300Ah lithium storage for a compatible 24V system
Li-7.5e is a 25.6V lithium iron phosphate battery for home solar storage and essential-load backup. Its 300Ah capacity suits a matched 24V-class inverter system, whether you are installing new storage or replacing a battery.
Not for 48V inverters. Li-7.5e cannot directly replace a 51.2V battery such as Li-5 or PGEM.
Battery communication and monitoring
CAN and RS485 provide communication with a compatible inverter. The inverter must support the battery’s voltage range, current limits and communication protocol; matching nominal voltage alone is not enough.
Built-in Wi-Fi and Bluetooth support configuration and monitoring. They do not replace the inverter-to-BMS connection.
Storage capacity is not output power
The 7.5kWh-class energy rating describes stored energy. Maximum continuous charge and discharge current is 140A; available AC power also depends on the inverter, battery voltage, BMS limits and losses.
Indoor installation and a five-year warranty
The IP20 battery weighs 55.67kg. Allow for suitable mounting support, ventilation and service access in a dry indoor location.
Li-7.5e carries a 5-year warranty, subject to written terms. The rated cycle life is at least 6,000 cycles at 25 degrees C, 90% depth of discharge and 0.5C; actual life depends on operating conditions.
Model-specific IEC 62619:2022 and EMC documents are available below.

Frequently asked questions
Is Li-7.5e a 24V or 48V battery?
Its rated voltage is 25.6V, making it a 24V-class battery. It is not a direct replacement for a 51.2V battery and must not be connected to a 48V inverter.
What information do you need to check compatibility?
Send the inverter make, full model and a clear equipment-label photo. For a replacement, include the existing battery model so the charging settings and communication requirements can also be reviewed.
How long will it power my home?
Divide usable battery energy by the average connected load to estimate backup hours, allowing for reserve settings and inverter losses. Use an appliance list to estimate demand; the nameplate storage capacity is not all available as AC energy.
Check Li-7.5e for your system
Send your location, inverter make and full model, and required backup hours. Let us know whether this is a new installation or a battery replacement.
