Our Iraqi customer wanted to replace the 48V 50Ah lead-acid batteries installed in their telecom base station to build a more efficient 20kWh energy storage system. Based on their requirements, we suggested a solution consisting of two 48V 200Ah rack-mounted solar batteries to be used in parallel to satisfy the energy demand. Rack-mounted lithium batteries contribute to more efficient power storage, are simple to install and maintain, and take up little space inside the telecom base station. After carefully weighing the advantages of our suggestion, the customer swiftly accepted this lithium battery solution.
