Nominal and usable battery capacity

These ALP 5.0L-E2 US packages use Growatt's published capacity ratings, not a 95% estimate. The 5kWh, 10kWh and similar option names identify the package class; exact energy is shown below.

Modules	Nominal energy (kWh)	Manufacturer-stated usable energy (kWh)
1	5.12	4.6
2	10.24	9.2
3	15.36	13.8
4	20.48	18.4
5	25.60	23.0
6	30.72	27.6
7	35.84	32.2
8	40.96	36.8

Usable energy is the battery rating before inverter losses; actual delivered energy depends on operating conditions and system settings. Source: Growatt ALP LV-US datasheet, December 2024.
