*Note:
1.
Test conditions: 100% DOD, 0.2 C charge & discharge @ +25°C.
2.
90% DOD; System usable energy may vary with inverter different setting.
3.
Discharge: In case of battery cell’s temperature range of -20°C~10°C and
45°C~53°C, the discharge current will be reduced; Charge: In case of battery
cell’s temperature range of 0°C~25°C and 45°C~53°C, the charge current will be
reduced. Product charge or discharge power depends on the actual temperature
of battery pack.
4.
The battery can only be discharged and cannot be charged at the range of
from -20°C to 0°C.
5.
In case of a rated current of 30 A, the wire size of 10 AWG for cables (including
grounding cable) is recommended; in case of a rated current of 45 A, the wire
size of 8 AWG for cables (including grounding cable) is recommend.
6.
In the allowable range, the relative humidity range should be between 5%
and 95% RH. In the meantime, effective measures should be taken to prevent
condensation.
