A South Dakota homeowner said a heavily equipped solar setup still generated 6.1 megawatt-hours in August, even with exports to the grid capped at 22 kilowatts. The same owner also said an earlier set of inverters failed in less than two months, and the issue was traced to the GridBOSS.
Here's what to know
According to a post on r/solar, the South Dakota installation includes 42 kW of solar, two EG4 FlexBOSS inverters, and 60 kWh of batteries, with total inverter output to the grid capped at 22kw.
The original poster wrote, "My first set of inverters didn't last two months, and it turned out to be the GridBOSS being the issue."
Despite that setback, the owner said the array still performed well in poor weather, adding that "on a very rainy and cloudy day I was able to produce over 50kw."

More background
Even with exports capped at 22 kW, the poster said the array and battery setup generated 6.1 MWh in August. Storage capacity and overall system sizing can affect how much electricity a home uses directly and how much gets pushed back to the grid.
Battery-backed solar can give households more flexibility when weather shifts or grid conditions worsen. In this case, the original poster reports producing 50 kW during inclement weather, suggesting the system still delivered meaningful output under less-than-perfect conditions.

EnergySage's solar map also shows the average cost of a home solar panel system by state, along with state-specific solar panel incentives; together, these resources can help homeowners get the best price for rooftop solar panels and access available incentives.
Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save money on energy, and go off-grid. It can also help households manage output more strategically, much like this setup did with 60 kWh in storage and a 22 kW limit on grid exports. Homeowners can explore EnergySage for information about home battery storage options, including competitive installation estimates.
The owner indicated the export cap might not be permanent: "I may increase or even unthrottle at some point."
