4. TECHNICAL DESCRIPTION
Operating principle
The principle of operation is based on the conversion of DC current from external batteries into pure
sinewave AC current. The main purpose is to power household and industrial equipment critical to
battery operation mode.
The "autostart" function ensures automatic switching on after power supply. If the input voltage
against low or high voltage is activated.
Recommendations for choosing batteries
Battery storage conditions must meet the requirements of the battery manufacturer.
Notes:
When using a battery of two or more units, they must be of the same type and capacity (if the
batteries have different capacities, they will have different internal resistance, as a result of which
the charge level will be different).
