Suggested Battery Bank Capacity
Note:
this is a guide only. It is the responsibility of the installer to ensure the correct battery bank is installed.
·Simple calculation of battery discharge time
：
Battery capacity / discharge current = discharge time
eg
：
12V/220V/50Hz/300W full load of inverter100% Efficiency 89%
Discharge time is 1 hour. What is the optional battery capacity?
·Select the battery size according to the following formula
：
⑴
300W÷89%=337W Output power/efficiency = input power
⑵
337W÷10.5V=32A Input power / battery voltage (lowest operating Voltage) = Input Current
⑶
32A×1hour=32AH Input current × discharge time = battery capacity
⑷
a 40Ah battery can be discharged in 85 minutes.
Note: (Actual discharge time error may exist according to the lifespan and mantainenece of the battery.)
Ventilation and Positioning
(Note: There should be no obstruction within 15cm of the ventilating holes.)
Mounting Suggestion:
Output and Load
CAUTION
Input Derating Curve
Output Derating Curve
The unit should be mounted on a flat surface or holding rack with suitable strenth. In order to ensure the lifespan of
the unit, please refrain from operating in environment of high dust, high temperature or high moisture. This is a
power supply with built-in DC fan. Please make sure that ventilation is not blocked.
install in a horizontal position using the mounting points provided. Install in a dust & moisture free area.
The inverter can power most loads that need an AC source which need to be powered continuously. This applies to
light loads such as phone chargers and light loads. It is not reccomended to run heavy loads continuously.
(1) Since inductive loads or motor based appliances need a large start up current (6~10 times the rated current), the
inverter may not start up successfully with these kinds of loads. Induction cookers cannont be used on these
inverters for this reason.
(2) When using capacitive or switched loads(such as a power supply), to ensure proper operation, only turn on the
load or increase the load after the unit has been turned on. Do not start the inverter with the load on.
A battery bank that is of larger capacity than needed should be installed. (to meet the discharge time and load
requirements) The time that a load can run for is NOT determined by the inverter, rather than by battery capacity.
