In this video a quick update on the ALFFAA 1500 watt inverter. Recently I found out it can't power my Wagner Furno 500 Heat Gun. amzn.to/3T6RY92 It starts for a few seconds then quits an error light and beeping occur.

Good information
My guess: the heat gun presents a non-resistive load, maybe using something like a pulse width modulated internal system to manage its heat output. The little inverter can't handle what it sees as an oddball power factor.
Try simultaneously running the heat gun and a resistive load. That might give you some more insight.
Thanks, I will give it a try. I've used a couple different battery chargers and an 800W shop vac with it, and they worked fine.
That is an odd problem. I wonder if maybe there is too much in-rush current before the heating elements heat up and the resistance goes up?
Don't come through idaho we got snow as usual. L, o, l, it'll be gone by the time you get here
We are still down near Ajo, The weather has been quite nice, but gonna leave soon before it starts to get too hot for boondocking, and maybe move up along the Virgin River in southern Nevada for a spell. :)
I’d be really interested to hear what the ALlFAA manufacturer says, please let us know if they respond to your video. Thanks Ray.
Could it be a open ground or neutral ground issue in the heat gun? When you were transferring energy from one battery to the other; do you have any idea of the loss incurred due to using this Inverter. I have a real small inverter (600W) that I have not used for that purpose but I have considering it. For now I just transfer the battery, but if the loss is minimal, I'll take the lazy way out.
The heat gun is only a two-prong, so there is no ground. It works fine on other inverters.
The losses were quite high, roughly 30% I'd guestimate with the DC-AC-DC conversions happening. I usually do it only if there has been limited solar energy for many days and my main RV batteries are getting very run down. A DC-DC charger may be a better way to go, will have to experiment one day with one. :)
@@LoveYourRV I assumed the loss would be high. My wag was going to be 20-25%. (DC-AC-DC). Well I'll look forward to the answer on the heat gun.... TNX
The inverter loss isn't too bad, maybe 10% but battery chargers are terrible as far as efficiency goes. I guess because they rightly expect to have grid power as an input. :)
