    In today’s world, where sustainability and self-sufficiency are becoming increasingly important, off-grid living has gained significant popularity. Off grid battery storage systems allow you to store excess energy generated from renewable sources like solar panels or wind turbines. Stay tuned for our upcoming article, where we will be discussing various aspects of off-grid living and renewable energy storage.

    What is off grid battery storage?

    The off grid battery storage system is organically combined with photovoltaic power generation, energy storage system and inverter to form a single controllable unit. It can directly use photovoltaic components to charge the large capacity battery to meet the demand of electrical load.

    A common off-grid energy storage system is a backup power system (UPS). This system is widely used in areas with frequent power outages, unstable power grids, and areas without power grids, or systems that require high grid power supply guarantee rates.

    Off grid battery storage is mainly suitable for some special and electrical loads far away from the grid. There is still a large market demand for some communication, border checkpoints, islands or field operations and people.

    Why does an off grid system need energy storage?

    Since the off-grid system of renewable energy does not have the backing of the power grid, it is easy to be affected by the environment and cause fluctuations, which will affect the equipment in the system.

    • The time of power generation and consumption is not synchronized, so store it first and use it later.

    Renewable energy systems, especially distributed photovoltaic power stations, have fixed power generation peak hours, but off-grid systems have complex links and different power consumption times. For example, the peak power consumption period of many household off-grid power stations is from 5 to 10 o’clock at night. The peak period of photovoltaic power generation has passed.

    Therefore, only by cooperating with energy storage can we fully utilize the efficiency of renewable energy generation and achieve the purpose of supplementing power consumption of off-grid power stations.Why does an off grid system need energy storage

    • The power generated and used does not match, so it is necessary to store and use at the same time.

    A major feature of new energy power generation is volatility. As the weather changes, the power generation of renewable energy power stations will also fluctuate greatly. In an off-grid situation, there is often no redundant electrical load in the system. If the photovoltaic is directly loaded, the system will be unstable and the voltage will fluctuate, thus damaging the electrical equipment.

    At this time, the energy storage system is a power balancing device. When the photovoltaic power is greater than the load power, the controller sends the excess energy to the battery pack for storage. When the photovoltaic power cannot meet the load needs, the controller sends the battery power to To load, forming a virtuous cycle.

    What should you consider with off grid battery storage?

    Leave enough margin for the inverter

    Usually off-grid photovoltaic power generation is a power supply system for a specific load. During the design process, the rated power of the load connected to the system should be calculated and checked. The output power of the inverter used should be determined based on the total power of the load.

    Consider the surge current, starting power and reactive power required by some special loads when starting, and the impact and demand that reactive power may have on the inverter, and sufficient margin should be left for the inverter.

    Once the energy storage inverter capacity is determined, the capacity of the connected load cannot be expanded or increased at will. Therefore, the off-grid photovoltaic power generation system must leave sufficient margin for the inverter.What should you consider with off grid battery storage

    Fully consider the matching of various loads and inverters

    Off-grid photovoltaic power generation systems must fully consider the matching of various loads and inverters. Especially if there are inductive loads such as washing machines, refrigerators, air conditioners, etc. with motors, sine wave must be selected and equipped. 

    Calculate the average working time and power consumption of each load per day

    The capacity of the photovoltaic array and battery capacity are designed based on customer needs, so as to not only meet the user’s electricity needs, but also control the overall investment cost.

    Off grid battery storage can achieve independent and stable green energy supply. Through reasonable configuration, the efficiency and reliability of new energy power generation can be effectively improved and the dependence on traditional energy sources can be reduced. In practical applications, appropriate configuration solutions and technical points need to be selected according to specific circumstances to meet actual needs.
