Hi Kirk You didn’t give a lot of info but I don’t think there is a product that meets your requirements.
I’m guessing its either 24v or 48v system with with a C40 controller. Personally I’d leave the old system as 20 year old modules are not cost effectively worth messing with. And if you did, you’d get what a couple hundred watts more at max maybe? And then use the CC that best fits your system for the 5kw new. 100 amp, midnite or OB or Schneider My 2 cents Jay > On Jun 1, 2022, at 3:31 PM, Kirk Herander via RE-wrenches > <[email protected]> wrote: > > > All, > I have an off-grid customer adding more PV to their 20 yr old array.
