Every BLUETTI station has a solar input with three limits: the most watts it will use, a voltage window, and a current rating. The voltage limit is the one that matters most: BLUETTI's manuals state it as a do-not-exceed. The wattage figure is the most the station will use. This page lists the limits BLUETTI publishes for each model we carry. It then shows how many of BLUETTI's own panels you can wire in series on each one before you hit the voltage ceiling.
Solar input limits by model
| Station | Most solar it will use | Voltage window (Voc) | Current rating |
|---|---|---|---|
| Premium 100 V2 | 1,000W | 12–60V | 20A |
| Premium 200 V2 | 1,000W | 12–60V | 20A |
| Elite 320 (our listing) | 1,000W | 12–60V | 20A |
| FridgePower | 1,000W | 12–60V | 20A |
| Pioneer Na | 500W | 12–60V | 10A |
| AC200P L | 1,200W | 12–145V | 15A |
| Apex 300, built-in inputs | 2 × 1,200W = 2,400W | 12–60V per input | 20A per input |
| Apex 300 + SolarX 4K | up to 4,000W more (6,400W in total, BLUETTI's figure; see the note below) | 150–500V into the SolarX | See BLUETTI's notes below |
Two other chargers take solar as well. The Charger 2 accepts up to 600W of solar and blends it with alternator power, up to 1,200W in total, with solar taking priority. The RV5 system has its own PV input, but BLUETTI's US product page does not print a wattage limit in its text. BLUETTI's own RV5 kits pair it with two, four or six PV100 FX panels, and BLUETTI's PV100 FX FAQ says its RV solar system supports up to 16 of them (1,600W). Check the RV5 manual, or ask us, before planning anything larger.
BLUETTI's panels, by the numbers that matter
| Panel | Rated | Open-circuit voltage (Voc) | Short-circuit current (Isc) | Connector |
|---|---|---|---|---|
| PV200 folding | 200W | 24.6V | 10.8A | MC4 |
| PV350 folding | 350W | 44V on BLUETTI's spec table | 11.4A | MC4 |
| SORA 500 folding | 500W | 49.1V | 13.31A | MC4 |
| SP100L folding | 100W | 24.62V | 5.13A | MC4 |
| PV100 FX flexible (sold as a 2-pack) | 100W each | 41.4V | 3.05A | MC4 |
| SORA 60 | 60W | 27.5V | 2.76A | DC5521, not MC4 |
One inconsistency to know about. The text on BLUETTI's 350W panel page says 33V Voc, but the spec table on the same page says 44V. Plan with the higher figure.
How many panels in series?
In series, the voltages add. In parallel, the currents add. So the question for each panel is how many you can string together before the total Voc passes the station's ceiling. We used BLUETTI's Voc figures and divided:
| Panel | Most in series on a 60V input | Most in series on the AC200P L (145V) |
|---|---|---|
| PV200 (24.6V) | 2 (49.2V) | 5 (123V) |
| SP100L (24.62V) | 2 (49.24V) | 5 (123.1V) |
| PV350 (44V) | 1. Two would be 88V | 3 (132V) |
| PV100 FX (41.4V) | 1. Two would be 82.8V | 3 (124.2V) |
| SORA 500 (49.1V) | 1. Two would be 98.2V | 2 (98.2V) |
Leave yourself headroom. Panel voltage rises in cold weather, so a string that sits just under the limit on paper can go over it on a frosty morning. Above one panel per string on a 60V input, wire the strings in parallel instead, for example with an MC4 Y-branch pair.
What about current?
Paralleling panels adds their current. BLUETTI's own kits show that the station limits how much current it takes, rather than treating the rating as a hard ceiling. For example, BLUETTI sells the Pioneer Na in a kit with its 200W panel, the PV200, whose 10.8A short-circuit current is above the station's 10A rating. The voltage limit is different. The Pioneer Na manual and the FridgePower manual both tell you not to use panels whose open-circuit voltage is above 60V. If you plan to parallel panels whose combined current is well above the input rating, ask us first.
Reaching the full 1,000W on a Premium or Elite 320
On a 12–60V input it is hard to reach 1,000W with folding panels. Two SORA 500s cannot go in series, because together they are 98.2V. In parallel their Isc adds up to 26.62A. In practice, BLUETTI sells the Premium 100 V2 and Premium 200 V2 with one 200W or one 350W panel. Plan on a few hundred watts from a portable array, and treat 1,000W as the most the station will accept.
The Apex 300: two inputs and the SolarX 4K
The Apex 300 has two XT60 solar inputs, each rated 1,200W at 12–60V and 20A. BLUETTI recommends wiring panels in parallel on those inputs. One SORA 500 per input is a straightforward fit, and BLUETTI sells that pairing as the Apex 300 + 2x 500W bundle.
For a large array, the SolarX 4K takes high-voltage strings of 150–500V. Charging does not start below 150V. BLUETTI's notes on the SolarX:
- At least one B300K expansion battery is required.
- The full 4,000W needs the short CA90 cable. On the long cable, BLUETTI quotes 3,000W on one page and 3,000–3,500W on another.
- BLUETTI's Apex 300 page also says a single Apex 300 takes up to 3,200W from the SolarX 4K, while its SolarX FAQ gives 4,000W for an Apex 300 with a B300K. Ask us before you size a large array around one unit.
- Its single MPPT input means you cannot mix panel types.
- Its own example is up to 12 panels in series for a 350W panel.
Add the two built-in inputs and BLUETTI's published maximum is 6,400W. On a single Apex 300 at the 3,200W figure, that would be 5,600W. Our expansion battery guide covers the B300K side.
How much solar do you actually need?
Use this rule: daily watt-hours ÷ (4 to 5 peak sun hours × 0.75 for real-world losses). To replace 1,000Wh a day, that comes to about 270–330W of panel. Our RV solar and battery calculator does the sum for your loads, and our BLUETTI sizing guide works through it station by station.
FAQ
Can I use non-BLUETTI panels?
Yes. BLUETTI says third-party panels work if they stay inside the station's voltage window, stay under its wattage limit and use MC4 connectors. On the Apex 300, you need an MC4-to-XT60 or Anderson-to-XT60 cable.
Why does my station show less than the panel's rating?
A panel's rating is a lab figure. Heat, sun angle and cable losses all cut the output. That is why our sizing rule includes the 0.75 factor.
Can I charge from solar and the wall at once?
On most models, yes. BLUETTI lists AC plus solar charging for the Premium 100 V2 (1,200W combined), the Premium 200 V2 (2,400W), the Pioneer Na (1,900W) and the AC200P L (2,400W). For solar and alternator together, see can a BLUETTI take solar and alternator at the same time.
Is the SORA 60 an MC4 panel?
No. BLUETTI lists a DC5521 connector, so check your station's input before you buy it.
