MPPT is by far the most efficient regulator type for getting the max out of your solar, plus the benefits of being able to program for specific batteries. It's making the correct choice with regards to your engine battery support issues. We've always stuck with Victron, as we feel they are a cracking product and the Victron Connect APP really does help in not only keeping the firmware up to date on the regulator, but solar efficiency can easily be read on your device.That's true - however since I put the dual charger in 3 years ago I've not had a problem with starting after storage.
Am I on wrong track with going MPPT?
As we are not fans of dual charge regulators, we always include our Battery Master as part of our solar installations anyway so that deals with the engine battery support. Plus with the added efficiency of MPPT and some sort of engine battery supporting device, I recon you will see the benefits of moving over to MPPT. Also bear in mind that if you go with LiFePO4 Batteries at a later date, it's advised to change the regulator to MPPT with a Lithium Profile.
