SAJ BU3-5.0-TV2-PRO-BASE is a 5 kWh high-voltage lithium iron phosphate battery module with an integrated base, designed for SAJ HS3 all-in-one systems. It is used as the bottom or base module of the battery stack.
The integrated DC/DC optimiser enables independent control of each module and makes it possible to expand the system at a later date. The quick plug-in connection simplifies battery-stack assembly and reduces visible cabling.
