Hybrid inverter and battery

AC-coupled Battery

Keep your existing inverter

  • Fastest retrofit — add a battery without changing your current solar inverter.
  • Great for newer PV systems that you’re happy with.
  • Flexible placement and sizing; easy to add later capacity.
GoodWe all-in-one hybrid with battery

DC-coupled (Hybrid)

Replace inverter • Connect panels to hybrid

  • Panels connect to a new hybrid inverter + battery for higher round-trip efficiency.
  • Simpler wiring & monitoring; better daytime charging behavior.
  • Ideal if your existing inverter is aging or out of warranty.
Sungrow hybrid inverter and battery pack

Full System Upgrade

New panels + hybrid inverter + battery

  • Solar panels today are nearly 2× as efficient vs 10 years ago, with only marginal size increase.
  • Generate 30–40% more energy on the same roof area — perfect for EVs, larger A/C, electrification, and going gas-free.
  • Clean slate: fresh warranties, modern monitoring, battery-ready from day one.

Quick comparison

Option Best for Pros Considerations
AC-coupled Recent PV systems that you want to keep Fast install; no inverter change; flexible battery sizing Lower round-trip efficiency vs DC; two inverters to manage
DC-coupled (Hybrid) Older/failed inverter; desire for higher efficiency & unified monitoring Better charging efficiency; cleaner wiring; modern app Requires replacing the existing inverter
Full Upgrade Max energy yield, higher future loads (EV, electrification) 30–40% more energy on same roof; new warranties; battery-ready Highest upfront change-out; re-design required

Energy gain figure is typical vs decade-old arrays; actual results vary by model, roof orientation, and shading.

Can I add more battery capacity later?
Yes — most systems allow expansion. Your quote will show compatible add-on options.
Do I need to replace my existing inverter?
No for AC-coupled; yes for DC-coupled (hybrid). We’ll recommend the most cost-effective path based on your system age and goals.
Is the instant estimate a final quote?
It’s a guide based on your inputs. The formal quote follows after photo verification by a human.
