Hybrid Inverters: When One Box Should Run Solar AND Batteries
When you want solar and serious storage working as one system, a hybrid inverter is often the cleanest answer.

A hybrid inverter combines a solar inverter and a battery inverter in one unit, managing panels, storage and the grid together. That integration is what makes deep backup and off-grid setups work smoothly.
What a hybrid does well
- Whole-home backup: a hybrid can carry your whole panel through an outage, not just a few circuits.
- Battery flexibility: many hybrids are battery-agnostic and expandable, so you can add capacity later.
- Generator integration: units like Sol-Ark can auto-start a standby generator when the battery runs low — true layered resilience.
- Off-grid and grid-hybrid modes: the same box can run grid-tied, grid-hybrid or fully off-grid.
The platforms we use
For hybrid and off-grid builds, iSolar works with Sol-Ark and EG4 — robust, expandable inverters that pair with stackable LFP batteries like HomeGrid. For a more modular, microinverter-based approach, Enphase solar-plus-storage is the alternative. The right choice depends on whether you want whole-home backup, off-grid capability, or simple essential-load resilience.
When a hybrid isn’t needed
If you only want solar savings (no backup), a standard microinverter or string setup is simpler and cheaper. Hybrids earn their keep when storage is central to the plan.
Frequently asked.
Sol-Ark or Enphase?
Sol-Ark/EG4 hybrids excel at whole-home and off-grid backup with large, expandable battery banks. Enphase is modular and great for essential-load backup tied to a microinverter array. We match the platform to your goal.
Can a hybrid run my whole house off-grid?
Yes, with enough solar, battery and often a generator. See our off-grid solar page.
