FAQ

You can see on our online real-time monitoring cloud platform how much energy is stored and used in total, and how many complete charge and discharge cycles the energy storage system has performed. This can be done through a web browser or an app, which is available for iOS or Android devices. This app allows you to fully monitor the energy flow in your home. So you can easily find out what your solar panels are producing, what your energy consumption is, how much energy your batteries have, and more.

Our energy storage systems are maintenance-free and do not require regular maintenance. Even if a single battery fails or its life decays too quickly (the possibility of this happening is very low), our system will automatically adjust the workload of the battery or even stop it from working. All functionality will continue, with only a slight drop in power storage.

Our energy storage systems can continue to work without the internet, receive software updates via an internet connection when needed, and perform energy monitoring. If the network connection is temporarily interrupted, the energy storage system can continue to operate with its latest settings.

If you have already installed a PV inverter but not an energy storage system, you can connect the output of the original PV inverter to the AC input of the OYSD energy storage system, and then connect your electrical equipment to the storage output of the energy system. Since the input and output voltages of our energy storage system can be flexibly adjusted in the software, it is compatible with almost all PV inverters on the market. The above-mentioned connection installation and software settings need to be wired and installed by professionals to avoid problems caused by installation errors.

Yes, the OYSD energy storage system not only supports the input and output of single-phase AC power, but also supports the input and output of three-phase AC power. When the energy storage system is composed of more than three modules inside, it can be set up and connected to the three-phase grid. The above-mentioned connection installation and software settings need to be wired and installed by professionals to avoid problems caused by installation errors.

Yes, if you have installed a three-phase photovoltaic inverter but not an energy storage system, you can connect the output of the original three-phase photovoltaic inverter to the three-phase AC input of the OYSD energy storage system, and then connect your The three-phase electrical equipment connected to the three-phase output of the energy storage system. Since the input and output voltages of our energy storage system can be flexibly adjusted in the software, it is compatible with almost all photovoltaic inverters on the market. The above-mentioned connection installation and software settings need to be wired and installed by professionals to avoid problems caused by installation errors.

The output power and power consumption of the device will be expressed in kilowatts, and the storage capacity of the battery and the power consumption of the device will be expressed in kWh. The integral of the product of power and time is the power value.

In order to ensure safety and service life, the energy storage system always reserves a certain amount of power to avoid excessive discharge. In the process of charging and discharging, there will be some energy loss. Therefore, judging from the charging and discharging data, the discharged power will be smaller than the charged power.

When mechanisms such as power spot and medium- and long-term transactions with curves are sound, electric energy at different time periods will be priced scientifically and accurately. The main profit model of energy storage projects is "charging during low-price periods, discharging during high-price periods, and obtaining peak-to-valley price differences." Therefore, energy storage investors are very concerned about the level and persistence of the peak-to-valley price difference in the electricity market. Starting from the source and existence conditions of the peak-to-valley price difference, there are two sources for the price difference of electric energy commodities in different periods. First, the supply and demand relationship of electric energy commodities is different in different periods, resulting in different marginal costs of electric energy commodity production. The second is that within several consecutive periods, there are constraints on the adjustment capabilities of power generation and power consumption equipment, and the behavior of power generation and power consumption cannot respond quickly to price signals. Therefore, the energy storage system can take advantage of the peak-to-valley electricity price difference to make a profit. The specific methods include: using the energy storage system to store energy during the low-peak period of electricity consumption to meet the demand during the peak period of electricity consumption. During the peak period of electricity consumption, the stored energy is released, and electricity is exported to the grid to obtain income. In short, the energy storage system can take advantage of the difference in peak and valley electricity prices to make profits, and through a reasonable business model design, it can achieve a win-win situation of efficient energy utilization and economic benefits.

Safety is the most important thing for our energy storage system. We have selected the highly safe lithium iron phosphate battery for our energy storage system, and designed multi-level independent protection functions in the system. At the same time, the system Designed to prevent the spread of thermal runaway, and have a two-stage fire protection system to ensure that it is not flammable even under extreme conditions, so our energy storage system is very safe.
