How can solar charge a home battery, according to DOE?

Directly over DC or after conversion to AC.

  1. Only after being converted to gas
  2. Only through the neighbor's meter
  3. Directly over DC or after conversion to AC ✔

Why: Some systems send panel DC straight to the battery. Others convert it to AC first. The inverter setup decides which path is used.

Huh, didn't know that: DOE says string and microinverter systems can both be paired with a system that controls how solar works with battery storage.

The dad joke
Why did the sun take a break? It needed to recharge its solar batteries.

    Both types of inverters might be assisted by a system that controls how the solar system interacts with attached battery storage.
