Each unit inverts a 48V battery bank to 277 VAC; wire three as a three-phase set and you get a full 277\/480V system rated 36 kW continuous and 75 kW surge. A 200 A adaptive charger, two AC inputs, and an automatic transfer switch are built into one enclosure - so the site gets clean backup, peak-shaving, and generator support without assembling a rack of separate inverters, chargers, and switchgear.\u003c\/p\u003e\n\u003cp\u003eRunning at 48V DC, the Quattro keeps the same field-proven VE.Bus architecture Victron uses across its marine and off-grid line, so paralleling, three-phase coordination, and VRM remote monitoring are built in - there are no third-party controls to integrate. Start with one three-phase set and grow to four (twelve units, 144 kW) as the load does. If your facility is already wired for 277\/480V, this lets you add storage and backup directly on that bus instead of stepping the voltage up or down. \u003cem\u003eIt is a three-phase-only unit - plan on a minimum of three.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eWho the Quattro 15kVA 277V is built for\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial and industrial buildings\u003c\/strong\u003e - battery backup or peak-shaving on a 277\/480V service for warehouses, shops, and light manufacturing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAgriculture and pumping\u003c\/strong\u003e - keep 480V pumps, irrigation, and processing running through outages or off-grid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTelecom and critical loads\u003c\/strong\u003e - sub-20 ms transfer on the primary output keeps controls, IT, and comms online through source changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenerator + grid sites\u003c\/strong\u003e - grid on one AC input, generator on the other, with automatic transfer and PowerAssist.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow the 277\/480V three-phase design works\u003c\/h2\u003e\n\u003cp\u003eEach unit inverts your 48V battery bank to 277 VAC. Wired as a three-phase set of three, the units produce 277V line-to-neutral and 480V line-to-line - the same power your facility's panel, motors, and HVAC already use. Sets are added over VE.Bus and coordinated natively by Victron's System Configurator; no third-party paralleling hardware is required.\u003c\/p\u003e\n\u003ch2\u003eWhy this is the Quattro 15kVA 277V\u003c\/h2\u003e\n\u003ch3\u003eDual AC inputs with an integrated transfer switch\u003c\/h3\u003e\n\u003cp\u003eTwo independent AC inputs (up to 2x 100 A feed-through) with a built-in transfer switch mean no external ATS. A typical site puts grid power on input 1 and a generator on input 2; if the grid drops, the Quattro transfers to the generator automatically, and if neither is present it inverts from battery. Each input has its own configurable current limit.\u003c\/p\u003e\n\u003ch3\u003eTwo AC outputs\u003c\/h3\u003e\n\u003cp\u003eThe main output is no-break and rides through a source loss in under 20 milliseconds - fast enough for controls, IT, and telecom hardware. The auxiliary output is live only when an AC source is present, so non-critical loads can't drain the battery during an outage.\u003c\/p\u003e\n\u003ch3\u003ePowerControl and PowerAssist\u003c\/h3\u003e\n\u003cp\u003ePowerControl caps the current drawn from a generator or service so breakers never trip. PowerAssist supplements a peak load from the battery when demand briefly exceeds the source - so a smaller generator can cover larger transient demands, and the spare capacity recharges the bank once the peak passes.\u003c\/p\u003e\n\u003ch3\u003e200 A adaptive charging\u003c\/h3\u003e\n\u003cp\u003eEach unit charges at up to 200 A (600 A per three-phase set), with an adaptive four-stage profile and an included battery temperature sensor.
