The \u003cstrong\u003eMultiPlus-II\u003c\/strong\u003e is the newer generation with additional features: built-in grounding relay, current sensor for ESS (energy-storage-system) self-consumption mode, and slightly different external dimensions. For most off-grid, RV, and marine applications, the original MultiPlus is equally capable. For grid-tied ESS (selling solar back to the grid, time-shifting), the MultiPlus-II is the right pick.\u003c\/p\u003e\n\n\u003cp\u003eEvery Jonsson Tech order ships within 5 days nationwide from our Houston, Texas warehouse.
