Solar panels for the BLUETTI AC70

Written by Ian Schneider·Solar & Off-Grid Tester

BLUETTI's bigger stations take solar up to 60 volts. The AC70 stops at 58, and the manual's warning page says not to plug in a panel with an open-circuit voltage above that. Open-circuit voltage, Voc on the label, is what a panel puts out in sun with nothing connected to it. The two volts BLUETTI gave up turn out to cost nothing. Thirty-one of the forty-one panels we track publish a Voc. All thirty-one sit under 58, five of them BLUETTI's own.

The socket is an XT60, the yellow plug with a profile like a child's drawing of a house, and the spec row gives it two limits: 500 W and 10 amps. Nothing we track reaches the 500. The panels meet the 10 amps first. Two of Renogy's 590 W rigid panels come closest at 437 W, and two Jackery SolarSaga 500 X folders sit a step behind at 417 W. Either pair has 768 Wh full in a little under two hours of good sun.

A battery this size is one folding panel's work. A 200 W folder gives about 144 W and has the AC70 full in a little over five hours, which is a long day of good sun. For a weekend at the cabin I'd carry the one panel and spend Saturday morning finding it a spot the pines leave alone.

The door

Every panel we track, lined up at the AC70's solar input

Every panel we track with a published Voc, in a line by that figure. The black line is 58 V, where BLUETTI's warning begins. No bar gets there.

The pale cap on each bar is what a cold morning adds, about 10% at −10 °C. A panel's voltage climbs as the cells get cold, so a January label would read higher than a July one. The two volts BLUETTI trimmed from the window matter for one bar. Renogy's 590 W rigid reads 52.63 on the label, and its cap reaches nearer the line than anything else here. Still under. On my deck in January I'd have the Fluke on that one anyway, more from habit than worry.

The chart draws each panel alone. Two side by side, in parallel, keep that voltage and add their current, and the AC70 stops taking current at 10 amps. Point at a bar and it names its panel. If yours isn't here, type its Voc into the box below and the chart draws a bar for it.

A day on solar

How long the AC70 takes to charge on solar

An hour and a half with the input full, and nothing we track gets it there. Two of Renogy's 590 W rigids put the tick at a little under two hours. Two Jackery SolarSaga 500 X folders land in the same place and weigh 23.15 pounds each instead of 58.4. I know which pair my back would vote for.

One 200 W folding panel gives about 144 W and needs a little over five hours. One 100 W panel gives about 72 W and needs a little under eleven. A good day has 3 to 6 hours of sun that strong, so the 200 W panel is a long day's work and the 100 W panel runs into the next one. The system builder has the sun hours for your state by month and does the rest.

Every panel that fits

Solar panels compatible with the AC70

Thirty-one fit, five of them BLUETTI's own. For each: the cable that gets it to the XT60 socket, what one panel delivers in good sun, and the most the AC70 takes from a set. Eleven want an MC4-to-XT60 lead. MC4 is the pair of weatherproof snap-together plugs on the back of rigid panels and most large folders. I'd expect the cable in the box to be that lead, since the manual's FAQ asks for MC4 panels, but BLUETTI never names its connector pair. One panel, EcoFlow's 125 W modular rigid, plugs in with no adapter at all. 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 AC70, 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 AC70 take to charge on solar?

One 100 W panel delivers about 72 W in good sun and refills the 768 Wh battery from empty in about 10.7 hours.

One 200 W panel delivers about 144 W in good sun and refills the 768 Wh battery from empty in about 5.3 hours.

At its 500 W solar limit it refills in about 1.5 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 2 to 4 days to fill it. The system builder works it out for your state and month.

What adapter does the AC70 need for solar?

None, if the panel's plug is XT60: EcoFlow 125W Bifacial Modular plugs straight in.

The cables the other panels need: MC4 to XT60 (11 panels), DC8020 to XT60 (4 panels), Anderson to XT60 (3 panels) and DC5521 to XT60 (2 panels).

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 AC70?

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 58 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 AC70?

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 58 V limit. Parallel them instead.

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

What is the AC70's solar input?

DC Input: 12–58 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.
