Most AC motors have a large spin up surge current that can be 4 to 6 times the run current that has a time duration of about half a second. It is also very inductive during startup meaning the peak sinewave current lags the peak sinewave voltage by close to 90 degrees phase shift. This causes a very poor power factor (0.2 to 0.4) during startup.
The inductive reactance causes the motor to draw more peak current. Part of peak current is inductively stored during part of the sinewave cycle and given back up to AC supply source during other part of sinewave cycle. This is a reverse power flow back to AC source during a portion of the AC cycle.
HF inverters don't like poor power factor, reactive loads that spits back power during a portion of the sinewave. It causes feedback control stability issues on battery to HV DC converter. They typically start to have problems with stability for an inductive load power factor less than 0.75.
LF inverters' large, heavy, low frequency transformers can support overload current with low power factor, inductive loads, better. LF inverters are inherently bi-directional capable in power flow and just pushes the partial sinewave cycle inductive return current back to batteries. (Yes, there can be charging battery current push back for a portion of AC cycle). The inherent, instant bi-directional power flow change capability also make LF inverters much better choice for AC coupling of PV GT inverters.
HF inverters may specify a peak surge current but say nothing about allowable time duration or spec something like 1 to 10 milliseconds. Such short surge duration time allowance is fairly useless for starting up an AC motor.
SolArk and Deye have a large bank of HV DC storage capacitor that helps supply surge current and keep battery to HV DC converter stable at a lower load power factor, but still unable to support very low power factor, high current, loads less than 0.5 to 0.6.
