Electric power from a hybrid, connecting inverter to the high-voltage system

Yes, everything is inside the battery case.

there has to be more in TIS right?

 

Literally a few weeks back had an offer accepted on a more locally found 89k miles Sienna HV battery, though I only want the newer modules or course.

Thinking I might have to make a post with a list of specific hybrid part number inverters that can be found that use the HV batteries with input specs if found.

Now wondering if two of the 1500W 120V inverters might be more cost effective, if found used, than the UPS's I invested in? Blah, lol

 

Had a similar issue with our anti Island'ing PV array that was designed to deliberately shut down once the grid crashed. Obviously that's because you don't want to backfeed when linemen are trying to bring the local system back up.
All our SunPower (2) PV inverters wanted to identify was single phase 60 cycle current, & then they were good to go. It didn't matter if it was 1KW or or 55kW's.
Once the grid was disconnected, & the pure sine wave EU 5500 Honda generator inverter hooked up to our grid disconnected home - the sun power inverters would re-sync w/ the Honda automatically - just like they would do with grid power - and the Honda would remain at an idol unless the solar panels could not provide enough power in the daytime for the house. Would it have been easier to have an array of batteries? Yeah, more expensive too.
It was just an emergency system that allowed our PV to run during daytime power outages, w/out batteries. We never drew more than 2½KW off the generator - even if the panels were providing 3 or KW of their potential 8kW.
The first time I threw the breaker for the back feed generator? I figure I had a 50/50 chance of blowing the generator to smithereens & was quite pleased when things went to plan.
Everonce in a while the generator (& thus PV array as well) inexplicably would shut down but would come back upon Honda restart.
Don't try this at home.

 

"We're not worthy..." oh great one. OK, more seriously, I have taken a mental note, praise we're thinking in phase and seriously once I get my hands on one then researching more on how is better (cost effective and smd scale quessing) to phase shift the two for a two leg "split phase" 240 source.

In regards to the more unobtanium (or astronomically high priced when available) Honda inverter modules for the older inverter generators, I recall I last left off with one where was thinking the Champion still on the market might do. Ideally reverse engineering the Honda potted to hen design and open sourcing, though yeah. However, the more I think about in relationship to the Post, taking the asynchronous (I think that is the term) Honda generator rectified output into one of these higher voltage inverter systems might be a valid work around. Wondering which inverter might be the better of them? Of course the controls to start the generator, confirm start and actuate the choke-throttle will need to be designed as seems is all integrated in the potted magic module if I recall correctly.
