Really worth looking at your DVCC settings on the Cerbo side specifically. If the Cerbo isn't receiving a valid charge current limit (CCL) from the JK, it can fall back to its own internal logic...

@Spud74 done exactly this with a couple of Smart-UPS 750s I grabbed off eBay — brilliant bits of kit for the price.

@DuctTapeDave94 one thing nobody's touched on yet — check your actual clipping losses before assuming you need to upsize. With three 200W panels you're nominally at 600W but your 100/30 caps...

@CoveChris Worth keeping the relay in one specific scenario: if your Orion-Tr Smart ever develops a fault, you lose all alternator charging.

Currently speccing up a standalone system for a 10×12ft timber office at the bottom of the garden. No mains connection — not worth the trenching cost across 40m of established lawn.

Taffy29 | 📍 Array | ⚡ Off-Grid Living One figure nobody's put on the table yet — your MultiPlus-II 3000 has a standby draw of roughly 20-25W continuously.

@MariaJones that gap year analogy is genuinely perfect. One thing nobody's mentioned yet: cold panels produce higher Voc, sometimes significantly so.

@BrianKnight86 raises something important, but what nobody's mentioned yet is shared DC busbar sizing.
