(SPH4000TL3 BH up to and including SPH10000TL3 BH and Growatt SPA4000TL3 BH - SPA10000TL3 BH) Warranty: 10-year Growatt warranty (see warranty document in Downloads) Installation We always recommend that you consult an authorized electrician when connecting your battery to ensure a safe and legal installation. The Growatt High Voltage battery ARK-2.5H-A1 2.56 kWh is supplied fully charged by Growatt. If several batteries are subsequently connected, it can take up to 14-90 days until the battery pack is fully balanced and may only then be fully discharged. The length of time depends on the number of charging cycles of the existing batteries. The battery may only be connected when room temperature has been reached. The battery has a protection class of IP65 and can be mounted on a wall or on the floor. Installation on the floor requires a separate base. The battery is 65 cm wide, 26 cm deep, 18 cm high and weighs 30 kg. The battery module can only be operated in conjunction with a battery management system.

The Growatt ARK 2.5H-A1 high-voltage battery (MPN ARK-2.5H-A1) is a LiFePO4 storage system with high cycle stability and a long service life. The modular, stackable concept enables flexible application for different scenarios and is easy to install. The battery offers excellent performance under high loads and is also suitable for outdoor installation with its IP65 protection. The soft start is used to prevent overvoltage in the system. About the ARK 2.5H-A1 battery: Modular, stackable battery concept Cobalt-free lithium iron phosphate (LFP) High cycle stability and long service life Wall or floor installation possible Soft start to protect the system from overvoltage Automatic wake-up in the event of undervoltage IP65 protection class for outdoor installation Remote diagnosis and firmware update The ARK battery system Thanks to its modular concept, the ARK system can be used flexibly and expanded as required. A battery tower can be installed with at least 2 and up to 10 storage modules; several towers can also be installed in one system. One BMS control element and a connection cable set to the corresponding inverter are required per tower for operation. One battery base per tower is also required for ground installation. The ARK high-voltage storage systems are compatible with the MIN and MOD-XH, as well as the three-phase SPH and SPA inverters. Depending on the inverter series, a different control unit, a different connection cable set and a different starting number of batteries are required. The ARK-XH system starts with 2 batteries, while the ARK-HV system starts with 3 batteries. Areas of application For grid-connected and stand-alone photovoltaic systems Emergency power supply Uninterruptible power supplies (UPS) Flexible expansion The ARK battery system from Growatt offers a high degree of flexibility thanks to its expandable configuration options, which range from 5.12 kWh to 25.6 kWh. Installation and expansion of the system is simple and straightforward thanks to the modular design and the use of cables. Another innovation of the ARK system is that, unlike other battery systems, no battery cabinet is required. Only a battery base is required for a stable stand. Soft start to protect the system The soft start mechanism is a protective function that is used with the Growatt battery to protect the system from overvoltage. When the battery is started or switched on, the power supply is gradually increased to protect the system from damage that could be caused by a sudden voltage spike. This ensures smooth and safe operation of the battery system. Long cycle life The Growatt ARK battery modules are an ideal storage solution for photovoltaic systems due to their extremely long cycle life and the use of LiFePo4 cells. Regardless of whether it is a grid-connected or off-grid system, the Growatt storage system offers numerous advantages compared to conventional lead batteries and other lithium technologies.
