Couldn't load pickup availability
The Victron Quattro 48/3000/35-50/50 120V VE.Bus is the entry-level 48V Quattro — 3000VA pure sine output (2400W continuous), 35A multi-stage charger, single-phase 120V, dual AC inputs (shore + generator). The right pick for 48V off-grid homes with a backup generator, residential ESS that need automatic source selection, and small commercial backup with utility + generator.
Quattro vs MultiPlus-II — which one?
| Quattro 48/3000 (this model) | MultiPlus-II 48/3000 | |
|---|---|---|
| AC inputs | 2 (shore + generator) | 1 (single source) |
| External transfer switch needed | No — built-in | Yes (if you have 2 sources) |
| Source priority programmable | Yes | N/A |
| ESS / grid-tie capable | Limited | Yes (built-in) |
| Best for | Off-grid with generator backup, dual-source automatic switching | Pure off-grid or grid-tied ESS |
| Price | $1389.75 | $937.55 |
Choose Quattro if: you have both grid/shore AND a backup generator. Saves the cost of a separate transfer switch.
Choose MultiPlus-II if: single AC source, or you specifically want ESS grid-tie mode with self-consumption.
