That is why I run my critical stuff (servers + timekeeping) of batteries. When I designed the setup, I calculated that I got 15 *times* the hold-over for the same money. And yes, put a MorningStart Sunsaver MPPT and a couple of panels on your battery, and you get close to "permanent" hold-over, unless you live in Denmark.
