Anker SOLIX C300 DC vs BLUETTI AC240P
The Anker SOLIX C300 DC (288Wh) and BLUETTI AC240P (1,843Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? The AC240P has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the AC240P's 2,400W inverter can run a window AC unit, a full-size fridge, or power tools. The SOLIX C300 DC's 300W inverter will flat-out refuse to start those appliances. On stamina, the AC240P keeps a fridge alive for roughly 10 hours vs the SOLIX C300 DC's 2 hours. The cost? Portability. At 72 lbs, the AC240P is heavy enough to make you think twice about moving it. The SOLIX C300 DC at 6.2 lbs is something one person can actually carry.
Pick the AC240P if your primary use is cpap overnight or remote workday. Go with the SOLIX C300 DC if you need the heavier-duty specs for demanding loads. Most buyers overlook this: the SOLIX C300 DC costs ~$0.2/kWh over its full lifespan, which adds up significantly over years of regular use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

Strengths
- Larger Battery Capacity
- Higher AC Output Power
- Longer Warranty Coverage
- Faster Solar Charging
Trade-offs & Considerations
- Substantially more expensive (+$1,769) than the SOLIX C300 DC.
- Significantly heavier (+65.8 lbs), making it harder to move.
What the Specs Don't Tell You
Hidden gotchas and advantages we spotted that you won't find on the product page.
AC240P: 72 lbs Is a Commitment
NoteAt 72 lbs, this is manageable but not fun to carry. That's heavier than a large checked suitcase. Moving it from your car to a campsite requires some effort and flat terrain.
AC240P: 45dB Under Load
Note45dB is about as loud as a running refrigerator. If you're running a CPAP or sleeping near this unit, the fan noise may be noticeable. Most people find anything above 45dB disruptive for sleep.
SOLIX C300 DC: No Expansion Path
Watch outThe SOLIX C300 DC is a closed system. The 288Wh you buy today is the ceiling. If your power needs grow (more gear, longer trips, partial home backup), you'd need to buy a completely new unit. The AC240P can add expansion batteries.
Only the AC240P Has UPS Protection
AdvantageThe AC240P can act as an uninterruptible power supply. Plug your PC, router, or CPAP into it and it switches to battery seamlessly during an outage. The SOLIX C300 DC doesn't have this feature, so connected devices will experience a power interruption.
Warranty Value Comparison
NoteThe SOLIX C300 DC gives you 17.6 years of warranty per $1,000 spent, vs the AC240P's 3.1 years. That's 5.7× more coverage per dollar. An underrated factor if you're keeping this unit for years.
SOLIX C300 DC: Noise Level Not Disclosed
Watch outThe AC240P publishes its noise level (45dB), but the SOLIX C300 DC doesn't. Brands that don't disclose noise specs often have louder units. If noise matters to you (CPAP users, apartment dwellers), this is worth investigating before buying.

Growth Path
SOLIX C300 DC
🔒 Closed SystemClosed system. What you buy is what you get. If your needs outgrow 288Wh, you'll need to purchase an entirely new unit.
Accepts up to 100W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
AC240P
✓ ExpandableSupports expansion batteries from BLUETTI. You can increase capacity without replacing the base unit. A significant long-term advantage.
Accepts up to 1,200W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are BLUETTI-specific. You're investing in the BLUETTI ecosystem.
If your power needs might grow (more camping gear, longer trips, partial home backup), the AC240P's expansion path saves you from buying a whole new unit in 2 years. That flexibility has real dollar value.

Frequently Asked Questions
SOLIX C300 DC vs AC240P — answered by our testing team.
Q.Is the AC240P worth $1,769 more than the SOLIX C300 DC?
The short answer: yes, if you'll actually use the extra capability. The AC240P costs $1,769 more, but that premium buys you 1,555Wh more battery capacity (that's 9 extra hours of running a mini-fridge); 2,100W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 3,500 cycles — that's 10 years at daily use; 1,100W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $1.05/Wh vs $0.59/Wh. For regular use, we'd pay the premium.
Q.How does the 1,555Wh capacity difference actually affect daily use?
The AC240P's 1,843Wh battery keeps a mini-fridge running for roughly 10 hours vs the SOLIX C300 DC's 2 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The AC240P's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Q.Can I actually carry the AC240P, or is the SOLIX C300 DC the only portable option?
The SOLIX C300 DC at 6.2 lbs is genuinely grab-and-go. Toss it in a backpack, carry it one-handed to a picnic, take it on a boat. The AC240P at 72 lbs is a different story. It's like carrying a large suitcase full of books. If you're setting up and breaking down camp frequently, this weight difference will exhaust you by day two.
Q.How fast can each unit recharge from solar panels in real conditions?
On paper, the AC240P accepts 1,200W vs the SOLIX C300 DC's 100W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 2.2 hours for the AC240P and 4.1 hours for the SOLIX C300 DC. That gap widens on cloudy days, when the AC240P's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the AC240P's advantage is substantial.
Q.Can I use the AC240P as a home UPS to protect my electronics during blackouts?
Yes. The AC240P has UPS mode that keeps your devices running through power transitions. Plug in your desktop PC, router, NAS, or CPAP machine and it switches to battery seamlessly when the grid drops. The SOLIX C300 DC does not have this feature. Without UPS, a blackout means: your PC reboots (potentially corrupting unsaved work), your NAS may corrupt its drive array, your CPAP alarms and wakes you up, and your security cameras go dark until you manually switch them over. If always-on power protection matters, this is a dealbreaker advantage for the AC240P.
Q.What happens if I outgrow the SOLIX C300 DC's 288Wh capacity?
With the SOLIX C300 DC, you'd need to buy an entirely new power station. It's a closed system with no expansion port. The AC240P supports BLUETTI-compatible expansion batteries that can double or triple your total capacity without replacing the base unit. Say you start with weekend camping and six months later you want to run a mini-fridge full-time in a van. The AC240P scales with you. The SOLIX C300 DC forces a repurchase. Worth considering even if you don't need more capacity today. Power needs tend to grow.
Q.Is Anker or BLUETTI more reliable for long-term ownership?
Both brands have strengths and trade-offs. Anker: 5-year warranty standard on portable stations, 10-year on home energy systems. Historically very reliable, though some recent firmware updates have altered product functionality without notice or rollback option. BLUETTI: Check manufacturer warranty policy directly One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Q.Bottom line: should I buy the SOLIX C300 DC or the AC240P?
We'd pay the premium for the AC240P. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The SOLIX C300 DC is still solid if budget is the priority, but the AC240P will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
