    In modern solar power generation systems, hybrid inverter battery plays a crucial role. They not only store the electricity generated by solar power but also ensure continuous power supply in the home when there is a grid failure. This article will delve into the working principles and operational processes of hybrid inverter battery to help you better understand their functionalities and benefits.


    How Solar Energy is Converted to Electricity


    In solar power generation systems, hybrid inverter battery begins their work with the energy collection of the solar panels. When sunlight strikes the panels, visible light is converted into electricity, and the current then flows into the battery and is stored as direct current (DC). Depending on the type of system, solar panels can be categorized as AC-coupled or DC-coupled. DC-coupled systems usually have built-in inverters, which can convert DC into alternating current (AC), making the generated power usable for household appliances or stored in AC batteries.


    In contrast, DC-coupled system batteries do not have built-in inverters. In this case, the DC from the solar panels flows into the battery via a charging controller, and then the stored power is first converted from DC to AC before being supplied to household devices. By properly configuring hybrid inverter battery, users can maximize the efficiency of solar energy use, thereby enhancing overall system performance.


    Charging Process of Hybrid Inverter Battery


    Hybrid inverter battery has a relatively simple yet efficient charging process. When the electricity generated by the solar panels exceeds household demand, the excess power is stored. For instance, on a sunny afternoon, the battery may quickly become fully charged. When the battery is sufficiently charged, the charging controller will cut off charging to prevent overcharging.


    Additionally, hybrid inverter battery has their unique advantages in power supply. Generally, the energy generated by solar panels is sufficient to meet the power needs of household devices, such as refrigerators, televisions, and lighting. When the battery is adequately charged, the surplus energy can be used to charge the battery, thus storing it for backup. This process ensures that users can rely on the power provided by hybrid inverter battery to maintain daily life even during a grid outage.


    Why Choose Hybrid Inverter Battery?


    There are two main reasons to choose hybrid inverter battery: providing stable power assurance and economic electricity strategies.


    First, hybrid inverter battery can quickly isolate the household system from the grid and activate backup power when a grid failure occurs. This self-protection mechanism can effectively avoid inconvenience caused by power outages.


    Secondly, hybrid inverter battery also supports Time-of-Use (TOU) schemes, which means you can store electricity during periods of low rates and use it during peak periods, thereby reducing electricity costs. By optimizing the timing of electricity use, users can achieve higher economic benefits.

    FAQ

    What solar applications use Anern energy storage systems?

    Anern's energy storage systems are used in the following solar applications:


    Residential Backup Power: 

    For home use during power outages, providing up to 6 hours of continuous power for average household consumption. These systems reduce grid reliance and electricity bills while storing excess solar energy.


    Commercial and Industrial Energy Management: 

    Installed in factories and businesses to store excess solar energy, reduce peak-hour grid consumption, and lower electricity costs. Systems are deployed in secure, ventilated locations for stability.


    Off-Grid Infrastructure: 

    Supports meteorological/hydrological observation equipment and other critical infrastructure in remote areas without grid coverage. Battery banks store solar energy converted via inverters for reliable operation.


    Agricultural Operations: 

    Powers farms by converting stored solar energy into AC electricity, maintaining agricultural activities during outages or grid instability.


    Large-Scale Solar Projects: 

    Used in independent photovoltaic power stations ranging from 10KW to 50MW capacity, enabled by parallel-connected hybrid inverters for solar energy conversion and storage.

    How long is the lead time for the product?

    3-7days for samples, 7-20 days for bulk order, depending on order quantity and production schedule.

    Will the solar lights work all night?

    If you live in a sunny place like South Africa or South America, wholesale solar street lights from Anern can easily last 10 hours at night all year round. In some Northern European countries, solar lights last for a shorter time at night in winter. In these areas, it is expected to last an average of six hours during winter.

    Does Anern supply solar energy storage systems (ESS)?

    Anern supplies integrated solar energy storage systems that combine lithium battery storage with solar inverters and system components for residential, commercial, and off-grid solar power applications.
