Sigenergy (PointGuard) Home system with generator input (Pro Power Onboard).

Does PG allow you to back-feed the grid with a bi-directional meter so you can take advantage of a utilities surge demand payment with the battery? (ie PGE has a program were they'll pay you to supply power back to the grid during high demand times)

Yes I believe it can. I have never tried it as I use only self consumption based on time of use but it does have an export mode for utilities that will pay you for exported power.

Wow, I'm impressed with this system! I want one . It seems very "plug and play" with impressive specs!

The only downside I can see is that the controller/inverter is always the top module, thus if you start with one battery the wiring and pipes will be at height 2. If you add another (or more) battery modules then the inverter height will change and the wiring/pipes will be too short. I guess you can "future proof" by leaving enough slack in the wiring and adjust the pipes as needed.

I understand why. The battery modules are 160 pounds each vs 77 for the controller/inverter. A fully stacked unit would be too top heavy to be safe.

The PointGuard components were just shy of $10k most of which is the batteries. The backup panel, extra breakers, generator inlet components and wire/conduit added about $1k more.
It was DIY so no labor cost.
I will get $3k back from the federal tax credit, and am also on a time of use plan, which will create a pretty fast ROI. That's why I got the extra battery capacity.
I already had a 5kW solar system which was about $12k fully installed 9 years ago, and has almost paid for itself already.

Now for someone to duplicate this with the minimum system possible (PG Load Hub, PG Inverter, PG 5kWh battery, generator inlet components) where you could do a whole home backup, I think you could get this down to about $6k in total equipment + whatever the labor would be. This assumes you just bring your meter connection to the load hub, and then the load hub to the existing panel. As of right now this would qualify for the tax credit.
This would get you about 9kW of continuous power with the truck and battery working together. This system is quite simple, so the install time is just a couple of hours assuming you don't have long cable runs. Full commissioning takes about 10 minutes.

The other option would be to just get the PG Load Hub, PG inverter, and PG V2X. It would cost about $500 more. Also without a battery it would only work while the truck is plugged in, but would be viable because it would also be your home charger, and the inverter would be the same labor as a normal home charger.

The nice thing about PG is how easy it is to expand later. I first installed mine with a single battery. It took me less than 20 minutes and no wiring changes to add the second battery in.

Would you say anybody, with basic electricity experience, could DIYit or you are an expert and that's why you could to it yourself? It would be nice to save on the installation costs if it's safe enough for me to do it. In my experience install costs for solar/home batteries are very expensive, almost overpriced because most battery systems don't distribute directly to consumers, so the installers take advantage of that excusivity. That's another nice feature of PoitGuard, that you are not "locked in" to the installers that are certified by the manufacturer.. Like Enphase and others..

So it is not technically DIY. It does require a certified installer. My friend is a master electrician and we both went through the courses.
it is extremely simple for people with good electrical knowledge and i did DIY the installation but my friend did check everything and we commissioned together on his login.
when signing up as an installer they do link to the license database for electrical licenses.
