Had this exact issue with my 100/30 last spring. Turned out the absorption voltage was set correctly but the absorption time was far too short — Victron's adaptive algorithm calculates it based on...

@PartnerCamper is right, but worth understanding why the discrepancy exists rather than just blindly trusting one over the other. The Daly calculates SOC primarily from cell voltage, which is...

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.
