Microinverters, Explained - A Plain-English Guide
Last verified: September 2026
One small inverter under each panel, so every panel works on its own. Here's why that's wonderful for shade — and the trade-offs to weigh. Questions? My number is (330) 200-8042.
Microinverters, at a Glance
Microinverters put a small inverter under each panel, so every panel converts its own power right on the roof. Because each works independently, a shaded or weak panel doesn't drag down the others, and you can watch each panel on the app. The trade-offs are a higher up-front cost and roof-mounted service. Like all grid-tied inverters, they shut off in an outage unless you add a battery. This guide explains it all plainly. There's a printable 29-page version up top.
Common Questions
1 How do microinverters work?
Each panel gets its own small inverter mounted behind it, converting that panel's DC to AC right on the roof. The panels no longer depend on one another, so each works independently.
2 Why are microinverters good for shade?
Because each panel converts its own power, a shaded panel only affects itself — the rest keep producing at full strength. There's no shared string to drag down, unlike a plain string inverter.
3 Do microinverters give power during an outage?
No, not on their own. Like every grid-tied inverter, they shut off in an outage for safety. You need a compatible battery and backup equipment to keep chosen circuits running.
4 What are the downsides of microinverters?
They usually cost more (a device per panel), and since each lives on the roof, servicing one means roof access. The upside is that a single failure affects only one panel, not the whole system.
5 Do microinverters have good warranties?
Often yes — frequently among the longest in solar, sometimes close to the panel warranty. Terms vary by maker, so read the actual warranty and check whether roof-access labor is covered. See our warranties guide.
6 Are microinverters always better than a string inverter?
No — they're better for shaded or complex roofs. A big, open, sunny roof may do just as well with a string inverter for less. The right choice depends on your roof.
Would You Rather I Just Help?
Considering microinverters, or already have them? I'll help you understand whether they fit your roof, what the warranty really covers, and how to read the panel-by-panel monitoring — in plain English, with nothing to sell you. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
