How we assign awards →The differences that matter
- Maximum solar input: 1200 W vs 2400 W → the Apex 300 recharges faster from solar panels.
- Continuous output: 2400 W vs 3840 W → the Apex 300 runs more appliances together.
- Warranty: 6 years vs 2 years → the AC240 carries a longer manufacturer coverage.
- Ingress protection: IP65 vs IP20 → only the AC240 is protected for outdoor use against dust and water.
Which one to choose
Choose BLUETTI AC240 if…
Choose BLUETTI AC240 if you need a station that withstands dust and water jets (IP65), suitable even on a balcony or an open garage, with a longer warranty. The trade-off is a smaller starting capacity (1.5 kWh vs 2.8 kWh) and less power.
Choose BLUETTI Apex 300 if…
Choose BLUETTI Apex 300 if you need more power right away and want to expand capacity much further, up to over 21 kWh, in an indoor setting where IP20 protection is enough. The trade-off is shorter warranty.
