| Type | What it does | Typical use |
|---|---|---|
| Inverter | Battery → wall outlets | Small, simple setups |
| Inverter-charger | Battery → outlets, and generator/grid → battery | Vans and RVs (shore power), off-grid backup |
| All-in-one inverter | Inverter-charger + solar charge controller in one box | Homes, cabins, tiny houses |
| Hybrid inverter | All-in-one that also works with the grid | Home backup |
Sizing it
The inverter's kW is how much it can run at once, not how much it stores. Add up what could run together, and leave room for big starters like a well pump.
- 120V only (lights, fridge, outlets): a smaller unit like the EG4 6000XP.
- Need 240V (well pump, dryer, big mini-split): the EG4 12000XP.
- Vans: a Victron MultiPlus-II.
