How big and heavy is the Elite 400?

The Elite 400 weighs 85.98 lb, and it measures 16.8 in long, 11.3 in wide and 19.3 in tall. That puts it in the heavy (over 50 lb) class, and BLUETTI equips it with a pull-out handle and wheels. Inside is a 3840 Wh LFP battery with 2600 W of continuous AC output and a power lifting figure of 3900 W.

It has 4 AC outlets, 2 USB-A ports, 2 USB-C ports and 1 car port. The screen is readable in direct sunlight. Solar comes in at 1000 W through an xt60 port, and capacity divided by that input works out to 3.8 hours before losses.

Its UPS switchover is listed at 15 ms at most, and it cannot add batteries.

What does the Elite 300 offer for solar charging?

The Elite 300 lists 1200 W of max solar input through an xt60 port. It lists a minimum MPPT voltage of 12 V and a max input voltage of 60 V. The max input current is 22 A.

BLUETTI also lists third-party solar panels as supported: yes. Dividing its 3014 Wh battery by that solar input gives 2.5 hours for a full refill before losses, and from a wall outlet the AC input is 1800 W. The price is $1,199.00 at BLUETTI, which ranks #2 of 7 at 2.51 Wh/$.

It weighs 57.98 lb, has 2400 W of continuous AC output, and its UPS switchover is listed at 10 ms at most.

What are the Elite 200 V2's wall and solar charge times?

BLUETTI lists 1.4 hours in turbo mode for a wall charge of the Elite 200 V2. Standard mode is listed at 1.6 hours, and silent mode at 3 hours. With 1000 W of solar, the maker lists 2.4 hours.

Simple math, capacity divided by max solar input, gives 2.1 hours before losses. The battery is 2073.6 Wh, and it costs $899.00 at BLUETTI. That ranks #3 of 7 at 2.31 Wh/$.

Continuous AC output is 2600 W, with a power lifting figure of 3900 W, and the unit weighs 53.35 lb. BLUETTI lists runtime inputs of 90 % depth of discharge, 85 % minimum inverter efficiency and 10 W of self use.

How much power can the DELTA 3 Ultra Series put out?

EcoFlow lists 3600 W of continuous AC output for the DELTA 3 Ultra Series, plus 7200 W of surge. Behind that output sits a 3072 Wh battery with LFP chemistry. It stands 24.6 in tall, with a footprint of 15.6 in by 12.9 in, and it weighs 72.1 lb.

It has 2 ports for solar and lists 800 W as max solar input, which works out to 3.8 hours for a full refill by capacity divided by input, before losses. The UPS switchover is listed at 10 ms at most. In the cold, it does not charge below 0 °C, but it can discharge down to -10 °C.

At EcoFlow it costs $1,349.00, ranking #4 of 7 at 2.28 Wh/$. The warranty is 5 years: that is 3 years as standard, plus 2 more when you register it in the EcoFlow app.

Can you add batteries to the DELTA 2 Max?

Yes, the DELTA 2 Max can add batteries, and the unit itself holds 2048 Wh. It also has 6 AC outlets, 4 USB-A ports, 2 USB-C ports and 1 car port. Output is listed at 2400 W continuous and 4800 W surge.

It has 2 ports for solar and lists 1000 W as max solar input, and capacity over that input comes to 2.0 hours before losses. EcoFlow prices it at $1,029.00, which ranks #5 of 7 at 1.99 Wh/$. The UPS switchover is listed at 20 ms at most, and the unit weighs 50.7 lb, measuring 19.6 in by 9.5 in by 12 in.

How much solar can the Apex 300 Versatile take in?

What should you check before buying a high capacity power station?

Start with the battery size you need, then compare watt-hours per dollar. If the unit will move between rooms or into a truck, look at weight and whether it has wheels. Plan how you will charge it, since solar input and wall input set how quickly a large battery refills.

For backup use, compare the listed UPS switchover time and check for pass-through charging. Check the charging temperature range if the unit will sit in a cold garage or shed. If you think your needs may grow, look for battery expansion.
