energy consumption of about 5,000KWH, a size of 7 KWH is usually sufficient.

    Calculation: 5,000 KWH /365 days= 13.7 KWH per day and about 7 KWH of that for the night.

    If you wish to choose the right storage energy for your household, it is important to determine its electricity demand as accurately as possible. It is recommended that you calculate the average energy consumption of the past five years as a basis for this calculation. Taking into account possible changes is also critical. For example, adding a family room, installing a new heating system, or purchasing an electric car.

    With an Ac-coupled solar power storage system, the DC power generated by the PV modules is converted into AC power through the inverter, which can be directly fed to the load or the grid. Meantime the converted AC power will further convert into DC to store in battery via DC-AC bidirectional converter. It would be again converted to AC when drawn by the load. Certainly this is not optimal due to the higher conversion losses, but these home battery storage systems are completely dependent on the size of the PV system and can be easily retrofitted.

    In a DC system, the DC is stored directly in the batteries and only converted to AC when it is drawn. Since these systems always have an integrated inverter with defined outputs, only a certain PV system can be connected here.

    Home energy storage systems in the low-voltage range have an output voltage of 48V. 48V low-voltage battery storage technology is a very mature and field-proven technology. It operates at the standard voltage levels of system technology. Bonnen offers a wide range of components in the 48V range. The interconnection takes place in parallel and is scalable to high capacities.

    High voltage system means less discharge current, less heating, more power to be conveyed to achieve high efficiency. Due to the increasing power of solar PV panels and the DC voltage of inverters, the current mainstream PV panel power has increased from 300W to 400W to 600W and more, and inverters DC main bus has achieved to 1500V. The required battery voltage range also increased from 160V-600V, so High Voltage Systems are becoming more and more popular.

    A Home Energy Storage battery with an emergency power connection can supply devices with power in the event of a power failure. In this variant, the connection is usually made by manually activating the integrated emergency power connection. The available power is usually limited to 1-phase consumers in the house.

    When the power goes out, backup power can provide consumers with power from the Home Energy Storage batteries. The switchover takes place automatically after approx. 5-20 seconds, usually via a changeover device, and involves additional installation work. The backup power grid can be set up as a 1-phase or 3-phase.
