Differences Anker SOLIX F3800 vs Bluetti AC500
Below is a summary of the specifications:
Battery Capacity, Expandability, and Battery Lifespan
The Anker SOLIX F3800 is equipped with a massive 3,840Wh LFP battery, offering more usable power right out of the box than the Bluetti AC500. Its standout feature is its extreme scalability—users can connect up to 6 expansion batteries, reaching a staggering 26,880Wh, a capacity capable of supporting an entire household or multi-day off-grid usage without any compromise.
In contrast, the Bluetti AC500 is a modular system that requires pairing with at least one B300S battery (3,072Wh). While the base AC500 unit has no built-in battery, its expansion capability is impressive, allowing connection with up to 6 B300S units, for a total capacity of 18,432Wh. Like the F3800, it uses LiFePO₄ chemistry, but edges slightly ahead in lifespan with over 3,500 cycles to 80% capacity.
Winner: Anker SOLIX F3800
With a larger base battery and unmatched expandability to 26.8kWh, the SOLIX F3800 delivers superior scalability and whole-home backup potential.
Power Output and Device Compatibility
The Anker SOLIX F3800 delivers a game-changing 6,000W of continuous AC output, supporting both 120V and 240V split-phase output natively. This makes it a seamless fit for high-demand appliances like HVAC systems, well pumps, dryers, and even electric vehicle charging. With dual voltage support, it can also serve mixed household loads more effectively than most competitors.
The Bluetti AC500 provides a respectable 5,000W of continuous output with an enormous 10,000W surge capacity, especially useful for inductive loads with high startup requirements. It also supports 240V split-phase setups when paired with another AC500 and a Fusion Box, but that requires more components and setup complexity.
Winner: Anker SOLIX F3800
With higher continuous output, built-in 240V split-phase support, and broader compatibility for whole-home systems, the SOLIX F3800 dominates in raw power delivery.
Charging Speed and Solar Input
The Anker SOLIX F3800 offers 2,400W AC input for fast wall charging and supports 2,400W solar charging through MPPT, allowing users to fully recharge from solar in just 1.5–2 hours under optimal conditions. This makes it one of the most capable solar-integrated power stations on the market for both home and off-grid solar systems.
The Bluetti AC500, when paired with its companion batteries, offers up to 3,000W AC input and 3,000W solar input, delivering extremely fast recharge times, especially when combining solar + grid input. Its intelligent charging algorithms further optimize input efficiency across dual power sources.
Winner: Bluetti AC500
While Anker is impressive, Bluetti edges out in charging power with higher combined input potential and advanced multi-source recharge support.
Ports and Output Variety
The Anker SOLIX F3800 includes two 100W USB-C ports, two USB-A ports, a 12V car port, and multiple AC outlets supporting 120V and 240V loads directly. It also features NEMA 14-50 and L14-30 outputs, essential for heavy-duty appliances and backup systems, and supports EV charging directly without needing adapters.
The Bluetti AC500 also offers a strong I/O selection with multiple AC outlets, one 100W USB-C port, two 18W USB-A QC 3.0, 12V car port, and RV 30A port. When fully expanded, the AC500 provides numerous outputs, but some require optional accessories or battery modules to activate.
Winner: Anker SOLIX F3800
Anker provides more powerful AC ports out of the box, including EV-specific outlets and 240V NEMA support without additional hardware.
Portability and Weight
The Anker SOLIX F3800, while heavy at 60 kg, integrates rugged wheels and a suitcase-style handle, enabling easy maneuverability despite its size. This makes it a rare combination of ultra-high capacity with portable design, even at this scale.
The Bluetti AC500, at 30.8 kg for the AC unit alone, is lighter but requires additional batteries like the B300S (each 38 kg) for full operation. Transporting multiple components separately may be more difficult for users who value compact all-in-one systems.
Winner: Anker SOLIX F3800
Despite being heavier, the wheeled design and integrated form factor make it easier to move than Bluetti’s multi-part modular system.
Connectivity and Smart Features
Both units feature Wi-Fi and Bluetooth connectivity, with dedicated mobile apps for power management, firmware updates, input/output monitoring, and remote operation.
The Anker App allows real-time monitoring, smart power scheduling, and custom output configurations with intuitive control from any connected device.
The Bluetti App offers comparable features including multi-unit synchronization, firmware updates, and power statistics, though its full feature set is unlocked only when connected to batteries and additional modules.
Winner: Tie
Both Anker and Bluetti deliver robust smart control ecosystems, offering real-time management and seamless integration for advanced users.
