[RE-wrenches] Trace Replacement?

[RE Ellison]

I think the reason the older systems lasted so long compared to the newer ones is load control and generally a large battery bank  so they were not cycled to death

I also suspect the newer inverters are not as “tough” for lack of a better description

I have a customer with a rebuilt SW 4024 in the box because he was unsure how the magnum inverters would hold up !

They are now 10 and going strong I guess he can stop worrying now !

Just random thoughts,
Bob ellison

When my clients have limited means and a single SW4024, I install a MS4024 w/conduit box, and leave everything else intact. Often, when dealing with really remote sites, I can have the client send me some pictures of the “power wall” and I can make one trip out showing up with everything I need too make the swap in an few hours. My service truck is stocked for every contingency to do so.

I get calls all the time from folks who have Magnums and ME-ARC controllers……….”How do I get back to %” Plus with the Mate 3, if these get wonky, I can have the client send me pictures of the “Events” so Iknow what were up against. Way more problems with Magnum reliability in the last few years too.

I mean, I have built hundreds and hundreds of SW based systems with modest arrays with a great success rate. Long battery life and minimal equipment failure. Nowadays I feel like Im running around putting out fires and wasting my life on hold waiting for “tech support”. I almost never see ten years with FLA’s.

I have replaced a few over the years and never quite solved the quandary of whether to replace the entire power board, or to retrofit a Magnum/ Outback in place of the SW, and keep the old Trace DC enclosure.  In this particular case, he has a pair of SW 4024s on an old Ananda power center. I'm considering taking the system to 48 v as well, since this will let us use the Magnum 4.4 kW inverters.  This however will also involve rewiring 20 yr old arrays of 50 and 75 watt modules......
>> What is the consensus on the best replacement practices on these legacy systems?  I have several out there with the clock ticking down.  My current idea is to just keep the Ananda and use Magnum's extension boxes to connect up the new MS 4448 inverters.  Its a tough call: I've replaced a few single SW installs and reused the Trace DC enclosure, and cursed working in those tiny boxes.  In other cases, I've put up a whole new system, but wondered if that was over kill too.  It seems to be a case of more field installation hours vs more equipment costs.
