I'm exploring the possibility of installing a hybrid inverter system (like the GridBoss/Flex Boss combo) with around 2,400 watts of solar panels and batteries for backup power. I'd love to go fully DIY, but I'm not too confident with some parts of the installation yet, so I've been looking for quotes for partial or full installation help. However, I've been told that Minnesota laws require interconnection if I want to install any PV panels while still connected to the grid. Since my power output will be low, I'd prefer to avoid the complications of interconnection and just cycle the solar through my setup locally. Is it legal to do this in Minnesota? Does anyone have experience working with contractors who are okay with hybrid systems that support DIY efforts?

If you're unclear about certain installation aspects, just ask! There’s tons of info available, and many folks here could share their experiences. YouTube is also a great resource for learning the details.
As someone who installs systems, I’d suggest always getting a second opinion from different contractors. Some might push for full service just to maximize their profit. Just remember, as long as you’re not back-feeding into the grid, you're typically fine. If you need to bring in an electrician for any grid connections, that can save you a lot of money. Plus, I’ve got a promo code for equipment if you need it!
Yes, it is legal to have an off-grid system in Minnesota! As long as you don’t interconnect your system, you won’t need to deal with utility regulations. I’ve got a FlexBoss setup too and love it. If you connect the GridBoss to the utility, that’s when you’re interconnecting, but using it off-grid works just fine. So, if you want to keep it local and independent, go for it! If you’re looking for contractors, just be clear with them about your DIY involvement, as many resist working with partial installations.
Got it! Just to confirm, if I use a hybrid setup that's connected to the grid, I *have* to have an interconnection agreement, regardless of how I manage the power?
Exactly! Connecting to the grid essentially means you need an agreement, either way.
