High-Capacity 24V Battery Storage
The battery operates at a nominal 25.6V with a rated capacity of 325Ah, providing 8.32kWh of nominal energy storage.
This makes it suitable for compatible 24V-class inverter systems requiring greater storage capacity without using several smaller batteries.
Battery Performance
The technical specifications state:
Operating voltage range: 21.6V to 29.2V
Recommended charge voltage: 28V
Maximum charge voltage: 29.2V
Maximum continuous charge current: 150A
Recommended discharge voltage: 23.2V
Maximum discharging voltage: 21.6V
Maximum continuous discharge current: 150A
Peak discharge current: 200A for 100ms
Expandable Battery System
Up to 16 compatible batteries can be connected in parallel.
Based on the stated 8.32kWh capacity per battery, this allows a maximum nominal storage capacity of approximately 133.12kWh when all 16 units are used.
Series connection is not permitted.
Integrated Battery Management
The battery includes a built-in BMS to assist with monitoring and safe battery operation.
The datasheet also specifies:
Internal resistance: Less than 25mΩ
Round-trip efficiency: Greater than 95%
Self-discharge: Less than 3% per month
Touch Display and Optional Bluetooth
The unit includes a touch display for local battery monitoring.
Bluetooth APP functionality is listed as optional, providing an additional monitoring option where the required functionality is included.

Important Compatibility Notice
This battery is designed for compatible 24V-class inverter systems.
The inverter’s battery voltage range, charging settings, current limits and communication requirements must be confirmed before installation.
Series connection is not permitted according to the supplied datasheet.
Warranty and Installation Requirements
Product warranty: 5 years
All inverters and batteries must be installed by a qualified electrical wireman or Master electrician with a valid registration with the Department of Labour
A valid electrical certificate of compliance (COC) must be issued once installed, specific to the installation of the backup or solar system
The installation must be compliant with SANS 10142 and all its parts
Any warranty claim submitted without installation photos, a valid COC and proof of a qualified wireman or master electrician installing the unit, can be rejected and will render the warranty claim null and void.

Bateries are working good and was delivered as promissed on time to western cape rural area. Thank you.
The staff is very professional and very knowledgeable about their products. The purchase was easy and very quick. I purchased a Lithium battery for my 3 head camera and it's been on ever since especially when there is no sun. I am very happy with my purchase.
I will always prefer solar step, I have ordered solar and they have arrived quickly and they’re working properly. I will always recommend solar step to everyone and hoping to call again soon
Great service. The product itself is quite fancy with lots of options to select. I am very impressed. Money well spent
I must admit I was very nervous buying online again after a 3 month battle with Solar Butler. But you have restored my faith in online shopping your service was very efficient and dilivery was before the said date. Great job guys.
Working great on my inverter. Will recommend it to anyone that is struggling with the same brand inverter. Fast delivery also
I just want to say your service is very very good and your priceing thank you very much
