Installation method Stacked horizontally onto each other to form a tower with pedestals included, (one per module) or 19 inch rack mounted with brackets (cabinet excluded). Vertical mounting on floor or wall (shelf/bracket) with terminals facing upwards also acceptable. Generally up to 4 x e5000's oer system (for larger capacity requirements, see the Freedom Won LiTE ranges>)
Dimensions when e5000 placed horizontally:
Height x Width x Depth (Front to rear)(mm)
Single unit with pedestal: 247x460x463
Dimensions exclude busbars on front Single unit without pedestal: 247x440x443
Module height equates to 5U (U = Standard 19" rack unit)
DC leads to Inverter or DC bus per positive & negative connection - minimum cable size (mm^2) *cables included - see included accessories 1 X 35mm
Enclosure Steel - painted white, rated for indoor use only, out of direct sun and away from other heat sources.
DC Connection - Integrated Terminals on Front 2 X M6 bolts each for positive and for negative terminals for DC leads to inverter and busbars for connection of parallel e5000's in a tower or rack configuration
Tower interconnecting busbars - minimum cross section area (mm^2) *busbars included-see included accessories

70(17 x 4 mm busbar available in accessories)

*note that the Freedom Won busbar accessories are designed for the pedestal tower dimensions not for 19" rack mounting, which has different spacing.

Communication and Control Interfaces (See manual for further details)

CAN Bus (RJ45 Socket x 1) - for interfacing with compatible inverters and system controllers (the eTower is fullycompatible with all common CAN bus compatible brands).

• RS485 (RJ45 Socket x 1) - for interfacing with the Voltronics Axpert range of inverters equipped with a RS485 lithium battery interface and the applicable firmware.

• RS232 (RJ45 Socket x 1) - for interfacing with a PC for firmware and setting updates (only by Freedom Won technicians).

• RS485 (RJ45 x 2) - for the communication connection of parallel batteries up to four in tower.

• Digital Outputs x 2 - for controlling external relays based on pre-set functions.

Protection Internal electronic protection including overcurrent, cell under and over voltage, temperature out of range, weak cell detection, minimum SOC control, active voltage based charge current limiting. *do not short circuit or connect in reverse polarity!
