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.

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 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 high 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.

Hybrid inverter

In contrast to conventional inverters, hybrid inverters offer the option of not only feeding the solar power generated into the grid, but also storing it in batteries. This means that the stored solar power can be used even when the sun is not shining. Another function of hybrid inverters is to optimize a household's electricity consumption by preferring to use the solar power generated directly in the household before it is fed into the grid. This leads to a reduction in energy costs and less dependence on expensive grid electricity.

Operating modes - configurable according to system requirements

Online mode: Different operating modes can be set for optimum system integration of the sph inverter. When entered directly on the device, a priority mode can only be set for one time period. When using the online platform, up to three time periods can be set for the priority mode (a chargeable accessory is required to use this function).

• Load first:With the standard "Load first" mode, the connected loads (consumers) are supplied with energy first. As soon as the PV energy is sufficient for the load, the surplus energy is fed into the battery. If the battery is fully charged or none is connected, the remaining energy is fed into the grid.
• Battery first:In this mode, the inverter first fully charges the battery with the maximum possible solar power. If the PV power is not sufficient, the grid charging function can also be activated.
• Grid first:In this mode, the PV energy generated is fed into the grid first. The on and off time of the mode can be set here, as well as the power rate.

Backup mode: If there is no longer any mains voltage at the device, e.g. due to a short-term power failure or blackout, the Growatt sph automatically switches to backup mode. This ensures that the AC output is supplied via the EPS-LOAD connection. The required energy is only supplied via the Solarasystem and the battery. If the PV system also fails, the battery secures the AC supply until it is discharged. If required, the automatic switch to this mode can also be deactivated.

Maximum Power Point Tracking

By using Maximum Power Point Tracking (mppt) technology, a Solarasystem can achieve the optimum yield. The MIC inverter is equipped with mppt, which adjusts the optimum ratio of voltage and current throughout the day according to the solar radiation and the module temperature of the solar modules. With its wide mppt voltage range, many solar modules can be connected, enabling efficient energy generation. This advantage is particularly evident when the sky is partly cloudy and the light intensity is constantly changing.

Intelligent load management

The inverter's integrated smart load control enables precise and efficient control of energy consumption. By using a potential-free contact, electrical loads can be controlled intelligently and prioritized. This function enables automatic detection of energy requirements and optimum use of the available energy. Smart load management ensures optimum distribution of energy and thus contributes to efficient use. With intelligent load control via the dry contact, the inverter is able to optimize the energy flow and ensure efficient operation of your Solarasystem.
