Solar panels for the BLUETTI AC180P

Written by Ian Schneider·Solar & Off-Grid Tester

The AC180P takes solar through a barrel jack, the round plug a laptop charger ends in. The manual's spec table calls it DC7909, and the same socket takes the cigarette-lighter cable when you charge from the car. BLUETTI rates it for 12 to 60 volts, 10 amps and 500 W, then adds a warning in brackets. Over 60 volts damages the device, and the warranty does not cover it.

Thirty-one of the forty-one panels we track publish a voltage, five of them BLUETTI's own, and all thirty-one come in under 60. None of them fills the port, alone or in a set. Two of Renogy's 590 W rigid panels come closest at 437 W. The socket stops taking current at 10 amps, and with panels this size that limit arrives before the 500 W one.

That pair has the 1440 Wh battery full in a little over three hours of good sun. One 200 W folding panel gives about 144 W and needs about ten hours. For a weekend at the cabin I'd bring two of those, set them out at breakfast on Saturday, and read the screen after dinner.

Every panel we track, lined up at the AC180P's solar input

Every panel we track with a published voltage, in a row by that figure. It is the open-circuit voltage, Voc on the back label, what a panel puts out in sun with nothing plugged into it. BLUETTI's manual asks for the same figure by the same name in its solar section, so the sticker and the manual are reading one number. The black line is 60 V. Nothing in the row reaches it.

The tallest bars are not the biggest panels. EcoFlow's 125 W modular rigid reads 50 V on its label, more than Jackery's 500 W SolarSaga at 48.5. Volts and watts keep separate books. The pale cap on each bar is what a cold morning adds, about 10% at −10 °C. Cold pushes a panel's voltage up, and the cap is my deck in January. Both of those panels stay under 60 with it.

Hover a bar for the panel's name. The field below takes the Voc off your own panel's label and stands it in the row, cap and all.

A day on solar

How long the AC180P takes to charge on solar

The strip is a day of sun, and the tick marks the hour the battery is full. With the input full at 500 W that tick sits a little under three hours out. Nothing we track gets the input there, so that mark is the floor. One 100 W folding panel gives about 72 W in real sun and needs about twenty hours. A 200 W panel gives 144 W and needs about ten.

A good day has 3 to 6 hours of sun that strong. The 200 W panel is a couple of good days, more if the pines get a say. The 100 W panel is most of a week. The system builder does that calendar for your state and your month.

Every panel that fits

Solar panels compatible with the AC180P

Thirty-one fit, five of them BLUETTI's own. For each: the cable it needs to reach the barrel jack, what one panel delivers in good sun, and the most the AC180P takes from a set. The sets are wired side by side, in parallel, so the voltage stays at one panel's worth. Eleven want an MC4-to-DC7909 lead, MC4 being the weatherproof snap-together pair most panels end in, and the product page FAQ asks for MC4 by name. The same FAQ names BLUETTI's own picks: one PV420, one PV350, or two PV200. We track the last two. 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 AC180P, 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 AC180P take to charge on solar?

One 100 W panel delivers about 72 W in good sun and refills the 1440 Wh battery from empty in about 20 hours.

One 200 W panel delivers about 144 W in good sun and refills the 1440 Wh battery from empty in about 10 hours.

At its 500 W solar limit it refills in about 2.9 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 4 to 7 days to fill it. The system builder works it out for your state and month.

What adapter does the AC180P need for solar?

Every panel we track needs a cable to reach its DC7909 input.

The cables they need: MC4 to DC7909 (11 panels), DC8020 to DC7909 (4 panels), Anderson to DC7909 (3 panels), DC5521 to DC7909 (2 panels) and XT60 to DC7909 (1 panel).

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

Can you use non-BLUETTI solar panels with the AC180P?

Yes. What decides it is the panel's voltage and plug, not the brand. 26 panels from Renogy, Jackery, Anker SOLIX, EcoFlow, Eco-Worthy and Rich Solar work with it, as long as the panel stays under 60 V on a cold morning and starts above 12 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 AC180P?

Yes, joined into one input with a series or parallel cable.

Don't wire two BLUETTI PV100 FX Flexible panels in series: together they would pass its 60 V limit. Parallel them instead.

Past 500 W delivered, more panels only help on cloudy days.

What is the AC180P's solar input?

DC Input: 12–60 V, up to 10 A, 500 W.

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