Electrical - Battery Isolators
Marine battery isolators
Battery isolators and combiners for boats that haven't upgraded to a full lithium platform yet — diode isolators and voltage-sensing relays (VSR / ACR) that allow simultaneous charging of multiple banks from a single alternator without paralleling them.
- Victron Argo diode battery isolators — Schottky diode-based, 80A to 200A
- Victron Cyrix battery combiners — voltage-sensing relays for AGM and lead-acid systems
- OEM replacement isolators
Note: traditional diode isolators and ACR combiners are appropriate for lead-acid systems. For lithium house bank installs, we use isolated DC-DC chargers instead. For complete electrical refit service, see our lithium battery installation page. Marine Electric Systems serves Annapolis, Baltimore, and the Washington DC area.
