Hybrid vs Grid-Tie vs Off-Grid: Which Inverter Topology Fits Your Project?
A practical comparison of the three inverter topologies for solar projects — what each does, what they cost, and how to choose the right one for your market.
Choosing the inverter topology is the first and most consequential decision in any solar project. This guide compares the three mainstream topologies and maps them to real project scenarios we see from B2B buyers.
Quick comparison
| Grid-tie | Off-grid | Hybrid | |
|---|---|---|---|
| Exports to grid | Yes | No | Configurable |
| Battery support | No | Yes | Yes |
| Works during outage | No | Yes | Yes (< 10 ms) |
| Typical use | Bill reduction | No grid available | Storage + backup |
| Relative cost | Lowest | Medium | Highest |
Grid-tie: maximize ROI on an existing grid
Grid-tie inverters convert DC to AC and export surplus power to the grid. They are the cheapest per watt and the most efficient, but regulations require them to shut down during outages — no backup power.
Best for: markets with net metering or feed-in tariffs, and customers whose goal is purely economic.
Off-grid: power where the grid doesn’t reach
Off-grid inverters form their own mini-grid from PV and battery, often with a generator input as backup. Sizing discipline matters: you must cover the worst month, not the average one.
Best for: rural electrification, telecom sites, islands and cabins.
Hybrid: the fast-growing middle ground
Hybrid inverters combine a grid-tie inverter with a battery charger. They export when it pays, charge when it’s cheap, and back up the home when the grid fails — all in one unit.
Best for: markets with rising blackout frequency, time-of-use tariffs or self-consumption incentives. This is the fastest-growing segment in most regions we serve.
