A single source to power almost all of your essential home appliances. Power high-demand appliances with robust 8000W and dual 120V/240V capabilities. Keep your kitchen buzzing and essential systems like garage doors running, all powered simultaneously and reliably by EcoFlow.
So I think it does double the wattage when connected.
It makes sense since this bundle includes the hub that connects the 2 together. Otherwise, what's the point.
Is the 3k estimate comparable as DIY to this 5k plug n play option? And if yes, 2k price difference is a ton...is the diy option that much more difficult/challenging?
Additionally, there's more to these than just a battery/inverter. There's also the AC charge controller, solar charge controller, and all other I/O (e.g. USB) in one tidy little package, not to mention the app which is pretty handy to have for monitoring / automation.

Get " Ampinvt 3000W Peak 9000W" which is a pass through inverter with auto switchover.
4*$170 = $680 for 4.8 kwh battery.
$50 for wiring (conservative estimate)
$50 for USB chargers
Ampinvt inverter choices:
3000w 24v: $525, maximum 900 watt charging, no solar. Total: $1305
5000w 48v: $715, maximum 1700 watt charging, 240 volt input only, no solar. Total: $1495
6000w 48v: $835, maximum 1700 watt charging, 120 or 240 volt input options (not changeable after buying), no solar. Total: $1605
If you want to add solar charging, there are two options: PWM or MPPT.
PWM charger: ~$50 for up to 2900 watts, lose up to 25% of power depending on setup and conditions. Also far more complicated to properly set up.
MPPT charger: $100-150 for up to 2800 watts.
So yes, you can save up to half by DIY (you can actually save more by buying your own cells), but that requires sacrificing many of the features bundled in the Ecoflow unit. Once you get up to the same feature level, it becomes a question of whether or not saving $800 is worth the time investment (probably at least one whole day to put everything together) and a significantly less convenient form factor.

Now the DP refurb has gone as low as about 1700 each, which then might make the cost savings worth it if (big IF) it qualifies for the tax credit. as a refurb (jury is still out).
