OVERVIEW
The Redback system has a storage capacity of up to 28.4kWh
using one or two BE14000 enclosures. Each enclosure holds
up to four batteries and a second enclosure is always required
for five or more batteries. Batteries are connected in parallel.
The allowable battery combinations and resultant storage
capacities are shown below (in kWh).

@ 2.4kWh each
Usable capacity is typically 90% of total capacity Battery installations must include a minimum of two batteries per cabinet of any listed model
Insufficient space in enclosure for this combination.
Pylontech batteries use an integrated Battery Management System (BMS) to manage ultimate charge and discharge rates
(protecting the batteries from heat damage) and to inform the Smart Hybrid System of status. The BMS also protects the
batteries from total discharge, assisting system reliability and longevity.
Batteries are identified as Master, 2, 3, 4 etc up to 8. This refers to the position of individual batteries in the BMS chain of
command, where the first connected battery is the Master.
The battery identity may also indicate the physical position of the battery within the enclosure, as indicated in section 3.14.4.

Batteries are named and positioned as shown in
A minimum of two batteries per cabinet is required.
The Newest-is-Master rule also applies when adding batteries to an existing system.
To ensure even cooling, batteries must be installed in the approximate positions shown. They must not touch the
rear or sides of the enclosure, or each other.
Batteries are unrestrained on the enclosure shelves, held in place by their own mass.
Batteries must be independently earthed to the enclosure as shown in
