How energy storage works Growatt AXE 40.0H-1HR-E1
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 8 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: AXE 40.0H-1HR-E1 is 8 modules in a cabinet with a height of 1560 mm and a weight of up to 480 kg, chain voltage 409,6 V, power 1C = 40 kW - full power is provided by WIT 29.9K, 30K, 36K and 40K-XHU; with WIT The 50K-XHU inverter is limited to 40 kW.
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 40.0H-1HR-E1 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 40.0H-1HR-E1 to rack-mount energy storage system with a capacity of 40 kWh (manufacturer code AXE 40.0H-1HR-E1): 8× battery module AXE 5.0H-E1 EU After 5 kWh (51,2 V, ≤47 kg) connected in series in a 19-inch rack and control module AXE 1000100-C1 (included) - high voltage BMS with CAN/RS485/USB communication, monitoring SOC, system voltage, current, cell voltages and temperatures. Nominal string voltage is 409,6 V (operating range 371,2–454,4 V) and nominal power 40 kW at 1C = 100 A - actual charge and discharge power is limited by the connected inverter.
Usable capacity is 36 kWh (DoD 90 %). The module has 5 kWh in the commercial designation, and nominally 100 Ah × 51,2 V = 5,12 kWh — hence in the manufacturer's system document the same cluster is listed as 41,0 kWhThe cabinet has dimensions of 570×1560×660 mm and weighs up to 480 kg; it stands on the floor, air cooling, protection class IP20 (technical room). The manufacturer allows up to 4 clusters in parallel (WIT 50–100K-HU, via busbar box) – capacity and power scale without replacing equipment, for large corporate and industrial installations working with three-phase hybrid inverters Growatt WIT 29.9–50K-XHU and WIT 50–100K-HU.
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 40.0H-1HR-E1 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 40.0H-1HR-E1 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 40.0H-1HR-E1 in practice
A 6000 cycle life (25 ±2 °C, 0,5C, 60% EOL) means many years of operation with daily charge and discharge cycles. A DoD of 90% and round-trip efficiency >95% allow for realistic use of 36 kWh z 40 kWh rated capacity. LiFePO4 cells (LFP, cobalt-free) 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, cabinet 570×1560×660 mm weighing up to 480 kg - installation on a flat floor (floor stand), transport and setup require equipment for moving weights.
Safety - LiFePO4 cells
Growatt AXE 40.0H-1HR-E1 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 40.0H-1HR-E1 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.
