What this means for you

✓ What you can do

  • Plan and buy now; from January 1, 2027 a certified kit of up to 1,200 W plugs in without an interconnection agreement.
  • Use the ordinary interconnection process, or an off-grid portable kit, in the meantime.

✕ Not yet / not allowed

  • Plug in under the new law before January 1, 2027; today the utility interconnection rules still apply.
  • Get paid for exported power under the new law.
  • Assume every kit qualifies: the law requires the certification shown above.

What the rules say

California's SB 868 takes effect January 1, 2027: up to 1,200 W of aggregated AC output per dwelling, certified as a plug-in PV system by UL or an equivalent lab, connected through a receptacle. Utilities may only ask for a simple online registration. The exemption sunsets January 1, 2030, when non-certified plug-in devices also become illegal to sell.

Before you plug in: California checklist

  1. Wait for January 1, 2027. Until then the utility's normal interconnection rules still apply.
  2. Keep the system at or under 1,200 W of inverter output.
  3. Buy a kit whose certification matches the law (UL / NRTL listed). Check the label, not the marketing copy.
  4. Tell your utility: Only if your utility asks. Optional: IOU/POU may require simple online registration (address, make, model, size); no approval.
  5. Renting or in an HOA? The law does not override your lease or covenants, so get written permission first.
  6. Plug into a wall outlet, never an extension cord or power strip, and keep shared-circuit kits under about 400 W.
