[RE-wrenches] Trace 4024 cutting out

[Dave Angelini Offgrid Solar]

Load test it! It may be the last time. It also might be bad contacts on
the transfer switch. A good tech can switch AC1 and AC2 or may have the
relay.

Chris and Jerry, 

 Sorry, I forgot to mention I did exactly that, had
the Fluke clipped to the + and (-) of the pack and watched it as load was
applied. Yes, voltage fell but never got below ~24.4V when the inverter
output stopped. Checked tightness of all battery connections, terminal to
terminal cables, virtually no corrosion anywhere. Also, inverter stayed ON,
just the output cut-out, then back on then off, then......

bolts going in to the inverter, sounds like low voltage cut out.

 I haven't seen this one
until yesterday. Customer with a 
 20 year old Trace SW4024 called. I've
been servicing this reliable 
 system for the last 8 years. He said after a
delay the power shuts off 
 when a moderate load comes on after 5-15
seconds, then back on, then 
 off..... Light loads no problem, the power
stays on. The inverter 
 stays on the entire time (yellow light and that
famous audio buzz) but I 
 hear a relay? inside the left side of the wiring
section with each 
 change of on-off, off-on state. I assume its a repair
to a service 
 shop. Ideas? Recommendations for repair shops? I haven't
been getting 
 a response from the Solar Cowboyz in Grass Valley.


Thanks,
