here it is:
This inverter is a new model, and it is different from the 5kW all-in-one inverter/charger units we've sold in the past.
It is specifically designed for North American split-phase systems, which means it supports 240V split-phase output.
It also requires a 240V split-phase AC input — 120V single-phase input is not supported.
For safety and optimal performance, please ensure that both the input and output connections follow the required 240V split-phase standard.
You will still need to find a way to wire up outlets to this, but it is very easy and there are a few options.
You could just cut the end off of an extension cord (get one with multiple plugs on the end), wire it up as per the instructions and just use it to plug a few local devices into it.
OR
You can use a length of standard house wire and plug it into a power distrubution box like this- https://www.amazon.com/Distributi...R3
OR
You can wire the unit up to a transfer switch or load panel that will be wired directly into your homes wiring.
It can be as permanent or as mobile as you want
Heres a picture of a DIY permanent installation and pictures(s) of a portable unit someone built into a hand truck system:
If by Off grid you mean you had plans to back feed a grid connect, you absolutely shouldn't be doing that as your utility will allow only specific brands to connect to it and eco-worthy definitely won't be on that list because they rebadge, so no, it doesn't have the ability to back feed a grid.

For the plug and play, a delta pro is a monolith - something, even a little cable inside it dies and you need to RMA it if in warranty or throw it out if outside.
