From DIYer/RV solar to whole-home backup — EG4’s glow-up explained

At InterSolar Texas 2025, I caught up with John Tostanoski from EG4, and we went deep on where the brand is headed next.
EG4 built its name on making solar accessible – RVs, off-grid cabins, and DIY systems that regular people could actually understand and install.
Now they’re stepping into a much bigger arena:
- FlexBoss 21 whole-home backup inverter (21 kW DC input, 16 kW continuous with PV)
- GridBoss microgrid interconnection device (MID) with smart load shedding and generator support
- New 16 kWh indoor wall-mount LFP battery with auto-addressing and active balancing
- Long-term roadmap to three-phase commercial products
- A domestic content battery built with LG cells made in Michigan and assembled in Commerce, Texas
- Future 100V architecture for better charge/discharge performance and smaller cabling
We talk about:
- How EG4 evolved from a house brand at Signature Solar to a full OEM
- Why domestic content matters for third-party ownership and financing
- What pro installers need to know about EG4’s ecosystem
- How you can scale FlexBoss, GridBoss, and multiple batteries within code limits
- Why 48V isn’t going away anytime soon, even as 100V systems emerge
Suppose you’re a solar installer, designer, distributor, or advanced DIYer thinking about whole-home backup or domestic content requirements. In that case, this episode will give you a clear picture of where EG4 is heading.
