Confirm your delivery access before ordering. Expect curbside delivery on a liftgate truck — the carrier will not bring it into the garage. The casters make it manageable once it is on the ground and on a flat surface, but getting it off the truck and over a threshold is a two-person job. Inspect the crate before signing.\u003c\/p\u003e\u003cp\u003eClass 9 hazardous goods, ground or LTL freight only, no air, curbside delivery, someone must be present, excluded from free shipping.\u003c\/p\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eCan it run 240V equipment?\u003c\/strong\u003e\u003cbr\u003eYes. Output is split-phase 120\/240Vac and there is a dedicated 30A 120V\/240V outlet on the unit, alongside a 30A 120V and three 20A 120V outlets. That is the main thing separating this from portable power stations, which are almost all 120V only.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it UL listed?\u003c\/strong\u003e\u003cbr\u003eNot yet. The unit carries FCC SDoC; UL 9540 and UL 9540A certification is pending with POWISER. Until it is issued, treat this as an off-grid and plugged-loads unit rather than a grid-tied installation. If you intend to feed household circuits through a transfer switch or the HOME PANEL, wait for the certification and check what your local authority requires first. We will publish certificate numbers here as soon as POWISER supplies them.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it need an electrician?\u003c\/strong\u003e\u003cbr\u003eNot in the way a hardwired system does — it is a portable unit on casters rather than something bonded into your service panel. If you want it feeding household circuits through a transfer switch or the matching HOME PANEL, that connection does need a licensed electrician and requirements vary by jurisdiction. Note it is IP20 rated: indoor use only, not a carport or an exposed wall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much solar can I connect?\u003c\/strong\u003e\u003cbr\u003eTwo high-voltage MPPT channels take up to 10,000W combined at 32A per channel, with a 500Vdc open-circuit ceiling. Separately, a 1,300W low-voltage input accepts 12–60Vdc panels directly. Confirm the high-voltage operating window with us before sizing strings — the manufacturer’s documentation is inconsistent on that figure and we will not guess at it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is this different from the H12 PRO?\u003c\/strong\u003e\u003cbr\u003eSame 12kW split-phase output and the same 10 ms transfer. The H12 PRO mounts to a wall, hardwires into your panel and runs at 48Vdc. The ULTRA 12K rolls on casters at 51.2Vdc and plugs in. Choose the H12 PRO for a permanent whole-home install, the ULTRA if you want backup you can relocate — or take to a site, an RV or a second property. Their batteries are not interchangeable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I add more later?\u003c\/strong\u003e\u003cbr\u003eUp to six units run in parallel for 72kW.
