A manual disconnect that cuts all power from the battery in one move — for servicing, storage, or an emergency.
One manual disconnect that kills all power from the bank in a single move is essential — for servicing, for winter storage, and for an emergency where you need the system dead now.
It sits in the main positive line between the battery (after the main fuse) and the rest of the system.
Design your van, boat, cabin or RV system in Wattonomy and it places a main disconnect in the battery positive line so the whole system can be isolated in one move — from the appliances you actually run, sized to the recognized standard for your region. You see it on the wiring diagram, in the sized parts list, and in a plain-English build pack that explains the reasoning behind every choice. No account, no email — about a minute to a complete, validated design.
Yes. A manual main disconnect is standard practice and often required — it lets you isolate the bank for service, storage or an emergency.
No. The switch is for manual isolation; the fuse is automatic short-circuit protection. You need both, and the fuse goes first, closest to the battery.
It takes about a minute. No account, no email.
