For the 52V models the absolute maximum allowable voltage when fully charged is 56V,
however a more typical inverter setting range is 55.5V to 55.8V, depending on the inverter
voltage tracking accuracy in preventing a voltage overshoot above 56V. The voltage
normally used as the minimum cut off is 48V, however this will not typically be reached if
operating down to 90% Depth of Discharge (DoD). The BMS will command the connected
inverter with CAN Bus interface to stop discharging the battery at 10% SoC (90% DoD),
which roughly equates to 49,0V). Under high load the voltage may drop to 48V whilst still
above 10% SoC. A voltage of 48V or even lower can be observed where the standby current
draw on the inverter has caused the battery to be discharged below 10% SoC or below the
48V minimum cut off voltage. The battery breaker will eventually trip the battery at around
47V to protect the cells from undervoltage.
The Commercial HV models typically operate at 512V as this is the ideal operating voltage
for the ATESS HPS hybrid battery inverters (a common pairing). The HV+ models operate at
576V up to 717V depending on the model. This voltage range suits the ATESS PCS battery
inverters and associated PBD DC Charge controllers.
The weight of each model is given in the tables 2.1 and 2.2. The Freedom Lite Commercial
100/70, 120/84 and 140/98 are assembled complete in the Freedom Won factory as
standard. The 160/112 up to the largest 700/490 are either assembled on site by a Freedom
Won site team or, if preferred by the client, can be built into a container at Freedom Won
by the Freedom Won factory team.
The 100/70, 120/84 and 140/98 models require specific lifting equipment to place them into
position. Should a specific site present logistical constraints in relation to placing these
models into position, it is possible to request that Freedom Won assemble the batteries on
site at an additional cost.
The dimensions given in the specification sheets are for the principle outlines of the battery
housing and exclude items that protrude such as the DC cable glands and the circuit breaker
handle.
