Solar panels for the Goal Zero Yeti PRO 4000

Written by Ian Schneider·Solar & Off-Grid Tester

Goal Zero gave the Yeti PRO 4000 two solar inputs of very different sizes. The large one is a plug Goal Zero calls HPP+, good for 3000 W at anything from 13.3 to 145 volts. The small one is an 8 mm barrel jack rated for 275 W, and the manual reserves it for a single small panel. Thirty-one of the forty-one panels we track publish an open-circuit voltage, the figure a panel shows with nothing plugged in, and all thirty-one sit under the 145 V line.

Nothing we track fills 3000 W. The biggest set we can build is two of Renogy's 590 W rigid panels in series, plus of one into minus of the next so the voltages stack. That pair delivers 850 W and has the 3994 Wh battery full in a little under five hours of good sun. One 200 W folding panel needs about twenty-eight hours. I'd want a pair of rigid panels on the woodshed roof before I pointed a folding panel at a battery this size.

Nothing in the box connects a panel to it either. Goal Zero's in-the-box list runs to the station, an AC charging cable and the paperwork, and marks the solar input sold separately. The manual says nearly any brand of panel works through Goal Zero's own adapters.

The door

Every panel we track, lined up at the Yeti PRO 4000's solar input

Every panel we track with a published voltage, standing in a line by that voltage. It is the open-circuit voltage, Voc on the back label, what a panel puts out in sun before anything is connected. The black line is 145 V, the ceiling of the HPP+ input. No bar comes close. The Renogy 590 W is the tallest at 52.63 V, and two of them in series still fit under the line.

The 8 mm input has a line of its own, and it would sit at 28 V. The chart draws only the one. Anything taller than 28 V goes on the HPP+ side only. That includes the Jackery SolarSaga 500 X at 48.5 V and the rigid Renogy and Anker panels with it.

The pale cap on each bar is what a −10 °C morning adds, about 10%. Cold raises a panel's voltage. On a January morning on my deck I'd expect the Fluke to read a few volts above any label. On the HPP+ side the cap changes nothing. On the 8 mm side it does. The BLUETTI SORA 60 reads 27.5 V on its label and clears 28 on a cold morning, so it belongs on the big plug too.

Rest on a bar and it names its panel. If you own one that isn't here, type its Voc in the box below and it takes a place in the line.

A day on solar

How long the Yeti PRO 4000 takes to charge on solar

1.3 hours, if the full 3000 W ever came in. Nothing we track gets there, so the tick marks a pace this battery will rarely see. Two Renogy 590 W rigid panels in series deliver 850 W and need a little under five hours. Two Jackery SolarSaga 500 X panels, our pick for most people, deliver 720 W in five and a half hours and fold flat afterwards.

More likely you have a folding panel already. One 200 W panel gives about 144 W in real sun and takes about twenty-eight hours. One 100 W panel gives 72 W and takes fifty-five and a half. A good day has 3 to 6 hours of sun that strong. Call the 200 W panel a week of good weather, give or take. The 100 W panel is a forecast I wouldn't plan around. The system builder turns the hours into days for your state and month.

My first Goal Zero was a lead-acid Yeti that lost a good part of its charge to one cold Tahoe morning. This one has 3994 Wh of lithium iron phosphate and a cart. The sun is the slow part now.

Every panel that fits

Solar panels compatible with the Yeti PRO 4000

Thirty-one fit, none of them Goal Zero's own, because we don't track Goal Zero's panels yet. For each one: what a single panel delivers in good sun and the most the Yeti PRO 4000 will take from a set of them. The cable column is blank here. We haven't matched Goal Zero's adapters to these panels, and the manual's answer is that nearly any brand works through them. Most rigid panels end in MC4, the weatherproof snap-together plugs. Sorted by delivered watts.

Own a panel that isn't in the line-up?

Type its voltage into the door chart above for the height test, then put the rest of the label into the panel checker, already set to the Yeti PRO 4000, for current and plug too. Or build the whole system to see how it keeps up where you live.

The plain answers

How long does the Yeti PRO 4000 take to charge on solar?

One 100 W panel delivers about 72 W in good sun and refills the 3994 Wh battery from empty in about 55.5 hours.

One 200 W panel delivers about 144 W in good sun and refills the 3994 Wh battery from empty in about 27.7 hours.

At its 3000 W solar limit it refills in about 1.3 hours. More panel watts than that won't charge it any faster.

A day gives three to six hours of sun that good, depending on season and place, so one 100 W panel takes 10 to 19 days to fill it. The system builder works it out for your state and month.

What adapter does the Yeti PRO 4000 need for solar?

Every panel we track needs a cable to reach its Other:HPP+ and Other:8mm input. None comes in the box.

31 panels don't have a named plug from their maker, so check the lead before you buy a cable.

Can you use non-Goal Zero solar panels with the Yeti PRO 4000?

Yes. What decides it is the panel's voltage and plug, not the brand. 31 panels from Renogy, Jackery, Anker SOLIX, EcoFlow, BLUETTI, Eco-Worthy and Rich Solar work with it, as long as the panel stays under 145 V on a cold morning and starts above 12.3 V.

The strongest single panels here are the Renogy 590W N-Type Bifacial (425 W delivered) and the Jackery SolarSaga 500 X (360 W delivered).

Can you connect two solar panels to the Yeti PRO 4000?

Yes. It has 2 solar inputs, so the simplest way is one panel on each. Use the same panel model on both. Goal Zero's inputs share a controller, and mismatched panels hold each other back.

Wired in series, up to 2 BLUETTI PV100 FX Flexible panels fit under its 145 V limit, even on a -10°C morning. Series adds voltage; parallel adds current.

Past 3000 W delivered, more panels only help on cloudy days.

What is the Yeti PRO 4000's solar input?

HPP+ High Voltage Input (spec table: 'High Voltage DC'): 13.3–145 V, up to 30 A, 3000 W. 8mm Low Voltage Input (spec table: 'Low Voltage DC'): 12.3–28 V, up to 10 A, 275 W. 3000 W across all inputs together.

Input limits from Goal Zero's documents, checked 2026-09-18 (source). Delivered watts assume 72% of the panel's rating in good sun.
