question

If Victron didn't declare a PF in the datasheet, you get what you get. Compliance with the emissions standard should mean it has a relatively high PF...

I would like to think Victron products being in a higher price bracket would provide active PFC on the AC inputs.

Buy, measure and return if not suitable? And let us know!

I have the regular Victron 12V 30A charger and run it successfully on a Honda EX7 which has only 600W continous. I remember the efficiency was as advertised. You are very likely fine.

Got a Blue Power IP67 12/25 charger in the mail today , guessing its the same as the current Bluetooth IP67 chargers ,but can't change to a lower charge rate or monitor the battery voltage with the Blue Power model, was a fair bit cheaper than the Bluetooth model too.

Testing this charger today at full load I'm a bit disappointed with the power factor , was 0.66 , current draw was around 2.25 amps. That was with generator input of 238v AC .

On mains 251v AC the PF was 0.67 and around 2.16 amps input .

Both tests got a maximum 24 amps DC output .

On the box it shows that it is 92% ultra high efficient, that's correct going on true power watts at around 355 to 365w at full load ( what we pay for on mains metered power ) but not so if going by apparent power , which is what matters on generator power., its more like 58% efficient when considering the added reactive power, so the generator is working to load more like 535 watts.

Anyway on the upside I've heard that the inverter generator doesn't suffer poorer fuel efficiency due to the poor power factor of the load ( battery charger) but the output of the generator is down graded due to the higher reactive power and higher current, so the generator trips the overload at lower level than expected.

Also I'm getting about 5 amps DC more output with around 0.1 amps AC less input compared to old my 21 Amp charger , so that's a positive too.

Looks like you need to spend a lot more $$ to get a perfect power factor.......eg the Phoenix models.
