The 15.36kWh MUST 51.2V 300Ah LiFePO₄ Lithium Battery provides substantial energy storage for solar and backup power systems requiring a larger battery reserve. With 15.36kWh of energy capacity, it is particularly suited to installations where smaller batteries may not provide sufficient stored energy for the required loads or backup duration.
Its combination of 51.2V nominal voltage and 300Ah capacity makes it suitable for compatible higher-capacity inverter systems serving larger homes, offices and businesses. The increased storage capacity can retain more available solar energy for evening use and periods when solar generation is reduced or unavailable.
The battery uses LiFePO₄ (lithium iron phosphate) chemistry and can form the storage component of a professionally sized solar-plus-battery system. It is particularly useful where the objective is to increase solar self-use, provide essential-load backup or maintain a larger energy reserve.
Actual backup duration depends on the connected load, inverter efficiency and system operating limits. The battery, inverter and solar array should therefore be sized together according to the site’s energy requirements.

Mini FAQ
Q1: How much energy does this MUST battery store?
The battery provides 15.36kWh of energy storage with a capacity of 300Ah.
Q2: What voltage does the battery operate at?
It has a nominal voltage of 51.2V and should be paired with compatible inverter and charging equipment.
Q3: Why choose the 15.36kWh battery instead of a 5.12kWh or 10.24kWh battery?
Its larger storage capacity provides a greater energy reserve, making it more appropriate where the loads, daily consumption or required backup duration exceed what a smaller battery can support.
Q4: Can it store solar energy for use at night?
Yes. In a correctly designed system, available daytime solar generation can be stored for later use when PV production decreases.
Q5: Is this battery suitable for a larger home?
Yes, where a load and energy assessment confirms that the 15.36kWh capacity is appropriate for the home’s required loads and backup duration.
Q6: Can it be used for a business or office?
It can be used in appropriately sized commercial and office solar-storage systems where the inverter and electrical loads are compatible.
Q7: How long will 15.36kWh provide backup power?
There is no fixed runtime. Backup duration depends on the connected load, inverter efficiency and battery operating limits. A professional load assessment provides a more useful runtime estimate.
Q8: Can it work with any inverter?
No. Compatibility with the battery’s 51.2V electrical platform and LiFePO₄ chemistry should be confirmed before installation.
