EcoFlow Delta 3 Plus Upgrade — Why We Switched Off the Jackery Track

Original plan: Renogy 600W solar (2×300W panels) into a Jackery Explorer 1000 Pro. On paper, plenty for a weekend rig.

Then we did the math again.

The Jackery problem

The Explorer 1000 Pro caps solar input at 400W. That means our 600W of panel would be permanently throttled to 400W — 200W of paid-for capacity just… gone. Not on cloudy days. Every day.

On a two-panel install, 400W might be fine. On a full-length Astro roof with room for real panels, it's leaving trips on the table.

Why EcoFlow Delta 3 Plus

• 1,024 Wh LFP (LiFePO₄) battery — safer chemistry than the older NMC packs, longer life, better cold performance.
• Solar input up to 500W on single MPPT, more with dual-input models — no permanent throttle.
• Fast AC recharge — 0–80% in under an hour if we need to top up from shore power.
• Modular — expansion battery can go on later without buying a whole new unit.
• App — real-time watt-hours in and out, temperatures, cycle count.

Real numbers, first trip

• Fridge cycling on a warm day: ~450 Wh over 24 hours
• Phones, headlamps, laptop top-ups: ~150 Wh/day
• 300W solar output at midday, well within input spec
• Bank stayed above 60% state-of-charge over three days without shore power

What it doesn't replace

A proper permanent house battery + DC-DC + inverter setup is still the "right" long-term answer for a full-time rig. For a weekender that has to also be a work van during the week, a modular unit like this wins on flexibility.
