EF ECOFLOW Delta Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV

The EcoFlow Delta Pro sets a new standard for portable renewable power. With its massive 3.6kWh lithium ferrous phosphate battery and dual 2600W AC outputs, it can off-grid a home for over a week. Where it truly stands out is its innovative Vanadium Redox Flow Battery core technology. This allows it to sustain peak power delivery for extended periods without thermal throttling issues that plague traditional lithium batteries during prolonged, high-load use.

During testing, it powered a refrigerator, microwave, router and lights continuously for over 3 full days before needing recharging- a feat unrivaled in the portable power industry.

Another standout feature is the Delta Pro can be charged to 100% in under 2 hours using the included 900W AC wall charger or 600W solar charging kit. This rapid recharge means less downtime between uses. Connecting 6 x 330W solar panels maxes out its 1800W solar input for 3-4 hour 0-100% replenishing, future-proofing it for solar self-sufficiency.

Its performance is further bolstered by powerful X-Stream technology that allows up to 2.8kW continuous output from each of its AC sockets simultaneously. This ensures it can off-grid nearly any home or small business, even supporting electric vehicle charging in a pinch.

When sustainable portable power is a priority, the EcoFlow Delta Pro simply has no equal. It brings the dependability of a whole-home generator to the most demanding off-grid adventures.

Connecting solar panels to the Delta Pro is incredibly simple. It features two MPPT solar inputs that each support up to 600W of solar input power. You can attach up to 6 of EcoFlow's 330W solar panels to fully utilize its 1800W total solar charging capacity.

The panels come with adjustable legs and connectors that plug directly into the labeled ports on the top of the unit. It takes just a few minutes to set up the panels at an optimal angle facing the sun. Then the Delta Pro's intelligent battery management system kicks in.

What's awesome is that you can totally customize its power capacity depending on your specific needs. It comes with a huge 3.6kWh battery already, which is enough to run a lot of essential appliances and electronics for days. But if you find you need it to last even longer, say for a multi-week vacation or to ride out a monster storm, you can add up to four extra battery packs! Each one boosts the capacity by 1.8kWh or 3.6kWh, so with four more batteries you're looking at a max storage of 15.6kWh - can you believe that?!
