2.5 Electrical Performance
2.5.1 Invert
Topology
The APV inverter/charger is built according to the following topology.
Invert: Full Bridge Topology.
Charge: Isolate Boost Topology
Because of high efficiency Mosfets and 16bit, 4.9MHZ microprocessor and heavy transformers, it outputs
PURE SINE WAVE AC with an average THD of 15% (min 5%, max 25%) depending of load connected
and battery voltage.
The peak efficiency of APV series is 88%.
Overload Capacity
The APV series inverters have different overload capacities, making it ideal to handle demanding loads.
1 For 110%<Load<125%(±10%), no audible alarm in 14 minutes, beeps 0.5s every 1s in the 15th minute,
and Fault(Turn off) after the 15th minute.
2 For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after the 1 minute.
3 For 300%≧Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.
2.5.2 AC Charger
APV Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The PFC
feature is used to control the amount of power used to charge the batteries in order to obtain a power factor
as close as possible to 1.
Unlike other inverters whose max charging current decreases according to the input AC voltage, APV series
charger is able to output max current as long as input AC voltage is in the range of
164-243VAC(95-127VAC for 120V model), and AC freq is in the range of 48-54Hz(58-64Hz for 60Hz
