Parameters
 In normal mode, the mains frequency is synchronous with the
bypass input frequency.

In battery mode, the frequency is 50 Hz or 60 Hz (tolerance
± 0.05%).
THDv ≤ 1% at rated input voltage and 100% linear load

THDv ≤ 4% at rated input voltage and 100% non-linear load

1
 0 ms (uninterruptible transfer)
≤ 20 ms (interruptible transfer)

Voltage unbalance: ± 3%; phase unbalance: 120± 2°
Inverter overload capability:
100% < load ≤ 110%: transfer to bypass mode after 60 min

110% < load ≤ 125%: transfer to bypass mode after 10 min

125% < load ≤ 150%: transfer to bypass mode after 1 min

 Load > 150%: transfer to bypass mode after 200 ms
Bypass overload capability:
At 30°C, load ≤ 135%: long-time operation

At 40°C, load ≤ 125%: long-time operation

 load > 1000% : run for 100 ms
