The following table describes approximately how much the voltage may vary depending on the
temperature of the batteries.
Inverter Condition
Temperature on BTS
Charger Operation
Charger Mode
BTS ≥ 50°C(122°F)
Automatically turns off charger
BTS ≤ 40°C(104°F)
Automatically turns on charger
Inverter Mode
40°C(104°F) ≤ BTS ≤
50°C(122°F)
Increases the low voltage shut
down point by 0.5Vdc
BTS ≥ 50°C(122°F)
Over Temp Fault
A Battery Temperature Sensor
has been provided as a
separate accessory. It comes
with 15’/5M cable.
Important:
If the battery temperature is allowed to fall to extremely cold temperatures, the invert-
er with a BTS may not be able to properly recharge cold batteries due to maximum voltage limits
of the inverter. Ensure the batteries are protected from extreme temperatures. For more detailed
technical information, please contact us.

. Other Features
20A DC output
When there is ignition signal on Pin 1 or when
the inverter transfers to qualified AC input, the
Pin 3 will output 12Vdc 20A DC power

Low Battery Voltage Recovery Start
After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model),
the inverter is able to restore to work after the battery voltage recovers to 13V/26V/52V(with pow-
er switch still in “On” position). This function helps to save the users extra labor to reactivate the
inverter when the low battery voltage returns to acceptable range in renewable energy systems.
