Description
Growatt ALP 5.0L – energy storage battery 5 kWh
Growatt ALP 5.0L is a low-voltage (LV) energy storage battery (LiFePO4 cells) with a capacity of 5 kWh from the Growatt.tech range. This model is a low-voltage (LV, 51.2 V) LiFePO4 energy storage battery. It stores surplus solar power and releases it whenever the installation would otherwise draw from the grid, increasing self-consumption. The integrated BMS with CAN communication looks after the safety and service life of the cells. An energy storage battery is matched to an inverter of the same voltage class — in this case: Growatt inverters that support low-voltage batteries (LV, 51.2 V).
This page gathers the complete information about the model: how it works, compatible inverters, expansion options, the full specification from the manufacturer’s datasheet and capacity sizing. All parameters come from official Growatt documentation — we list them to make selection easier and to avoid mistakes at purchase. If questions remain after reading, our technical team will help match the energy storage battery to your inverter, the capacity to your energy use and the remaining components of the PV installation — write to info@growatt.tech.
Expert commentary
“The Growatt ALP 5.0L is a solid low-voltage (LV) LiFePO4 energy storage battery, which we recommend for extending a PV installation with higher self-consumption and backup power.

How the Growatt ALP 5.0L energy storage battery works
Growatt ALP 5.0L is a low-voltage (LV, 51.2 V) LiFePO4 energy storage battery. It stores surplus solar power and releases it whenever the installation would otherwise draw from the grid, increasing self-consumption. The integrated BMS with CAN communication looks after the safety and service life of the cells.
In practice, an energy storage battery increases the self-consumption of your solar power: instead of exporting surplus energy to the grid at a low price and buying it back at a higher price in the evening, you use your own energy when you need it. Combined with a hybrid inverter, the energy storage battery also provides backup power for key circuits during a grid outage.
Who this energy storage battery is for
- PV system owners maximising self-consumption — an energy storage battery shortens the payback time of the installation.
- Homes and businesses with a hybrid inverter of the matching voltage class.
- Anyone who needs backup power during interruptions in the electricity supply.
- Installations expanded in stages — you add capacity as your needs grow.
Key features
- Cobalt Free Lithium Iron Phosphate (LFP) cells — safe and durable.
- Depth of discharge (DOD) 92% — capacity you can actually use
- Integrated BMS — voltage and temperature protection plus cell balancing
- Modular design — easy capacity expansion
- IP66 ingress protection
Compatible inverters and accessories
Growatt ALP 5.0L is a low-voltage (LV) energy storage battery, designed to work with: Growatt inverters that support low-voltage batteries (LV, 51.2 V). Battery management relies on the integrated BMS with CAN communication for safe operation. 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.
Sizing the energy storage capacity
Expansion: 5 kWh modules connected in parallel into clusters (up to 40 kWh per cluster) and multiple clusters — capacity grows with your needs. 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 ALP 5.0L — 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 ALP 5.0L 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 ALP 5.0L parameters in practice
the high depth of discharge (DOD 92%) lets you use nearly the full capacity in practice. Cobalt Free Lithium Iron Phosphate (LFP) cells are thermally safe and resistant to degradation.
Construction: IP66 ingress protection, operation across a discharge temperature range of -10°C~50°C, a weight of 44 kg at 690/185/295 mm in size.
Safety — LiFePO4 cells
Growatt ALP 5.0L 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.
Installation and operation
Growatt ALP 5.0L should be installed by a qualified installer according to the manufacturer’s manual. The IP66 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 ALP 5.0L
The ALP series is a modern modular LV energy storage battery with a high IP66 protection rating — easy to expand in parallel.
What to check when selecting the Growatt ALP 5.0L
The most important thing when buying an energy storage battery is matching the voltage class of the battery to the inverter: this model is low-voltage (LV), so it works with Growatt inverters that support low-voltage batteries (LV, 51.2 V). 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.
