Descrição
Growatt ARK 12.8 kWh – energy storage set
Growatt ARK 12.8 kWh is a ready-made high-voltage (HV) energy storage set (LiFePO4 batteries) with 12.8 kWh of capacity, made up of 5 modules of the ARK 2.5H-A2 type, from the Growatt.tech range. This model is a high-voltage (HV) LiFePO4 energy storage battery. It charges with surplus solar power during the day and releases energy in the evening and during grid outages, working with a three-phase SPH hybrid inverter. The built-in BMS system watches over cell voltages, temperature and cell balance. An energy storage battery is matched to an inverter of the same voltage class — in this case: three-phase Growatt SPH hybrid inverters (TL3 BH-UP).

How the Growatt ARK 12.8 kWh energy storage battery works
Growatt ARK 12.8 kWh is a high-voltage (HV) LiFePO4 energy storage battery. It charges with surplus solar power during the day and releases energy in the evening and during grid outages, working with a three-phase SPH hybrid inverter. The built-in BMS system watches over cell voltages, temperature and cell balance.
Na prática, uma bateria de armazenamento de energia aumenta o autoconsumo da sua energia solar: em vez de exportar o excedente de energia para a rede a um preço baixo e voltar a comprá-la a um preço mais elevado ao fim da tarde, utiliza a sua própria energia quando precisa. Em combinação com um inversor híbrido, a bateria de armazenamento de energia também fornece energia de reserva para circuitos essenciais durante uma falha na rede.
A quem se destina esta bateria de armazenamento de energia
- Proprietários de sistemas fotovoltaicos que maximizam o autoconsumo — uma bateria de armazenamento de energia reduz o tempo de amortização da instalação.
- Residências e empresas com um inversor híbrido da classe de tensão correspondente.
- Qualquer pessoa que necessite de energia de reserva durante interrupções no fornecimento de eletricidade.
- As instalações são ampliadas por fases — pode aumentar a capacidade à medida que as suas necessidades crescem.
Principais características
- Cobalt Free Lithium Iron Phosphate (LiFePO4) cells — safe and durable.
- Cycle life of around 6000+ cycles
- Depth of discharge (DOD) 90% — capacity you can actually use
- BMS integrado — proteção contra tensão e temperatura, além de equilíbrio das células
- Conceção modular — fácil expansão da capacidade
- IP65 ingress protection
Inversores e acessórios compatíveis
Growatt ARK 12.8 kWh is a high-voltage (HV) energy storage battery, designed to work with: three-phase Growatt SPH hybrid inverters (TL3 BH-UP). Battery management relies on the HVC 60050-C2 controller for safe operation. For mounting, the ARK 2.5H-A1 base is used. Note: the voltage class of the battery (LV/HV) must match the inverter — we will confirm the pairing before you order. You will find the full range of inverters in the shop.
O que está incluído no conjunto
Growatt ARK 12.8 kWh is a ready-made energy storage set with 12.8 kWh of capacity, made up of 5× ARK 2.5H-A2 battery module (high-voltage (HV)) together with the accessories needed for commissioning: the HVC 60050-C2 controller plus the ARK 2.5H-A1 base included in the package. The set is prepared to work with three-phase Growatt SPH hybrid inverters (TL3 BH-UP) — the voltage class (HV) and capacity are already matched, so the installer mounts it without selecting components separately. If needed, the capacity can be expanded later with additional modules.
This set in numbers
| Modules in the set | 5 × ARK 2.5H-A2 |
|---|---|
| Nominal capacity | 12.8 kWh (5 × 2.56 kWh) |
| Usable capacity | about 11.5 kWh at the datasheet depth of discharge of 90% |
| Total weight | about 135 kg (5 × 27 kg per module) |
Figures for the complete set are calculated from the per-module values in the manufacturer’s datasheet.
Determinação da capacidade de armazenamento de energia
Modular expansion: 3-10 modules in series form a 7.68-25.6 kWh system — you size the capacity to your needs and add more modules later. Capacity is matched to the daily energy consumption and the goal of the investment: to increase self-consumption, an energy storage battery covering the evening load is usually enough, while real backup power calls for more capacity and power. Write to info@growatt.tech — we will size the system for your installation and inverter.
Growatt ARK 12.8 kWh — savings and self-consumption
In many European markets, depending on your tariff, electricity exported to the grid is worth less than the electricity you later buy back. The Growatt ARK 12.8 kWh energy storage battery reverses that balance: surplus solar energy that would otherwise be exported at a low rate is stored on site and used in the evening and at night. Self-consumption goes up, electricity bills go down, and the payback period of the PV investment gets noticeably shorter. On top of that comes a value that is hard to put a price on — energy security: during a grid outage, the energy storage battery together with a hybrid inverter keeps the most important circuits running in a home or business. The higher the energy prices and the bigger the daily consumption, the faster the energy storage battery pays for itself — which is why sizing should start from the real consumption profile, not just from the installed PV power.
Growatt ARK 12.8 kWh parameters in practice
a cycle life of 6000+ cycles means many years of daily charging and discharging. the high depth of discharge (DOD 90%) lets you use nearly the full capacity in practice. Cobalt Free Lithium Iron Phosphate (LiFePO4) cells are thermally safe and resistant to degradation.
Construction: IP65 ingress protection, operation across a discharge temperature range of -10~50 °C, a weight of 27 kg.
Segurança — Células de LiFePO4
Growatt ARK 12.8 kWh is built on lithium iron phosphate (LiFePO4) cells. This is currently the safest chemistry in common use in residential energy storage: it is thermally resilient, contains no cobalt and is far less prone to thermal runaway than older NMC cells. The built-in battery management system continuously supervises individual cell voltages, temperature and the charge and discharge currents, disconnecting the energy storage battery in case of anomalies and balancing the cells for a longer service life. Combined with the long cycle life, this translates into years of maintenance-free operation of the energy storage system.
Instalação e funcionamento
Growatt ARK 12.8 kWh should be installed by a qualified installer according to the manufacturer’s manual. The IP65 ingress protection rating determines where it can be mounted; pay attention to the operating temperature range and ventilation. The energy storage battery is managed by the BMS and the inverter — once commissioned, its status (SOC, charging, discharging) can be checked remotely in the ShinePhone app. The product is covered by a European service warranty of 10 years, per the manufacturer’s terms.

What sets the series apart — Growatt ARK 12.8 kWh
The ARK 2.5H series is a modular HV battery for three-phase SPH hybrid inverters — you start with 3 modules and expand the system up to 25.6 kWh without replacing any accessories.
What to check when selecting the Growatt ARK 12.8 kWh
The most important thing when buying an energy storage battery is matching the voltage class of the battery to the inverter: this model is high-voltage (HV), so it works with three-phase Growatt SPH hybrid inverters (TL3 BH-UP). A battery of the wrong voltage class will not work. It is also worth planning the target capacity up front (modular expansion is easy, but sizing the system from the start is more convenient) and the installation spot with a suitable temperature range and ventilation. If in doubt, send us your inverter model at info@growatt.tech — we will confirm the pairing before you order.
Monitoring — Growatt ARK 12.8 kWh
You monitor the Growatt ARK 12.8 kWh energy storage battery through the inverter it is connected to: the ShinePhone app and the ShineServer portal show the state of charge (SOC), the charge and discharge power and the operating history, with fault notifications. For installers managing multiple sites, Growatt provides service accounts with a view of the whole fleet from a single panel.
