Every roof kit needs an inverter to turn the panels’ DC into the AC your house runs on. The choice that matters is whether it can talk to a battery.
String inverter
Simple, efficient and about $500 cheaper. Perfect if you will never add storage and your roof gets sun on one plane.
Hybrid inverter
Runs the panels and a battery from the same box, with two MPPT inputs for roofs that face two ways. Adding a Keeper battery later is a plug-in job, not a rewire.
Four out of five kits we ship now include the hybrid. Most of those owners added a battery within two years.
