"Bright Sword" - three "swordsmen" of energy storage officially unveiled

Release Date:April 07, 2023 Visits:18 Source:

  Recently, Runda Photovoltaic Energy Storage POWER HOUSE series battery packs officially appeared in Runda Photovoltaic Yancheng Jianhu Production Center, which are 3U low-voltage battery packs (left), energy storage all-in-one machine (middle) and high-voltage battery packs (right ).

  The 3u battery pack is currently a pack of 5 kilowatt-hours, supporting 16 units in parallel. With overcharge protection, over discharge protection, charge overcurrent, discharge overcurrent protection, high and low temperature protection, short circuit protection and other functions;

  The current battery of the all-in-one machine is 10 kilowatt-hours. Compared with 3u, there are more inverters. The inverter supports grid-connected mode and off-grid mode. When the power grid is abnormal, the system will automatically switch to off-grid mode, and the system will supply power to the load through batteries and solar energy. In the grid-connected mode, the user can set 3 modes: load priority, battery priority, and grid priority. If not set, the default is load priority. Load priority means that the photovoltaic energy will be given priority to the load. When the photovoltaic energy cannot meet the load demand, the battery will start to discharge. When the photovoltaics fully meet the load demand, the excess power will be stored in the battery, and if there is no battery or the battery is fully charged, the excess power will be incorporated into the grid. Battery priority means that the system will give priority to charging the battery. Grid priority means that when the system works in this mode, the power generated by photovoltaics will be connected to the grid first. Users can choose different modes for self-use, shaving peaks and filling valleys.

  The high-voltage battery pack currently supports 2-5 battery packs in series. One battery pack is 5 kWh, and can be stacked up to 25 kWh. Users can choose according to their needs. The high-voltage pack is composed of a high-voltage box and a battery pack. The high-voltage box has total current measurement, total voltage measurement, insulation detection, etc., and the battery functions are roughly the same. The main difference lies in the detection of voltage, current and temperature, overcharge protection, overdischarge protection, charge overcurrent, discharge overcurrent protection, high and low temperature protection, etc. The stacked structure design of the high voltage battery pack is also more convenient.
