BLUETTI Apex 300

The Apex 300 in brief

Split-phase output is listed as yes for the Apex 300, alongside 3,840 W of AC power from a 2,764.8 Wh LFP battery. It has the longest rated cycle life of the 13 stations in the 2,500 to 4,000 Wh class, at 6,000 cycles to 80% capacity. Wall charging also runs at 3,840 W, so a refill takes about 0.7 hours, and up to 2,400 W of solar through the XT60 port refills it in about 1.5 hours. The case weighs 83.78 lb. Add-on batteries (B300, B300S, B300K and B500K, up to 6) can raise the system to 19,353.6 Wh, and BLUETTI gives a 5-year warranty and a 20 ms UPS switchover.

How long the Apex 300 runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. About 2,350 Wh is usable, so a refrigerator runs 26 to 67 hours and a chest freezer 59 hours to 4 days. At 3,840 W, no listed appliance is held back by output, the circular saw and sump pump included.

Work out your own mix of loads. A red bar means it draws more than the 3,840 W this station can supply.

How fast it refills

Solar time assumes panels reach 75% of their rating. Figure it for your state and panels.

Solar panels for the Apex 300

Its XT60 port takes 12 to 60 V, up to 20 A and 1,200 W. A panel's voltage rises in the cold, so the marks below show each one at 14 F, and a pass here keeps 10% of headroom under the maximum.

All 2 of its inputs: input 1 XT60 (12 to 60 V, 1,200 W); input 2 XT60 (12 to 60 V, 1,200 W).
