Benn,
I recently addressed a similar issue on this list in regard to an old SW4024 that showed a visible arc when the generator was disconnected, and the general response was that the arcing didn't represent a failure, that it was fairly routine. Ask him when he sees the spark. When the unit sees ac, it waits about 30 seconds, latches and then ramps up to its maximum current setting. If it doesn't latch or ramp up a control or relay board is likely bad. The DR is repairable, and some shops, such as Inverter Service Co., a part of Direct Power in Albuquerque, can repair it, but with shipping it's not worth fixing unless it's all he can afford. The repair will cost more than a working DR is worth, but still likely less than any new replacement. Certainly there are far better inverters available. But the fact that the customer has continued to use the DR suggests that (a) he is probably satisfied with it otherwise, and (b) is on a tight budget. Therefore my advice would be to make sure there's a breaker on the AC input (this won't prevent the arcing but will allow shutoff in case of failure, and set aside the money to replace the DR if it fails. It may last for years like this. Allan Allan Sindelar A

Wrenches, An off-gridded (system installed by others) called me yesterday with a concern.His system is older and has had mods added over the years. It is up to 7x Siemens SP75 and 1x She'll SQ80P. I believe the inverter is the original. It is a Trace DR2412, and where the concern stems from. He says he has noticed an arc from inside the inverter about 3 of the last 8 times he has fired up his generator (remote start next to inverter). He described seeing the arc thru the vent fins on the top right of the inverter. Is this internal arc typical when a generator connects to the inverter and he just hasn't noticed it before? ...or is his ol Trace toast?
