Solar repair. When production drops.
Inverter replacement, microinverter swap, monitoring faults, string voltage drop, panel-level diagnostics. We work on Enphase, SolarEdge, SMA, Fronius, and most pre-2015 string inverters. Most repairs are a single visit.
Daily production tanked? It is fixable.
A solar system that produced 38 kWh on a sunny June day in 2022 should still produce 38 kWh in 2026. If it does not, something is broken — usually one specific thing, and usually fixable on a single visit. Most installers will not service systems they did not install. We do.
The four most common solar failures we see in East Tennessee: (1) a string inverter that has aged out and needs replacement at the 10-12 year mark, (2) a failed microinverter on one or two panels showing up as zero production on the monitoring app, (3) a tripped DC disconnect or AGI from a lightning event, and (4) monitoring system disconnected from the home Wi-Fi after a router replacement.
We start with the monitoring data. Enphase Enlighten, SolarEdge mySolarEdge, SMA Sunny Portal, and Fronius Solar.Web all log per-panel or per-string production going back years. Comparing this week against the same week three years ago narrows the cause to a specific panel, inverter, breaker, or interconnect before we put a ladder on the roof.
For inverters past warranty, we quote replacement with a same-brand drop-in or a brand-agnostic alternative. For microinverter swaps, we replace only the failed unit unless we’re seeing pattern failures across the same vintage. Most single-issue repairs are a half-day or a day on site.

Solar repairs we see weekly.
Monitoring data diagnosis
We pull your historical production data first. Enphase, SolarEdge, SMA, Fronius — the platform tells us which panel, inverter, or string is the issue before we climb anything.
String inverter replacement
Most string inverters age out at 10-12 years. We do same-brand drop-in replacements (SolarEdge HD-Wave for SolarEdge, SMA Sunny Boy for SMA) or brand-agnostic alternatives if your platform is being discontinued.
Microinverter swap
Enphase microinverter replacement, single-panel or batch. We swap the bad unit, re-register on Enlighten, and verify production by panel before leaving.
Monitoring reconnection
Wi-Fi changes, router swaps, and ISP changes routinely disconnect solar monitoring. We get you reconnected to Enlighten, mySolarEdge, etc., and verify the data flow.
DC disconnect + AGI diagnostics
Lightning, GFCI faults, and worn DC disconnects all show up as system shutoff. We trace the path from panels through combiner to inverter, find the open, and restore production.
Out-of-business installer rescue
Bought a system from an installer who is no longer operating? We pick it up. Most modern hardware is interoperable enough to service even when the original company is gone.

Text or call us first
Describe the job. We follow up with a phone chat to scope it, then we send your quote. Same-day for most residential.
On-site walk-through
For larger jobs, we come out, look at the panel, and talk through what you actually want. Free. No “let me get back to you.”
Itemized estimate
Every line item priced. Materials, labor, permit, inspection. You see exactly where the dollars go before you sign anything.
Job day · permits handled
We pull permits, coordinate with the county inspector, and arrive when we said we would. We protect your floors. We label every breaker. We test every circuit before we leave.
Inspection & sign-off
Inspector signs off, we walk you through what changed, we hand over the documentation. If anything ever flickers, you have our cell.
Our SolarEdge inverter died at year 11. The original installer closed down years ago. Volt Pro pulled the historical data, confirmed the inverter, and had a replacement in and producing two days later. Most installers refused to even quote it.
Five things we get asked every week.
My solar production dropped — what could it be?
My original solar installer is out of business — can you still service it?
How much does a solar inverter replacement cost?
Is my solar warranty still good?
Can you reconnect my solar monitoring after I changed routers?
Production down? Let us check.
