A separate UPS at each point should work if it is online there is no switchover. I found a surge protection unit that you install after the inverter, it picks up surges in nano seconds so it is fast enough, I bought it through Surgetek, part nr 952110. Installed yesterday and the fuse on the AV receiver hasn't blown through 3 switch overs, so far so good. 952110.pdf

Hi Shawn, have you found a solution?

So it seems to be in UPS mode, if you change to APL it is a longer changeover which may prevent the in-rush current which is blowing the fuse, or possibly surge protection may pick it up if you have. Thats what I am hoping on mine when I get my AV receiver back from repairs, if that doesn't work then I don't know what else is possible.

On the unit, follow the user manual to setting nr 13, let me know what setting it was in.

Is your Inverter set in UPS or APL (Appliance) mode?

Hi There, Did you manage to find a solution yet? I have the same issue with the fuse in my AV receiver blowing every now and then on changeover, several people seem to have mentioned it on this form. I have tried a few different surge protection plugs but it seems the changeover is so quick it gets through the plug without blowing it.

Unfortunately no solution yet, changed my AV receiver to a Yamaha thinking it would be less sensitive but unfortunately not. Fuse doesn’t blow every time on changeover. Maybe an on delay timer is possible for the circuit the AV receiver is on. Not getting much assistance from Luxpowertek

Hi There, I have the same issue, have you managed to find a solution?

Hi Shawn, I have the exactly the same issue, Onkyo amp fuse blowing, everything else seems fine, did you find a solution?

Hi Everyone, having trouble with the 5 amp fuse blowing in our Onkyo audio receiver since we installed a Luxpower SNA 500 and Dynes 5.1kwh battery. I am also using a clearline surge protection for high and low voltage plug. I replaced the audio receiver with a Yamaha system and that has also now blown, any suggestions?
