Just looking for suggestions and recommendations... my misbehaving IG 4000 (it's the third one - 2 were replaced under warranty years ago) is going crazy (see post about power output reduced by 1/3 - now its just stuck in various error modes).
The Primo 3.8 would appear to be the logical plug compatible solution (I'm trying to minimize hassle) but I know at the time Sunny Boy was a big competitor. Goal is to get another 10 years out of the system. The panels have a 25 year warranty and we're at 15 years now so we figure we've got a good 10 years left on the panels and the roof. In 10 years the solar industry will probably look a lot different that it is now (batteries and inverters built into panels?)
I've got 3 strings of 9 Kyocera KC175GT panels (175W, MPV 23.6V, OCV 29.2V, SCC 8.09A, MPC 7.42A). It fits under the specs for the Primo 3.8 and the price is reasonable. The panels are in good shape and produced over 3200W after we reinstalled the panels with new leak-proof mounts a few months ago. Each string is producing roughly the same amount of power so we don't have any dead panels.
We just did a full removal and reinstall of the panels to address a terrible installation job from 15 years ago so PLEASE do not suggest throwing everything out and starting over. The property is a rental and we already dismissed that option.
