Inverter and battery charger basics
Combined inverter/chargers on yachts — AC from batteries, charge profiles, and shore-power transfer.
Overview
An inverter/charger converts 12/24 V DC to 230 V AC for household loads and charges batteries from shore or generator when connected. Units like Victron MultiPlus dominate Nordic refits.
Modes
| Mode | Role |
|---|---|
| Charger | Bulk → absorption → float per battery chemistry |
| Inverter | Supplies AC from house bank — mind Ah budget |
| Transfer switch | Passes shore AC through when connected |
Setup tips
- Match charge profile to AGM vs lithium — see AGM vs lithium
- Size inverter for peak load (kettle + charger often exceeds small units)
- Cable sizing on DC side critical — voltage drop causes early low-battery cut-out
