Vroom Power — Three Paths for the Same Sun
Vroom Power · Direct Solar Intelligence

Same sun. Four very different paths.

Drag the sun across the sky. Watch how much of its power survives the trip to your outlets — and how each system decides what to do with it.

01 — TODAY, MOST COMMON

Grid‑tied solar

Panels feed an inverter, which syncs to the grid. The grid absorbs whatever the sun sends — loads run at fixed rates whether the sun is blazing or barely out.

lost in conversion
No storage. Excess solar exports to the grid — and when the sun drops, the grid seamlessly takes over and feeds the loads instead.
No coordination. Thermostat and water heater run on fixed schedules — they don't know the sun is out.
02 — OFF-GRID, NO UTILITY TIE

Off-grid solar

Panels charge a battery bank through a charge controller, then an inverter turns stored DC into usable AC. No grid at all — if the battery runs dry, the loads go dark.

lost in conversion
Three conversions. Charge controller, battery, inverter — every step before the power is usable.
No backstop. There's no grid to lean on. Every load depends entirely on what's left in the battery.
03 — HYBRID: SOLAR + BATTERY + GRID

Hybrid solar

A hybrid inverter sits at the center — splitting power between a battery bank and a distribution box that ties to both the grid and your loads. Every path still runs through at least one full conversion.

lost in conversion
Battery and grid, both optional paths. The hybrid inverter decides where power goes moment to moment.
Grid is the backstop. When solar and battery both fall short, the grid quietly picks up the loads.
04 — DIRECT SOLAR INTELLIGENCE

DSI — power that thinks

DSI delivers stable AC straight from the panel to the load — no battery, no grid interconnection. Smart loads talk back over a live wireless link, so consumption adjusts to what the sun is actually doing. Solar power only ever goes to loads — never out to the grid.

lost in conversion
One step by day. Panel to load, stabilized at the source — nothing to charge, discharge, or export.
Grid steps in after dark. A backup tie feeds straight into DSI so smart loads stay powered overnight — DSI still never buffers or stores anything itself.
