I have just bought and installed a CTEK D250S Dual for my Rapido. I chose CTEK over Sterling precisely BECAUSE it is 20 amp rather than 40 amp. This means I can use existing wiring, making installation a great deal simpler. Agreed, it won't charge as fast as the Sterling, but on the other hand, I have bought it and installed it - if I had waited until I was ready to install the cables and stuff required for the Sterling it would NEVER get fitted.
I had hoped to use th MPPT solar panel controller element of it, but the CBE control panel and distribution box has an ignition controlled relay, disconnecting the input when the ignition is off, so I have reverted to the original SP controller. I could connect differently to allow the MPPT solar panel controller to operate, but then I would lose the ammeter on the cbe control panel
I'll try to remember to let you know how it goes in practice
