Yes, simple solutions also work fine if you are prepared to do the installation work that goes with it. There is a case to be made regarding installing a DC power distribution network in our homes these days. Just about every extra outside of cooking, water heating and refrigeration now runs on DC 12V. The argument goes that why do all these increasingly complicated power conversions for backup purposes?
Solar (DC) , charges a battery DC, drives an inverter AC, distributes power to devices which have a myriad of power packs which convert AC back to DC again? Just distribute DC from your battery packs straight to the DC devices.
