Re: [RE-wrenches] Outback vfx 3648 question

2023-01-04 Thread Steve Higgins via RE-wrenches 
Hey Jay.

The AC input Amps should be the "Total" Amperage the inverter uses for
pass-thru and charging.   Having the AC In at five and the Charger at five
may be what is causing the pulsing.   Something else to consider the
charging output of the inverter is not monitored very closely so there is a
chance of sugaring/pulsing, but usually, 20-30 seconds is the most you can
see it fluctuate.   I have seen this in the field myself as well.

So if the Generator has a max peak of 10 amps output, I would set up the AC
input at 8 to 9 amps and the charging amps to 4-5.

Re: [RE-wrenches] Outback vfx 3648 question

2023-01-04 Thread Jay via RE-wrenches 
Hi john

Good to hear from you. 

Your system charges at above Outback programmed amp setpoints? 
And in a sort of cyclical way?  Sometimes it’s normal for an hour then will go 
to 2x charge rate then back down then maybe 1.5. 

I talked to a senior Outback tech and they haven’t heard of this issue. 

But if you say is true, how do you adjust the settings so it won’t trip the 
generator breaker?

This one is already at 5aac on ac input and 5 aac on charge and it will still, 
not often trip the generator breaker. 

Thx
Jay

Jay,
 I have seen this a few times but usually with a generator that is not
designed for hard wired system.  I have a Ryobi
work generator that does this on both of my outback systems.  It says
in the instructions that it is not to be used for stationary
applications (ie normally grounded systems).

I have a customer who’s older vfx will do the following 

Settings are 5 amps ac, 5 amp ac  charge 

It’ll run at about 10 amps dc charging
Then randomly go up to 30 amps dc then back down. Maybe 15 seconds
Later go up to 25 amps and back down. Kinda all over the place 

Then will stay at the lower amps for some period of time. 

I’m thinking it’s a hardware problem?

And given the age a new board set is probably in order.

Wrenches, Jay
You may want to remove the battery temp sensor and see what it does, an
open/short in the sensor will send it all over to compensate for the range
issue, the issue may also be in the temp compensation board inside the
inverter.

[RE-wrenches] Outback vfx 3648 question

2023-01-03 Thread Jay via RE-wrenches 
Has anyone had a vfx sort of not pay attention to it charging current settings,

I have a customer who’s older vfx will do the following 

Settings are 5 amps ac, 5 amp ac  charge 

It’ll run at about 10 amps dc charging
Then randomly go up to 30 amps dc then back down. Maybe 15 seconds
Later go up to 25 amps and back down. Kinda all over the place 

Then will stay at the lower amps for some period of time. 

I’m thinking it’s a hardware problem?

And given the age a new board set is probably in order. 

Thoughts?
