As part of its ongoing Members’ Festival x Earth Day Mega Sale, EcoFlow has launched a 24-hour flash sale window that is taking up to 61% off two expansion batteries and a solar generator bundle. That latter bundle gives you EcoFlow’s DELTA 3 Ultra Plus Portable Power Station with a 500W bifacial modular solar panel kit (4x 125W panels) for $1,799 shipped, with the closest match at Amazon being this 400W panel bundle sitting $200 higher in price. This package would run you $3,798 at full price, with the current discounts during this sale still tallying up to $2,148 were you to buy the station and panel kit separately. Up until today, the few inclusions we’ve seen of this bundle in sales only fell as low as $1,999, but you’re getting a bigger-than-ever 53% markdown that saves you $1,999 off the full MSRP for the lowest price we have tracked. Head below to check out the two additional expansion battery deals for the DELTA Pro and DELTA 2 Max stations.
The DELTA 3 Ultra Plus power station is the big boss of EcoFlow’s DELTA 3 series, bringing along a sizeable 3,072Wh starting LiFePO4 capacity that you can further scale up to 11kWh using multiple different expansion batteries for stations across the series, making it as modular a solution as its included solar panels. Through 11 output ports (5x AC, 3x USB-C, 1x USB-A, 1x DC, and a car port) it provides up to 3,600W of steady power that can be boosted to 4,600W or surge up to a 7,200W maximum.
As I mentioned, you’re getting a modular 500W solar panel package here, which you can use together or break up into four 125W panels, too – all the way up to a 1,600W max input for recharging needs. Alongside the solar charging, you’ll also be able to recharge with an AC outlet, using a gas generator or alternator charger, a car auxiliary port (which is the slowest option), or even two different simultaneous options (solar + generator, solar + alternator charger).
