How energy storage works Growatt AXE 50.0H-1HR-E1 ×2
The manufacturer's instructions describe the system's operation directly: at night, without sun, the battery AXE supplies the load via an inverter (PCS); during the day, energy from the panels takes priority, and any surplus is charged to the storage. Chain of 20 modules AXE 5.0H-E1 EU (each 16 cells 100 Ah in 1P16S, 51,2 V system) supervised by the control module AXE 1000100-C1, which measures SOC, system voltage, current, and cell voltages and temperatures and communicates with the inverter via CAN/RS485.
In practice, the energy storage increases the self-consumption of photovoltaic energy: instead of feeding surplus energy into the grid at a low price and buying it back at a higher price in the evening, you consume your own energy when you need it. Combined with a hybrid inverter, the energy storage also provides emergency power to key circuits during a grid outage.
Who is this energy storage for?
- Companies and plants with PV installations — the energy storage shifts surpluses from midday to afternoon and evening working hours, increasing self-consumption.
- Customers with a power tariff or peak demand — Discharging at 1C allows you to cut peaks (peak shaving) and avoid charges for exceeding the contractual power.
- Facilities requiring emergency power supply — with hybrid inverter WIT the system supports selected circuits in the event of a power outage.
- Installations expanded in stages — subsequent cabinets are connected in parallel.
Selection for this capacity: 20 modules in a 2-cluster configuration AXE 50.0H-1HR-E1; ×2 configurations give full power with any inverter WIT 29.9–50K-XHU (system document).
The most important features
- Charging and discharging 1C — power in kW equal to capacity in kWh (card note: limits inverter).
- 19-inch rack — modules 482×131×580 mm each ≤47 kg, replacement and service from the front.
- Up to 4 clusters in parallel — expansion without replacing equipment (WIT 50–100K-HU, busbar box).
- Cobalt-free LiFePO4 cells — 6000 cycles (0,5C, 25 ±2 °C, 60% EOL), DoD 90%, RTE above 95%.
- IP20, air-cooled — technical room, -10–50 °C.
Compatible inverters and accessories
Growatt AXE 50.0H-1HR-E1 ×2 is a high-voltage (HV) energy storage device designed to work with: three-phase hybrid inverters Growatt WIT 29.9–50K-XHU and WIT 50–100K-HUThe control module is selected for the system AXE 1000100-C1. Warning: The battery voltage class (LV/HV) must be compatible with the inverter - we will confirm the selection before purchase. You can find the full range of inverters at inverter categories.
Construction of a rack system
Growatt AXE 50.0H-1HR-E1 ×2 to rack-mount energy storage system with a capacity of 100 kWh in a multi-cluster system: total 20× battery module AXE 5.0H-E1 EU After 5 kWh (51,2 V) in 19-inch racks, each with its own control module AXE 1000100-C1 (high voltage BMS, CAN / RS485 / USB communication). Manufacturer's system documentation for inverters WIT XHU predicts clusters AXE 30.0–60.0H-1HR-E1 connected in parallel (×2 = 61,44–122,88 kWh, ×3 = 92,16–184,32 kWh); this system is 2 clusters AXE 50.0H-1HR-E1 (2 cabinets, each with its own control module).
Each cluster operates at a current of 1C = 100 A, at a temperature of -10–50 °C, with air cooling and IP20 protection class (technical room). Dimensions: 2 cabinets 570×1964×660 mm; total weight up to 1180 kg (sum of the cabinet weights from the data sheet). The module has 5 kWh in the commercial designation, and nominally 100 Ah × 51,2 V = 5,12 kWh — hence in the system document the cluster capacities are given as a multiple of 5,12 kWh.
Selection of energy storage capacity
Rack system: modules AXE 5.0H-E1 EU after 5 kWh connected in series in the cabinet (3–16 modules = 15–80 kWh according to the manufacturer's instructions), and cabinets connected in parallel - system documentation WIT XHU+ AXE gives variants ×2 (61,44–122,88 kWh) and ×3 (92,16–184,32 kWh). We select the capacity based on daily energy consumption and the investment purpose: to increase self-consumption, an energy storage system covering evening consumption is usually sufficient, while for real emergency power, larger capacity and power are selected. Contact info@pvgroup.pl – we will calculate the right size for your installation and inverter.
Growatt AXE 50.0H-1HR-E1 ×2 and savings and self-consumption
In net billing, energy fed into the grid is priced lower than the energy you later buy back. Energy Storage Growatt AXE 50.0H-1HR-E1 ×2 This balance is reversed: surplus panels, which would otherwise be fed into the grid at a low price, are stored at your home and used in the evenings and nights. This increases self-consumption, reduces electricity bills, and significantly shortens the return on investment in photovoltaics. Furthermore, there's a value that's difficult to quantify in złoty: energy security: in the event of a grid outage, the energy storage unit, along with the hybrid inverter, maintains power to the facility's most important circuits. The higher energy prices and the greater daily consumption, the faster the energy storage unit pays for itself. Therefore, when selecting a system, we consider your actual consumption profile, not just the system's power output.
parameters Growatt AXE 50.0H-1HR-E1 ×2 in practice
A 6000-cycle lifespan (25 ±2°C, 0,5C, 60% EOL) means many years of operation with daily charge-discharge cycles. A DoD of 90% and round-trip efficiency of >95% allow for virtually full utilization of rated capacity. LiFePO4 (LFP, cobalt-free) cells are thermally safe and resistant to degradation.
Design: IP20 protection class, operation in the temperature range of -10–50 °C with air cooling and noise below 60 dB, 2 cabinets 570×1964×660 mm with a total weight of up to 1180 kg - installation on a level floor, transport and setup require heavy-duty equipment.
Safety - LiFePO4 cells
Growatt AXE 50.0H-1HR-E1 ×2 built on lithium iron phosphate (LiFePO4) cells. This is the safest chemistry commonly used in commercial and industrial energy storage today: it is thermally resistant, cobalt-free, and much less susceptible to thermal runaway than older NMC cells. A built-in battery management system (BMS) continuously monitors individual cell voltages, temperatures, and charge and discharge currents, disconnecting the energy storage device in the event of an abnormality and balancing the cells for longer life. Combined with long cyclic durability, this translates into years of maintenance-free operation of the energy storage device.
Installation and operation
Growatt AXE 50.0H-1HR-E1 ×2 must be installed by a qualified installer in accordance with the manufacturer's instructions. The IP20 protection rating determines the installation location; pay attention to the operating temperature range and ventilation. The energy storage is managed by BMS and inverter - after starting, its status (SOC, charging, discharging) can be seen remotely in the application ShinePhoneThe device is covered by a European service warranty (5 years, optional 10 years according to the manufacturer); we issue a Polish VAT invoice with the order.
