Common questions

Is DELTA 3 Plus the same as DELTA 3?

They share the stated 1,024Wh capacity, but the Plus has different USB and solar-input specifications. This record uses the Plus / No Accessory UK variant.

Can DELTA 3 Plus feed the house like a STREAM battery?

No. DELTA 3 Plus is a portable power station with its own outputs. STREAM home-storage installation and household grid connection are separate matters.

Is the X-Boost figure its continuous AC rating?

No. Use 1,800W as the continuous AC rating. Surge and X-Boost figures describe other operating conditions and load limitations.
