An offset system is sized by how much daytime consumption it can displace — air conditioning, water heating, well pump, pool equipment, EV charging. Those loads run when the sun is up, which is why offset systems return money every single day while a backup bank sits idle waiting for a storm. This kit is built for the first job, and excess production exports to the utility where net metering allows.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFlexBOSS21: 16kW max AC output with PV and grid · 12kW battery-only · 21kW max PV input · 66.7A max continuous output\u003c\/li\u003e\n\u003cli\u003eGridBOSS MID: 200A entrance rating · NEMA 3R\u003c\/li\u003e\n\u003cli\u003eThree inverter slots plus a generator port · maximum current per port 125A \/ 80A \/ 60A \/ 60A\u003c\/li\u003e\n\u003cli\u003ePeimar 450W Mono PERC: 20.82% efficiency · Voc 41.18V · Isc 13.85A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCheck Your Utility First\u003c\/h2\u003e\u003cp\u003eSell-back economics vary enormously. Full retail net metering makes export as valuable as consumption; an avoided-cost tariff pays a fraction of retail and pushes you toward self-consumption and storage instead. Get your utility's current rate structure before finalizing the array size — it changes the correct system, not just the payback math.\u003c\/p\u003e\u003ch2\u003eRoom To Expand\u003c\/h2\u003e\u003cp\u003eThree inverter slots on the GridBOSS and a dedicated generator port. Add panels now, storage later, a generator after the first long outage — the interconnection hardware absorbs all three without being replaced.
